An appropriation is considered to be made when one constructs facilities to divert water and uses that water in some beneficial way. The uses of the water are defined by the State's constitution as domestic, agricultural , and manufacturing. The same document also assigns the general priorities of water uses corresponding to the order named just above. After making an appropriation the appropriator has the option of applying to the court for an adjudication of his appropriation. The court reviews the pertinent facts and claims made in connection with the appropriation, and if satisfied with the means of diversion,the amount of diversion, and the use of the water, it will issue a water right in the form of a court decree. The following elements are essential parts of a water right: location of the diversion structure, means of diversion, amount of diversion, date of appropriation, and the use for which the diversion is made. In addition to these, the court decree will also determine the priority date of the water right that is essential to its future administration. Colorado is one of the states that has adopted the prior-appropriation . doctrine in the distribution of its waters. The prior-appropriation doctrine simply expressed follows the first-in-time, first-in-right principle. As this applies to administration, as the natural flow of the rivers diminish after the snowmelt runoff, and a water shortage develops for all the appro- priations on that stream, the most junior water right will first experience that shortage. As the water supply diminishes, the second junior, then the third junior, etc. , will be prevented from diverting water in order to satisfy the more senior appropriators. The more junior water rights are generally referred to in common terminology as "flood rights" indicating that diversions by these water rights are generally possible only at times when the rivers carry substantial amounts of flood waters. • -1- RESOURCE CONSULTANTS INC In determining the priority of the water right two factors are considered • by the courts. The first one is the appropriation date being the date when water was first applied to beneficial use by applicant claiming that water right. The second issue concerns itself with the already awarded water rights that, since they were decreed earlier, must be senior to any water right awarded thereafter. This clearly implies that if an appropriator has made an early appropriation, however did not obtain a water right for the appropriation at the earliest possible date, his water right will be junior to all of those, regardless of appropriation date, that were awarded by the courts at an earlier date. The administration of the water rights was assigned to the Colorado State Engineer and today it represents one of the most important duties of that office. In discharging these duties, the State Engineer must assure that the waters of the State are distributed according to the prior- .appropriation doctrine among the water rights, that no illegal water diver- sions are being made, that the waters diverted under the priorities are used for the decreed purpose, that no waste of water occurs and that the waters diverted under the various priorities are truly needed for the decreed beneficial use. Furthermore, the State Engineer is assigned the duty of keeping official records of the diversions made by the numerous water rights. In order to discharge his statutory duties, the State Engineer has subdivided the State into water divisions. Each division coincides with the hydrologic watershed area of the major river basins of the State with some minor exceptions warranted by localized hydrologic conditions or admin- istrative considerations. Each water division has a division office headed by the Division Engineer directly subordinated to the State Engineer. The Division Engineer, besides his office staff, directly supervises the Water Commissioners working within his division. Prior to 1969 each division was subdivided into numerous water districts generally coinciding with the major tributaries of the main river of the division or with some logically selected arbitrary subdivision of the main stem. The Water Commissioners and their deputies were directly administering the water rights in their water districts, were collecting the diversion and river-flow data and reporting to the Divi- sion Engineer. The 1969 General Assembly abolished the water districts • -2- RESOURCE CONSULTANTS INC and considered the Water Divisions the management units for water distri- • bution. This act, although eliminating the water districts, did not change the original water administration practices and each Water Commissioner is responsible for. approximately the same area as was the former water _district. Types of Water Rights -Based upon the point of diversion, the intended water use, and the sources of the water, there are different types of water rights issued by the courts characterized by significant differences in their administration. Following is a brief description of these various types of water rights and their legal and administrative characteristics. Direct-flow diversion right This water right implies an operation whereby water is diverted from a river through a ditch headgate, transported by a ditch or canal to the place of use where it is applied to the stated beneficial use. A reason- ably short delay in the application of the water is allowable, exemplified by a system that has an equalizer storage reservoir. In these cases, water is detained from a few hours to at most a few days, but not any longer. Such are the operations exercised primarily by irrigated agriculture and by municipal water users. Relating to the beneficial use of the water a few observations must be made. An appropriation that has been made for agricultural irrigation will generally consume only a portion of the water diverted for that bene- ficial use. Water losses are suffered from the ditch while carrying the water to the place of application both in the form of evaporation toward the atmosphere and to a greater extent as seepage loss to the ground water of the area. Similar losses are encountered on the farm where the water is used for irrigation in the form of evaporation, deep percolation to the ground water, and tailwater collecting at the lower end of the agricultural field. To prevent some of these losses the appropriator may line his ditch, which option is not frequently exercised due to its high cost; nevertheless, it is available to him. On the field of application the appropriator is • -3- RESOURCE CONSULTANTS INC A S Entitled to capture his own tailwater and reuse the same for irrigation • on his land. As it is commonly referred to by water administration offi- cials, the water is in the possession of the appropriator as long as he is able to keep or recapture the water in his own facilities. An open question exists concerning deep percolation from the irrigated cropland which water could be feasibly and physically recaptured by the use of shallow ground- -water wells. As it stands today, no clear-cut answer exists regarding this water in the statutes or in case law. Storage rights Sporadically, before the turn of the century and at a much more exten- sive scale shortly thereafter, water users began constructing storage reservoirs. By this time it became obvious that due to the river-flow fluctuations prevalent in this part of the country, an extension of the water supply is only possible by storing part of the plentiful spring runoff for later use in the irrigation season. It is also possible with adequate storage to carry the unused part of one year's water supply over into the next irrigation season to improve the water supply of a potentially dry year. Storage rights are generally junior to most of the significant direct- flow diversion rights and are mostly used in conjunction with the direct- flow rights. Concerning the usability of storage water there are two schools of thought advocated by water users and administrators. Apparently both are based upon earlier court decisions and it is likely that a case will try this question in the not-too-distant future. According to one theory, the owner of the storage right has an absolute control over the lawfully diverted water and can practice an operation resulting in 100 percent consumption of his storage water. The other school of thought ties the water to its historic use and in the case of a proposed new use or change in place of use, the historic consumption connected to that water may not be increased. As was indicated earlier, which philosophy will pre- vail in the future will have to be determined by either new legislation or by a Supreme Court ruling on this issue. • -4- RESOURCE CONSULTANTS INC • Diversions for storage are limited to times when there is no demand • for water by a more senior, generally direct-flow diversion, right. This generally limits the diversion for the period of mid-October through the next April at which time some direct-flow rights may call for water, and again continuing during the snowmelt runoff in May and the first part of June. To optimize water management statutes allow out-of-priority diversion for storage whereby the reservoirs storing at a higher elevation are first allowed to fill and then the reservoirs located successively lower along the stream may fill . This out-of-priority filling is conditional allowing the reservoirs to keep the water if the lower, more senior priorities could fill from the snowmelt runoff and requiring them to release the "illegally" stored water for the lower reservoirs otherwise. Keeping the water at a higher elevation significantly contributes to the _better use of the basin's water supply. Transbasin importation of water Numerous water rights have been issued outside of Water Division 1 for importation of that water into the South Platte Basin. Colorado Revised Statutues have special provisions for waters imported into the basin which laws make this water special and valuable. Since this water has not been part of the hydrologic system of the basin by nature, the importer is entitled to a 100 percent consumption of the imported water. In comparison with in-basin water rights,provided the owner has sufficient-facilities for the successive reuse of this water, the.consumption of such water may extend to--its. diverted- amount. Information received from the City of Greeley indicates that the Six Cities Windy Gap Project water would represent such a supply. Colorado-Big Thompson Project water This project is a transmountain diversion of water from the Colorado Basin to the Big Thompson Basin that is a tributary to the South Platte River. This project was completed with the cooperation of the United States Govern- ment and the water is administered by the Northern Colorado Water Conservancy District. The District boundaries incorporate significant areas in the • foothills that can physically receive project water and extend along the ,5- RESOURCE CONSULTANTS INC • irrigated portion of the lower South Platte Basin to the Colorado-Nebraska Aft state line. The direct use of project water is limited to the foothills area due to substantial transportation losses. The lower part of the Dis- trict receives project deliveries in an indirect fashion from the return flows of the applications on the higher parts of the District. For this reason it was agreed between the District and the United States that any direct use of Colorado-Big Thompson Project water will be limited to one single use without any physical reuse or legal claim for the effluent dis- regarding the common practice applicable for transbasin importations. Underground water rights A large number of water rights have been issued for ground-water diversions in the South Platte Basin both tributary and nontributary nature. The ground water is considered to be tributary if it is in active hydraulic connection to the main surface river of the basin and it is considered non- tributary if such a hydraulic connection does not exist within the state boundaries. Though few ground-water diversions existed prior to the turn of the century major well-drilling activity was initiated basin-wide during the drought period of the 1930s. A similar upswing in the well-drilling activities can be recognized again in the early 1950s when the basin exper- ienced a second drought comparable to that of the 1930s. The Water Right - Determination and Administration Act of 1969 has placed severe limitation on the well construction activities throughout the state to the point that new well construction has almost entirely been halted. The same act of 1969 has integrated the administration of all water rights including those issued on ground-water diversions. The tributary ground water connected to the stream has been included with the definition of the river; hence the differ- ence between a headgate diverting from the river and a well diverting ground water at a distance from the river is legislated to be the same in their physical effect on the river. The absurdity of this was undoubtedly felt by the lawmakers for they have created the term "plan for augmentation" that allows a ground-water user to give a physically proper consideration to the hydraulic connection between his well and the river, which would allow him • -6- RESOURCE COi`iSULTAi`ITS INC S a type of "out-of-priority diversion" provided he can remedy the injury caused by his junior diversion on senior water rights by releasing the proper quan- tity of water for the senior users. One can easily see that the involvement of a junior underground water right augmenting its injury by water diverted under some more senior water right can make the operation quite complex and can add a new type of bene- ficial use, namely, augmentation. The question of whether augmentation is a new type of use or merely the same use, though in an indirect manner, has not received a unique judicial definition. To illustrate the problem with an example--if ground water is used for agricultural irrigation and the injuries created by that ground-water diversion are augmented by a portion • of a senior water right likewise used for irrigation, the water has remained in the agricultural use; its place of application might have been changed, however, the supply of water has been increased.. Other water rights Some other water rights for which decrees have been issued by the courts -are briefly discussed here since they'may have some bearing on the present project of the City of Greeley. Nontributary, developed water. In its Shelton Farms case ruling, the Supreme Court has differentiated between salvaged and developed water. The justices held that a developed water resulting in a new water source within • the basin which has not previously been part of the hydrologic system can be claimed as a new water and a water right may be issued for same. At this point it does not appear that such type of water will have a significance in • this project. Exchanges. Exchanges of water and loaning of a water right for a definite period from one party to another is allowed by State statutes. Complicated exchanges have been developed and exercised in the general area and particu- larly in the Cache la Poudre Basin for a long period of time. Recent filings in the Water Court indicate that certain parties participating in exchanges felt it necessary to obtain a decree on these long-time practiced exchanges - in order to establish the priority of that exchange and apparently to protect the exchange from potential new exchanges by other parties. -7- RESOURCE CONSULTANTS INC P To optimize the water supply of the City and to minimize any eventual injury to other water users it is likely that in developing an operation plan for the land-treatment alternative, the City will want to develop certain exchanges primarily with agricultural water users of the area. If such is contemplated and developed, a protection of that exchange by a court decree would probably be advisable. Plans for augmentation. In the discussion of underground water rights above, plans for augmentation have been mentioned and their operation and purpose were briefly explained. The law requires that augmentation plans be filed with the Water Court, published and tried. The court decree issued on an augmentation plan will retain the court's jurisdiction in the case over a certain period of time during which applicant or any of the participants in the case may reopen the case to scrutinize the proper functioning of any element of the plan. The court decree similarly will have a priority determination for the proposed plan which may preclude any other party from using certain elements already exhausted by the first plan. Depending upon future legal research to be conducted by an attorney with special competency in water law, it may be concluded whether or not the City will require a plan for augmentation. Water Rights Fully or Partially Owned by Greeley The various waters owned by the City of Greeley are summarized in Table 1 . As this table reveals, there are different types of water owned by the City extending over almost all of the water-right types discussed above. The direct-flow diversion rights on the Cache la Poudre River are repre- sented by priorities 6 and 6-1/2 diverted at Greeley's raw water intake canal from the Cache la Poudre River above the Bellvue Filter Plant at the river gage on the Poudre designated as at the mouth of the canyon. These priorities have the amounts of 5 and 7.5 cfs, respectively. -8- RESOURCE CONSULTANTS INC • y • Table 1 Waters Fully or Partially Owned by Greeley Subtotals Z of (AF) total • Direct-Flow Diversions & Plains Reservoirs Priority Amount (AF) Cache la Poudre River 6 3620 6-1/2 5430 35246250259 7280 Reduction per W-7767 -390 Fossil Cr.

Oral communication with Mr. Darryl Alleman, Director, Water & Sewer Dept., Greeley, CO. -9- Priority numbers 35, 46, 50, and 59 are decreed to the headgate of • Greeley No. 3 Ditch for irrigation. The City of Greeley has two types of ownership in these water rights. The original ditch was constructed by Union Colony which was the owner of the four water rights stated above. At the time when the City of Greeley began to emerge as the center of the surrounding agricultural community, Union Colony deeded 3/8 of the water rights to the City of Greeley. With the remaining 5/8 of the water rights, Greeley Irrigation Company was formed with 525 original shares of water stock. From this time on the ditch was run jointly by Greeley Irrigation Company and the City of Greeley. At a later time Greeley Irrigation Company acquired 60 preferred rights in Fossil Creek Reservoir with a corresponding storage volume of 1 ,377 acre-feet. This acquisition supplemented the water available under the four direct-flow diversion rights with 2.62 acre-feet of storage water per share. The City of Greeley presently owns 21 shares of stock in the Greeley Irrigation Company which water stock was acquired by individual purchases. Speaking of terms of averages, this acquisition represents 20.8 acre-feet per share of direct-flow diversion and 2.62 acre-feet per share of reservoir water in addition to the 3/8 ownership of the original four water rights. The City of Greeley owns and operates numerous ground-water wells within the city area for the irrigation of green areas in cemeteries and parks. In Water Court case number W-7767 the City obtained a decree to operate these wells as alternate points of diversion for some of the Greeley No. 3 Ditch water right;'to the extent of 390 acre-feet per year of diver- sion. This water is therefore considered as not available from the general supply standpoint. Through stock ownership the City has water in Delta Irrigation Ditch, and 'in the Greeley-Loveland Irrigation Company, including Seven Lakes and Lake Loveland reservoir water. The present annexation policy of the City requires that developers provide water for lands they intend to annex to the City and Greeley-Loveland water is accepted for this obligation. It is therefore anticipated that the City's stock ownership in this company • will increase with time. -10- • — RESOURCE CONSULTANTS INC 1 The high mountain ditches represented by Columbine Ditch and Bob • Creek diversion are both transporting water into the Cache la Poudre Basin from the Laramie River Basin and therefore can be considered as imported water. Unfortunately, these structures have not been used to their greatest potential in the past 10 to 20 years and their rejuvenation may run into difficulties with the Wyoming versus Colorado decision 353 U.S. 953, (1957). This case apportioned the water of the Laramie River between Colorado and Wyoming and thereby limited any future developments for transmountain diver- sions in Colorado. The high mountain reservoirs owned and operated by the City of Greeley have active water rights and are being used intensively every year. These reservoirs represent a valuable asset to the City for these storage waters are available for direct diversion to the Bellvue Filter Plant, for releases to the lower reaches of the river, or for an almost unlimited number of exchanges. The Colorado-Big Thompson Project water owned by the City is a similarly important part of its water supply in which such water can directly reach the raw water treatment facilities of the City. Future Water Acquisition and Development • The City's participation in the Six Cities Windy Gap Project will result in an increasing of the City's raw water supply by 8,000 acre-feet of imported - water. In this project water collected in the upper Colorado River Basin is transported to the Eastern Slope using the Colorado-Big Thompson Project facilities for the use by six communities, including Greeley. The construction of the project is presently underway and this water is anticipated to be available parallel to the construction of the new sewer-treatment facility of the City. It is anticipated that at some future time the expansion of the City will overtake the remaining irrigated areas under the No. 3 Canal . As development progresses more and more of the corporate water stock should find its way to the City increasing its water supply ultimately to the • -11- RESOURCE CONSULTANTS INC average 18,000 acre-feet of diversion substantiated by the diversion records • of the ditch. How soon this transaction will be completed can not be esti- mated at the present time since it is a function of political and socio- economic developments. Due to similar expansion it can be anticipated that the City will increase its ownership of the Greeley-Loveland system. A similar acquisi- tion is potentially possible on lands served by Delta Irrigation Canal and in the direction of the town of Evans. How much water will be transferred to the City from these sources and the timing of the transfer can not be reliably estimated at the present time. For general planning purposes a conservative estimate of the water-supply increase from these sources can be placed between 20,000 to 30,000 acre-feet per year. Some minor storage rights, that according to our information are also owned by the City of Greeley, are also listed on Table 1 . With the excep- tion of one, these water rights are considered inactive generally due to deficiencies of the impounding structures. Relative to the total water supply of the City these water rights are minor ones; however, they may be used as trading stock with some of the larger irrigation companies. The potential for such consideration and the interest of certain potential parties to such a use of these water rights were considered as beyond the scope of this study, but such an investigation is recommended for the near future. Land Treatment for ' Renovation of Waste Water General description of the process The strengthening of the- effluent quality standards over the past 10 ►ears and the proposed stream classifications have markedly increased the treatment costsat the conventional municipal sewage effluent treatment plants. Similarly, an accidental or emergency spilling of raw sewage due to a plant failure is considered to be much more serious than in the past and may result in severe penalty assessments to the City. IP -12- RESOURCE CONSULTANTS INC • • In attempting to reduce treatment costs,facility investments, and • operation and maintenance costs, together with the elimination of the potential of an accidental or malfunction-dictated spill , new alterna- tives of waste-water treatment must be considered. During the last few years land-application treatment was not only proposed as an alter- nate treatment method but at some locations such pilot projects were actually completed and operated over a period of years. The general experience gained from these operations led to the conclusion that this type of a sewage treatment is viable and competitive with the conven- tional mechanical treatment facilities. In this treatment process after an initial grit removal the BOD content of the sewage is reduced by aeration and the rest is removed by either prolonged travel in porous media if the rapid infiltration method is used, or by the production of agricultural crops if the low-rate application process is selected. The production of crops, although considered as an additional benefit, is not the pri- mary purpose of the project which at any time remains the sewage treat- ment process itself. The application rate of the sewage is determined either by the nutrient uptake capacity of the crop or by the soil/aquifer character- istics transmitting the treated water. As a result the application rates are considered excessive from an irrigated agricultural standpoint. The excess water deep percolating from the root zone and joining the ground water is either monitored by sampling of the ground water at a downstream direction from the project,or if the ground water is inter- cepted by an open or closed drain system,at the emergence of the drainage line. If the treatment was satisfactory and the effluent quality meets the release quality standards to the given stream, the water is released; however, if any deficiencies in the cleaning process are discovered, structural means are provided to return the intercepted water for a reapplication. It is emphasized that in this section of the report primary consider- ation is given to the quantitative aspects of the treatment process with chemical , bacteriological , and virological aspects of the process discussed -13- RESOURCE CONSULTANTS INC 1f in other sections of the report. Since this section is devoted to the • water-right and augmentation aspects of the project, the limitations to the quantitative aspects should be kept in mind throughout the reading of this section. Alternative processes Originally there were three alternatives considered to be evaluated in the course of this study. The first one did not consider land applica- tion whatsoever, limiting the treatment to a conventional process at the site with treated effluent release to Crow Creek. The second alternative considered a preliminary treatment consisting of aeration and reservoir storage followed by a rapid infiltration application. The third alterna- tive considered a true land-treatment application with relatively low • application rates so that the waste-water renovation process is completed in the root zone. Concentrating on the basic differences in the water losses connected to the three alternatives, the smallest consumptive loss is connected to the first alternative. Water loss in this alternative is limited to evaporation from the aeration basins and from the reservoir. The second alternative experiences an additional evaporation loss that takes place from the area of rapid infiltration application and also includes an evapotranspiration loss from any grassy vegetation growing on the area of the application. The third alternative, which is a low-rate land-treatment application, has to consider the aeration lagoon and the storage reservoir evaporation, • the farm application evaporation losses, and the evapotranspirative con- sumptive losses related to the agricultural crop production. A quantitative determination of these losses will be discussed in detail in a later sec- tion of this report. • • -14- RESOURCE CONSULTANTS INC 7 T Site Selection • An examination of the present land use around the City of Greeley resulted in the selection of two areas for primary consideration. Both areas are about 12 to 15 miles from the City of Greeley in an easterly and southeasterly direction. Both of these areas are dry lands lying above the irrigation canals and not receiving any irrigation water. Presently irrigated areas were not considered at this stage of the study because of the individual private ownership of these lands and also because the rural population of these areas would probably oppose this type of project in their neighborhoods. The first area designated for consideration lies southeast of Kersey centered around a point roughly 7 miles south and 5 to 7 miles east of the town. It generally occupies the north half,of Township 3 and the south half of Township 4, both of Range 63 West. The second area considered lies on the north side of the South Platte River east of Crow Creek, a northern tributary of that river. It includes the part of Township 5 North, Range 63 West that lies to the north of the South Platte River and Sections 25 through 36 of Township 6 North, Range 63 West. A 1-mile strip on the west is added by including Section 36 of T6N, R64W, and Sections 1 , 12, and 13 of T5N, R64W. Both of these areas are dry rangeland with sparse grassy vegetation and aerial photographs suggest dune sands or similar wind-deposited materials, at least on part of these areas. From a hydrologic standpoint a primary consideration in the selection of the potential project area was that the return flows from the land application would be kept as high on the South Platte River as possible. Because of the multiple reuse of water in the South Platte Basin'1t was considered desirable that the project return flows will remain available to Empire Reservoir intake, Riverside Canal , and Bijou Canal diverting water from the river in the vicinity. The area selected on the south side of the South Platte River must therefore be kept west enough so that return flow from the project will join Boxelder Creek. Similarly, the area on the north side of the river can only extend to the east so far that the return flow will still join Crow Creek. -15- RESOURCE CONSULTANTS INC Considering the area south of the South Platte River we find two limit- ing factors. The irrigated agricultural land under Latham Ditch limits the project expansion to the north and the west. To the east and south there is Lost Creek Designated Basin that limits the expansion of the project in that direction. The designated basins are autonomous hydrologic units of the State, the ground water of which is. not considered tributary to the main surface drainage of the basin. Assuming that the geologic investigations leading to the creation of the designated basin are correct, there would be no ground-water return flow to the stream from any area that is included in the designated basin. From the standpoint of the project this would mean that all the water applied on such areas would be lost to the project--that loss would therefore not be limited to the crop consumed portion of the land application. An investigation of the aquifer and the existing water tables in the lower Boxelder Creek area where the return flow from the project would join that creek presented a serious restriction to the project. Boxelder Creek originates from a point lying to the southeast of Castlerock, Colorado, runs in a northerly direction to the east of Denver, and joins the South Platte River to the east of Kersey. The large watershed of the creek at • some locations has substantial alluvial aquifer with ground water maintained from storm deep percolations and, to some extent, by water imports by irri- gation canals crossing the basin. On the lower end of the basin south of Kersey the impervious bedrock formations approach the surface so that at some locations the soil mantle is limited to a depth of 3 to 4 feet. This rising bedrock formation causes the ground water of the basin, which is in a slow movement toward the north, to the surface at many locations creating serious drainage problems on these lands. In oral communication with area residents it was learned that drainage canals were constructed as early as the first part of the 1920s and the lower part of the creek channel has also been artificially relocated. Similar sources indicate that caution must be exercised in applying surface water for irrigation and water-level control by well pumping where such is possible. Field inspection of the lower Boxelder Creek area reveals numerous seeps and general high water-table conditions. • -16- RESOURCE CONSULTANTS INC 7 r Considering that the return flow from the project may be as high as • 10,000 acre-feet per year if rapid infiltration takes place, it becomes obvious that the project would cause serious damage to the existing lands requiring very extensive and costly artificial drainage. For this reason, along with the other limiting conditions stated earlier, this potential project area has been eliminated. With the elimination of the potential site south of' the South Platte River all investigative efforts were concentrated on the site north of the river south of Barnesville and east of Crow Creek. Aquifer investigations The collection of data began with the search of U. S. Geological Survey, State Engineer's office, and Water Court files. The area of data collection was extended to the entire Crow Creek aquifer below Cornish and also to the irrigated area south of Gill extending to a point toward the west where Ogilvy Ditch crosses Lone Tree Creek. The above sources yielded plenty of information for the presently irrigated farm areas; however, practically no information was found on the dry lands extending on the east side of Crow Creek. There are some old windmills in the area, but no drillers' logs have been found for these wells. If information was available on the depth of these wells, that information unfortunately could not be considered to be reliable as to the location of bedrock because it is known that in constructing livestock wells, drilling is continued to a depth at which the combined yield of all the traversed formations is adequate for the purpose of the well. Most, if not all , of these wells traverse the unconfined aquifer and intersect oridor two confined aquifers lying below the first bedrock formation. An attempt was made to locate oil , coal , or other mineral exploration holes in the area. A few of such logs have been found, however, in logging the formation, the drillers generally do not report the upper 100 to 200 feet of traversed material in enough detail for the purposes of this project. After the preliminary data collection was concluded, an estimated bedrock map was prepared by making extrapolation from the existing data and a test-hole drilling program was designed. As a first approach, the • -17- RESOURCE CONSULTANTS INC • drilling of 16 holes was planned in Sections 31 , 32, 33, 34, and 35, of T6N, • R63W, and Sections 2, 3, 4, 5, 7, 8, 9, 10, 11 , 14, 15, and 17 of T5N, R63W. The test drilling resulted in the unexpected finding that the bedrock formations,sandstone in some places and shales in others, are close to the surface, approximating closely the surface topography. The bedrock divide therefore closely coincides with the topographic divide running in a north- east to southwest direction through Sections 24, 26, 27, and 33 in T6N, R63W. Most of the test holes were drilled to the south of this divide indicating a • future return flow from these areas in a southeasterly direction rather than to Crow Creek. A seepage face was also noted running in a east-west direction approximately through Section 14, 15, 16, and 17 of T5N, R63W. The soil depths ranged between 4 and 43 feet. Due to the above-referenced seepage face, the proposed test hole in Section 14, T5N, R63W, has not been drilled. Based upon the results of the test-drilling program the conclusion was reached that the project area will have to be extended toward the north. Sections 14, 15, the non-irrigated portion of Section 16, 21 , 22, and 23 have been added to the area of investigation. It was also decided that because of the shallow soil depths found by the earlier test-drilling program, the test drilling of this area will be done by soil exploration equipment rather than by a more expensive drilling rig. This test-drilling program completed and reported in greater detail by ARIX drilled soil exploration holes in the approximate center of each 1/4 section of the sections considered. With a few exceptions the holes were drilled to the bedrock formation and these depths have been used to develop the bedrock contour map of the area enclosed as Plate 1 , and the depth-of-overburden map enclosed as Plate 2 in this report. From these maps it was concluded that interceptor drains will be required along the topographically lower end of the land application area and also probably at a certain distance higher on the slopes more or less paralleling the bottom line. These drain lines will undoubtedly increase the total cost of the project; however, it also provides a welcome operational control -18- RESOURCE CONSULTANTS INC for the land application process. A quality monitoring of the water col- • letting in these drain lines will allow an operational fine-tuning of the process and in the case of imperfect performance will limit eventual con- tamination to the application area. The second conclusion that can be drawn from the examination of the depth of overburden map is that the limited depth of the aquifer is ill- suited for the rapid infiltration treatment alternative. The target of the treatment process therefore must be the large area, low application rate, waste-water renovation method. The hydraulic conductivity of the aquifer could not be determined on the land-treatment area during the present exploration work for two reasons. The most important one is that most of the holes drilled have found very little or no water at all in the alluvial formation. Based on this information, no holes were constructed such that they would allow a test pumping and similarly no observation well network around such wells was constructed. Two aquifer tests conducted by the USGS have been found in the Crow Creek alluvium--one in the northeast corner of Section 25, T6N, R64W, and one in the southeast corner of Section 35, T6N, R64W. The hydraulic conductivity found in these locations were 5,800 and 2,900 gpd /ft2, respectively. The more conservative of these was used in later hydraulic computations relating to potential ground-water flow. Sewage Effluent Discharge The 12 million gallons per day has been defined as the design criterion of this evaluation. A review of earlier sewage effluent discharges measured at the City's treatment facility shows a high degree of uniformity over the year. The substantial summer peak observed in the treated water delivered to the City's water-supply system does not show any correlation with the sewage effluent data. This is a strong indication that the sewage collection network of the City does not drain the ground water or at least it does not receive excessive ground-water inflow during the summertime that is not present over the winter months. This is a pleasing fact, highly increasing the reliability of the preliminary design. -19- RESOURCE CONSULTANTS INC f The sewage collection lines will converge upon a collection site on • the delta area where no facilities are planned to detain the sewage for any substantial time. The transmission line connecting the delta plant with the treatment site at Crow Creek will have a relatively steady dis- charge year around, not counting, certainly fluctuations experienced within each day. The sewage then will pass over aeration basins and will be discharged into a large reservoir. This reservoir will serve as the source of the pumping plants and distribution lines conveying the water for land application. The primary sizing of the sewage storage reservoir was based on the assumption that the land-treatment application will be limited to 7 months of the year requiring an ability to store the sewage effluent over a consecutive 5-month period. This yielded a useful reservoir size of 5,500 acre-feet. This simple method of sizing the reservoir was considered suffi- cient at the depth of the present investigation; however, in the final design various operational alternatives may indicate that a larger reser- voir is more desirable, A reservoir content simulation based upon the assumptions that water will be withdrawn from the reservoir for applica- tion on the following schedule: April-939 acre-feet; May-1085 acre-feet; June-1741 acre-feet; July-2864 acre-feet; August-2869 acre-feet; September- 1911 acre-feet; and October-965 acre-feet; and the actual evaporation losses from the reservoir surface, however, with a constant surface area, shows the optimal reservoir content as 6,600 acre-feet over the continuous period of 1941 through 1966. At this time the above simulation was made only for this one set of assumptions which will have to be largely extended at the time of the final ' design of this treatment alternative. As would. be expected, highest reservoir stages are observed in April and May and the lowest in September and October. Consideration was given to the alternative of dividing the reservoir into two separate cells that would have some significant advantages. With- out touching upon benefits that may be present from the treatment-process standpoint, here only the operational benefits are considered. As soon as one cell of the reservoir is emptied, provided that quality considerations -20- RESOURCE CONSULTANTS INC do not negate such, return-flow water from the drains can be placed into this part of the reservoir for future releases at a time when it is bene- • ficial to the river and to other water users. This type of an operation will be discussed in greater detail in a later section of the report deal- ing with augmentation. Land-Treatment Operation A pumping plant and a distribution line network will transport the water under sufficient pressure to the individual center-pivot sprinklers for land application. Sufficient valving will be provided for each sprinkler to allow the individual operation of each unit. In reality this will translate to the simultaneous operation of certain sprinkler units which combination can then take on various configurations. Due to the different soil depths and the different hydraulic characteristics of the various soils(that probably will turn out to be even more variable with the substantially more detailed information required by the final design than what is known at the present time from the 1/2-mile spaced observation holes) the variability of the application rate is very important. From the standpoint of erosion control and limiting wind action to prevent aerosol travel from the area, protective wind breaks will be designed and similar brushy, woody vegetation will be grown in the corner areas, not covered by the center-pivot sprinklers. To irrigate these areas, transmission lines and fixed sprinklers will be installed. This would allow similarly variable water-application rates for these different vegetated areas. - ___ The application scheduling will probably have to be modified numerous times before a final satisfactory schedule is achieved. Limiting factors are the soil intake capacities and the aquifer's ability to transport water in a horizontal direction toward the interceptor drain lines. At the same time attention must be given to the erodability of the surface soils with the particular farming technique and crop cover selected as well as to the crop attendance activities. It appears that there will be water application in the pre-planting and in the post-harvest period with suffi- cient interruptions before planting, cultivation activities, and the pre- 0 harvest drying of the crop. -21- RESOURCE CONSULTANTS INC Through the continuous monitoring of the drain effluent both quantitative and qualitative observations will either verify the assumed hydraulic char- • ` acteristics and nutrient uptakes or will suggest the necessary adjustments in the operations. Water Losses of the Land-Treatment Alternative At various points on the project there will be water losses that have to be considered in the overall design. Losses here are considered water escaping the system to the atmosphere by evaporation and do not extend to evapotranspiration of agricultural crops, water becoming fixed into plant tissues or fruits, or water deep percolating from the root zone,, Evaporation losses will be encountered from the free-water surfaces of the aeration ponds and of the storage reservoir. A similar evaporation loss will be realized at the sprinkler application of the effluent to the agricultural crops. If the treated return flow from the drain lines is stored in a reservoir for timed releases to the river, a similar open surface evaporation loss will be realized from this reservoir. Lake evaporations have been estimated by using a similarity to the consumption of pasture grass in the Greeley area from 1931 through 1978 on a monthly basis. This estimation relied on the Modified Blaney-Criddle Method described in greater detail in Appendix A relative to consumptive- use estimates of likely crops on the project area. The estimated monthly lake evaporations for that period are given in Table 2. The table shows the highest variability ,in the months of April and May; however, later in the season the variations are substantial enough for consideration in the water-balance computatio n. Similarly the evapotranspiration losses of different crops that will be considered for the project were estimated by the Modified Blaney-Criddle Method and are included in Appendix A of this report.

For the purposes of some of the calculations a 10 percent loss was assumed and for other computations an assumption of 20 percent was made in each case so that the computation would be optimized in the more critical or conservative direction. In the final design of the project specific recommendations will be made for the accurate measurement of the losses and generally a balance accounting for each sub-unit of.the project wherever such is practical . Land Application of Sewage and Project Return Flows In determining the application depths on the land application area the deciding parameter is the physical and hydraulic characteristics of the porous media. The test-drilling program revealed a relatively limited porous material mantle deposited over impervious formations that acts as a limiting factor for the annual application. Based upon the overburden depth map and on the bedrock contour map the land was divided into parcels using the assumption that within each parcel the thickness of the porous material and the slope of the bedrock can be assumed as uniform. Selecting an arbitrary drain spacing assuming that the drain will act as an interceptor line, the application depth was deter- . mined on the basis of computing the porous media flow through the given parcel or combination of parcels. The hydraulic conductivity of the porous material was assumed to be 400 feet per day taken from the more conservative pumping test result of the USGS. In this calculation it was assumed that the lowest drain line is placed on the bedrock formation so that a complete interception of the flow takes place and any other parallel higher-lying drain lines are laid at a constant depth sometimes above the bedrock. In places where the drain line was above the bedrock, the unintercepted flow was assumed to collect in the lower drain line,in some cases limiting the application potentials on the lower parcel . • -24- RESOURCE CONSULTANTS INC • • The assumed characteristics of the parcels are summarized in Table 3. • In considering the quantities shown in Table 3 and throughout this entire section it must be kept in mind that aquifer thicknesses were obtained at a grid with data-point spacings of 1/2 mile and also that no actual determination of the hydraulic conductivity of the material could be done. Due to the preliminary nature of the field investigations and surveys local seepy conditions are anticipated and those areas will require indi- -Vidual attention and drainage by relatively short drainage lines. In determining the application depths a sprinkler-to-soil application loss of 10 percent was assumed which in actuality is rather optimistic, however it results in a greater deep percolation rate and hence keeps the • computations on the more conservative side. Two alternatives were considered for the farm layout--one with a main drain-line spacing of 4,000 feet and the second with a main drain-line spacing of 3,000 feet. In the first alternative it was assumed that the crop is grain corn, the root zone that is the non-saturated top-soil layer is 5 foot deep, and the drain lines are laid at a depth of 12 feet. This alternative is shown on Plate 3 and the computed application rates are shown in Table 4. The second alternative has a drain spacing of 3,000 feet laid at a depth of 10 feet,and in various modifications different crops and different root-zone thicknesses have been assumed. In Modification la, the crop was alfalfa and the root zone was considered to be 5 feet. In Modification lc, the crop was corn and the root zone was similarly 5 feet. Modifications 2a and 2c have a root zone of 3 feet and an irrigated crop of alfalfa and corn, respectively. A graphical presentation of Alternative 2 is enclosed as Plate 4 with the application depth computations shown in Tables 5 through 8 for the four modifications. These tables show the parcels included in each modification that can then be identified with the parcels designated on Plate 4. In each alternative and modification the total annual applica- tion approximates 12,000 acre-feet which is the quantity that will reach the land-disposal site after evaporation losses are deducted. The return- flow quantities to the drain will vary between alternatives and modifications ID -25- RESOURCE CONSULTANTS INC Table 3 • Pervious Overburden Thickness and Slope of Bedrock or Impervious Layer for the Different Uniform Depth and Constant Slope Areas in the Land-Treatment Application Alternatives 1 and 2 Pervious Bedrock or overburden impervious Parcel thickness layer slope (ft) (ft/ft) A 14 20/1250 B 6 20/2250 C 5 w D 14 20/2800 E • 9 20/900 F 18 20/1500 G 12 20/2000 H 19 2O/1200 I 9 20/1200 J 11 20/1400 K 4 --- L 14 20/1400 M 20 20/1800 N 16 20/1500 O 9 20/900 P 3 • -,26- RESOURCE CONSULTANTS INC • - R ^ 'O a) .

The steady-state drain interceptions based upon average-year conditions are shown in Tables 9 through 13 for each alternative and modification. In the design of the drain lines consideration must be given to the fact that these flows were computed using average conditions that will be exceeded in wet years and further that particularly the lower line will also receive ground-water inflow from the west side. This inflow will depend upon surface-water importation to the presently irrigated areas and also upon the operation of the existing irrigation wells. At the time of the final design of the drain lines sufficient aquifer data must be collected for the hydraulic computations required to answer these questions. Similarly, a method of operation of the land-disposal process must be defined in great detail . To demonstrate the importance of the operation scheduling, two examples can be considered. The first one is a fixed application schedule in which for each week of the application season a fixed application rate is prescribed. A second operation schedule could be made dependent upon precipitation and temperature measurements at the site with an expressed tendency to stabilize the rate of overapplication at any time during the 7-month application period. It was implied earlier that a precise computation of the return flow from the project as a function of time cannot be performed at the present time. The computations required to develop the return-flow function is not only very complex but also sensitive to variations in the data. The pre- sently available data are quite limited and in no way warrant the invest- ment of time and resources needed for these computations. It is fully realized that this information is essential for the development of the detailed augmentation plan, which will be discussed in greater detail later; however, at this stage of the design other different aspects of such a plan are similarly ill-defined.

The modeling was extended to both alternatives and the four modifications of the second alternative for comparison purposes. A fixed operation policy was assumed through the 26-year period with a identical application depth for each year. The monthly application depths were determined by parcels based upon the aquifer water-transmitting ability and the average irrigation requirement of the particular crop. To keep the computation on the conservative side from a return-flow standpoint a 20 percent sprinkler-to-soil evaporation loss was assumed. In these model runs the return flows were obtained by subtracting the actual crop consumption from the water entering the root zone. The simulated deep percolations for each alternative and modification are shown in Tables 14 through 18. The statistical footing of these tables give some indication on the variation of the data that results from the fixed application schedule. Simulations with different operating assumptions have not been run at this time; however, numerous such modelings are anticipated during the course of the final design of the project. The results of these modelings will be used as the basic data in modeling the porous-media flow to deter- mine the timing of the return flow. As was mentioned earlier, due to lack of sufficient data, this step has not been executed at this time. The present layouts of the alternatives were selected such that all of the project return flows will remain in the Crow Creek Basin and releases of renovated water from a reservoir or from the drains will be made to the surface channel of Crow Creek. • -48- RESOURCE CONSULTANTS INC • Table 14 • • Alternative #1 1/ Flows Available for Deep Percolation/ (Ac-ft) Year Jan.

"Plan for augmentation" means a detailed program to increase the supply of water available for beneficial use in a divi- sion or portion thereof by the development of new or alter- nate means or points of diversion, by a pooling of water resources, by water exchange projects, by providing sub- stitute supplies of water, by the development of new sources of water, or by any other appropriate means. "Plans for augmentation" does not include the salvage of tributary waters by the eradication of phreatophytes, nor does it include the use of tributary water collected from land surfaces which have been made impermeable, thereby increasing the runoff but not adding to the exist- ing supply of tributary water. Plans for augmentation are generally used by ground-water wells with relatively junior priorities but without physical limitations on their diversions. Beyond this type of plan one can be designed to protect the rights of other water users from activities that would illegally injure their established rights. Mere -depletion of the stream is only considered an injury if there is at least one senior water right with a valid demand for water that is deprived from all or part of its water by the depletive effect of the junior right. It is emphasized that the senior water right is only entitled • to make a valid call for its water entitlement at times when he has definite need for that water and he is putting the water to beneficial use. Simi- larly he is only entitled to an amount of water that he is able to put to beneficial use at the time of registering his demand. At times of such valid senior demands the augmentor must release an amount of water equaling its depletive effect at that given time provided such water would reach the headgate of and become physically usable for the caller. If the released water is not physically available to the calling party the call is considered a futile one for that particular junior water right that caused the depletion effect. -54- RESOURCE CONSULTANTS INC • • ... •x Is a plan for augmentation required? • The use of the water diverted under the water rights owned by the City of Greeley is municipal . A municipal water use after the diversion of that water requires a preliminary tr.eatment,generally filtering and chlorin- ation,prior to introduction into the municipal water-distribution system. The distribution system provides water for the households for both of their in-house and external uses. The external water uses--lawn and small garden irrigation, car washing, etc.--will generally not enter any type of sewage-disposal system, but whatever portion of this application is not consumed will deep percolate or enter a flood drainage system if such exists. The in-house uses limited to kitchen, bathroom, and washroom uses, will generally consume less than 10 percent of the original supply and the effluent will end up in some type of a sewage-treatment system. Sewage treatment has undergone significant changes with time and it is still in a transient state today. In early days individual septic systems treated the effluent and disposed of the water either by infil- tration or by evaporation. The former unintentionally recharged the ground water of the area and did not lose the water while the latter must be con- sidered 100 percent consumptive. With the development of the sewage-treatment technologies and undoubtedly with the increase of the densely populated areas, the sewage collection system and the central sewage-treatment facility become the common practice. These central sewage-treatment facilities have a very limited evaporative loss and return= the water to. a surface-water course. Smaller communities, even today, operate evaporative types of central sewage-treatment facilities. Consumption, therefore, from one community to another and from one time to another in the same community, may show extremely large variations. During the past decade social forces have strengthened the effluent standards for sewage-treatment plants immensely, a stream quality classifi- cation system has been proposed based upon quality requirements,and stan- dards are being developed for non-point-source agricultural return flow qualities. These developments require the significant upgrading of existing • -55- RESOURCE CONSULTANTS INC • sewage-treatment facilities and in numerous cases necessitates the construc- • tion of entirely new treatment systems. A few years ago technology realized that in satisfying the stringent effluent quality standards, a number of constituents have to be removed from the municipal sewage that is immediately placed back into the water by the agricultural community if the effluent is picked up for such uses. This realization led to investigations of cleaning the sewage by the bio- logically natural method, namely, by applying it to agricultural crops. In this system sewage renovation is achieved by the bacteriological action of the root zone and by the plant uptake of nutrients. In this method, by achieving the main objective of rejuvenating the sewage, an additional benefit, agricultural production is realized. Nutrient uptake by agricultural crops is always coupled with water uptake since the nutrients must be in a water soluble form for the absorp- tion by the root system. Similarly, the healthy growth resulting from the nutrient uptake will result in more water being built into the plants and circulated through them by sap flow and evapotranspiration. This new sewage renovating method is therefore more water consumptive than a mechan- ical sewage treatment plant. From the above discussion it might well have been the truth that the consumptiveness of the sewage-treatment process has undergone numerous changes in the past. At the same time probably nobody will dispute the fact that the use of water under a municipal water right is not limited only to in-house or external consumption by the residences and businesses, but also includes any loss connected to the chemical and biological treat- ment of the effluent. The higher standards of sewage effluent treatment imposed- by society raises -the question whether the same society intends to further penalize the City by requiring replacement for the water consumed in the higher level treatment process. It is not known whether this ques- tion has been raised, neither is there any indication that this question was answered by the legislators or by the courts. For the further inves- tigation of this point the City must enlist the services of an attorney 'who, preferably, is familiar with water law. • -56- RESOURCE CONSULTANTS INC • Elements of an augmentation plan • Assuming that the City will have to augment for any additional consump- tion of its sewage effluent in the amount of the illegal depletions, the injured water rights, and the method and place of augmentation releases -must be determined. Considering the sources of waters introduced into the City's system, depletions of in-basin diverted water and that of Colorado- Big Thompson Project water must be compensated for. As it was explained earlier, water imported by the City into the South Platte Basin can be completely consumed or the proportionate part of the effluent claimed for replacement purposes. At the present time the City has only very limited ownership of such waters; however, after completion of the Windy Gap pro- ject, this type of water will become significant. The question as to whether replacement has to be provided for waters originating from the City's reservoirs cannot be specifically answered at this time. It was mentioned earlier that there are different legal theories concerning the reservoir water and if the City chooses to claim 100 percent of its reser- voir waters, the question will probably have to be decided in court. To answer this question the City will have to enlist the services of legal counsel with sufficient experience in water law. After it is determined which of the City's water types require aug- mentation, the magnitude of the augmentation requirement at any day is relatively easy to determine from the filter plant's records. Since the City does not have substantial internal storage facilities that could change the timing of the return flow by an appreciable amount, an assumption of almost immediate effluent appears to be sufficiently correct. It is simi- larly reasonable to assume that within the City water-supply system, the different types of water undergo a complete mixing so that a proportioning based upon the sources is sufficiently accurate. Determination of the injured water rights. If the river depletions resulting from the land-treatment of the sewage effluent are considered illegal depletions,there are two types of injuries to be considered. In the first one, the City is changing the point of effluent return to the stream and in the second there is a water consumption connected to the • treatment process. -57- RESOURCE CONSULTANTS INC Treated sewage effluent released from the City into the Cache la Poudre • is physically available to Ogilvy Ditch and to Hoover Ditch. Considering that the new point of return will be through Crow Creek there are no other headgates between the old and the new points of return requiring this con- sideration. Irrigators under the Hoover Ditch have decreed their shallow ground- water wells as alternate points of diversion to the direct-flow diversion right of the ditch. Apparently from an operational standpoint there are practically no diversions from the river by that ditch and the water supply is obtained instead from ground water. From this arrangement it appears that the proposed change of the effluent point of the treated sewage will not injure these water rights. Unfortunately the same statement is not true for Ogilvy Ditch. The ditch has a certain physical reliance on the treated effluent that will have to be compensated for. The real question is the determination of the magnitude of the injury which question is somewhat complicated as explained in detail below. A direct-flow water right is entitled to place a call on the river for water when water is needed for beneficial use and the water is not avail- able in the river at the headgate of the ditch. At the same time, the water right must be in priority; that is, there may be no call on the river by any more senior water;right. The amount of water for which a call may be made is certainly limited by the amount of the water right itself. On November 4, 1893, the City adopted Ordinance No. 70. Subject to ' numerous provisions in this ordinance the City has granted the right to use part of its sewage effluent to a W. Albrecht Insinger. A 24-inch diameter conduit was to be constructed by said Insinger to transport the water from the City's collection point across the Cache la Poudre for use of the effluent on the north side of the river. The grade of said conduit was specified as 1 foot/1 ,000 feet. The estimated capacity of the conduit, assuming gravity flow, was somewhat above 8 cfs. The ordinance allowed Insinger to use the water for irrigation or to release the water to the Cache la Poudre River as he wished. Ordinance No. 70 grants the i -58- RESOURCE CONSULTANTS INC , f Use of effluent waters to Insinger, his heirs and assigns. It is not known • at the present time whether Ogilvy Ditch Company can be considered legally the assign of the original grantee. Assuming that the grantee is Ogilvy Ditch Company, there is the question as to whether an agreement between two parties can override the administra- . tion of the priority system. Valid appearing arguments can be made for either side and this question has to be answered by legal counsel or possi- bly by the courts. If the conduit required by Ordinance No. 70 is still in existence a flow measurement in the conduit can be arranged to establish the upper • limit of the amount that could have been the subject of the ordinance. To estimate the amount of sewage effluent that could have been picked up by Ogilvy Ditch under the priority system, the historic ditch diversion, the historic City of Greeley sewage effluent releases, and the river-flow records in the Cache la Poudre River near Greeley have been collected and analyzed on a daily basis. The river-gaging station is about 1 .8 river miles downstream below the headgate of Ogilvy Ditch. Therefore, on this short stretch of the river only a limited amount of underground return flow or river gain can be expected. The amount of this river gain was assumed to be 7 cfs; that is quite high but would keep the results of the modeling on the conservative side. • It was considered that the "river" at the headgate of Ogilvy Ditch consists of the natural river flow and the total sewage effluent released by the City. To allow for the return flow between the ditch headgate and the gage it was assumed that if the flow in the river at the gaging station is 7 cfs or less, Ogilvy Ditch has diverted the entire flow of the river at its headgate. Any river flow at the gage exceeding 7 cfs was considered to be available at the ditch headgate that the ditch has not diverted apparently in lack of need. This quantity then was deducted from the sewage effluent of the City and considered as releases not required by the Ogilvy water right. Subsequently, the daily sewage effluents that were diverted by Ogilvy Ditch were summarized to arrive at the seasonal totals. During • the last 5 years Ogilvy Ditch has obtained the following quantities from • . -59- RESOURCE CONSULTANTS INC sewage returns: 1974 - 129 acre-feet; 1975 - 118 acre-feet; 1976 - 59 acre- , feet; 1977 - 873 acre-feet, and 1978 - 6 acre-feet. These quantities have been made available to Ogilvy Ditch from the City of Greeley's sewage returns. The data show a quite variable water availability pattern, and at the time of designing and operating the final augmentation plan, a daily accounting will be required throughout the irrigation season. Augmentation releases for Ogilvy Ditch can be made either through the Cache la Poudre River from sources above the headgate of the ditch or since the irrigated area of the ditch is between Lone Tree Creek and Crow Creek, treated water could be piped back from the treatment site directly into the ditch. Injury to other water rights can be alleviated by releases through Crow Creek or at any point higher on the river. Similarly, any return-flow credit from the land-application treatment process will discharge into the river via Crow Creek. Historic calls. Calls by senior water rights for water that would have affected the City of Greeley if the land-application treatment had been implemented in the past is evaluated on a 26-year period of call 'records from 1941 through 1966. Table 19 shows the number of days in each month of the above period on which days a senior water right was demanding water pertinent to the augmentation plan of the City. Due to the lack of sufficient data a quantitative evaluation of the augmentation requirement was not attempted at the present time. Similarly, in some cases legal interpretations need to be made in order to define the project depletions themselves. Some of these questions may require trying them in the court, which process could be quite lengthy and certainly will extend over the deadline of this evaluation. Table 19 is included to give some indication of the call frequencies and distributions that serve as a helpful tool in the selection and the design of the final treatment alternative. The timing of the return flow can be accelerated with the installation of additional drains and a separate storage facility for the treated water may be necessary from a water-saving standpoint. These and similar facilities together with the III -60- RESOURCE CONSULTANTS INC Table 19 • Historic Calls Which Would Have Required Augmentation Number of Days with Senior Calls for Water Year Jan, Feb.

Sources of augmentation water. The water rights presently owned by the City were shown in an earlier table in this report. Out of those, the water rights belonging to No. 3 Canal cannot be physically used in the water-supply network of the City; therefore they will be considered pri- marily for augmentation purposes. • The future growth of the City will undoubtedly result in the acquisi- tion of additional agricultural water rights in the form of direct-flow diversion and storage rights. These will likely originate from areas around the City and most of them will not be suitable for treatment and direct use. Water obtained from the Windy Gap project presently under construction represents a significant quantity of valuable augmentation water. At the time the Windy Gap project is completed and the No. 3 Canal is fully acquired, only from these sources an estimated 8,000 to 10,000 acre-feet will become available for augmentation. A part of the high mountain reservoirs that represent almost 25 percent of the present supply could immediately become available for augmentation. It is anticipated that this water will be used through exchanges in the augmentation plan rather than by direct releases to the river due to the high transportation losses. With the existing supply and the projected acquisitions it appears that the City has ample water to meet its eventual augmentation requirements. The composition of the types of water rights is also fortunate and allows a large degree of operational flexibility in designing the augmentation plan. • -62- RESOURCE CONSULTANTS INC • APPENDIX TO WATER RIGHTS • • CROP-WATER REQUIREMENT AT THE LAND DISPOSAL SITE Resource Consultants, Inc.

It influences significantly the farm design, the crop selection, the nutrient-disposal capacity of the project, the magnitude of the incidental artificial recharge, and ultimately it is the kernel of the plan for augmentation. An analysis of the crop-water requirement at the proposed land-disposal site is presented in this report for the crops that may be fully or partially relevant to the contemplated project. Definitions Before explaining the analysis itself, certain terms that will be used later on must be defined, The following definitions are reproduced from the "Consumptive Use of Water and Irrigation Water Requirements," a report pre- pared by the Technical Committee on Irrigation Water Requirements of the Irrigation and Drainage Division of the American Society of Civil Engineers, edited by Marvin E. Jensen, September 1973. Consumptive use is the total amount of water taken up by vegetation for transpiration or building of plant tissue, plus the unavoidable evapor- ation of soil moisture, snow, and intercepted precipitation associated with vegetal growth. Deep percolation is the drainage of soil water by gravity below the maximum effective depth of the root zone. Effective precipitation is that portion of precipitation which remains on the foliage or in the soil that is available for evapotranspiration, and which reduces the withdrawal of soil water by a like amount. Evapotranspiration is the combined processes by which water is trans- ferred from the earth surface to the atmosphere: evaporation of liquid or solid water plus transpiration from plants. • -1- RESOURCE CONSULTANTS INC • Irrigation efficiency is the ratio of the volume of water required for a specific beneficial use as compared to the volume of water delivered • for this purpose. - Irrigation water requirement is the quantity of water exclusive of precipitation that is required for various beneficial uses. Soil water is the water present in the soil pores (also called soil -moisture which includes water vapor). Method of computation Using the above definitions, the following monthly quantities have been computed for the pertinent crops: (1) Consumptive use (2) Effective precipitation - (3) Irrigation water requirement _ - These quantities were estimated by the Modified Blaney-Criddle Method as presented in the publication, "Irrigation Water Requirements," Technical Release No. 21 (Rev. 2), September 1970, U. S. Department of Agriculture, Soil Conservation Service, Engineering Division. This method has been widely used and extensively evaluated, among others, by the above quoted Technical Committee of the Irrigation and Drainage Division of the American Society of Civil Engineers, with excellent results, and similarly the method is known to and repeatedly accepted by the courts. The Modified Blaney-Criddle Method estimates the crop-water consumption by two basic components of the evapotranspiration process. The driving force of the process tMt provides the energy necessary for evaporation is represented by the recorded temperature and by the potential duration of sunshine over the selected time period. The ability of the plant to tran- spire water is represented by a coefficient describing the growth stage of the crop at any time within the growing cycle. The above energy parameters are either commonly measured and recorded quantities (average daily, weekly, or monthly temperatures) or can be com- puted from simple global geometry (potential sunshine duration) . The potential cloud cover, a significant modifier of the energy representation, • is included only in an implied manner through its manifestation by the tem- perature. -2- RESOURCE CONSULTANTS INC It is noted that other methods available for estimating crop-water • consumption rely on other parameters (like radiation measurements) ; however, such parameters are not commonly measured at numerous locations over a longer period of time. In comparison those methods do not show a signifi- cantly improved estimate, hence, were not considered in the present study. Data used and period of analysis The crops considered in this analysis were: .(1) Silage corn (2) Grain corn (3) Pasture grass (4) Alfalfa (5)• Orchards with cover (6) Orchards without cover The consumptive use, effective precipitation, and the irrigation require- ment were estimated for the calendar months of the growing season. The climatological data used for these computations, namely, frost dates, mean monthly temperatures, and total monthly precipitation figures, were those collected and published by the U. S. Weather Bureau for the Greeley observation station. The analysis was carried out over the continuous period of January 1931 through December 1978. This study period is significant in that it includes two considerably dry cycles that were experienced during the early 1930s and the second over the years of 1952-56. Analysis results The results of the 'analysis are included in this report in tabular form for each of the crops analyzed. On the bottom of each table, arith- metic averages and standard deviations are shown to provide some statistical evaluation of the quantities. Further, statistical information is obtained from the "ordered array" representation of the results, key quantities of which are summarized in the statistical summary table, also included in the Appendix. • -3- RESOURCE CONSULTANTS INC • • • I Interpretation and use of the results • IDThe design of the farming operation and/or the rapid infiltration basin, that may have a pasture-grass type vegetation cover, must consider the water losses connected to every alternative studied. The time, loca- tion, and magnitude of the water consumption are basic parameters in the augmentation plan to be developed for the given alternative. From the standpoint of farm design, each "standard acre" will have a crop composition, and a related water consumption, including the major crop, crops to be used in an eventual rotation, and the shrubby/woody vegetation used for windbreaks, wildlife habitat, or aesthetic purposes. The data supplied in this report will enable the farm designer to deter- mine the water requirement of raising a healthy crop; on the average, the highest monthly requirement within an average year- or the highest summer sequence on record. In considering nutrient loading and consumption, the record of low irrigation requirements is to be considered because providing the same application to the farm area will obviously result in a greater deep per- colation and a limited nutrient takeup by the plants. Simultaneously considering the effective precipitation received during such periods, information is gained about whether the low irrigation requirement resulted from an above-average precipitation, or from below-average temperatures which would represent a truly lower demand. The irrigated farming operation will rely on a dual water source represented by the waste-water effluent rate received from the City at any given time and by water stored on the treatment site. In sizing the storage reservoirs, one important factor is meeting the crop-water requirement, and any intentional overapplication for ground-water recharge, by the optimal reliance on the two water sources. Again, at this point the impor- tance of relying on sequences that have historically occurred and are por- trayed by the enclosed tables can not be emphasized enough. • -4- RESOURCE CONSULTANTS INC Table 1 (a) SILAGE CORN - CONSUMPTIVE USE (in.)

Thinks the approach practical and desirable. Thinking in terms of perhaps future service for Kersey. Freda Klein - Concerned about the effect of flow return to South Platte and effect on underground water supply in the area. Travelers Insurance Co. , Real Estate Dept. - Ranch is in process of being sold. Did not want to reveal potential purchaser or have them contacted (70 ranch). 4/16/79 Jim Parks - Return water to river by percolation or direct return. Do not break out any more sandhill grass. Stow Witwer - Busy in field. Set up appointment for Tuesday afternoon. Jack Wells - Jack was attending Ditch Board meeting. 4/17/79 Rex Davis - Generally agreed with the intent of the project and offered to help in getting a group of farm people that might be affected together for a discussion. Buster Peterson - Thought the return of the effluent to the river was a good idea, but didn't think it would effect him. He directed me to his sister-in- law's place, but no one was home. Stow Witwer, Sr. - He seemed to favor returning the treated water to the river via Crow Creek, but expressed some interest in injecting it back into the aquifer. He doesn't think land application is practical to grow crops or to apply to native grasses. He flatly states that he will fight any attempt to locate any portion of the project on land he now controls. 4/19/79 Jack Holman - Believes the lagoon treatment and land application is more sensible than the Delta Treatment Plant. He is concerned about the effect of project on water rights of Oglivy. Matter is going to have to be dealt with in a satisfactory manner before any options can become a reality. Bill Pritchard - Not concerned about the project as it is probably far enough away from him to not have any direct affect. Jack & Lillian Wells - Position open at this time. He doubts the economic feasibility, of the sprinkler application for corn production. He flatly states that there must be some economic incentive for him to be involved. 1 • Harvey Peppler & Wife - Concerned about the proximity of any lagoon facility to their operation. They do not see any benefit to be derived from the project and the possibility of something undesirable in the area. They feel that any additional water for irrigation should be put to use for growing crops. 4/20/79 Ed Meyer - Emphatically supports the application of water to new land if the water rights issue can be taken care of. Is doubtful about putting the effluent back in the aquafier because it might pollute the wells. Not too concerned about the location of such a facility in the area as long as it was not up-wind and too close by. Frank Mondt & Wife - Mrs. Mondt is opposed to any and all aspects of the proposed project. Frank is not opposed to the concept of applying the ef- fluent to the production of crops. Concerned about the possibility of con- taminating underground water supply if treated sewage water is injected back into the ground. Ralph Lohr - Apprehensive about discharging effluent into Crow Creek for return to the South Platte River. Crow Creek runs through the corner of their farm and is source of water for livestock pastured there. Prefers sprinkler land application, if water rights problems can be worked out. 4/23/79 Jacob Miller, Jr. - Concerned about the possibility of a lagoon being located near his farm. He has a drainage easement across State Section 6 (Witwer lease) to Crow Creek for his waste water. His preliminary conclusion was that the best thing for him to do would be to sell his entire 320 acres to the City of Greeley for a big price and get out of the area. John & Carl Nakagawa - John is interested in the effect total land application would have on Ogilvy Ditch rights. He states that effluent from the present plant constitute 30% of Ogilvy's late water supply. Sees no problem in dumping effluent in Crow Creek which runs through his yard. Rich Peterson - (Son of Vera Peterson, landowner) Is interested in land application aspect of the project. His mother owns land in an area that might be feasible to put under sprinkler. McKelvy - Interested in the possibility of acquiring some water rights on Crow Creek for his land which has only wells for irrigation. 4/24/79 Duane Flack - Very receptive to the concept of crop land application. He advised me that Monforts are doing a study on the effect of feedlots to quality of well water in the area around the feedlot. He said Monfort would • cooperate in any way they could. The subject of opening County Road #61 through the Witwer property south the Kuner was brought up. Several other property owners mentioned this also. This may be of concern to the City of Greeley if a large installation is made in the study area. • 4/26/79 Rienhold Wacker - First concern was the effect this project might have on Ogilvy ditch rights. He liked the farm land application option and expressed concern about polluting the underground water. Jack Larson, Don Vornholt - Both busy today. Mrs. Victor Wolfe - Not receptive to any part of the project. Will talk to Victor Wolfe later - is busy getting crop in. 4/27/79 Vera Peterson - Interested in any proposal that might increase financial return to her ranch. Don Vornholt of Davis Agency - Vornholt said he didn 't think it would affect them. Non-committal about option preferred as to disposal of effluent. 4/30/79 Windolph - Conference on project and upcoming report. 5/3/79 Council Chambers at City Complex - Windolph presentation to Sewer and Water Board. 5/10/79 Jake Miller, Jack Wells - Darryl and I drove to Jake Miller 's and discussed project with Jake and his wife. Drove on to Well 's and talked with Jack and wife. 5/15/79 Stow Witwer, Sr. - Drove to Witwer Ranch and visited with Witwer about the job. 5/17/79 Millard Bashor - Said they might be able to use some of the water on the sprinkler land west of Jake Miller Farm. Bruce Wells - Not at home. 5/25/79 Jack Miller, Stow Witwer Sr. , Wells - Called for and received permission to run levels on SLW and Miller land and Well 's Ranch. • 6/7/79 • Jack Wells, George Palos, Stow Witwer, State Land Board - George Palos con- tacted me to get permission to drill test holes on Wells, SLW and State land. I called State Land Board about permits. Called Jack and made appointment for Monday, June 11. Drove to Witwer's and located sites in pasture. 6/11/79 Jack and Bruce Wells, George Palos - Met Bruce Wells at Jack 's house. Bruce and I located and staked 12 locations for test drilling. Called George Palos and told him we were ready to go on test wells. 6/14/79 George Palos - Palos called and wanted to add more test well locations on S.L.W. and Mrs. Peterson' s. Peterson - Called Peterson for Monday appointment. 6/15/79 Jake Miller - Drove out to see Jake Miller to get permission to drill some soil test borings which he approved. Jack Larson - Talked to Jack about the project. Was not very receptive and didn't think it would benefit him. Bud Straight - Concerned about a possible effect on #3 ditch water. Would like to see a sewer and water line near his place. 6/18/79 George Palos - Palos called and said we were set-up to start drilling. Sam Rank - Rank called to confirm drilling schedule. 6/26/79 Drove to Well 's Ranch to find Hartman who was running absorption tests. 6/27/79 Palos, Windolf, Alleman, Kelly - Conference on waste water project at ARIX office. 7/9/79 Kenny Harsh - Concerned about future to #3 water right. 7/11/79 • Kelly, Steichen - Met Kelly and Steichen in field and looked at possible routing from 1st Avenue plant to Delta site. 6 • 7/12/79 Paul Hashiko - Is receptive to project. Talked about forming Conservancy District to build Narrows Dam. 7/17/79 Millard Bashor - Are definitely interested if they can apply it on land as they are short of irrigation water. Carol Bishop - Interested in the possibility of getting some water from the project to develop the S/2 of his 1/2 section. Cecil Osborne - Telephone conversation. Offered to take effluent in Riverside Reservoir. 7/18/79 Elmer, Harry, Manuel Rothe - Met brothers at their headquarters north of Wiggins. They are very familiar with the project as Elmer has contact with Darryl Alleman and W.D. Farr. They spoke of the possibility of getting the effluent to the Riverside Reservoir. Mr. & Mrs. Lee A. Miller - Courteous, but not receptive, especially Mrs. Miller. Had discussion about the project and they complained about not being kept up-to-date on the project. • • APPENDIX D DESIGN CRITERIA • OUTFALL SYSTEM NORTH LINE-GRAVITY A. Design Criteria 1.

Control Division • FROM: Frank J. Rozich • • DATE: Maceh 18, 1977 . - SUBJECT: Interim Division guidance on planning and design review—for land • application systems. • The following interim division guidance concerning review of planning documents and designs for land application systems is effective immediately. • Because wastewater treatment is of concern, both from the public health and environmental quality standpoints, review of land application systems will con- sider the degree of pretreatment, potential effects on groundwater, potential for nuisance development and utilization of water and nutrients. • INVESTIGATIONS • • In general , the following EPA publications should be used in evaluating land application systems: a. Evaluation of Land Application Systems, Technical Bulletin No. 430/9-75-001 , March -19, 1975. b. Wastewater Treatment and Reuse by Land Application, EPA Technology • -Series No. 660/2-73-006 A and B, Volumes One and Two, August, 1973. : To be more specific, investigations must include but not be limited to the following: 1. Percolation and infiltration tests conducted at a minimum of two locations or more per site to determine if the proposed site is hydrologically capable of accommodating the total amount of wastes discharged year around. Refer to Text Page 14; Table 1 ; Exhibit 4; Text Page 92; Table 23, p. 132. 2. Determination of the physical , chemical and biological properties of the wastewater to be applied, existing groundwater and the final mixture of both. Refer to Appendix J; Pages 79-100 3. An evaluation of the impact of salts from the wastewater on soils and receiving waters, (this should include weathering effects) . If the wastewater contains industrial wastes, the long range effect of heavy metals and other toxicants on soil properties and groundwater quality should be evaluated. Refer to Pages 79-100 • 4. An evaluation of the impact of nitrate after all nitrogenous con- • stituents have been oxidized to nitrate. • • • Refer to Pages 95-100 5. Information on net evaporation data. Refer to Appendix 6 ' Memo to WQC Division Interim Division guidance on planning and design review for land application systems. . March 18, 1977 . : , page2 - • The required detail will depend on the quantity and quality of the discharge and *the nature of the waste discharge requirements. - Additionally, if irrigation is a viable alternative, the applicant should furnish sufficient information to determing: 1. If drainage conditions are suited for raising good crops year after year for the life of the project. Refer to Pages 92-100 I. • If the soils are inherently capable of producing the yields contemplated in the project report. Refer to Page 92 ' • 3. . If planned methods of irrigation and application rates during a normal crop year are proper. Additionally, will the facilities be able to function _ properly under adverse conditions involving weather, pests, etc. Refer to Pages 92-100 4. If the cropping system will utilize the wastewater and/or nutrients applied to the land. - Refer to Pages 92-100 - 5. If the accumulation of heavy metals in growing crops and its subsequent _ concentration in the food chain presents serious health problems. Also, if using reclaimed wastewater for crop irrigation imposes undue risks to public health. Refer to Pages 92-100 -. 6. In the case of leased property, will the farmers fully cooperate for a reasonable life of the project. _ Refer to Appendix C These studies must be conducted in conjunction with the project report prior to selection of the recommended plan. GUIDELINES FOR LANDSCAPE IRRIGATION . 1. Since direct contact of treated wastewater and the public is possible, a minimum of secondary treatment, (BOD less than or equal to 30 mg/1 , Suspended Solids less than or equal to 30 mg/1 ) , with disinfection to below 200 Fecal Coliforms per 100m1 is required. Examples of this situation would include • irrigation of golf courses, parks, green belts, etc. Because of potential distribution system plugging problems, this type of reuse may also require filtration depending upon equipment used. 2. The discharge shall be confined to the area designated and approved for disposal and reuse. Irrigation should be controlled to minimize ponding of wastewater and runoff should be contained and properly disposed. Refer to Pages 68, 69 3. Maximum attainable separation of reclaimed water lines and domestic water lines should be practiced. • Refer to Pages 68, 69 4. All reclaimed water valves, outlets and/or sprinkler heads should be appropriately tagged to warn the public and/or employees that the water is not 'safe for drinking . Refer to Pages 68, 69 ill / _ Memo to WQC Division . Interim Division guidance on planning and design review for land application systems.III ./ March 18, 1977 - • page . 5. `All piping, valves and outlets should be color coded or otherwise marked • to differentiate reclaimed water from domestic or other water. Refer to Pages 68, 69 • 6. All reclaimed water valves, outlets and the sprinkler heads should be of a type that can only be operated by authorized personnel . Where hose con- nections are present on domestic and reclaimed water lines, different sizes should be established to preclude the interchange of hoses. Refer to Pages 68, 69 ' 7. Adequate means of notification shall be provided to inform the public and/or employees that reclaimed water is being used. Such notification should include the posting of conspicuous warning signs with proper wording of sufficient size to be clearly read. At golf courses notices should also be printed on score cards and at all water hazards containing reclaimed water. Refer to Pages 68, 69 8. Irrigation should be done so as to prevent or minimize contact by the public with the sprayed material and precautions should be taken to ensure that reclaimed water will not be sprayed on walkways, passing vehicles, buildings, picnic tables, domestic water facilities or areas not under the control of the user • iefer to. Pages 68, 69 a. Irrigation should be practiced during periods when the grounds . will have maximum opportunity to dry before use by the public unless provisions are made to exclude the public from area during and after spraying with reclaimed water,. . b. Windblown spray from the irrigation areas should not reach areas accessible to the public. ' c. Irrigated areas must be kept completely separated from domestic water wells and reservoirs. d. Drinking water fountains should be protected from direct or wind- blown reclaimed water spray. 9. Adequate measures should be taken to prevent the breeding of flies, . mosquitoes and other vectors of public health significance during the process of reuse. Refer to Pages 68, 69 10. Operation of the use area facilities should not create odors, slimes or unsightly deposits of sewage origin in places accessible to the public. Refer to Pages 68, 69 GUIDELINES FOR CROP IRRIGATION 1. Pretreatment requirements. • • • a. When there is no public contact with the treatment system, such as 0 . a totally fenced and properly signed pretreatment, wastewater conveyance, land application and disposal system, pretreatment requirements will be determined on Memo to WQC Division Interim Division guidance on planning and design review for land application systems. March 18, 1977 page 4 • a individual basis considering nuisance potential , potential for groundwater degradation and the treatment capability of the total system. Crops grown under these conditions shall not be consumed directly by humans. • b. When the effluent from the pretreatment facility is discharged to an irrigation ditch not controlled by the treatment entity and is conveyed to a land application system for final treatment and/or disposal , a minimum of secondary pretreatment, (BOD less than or equal to 30 mg/l , Suspended Solids less than or equal to 30 mg/1) ,. with disinfection is required since such irri- gation ditches are considered as "waters of the state." No specific disinfection standard is prescribed. • 2. Same as items 2 thru 10 under "GUIDELINES FOR LANDSCAPE IRRIGATION." • ..' .1 -I• , • I Frank J. Rozich, P.

Portions of uncultivated land in Alternatives 2, 3, and 4 were investigated. The inventory was not designed to cover all proposed impact areas and additional reconnaissance will be undertaken to complete cultural resource assessments of the project areas. Nine prehistoric cultural resources (5 WL413-421), consisting of three tool manufacturing/campsites, five isolated finds and one locality were recorded. None are of known age or cultural affilia- tion. IF's and the one locality are not eligible for nomination to the National Register of Historic Places, and no further work is recommended. The three sites, 5 WL416, 417 and 421, may contain significant subsurface deposits, and test excavation is recommended prior to ground disturbing activity and final National Register of Historic Places eligibility assessments. It is further recommended that pedestrian survey of cultivated/irrigated lands not be pre- requisite to project clearance. Cultural resource clearance of surveyed areas, contingent upon compliance with test excavation recommendations, is suggested. • " • Table of Contents Introduction 1 Phase 2 Survey Areas Figure 1 Phase 2 Survey Areas Figure 2 Description of Study Area 3 Project Area Provenience Figure 3 Project Area Provenience Figure 4 Inventory Methodology 4 Known Cultural Resources 7 Inventory Results 11 Collected Artifacts Figure 5 Interpretations of Data 16 Impact Assessment 23 Conclusions and Recommendations 24 Plates I - IV References Cited Appendix A: Greeley Wastewater Facilities Project Proposal for Cultural Resource Investigations Appendix B: Land Status/Landowner Communications Appendix C: Resource Locations and Descriptions Appendix D: Catalogue of Collected Materials • s This cultural resource inventory report is submitted in compliance with the stipulations of the National Environmental Policy Act of 1969, Executive Order 11593, the Archaeological and Historic Preservation Act of 1974, the National Historic Preservation Act of 1966, and the Colorado Land Use Act of 1974. It was prepared by Gordon & Kranzush, Inc. (GCK) at the request of ARIX to report the findings of field reconnaissance designed to locate, evalu- ate the significance of, and assess proposed impact to prehistoric and historic resources in portions of the Greeley Wastewater Treatment Facilities project area. This report constitutes the results of pedestrian reconnaissance of those areas common to all newly proposed wastewater treatment alternatives. Location of survey areas within each alternative project area is shown in Figures 1 and 2. ARIX and G6K have proposed to use data from this survey to project expected resource locations and densities in remaining project areas. Inventory of additional impact areas will be completed at such time that the total project acreage can be narrowed to those areas for which impact can be proposed with a reasonable degree of assurance. Appendix A, the Cultural Resource Inventory Proposal for the project,was reviewed and approved by the Office of the State Archaeologist of Colorado (OSAC), a review agency for the cultural resource investigations of this project (LeFree, personal communication) . At present, the Inventory Area (or Pedestrian Survey Area) for the Greeley Wastewater Facilities Project is included within a broader Research Area, for which study of previously recorded resources was completed in early 1979 (Phase I investigations). Designations, legal descriptions and in- • vestigatory methods employed for each cultural resource study area appear below. e 1 • -2- Research Area: Townships 4, 5, and 6 North, Ranges 63, 64, and 65 West, 6th P.M. , Weld County, Colorado.

Pedestrian Survey Zone 1 1 -3- S Description of Study Area The areas investigated as a portion of Greeley Wastewater Project cultural resource inventories span an elevation range of 4610 feet to 4650 feet (1405.1 to 1417.3 m. ), and are contained within the Colorado Piedmont section of the Great Plains Physiographic Province. Survey areas consist of low, rolling, stabilized or partially stabilized sand dunes, consisting of aeolian sand deposits of Quaternary age. Bedrock, exposed nowhere in the survey areas, consists of the Laramie-Vermejo, Fox Hills-Trinidad or Pierre sandstone and shale formations of Upper Cretaceous age. Native lithic materi- als noted include river cobbles or assorted siliceous materials. Although the South Platte River comprises the major, permanent water source for the area, investigated zones are drained by the south-flowing Crow and Tree Creeks, permanent tributaries of the South Platte. Numerous unnamed, seasonal drainage channels (Figures 3 and 4) are contained within survey area boundaries. Two ecological units were noted within survey area boundaries. Cul- tivated, agricultural crops, primarily corn, encompass almost all of the Wastewater Transmisssion Line right-of-way as well as the west half of Sec- tion 31, T6N, R63W. In these areas, natural contours as depicted on early (1950) quadrangles have been destroyed by annual cultivation. Vegetation is curtailed to cultivated, irrigated crops. Dryland areas (Section 6, east z Section 31) support prairie grassland • communities as modified in some areas by overgrazing. Rabbit brush, salt, blue grama,and buffalo grasses and prickly pear cacti were the most commonly s C �� D� R �/ oP • •; Figure 3: Project Area Provenience 2 I- _— _ i's.- .

Vegetation is generally sparse, allowing 50 to 75 percent ground surface visibility, but vegetation density increases in flood plains and drainage bottoms, decreasing ground surface visibility to near 0 percent. Antelope, coyote, jack and cottontail rabbits, rattlesnakes, night- and marshhawks, and a variety of songbirds comprise the commonly noted fauna. All areas investigated are totally exposed with vantage ranging from 0.5 mile to 10 miles (0.8 to 16 kilometers) depending upon location at crest or trough of the stabilized sand dunes. All aspects were represented in the elevated areas of the Storage Reservoir Site. Climatologically, the Greeley area is classified as semiarid with a low mean annual precipitation of approximately 11 inches (28 cm. ). Snowfall measures 0 approximately 32 inches (87 cm. ). Summer daytime temperature averages 70 F. O 0 0 (21 C. ) while the winter temperature range for the area is 25 to 35 F. 0 0 (-3. 8 to 1.5 C) (Environmental Protection Agency 1976: 22) . Inventory Methodology Objectives of this investigations were to locate, record, and evaluate in terms of eligibility for nomination to the National Register of Historic Places, cultural resources within certain proposed impact areas as delineated by ARIX and GCK. One hundred percent pedestrian survey coverage was applied at this time only to those alternative impact areas common to all newly proposed Alternative Facilities Plans (Figures 1 and 2). Furthermore, 100 percent pedestiran coverage, as described below, was applied only to those areas not • under cultivation/irrigation at the time of survey. Active agricultural areas I1 -5- were not examined due to negligible ground surface visibility resulting from vegetation and standing water, and previous disturbance in the forms of leveling and plowing. In addition, landowners expressed a desire that surveyors not disturb cultivated areas. One hundred percent pedestrian survey coverage was applied to all un- cultivated portions of Section 31, T6N, R63W and that portion of Section 6 , T5N, R63W contained within the proposed Storage Reservoir boundaries (Figure 3, Plate I). In these areas, 3 to 4 survey personnel walked parallel 20 foot (6 meter) corridors, seeking cultural resources in the forms of surface debris, structural remains and unnatural environmental disturbances. Survey corridors were narrowed upon discovery of cultural resources and intensive examination of the area was undertaken to determine the nature and extent of cultural re- mains. Site boundaries, localities and isolated finds were triangulated in relation to locatable cultural features (buildings, wells, road intersections depicted on the quadrangle, section corners, etc. ). Artifacts were counted and described by use of the "tally sheets" contained in Appendix C of this report. Uncultivated portions of the 60-foot (18.3 m. ) Transmission Line corridor, totalling less than one mile, were subjected to similar coverage. In some areas, relatively undisturbed land was examined on both sides of adjacent roads to account for minor realignments of the line in these areas. All investigated por- tions of the Transmission Line are flanked by county roads. What appears on the quadrangle to be undisturbed land in Sections 32 and 33, T6N, R64W and Sec- tions 4 and 5, T5N, R64W, is cultivated land. In actuality, a two-track road • parallels the Transmission Line in this area (Plate II). w , -6- • None of the project areas were staked, so survey areas were approximated from project area maps. In all cases, an attempt was made to cover at least a 50-foot buffer zone around all project areas. Cultural resources recorded during pedestrian survey fall into one of the following categories: prehistoric, or recent. Prehistoric remains consist of all aboriginal debris, structures, and disturbances with origins believed to predate European contact in the area (ca. 1835). Recent remains include all evidence of human activity postdating 1930. The following system is used in classifying the extent and size of cultural resources located during pedestrian survey. Prehistoric site: concentration of more than five artifacts, including debitage, within a 10 m. radius, or, structural remains believed to be of prehistoric origin. Prehistoric locality: concentration of two to five artifacts, including debitage, within a 10 m. radius, or, more numerous artifacts spread across a large area. Prehistoric isolated find: a single artifact that is not within a 20 meter radius of an identified site or locality; an isolated find cannot be shown to be associated with another isolated find, locality, or site. Colorado State Archaeological Site Inventory forms have been completed for all sites and have been filed with the OSAC. OSAC IF forms were completed for all localities and isolated finds. All prehistoric resources were assigned Smithson- ian trinomial designations. Recordation materials are contained in Appendix C of this report. Landowners were notified of collection of artifacts from private land and will be given the opportunity to reclaim cultural materials (Appendix B). Arti- • facts not claimed, and those collected from State land, will be curated by the University of Colorado Museum, Boulder, Colorado. Field journals, additional -7- photographs and negatives will remain available on request from Gordon & Kranzush, Inc. , Boulder, Colorado. Copies of this report will be filed with OSAC, the University of Colorado Museum, ARIX, EPA, the City of Greeley, and GgK. Known Cultural Resources Extensive research into the culture history of, and previously recorded cultural resources in the Greeley Research Area was conducted early in 1979. Numerous sources present confusing and sometimes conflicting data. No previously recorded archaeological, historical or National Register of Historic Places resources are located within impact area boundaries as described for this inventory. However, several archaeological and historical sites are located within the Greeley Research Area and these sites, along with well-estab- lished regional patterns and sites from surrounding areas help to form a gross culture history that will be assumed for this area. The Delta Site Pumping Station (Figure 4) was investigated by Cultural Resource Consultants (Patterson and Tipps 1978) for CH2M-Hill, Inc. Prehis- toric resources encountered were two retouched flakes, one exhibiting wear at- tributed to utilization. Reports of local artifact collecting and use of one of the ranches as a "gathering place of the whites during 'Indian scares'" leads the authors to conclude that sediment aggradation, alluviation, low ground surface visibility due to dense riparian vegetation, and/or artifact collection throughout the historic and recent periods may have been determining factors in • the small number of prehistoric resources encountered. Construction surveil- -8- lance was recommended for this area due to the high probability of subsurface cultural remains in flood plain contexts. CRC did locate an historic structure judged to be of state and possibly national significance on the basis of association with an historically important family, certain architectural characteristics, and construction methods. This structure is located slightly north and west of the intersection of the Trans- mission Line with the Delta Site and will not be affected by this construction. William Wylie settled this area in 1859, homesteaded in 1866, and acquired title in 1869 (Ibid. : 9). The structure in question probably dates to the 1860's. The Greeley region is abundant in prehistoric and historic sites, and the project area is located in a region for which at least a general culture history is known. Paleo-Indian occupation of the region is documented by several sites, the closest of which is the Powars Site near Kersey,Colorado. Excavated in 1937 by F.H.H. Roberts, the Powars Site yielded Folsom projectile points, flakes and scrapers attesting to the occupation of the area by nomadic hunters of extinct species of large game, probably between 9000 and 8000 years B.C. Archaic sites (4000 B.C. - A.D.1; Willey 1966: 313), or sites firmly identified as having Archaic components, are not recorded for the general re- search area. It is probable that sites and isolated finds associated with this period of switch to a broader based subsistence exist in the area but due to lack of diagnostic or dated remains, have not been interpretted as such. It is also possible that cultural remains of this period largely lack surface ex- posure, and have therefore not been recorded. • At least six Plains Woodland sites (ca. A.D. 1 to A.D. 1000; Ibid. ) are recorded for the Greeley Research area. These sites contain cord-marked -9_ I pottery, small side-. or corner-notched projectile points, groundstone arti- facts, and frequently, features such as cache pits, hearths, and tipi rings. The Plains Woodland Tradition is assumed to represent a westward expansion of the Woodland culture of the midwest. Although evidence of agriculture is often found in association with Woodland sites in the midwest, it is believed that agriculture was not practicied west of the 99th meridian (Wedel 1961: 104). Several of these sites have been examined by Dr. Bruce Lutz of the University of Northern Colorado (personal communication) , and one, 5 WL51, is suspected of having Paleo-Indian components in its lower horizons. Two of the sites, 5 WL388 and 5 WL417, were poorly recorded and as a result, exact lo- cation is not known. The Plains Village period (A.D. 1000 to A.D. 1650; Willey 1966: 312) may also exist in a modified form in Northeast Colorado. Though Upper Republican "villages" similar to those found in Kansas and Nebraska have not been recorded in the Research Area, it is possible that, with extended survey and/or excava- tion, Upper Republican artifacts will be found in this area. Similarly, although no sites recognized as such have been recorded in the Research Area, sites associated with Plains Apache (Dismal River; ca. 1650 to 1750; Gunnerson 1966) , Comanche, Shoshone, Arapahoe, Cheyenne, and possibly Ute (Buckles 1968) , dating from the seventeenth through the nineteenth cen- turies, may be present in the area. The Research Area contains many historic sites which represent the complete historic period of the Greeley region. The grave of the first permanent settler in Weld County, Elbridge Gerry, is located in T5N, R63W, and has an 1840 date • ' 1 • -10- • of significance. No development is currently proposed in this area. Numerous historic trails and expedition routes are contained within the South Platte River floodplain corridor. These include - the route of the Long Expedition (1820) to explore the southwest portion of the Louisianna Purchase (62/07/0023). - the First Fremont Expedition (1842) to explore the Rocky Mountain region. - Trappers Trail (Cherokee Trail) which followed the south side of the South Platte from Denver to Latham and continued up Crow Creek into Wyoming; this is the oldest trail running through the Front Range of Colorado; in 1848, a band of Cherokee Indians following this trail reported discoveries of gold on the Arkansas. River-Denver portion of this trail, thereby helping to spur the Pike's Peak gold rush in 1859. - Dodge Trail (1834) , followed by Colonel Henry Dodge on a military and exploratory expedition (62/07/0031) . - Platte River Trail, a former game and Indian trail, used by early settlers (62/07/0024) . - Holladay's Overland Express, an 1862 travel route that followed the South Platte from Julesberg to Denver ;. an 1864 stage route change excluded this area; in 1866, the company merged with Wells Fargo (62/07/0032) . - Overland Trail and Stage Route, established in 1859 by Jones, Russell and Co. ; led to much ranch and stage station construc- tion in 15 to 25 mile intervals along the route (62/07/0025). - Union Pacific Railroad/Colorado Central Railroad; after the Union Pacific built its trascontinental route through Wyoming, the people of Colorado looked to the Colorado Central Railroad for branch lines; CCRR promoter was W.A.H. Loveland; the first rail transportation to the South Platte Valley east of Greeley was provided by the Julesberg Cutoff, completed in 1882. Though historically significant in terms of exploration and settlement of Colorado, the CHS-DHP considers development in this corridor to have adverse impact to these sites only if construction affects physical remains of the routes (stage stations, campsites, etc.) (Patterson, personal communication). Numerous additional historic sites are assoicated with utilization, construc- tion and operation of the above lines,routes and trails. Such sites include - Twin Buttes Campground (62/07/0021) , a grove of trees used as a campsite by numerous early emigrants and during the 1859 gold • rush. - Hardin (62/07/0043) , platted in 1906, but probably settled during the 1860's and 70's; owned by Union Pacific. 7r -11- • - Kuner (62/07/0044) , platted in 1908, the former site of a Kuner picle factory; owned by Union Pacific. - Kersey (62/07/0045) , originally named Orr, platted in 1894, owned by Union Pacific. - Hoover Ditch (62/07/0085) ,earliest priority (1868) on the South Platte River. - Greeley Ditch No. 2, (62/07/0011) also known as the Cache La Poudre Canal, constructed in 1870 by the Union Colony for irrigation of Colony farms; purchased by users in 1878. The Larimer-Weld Council of Governments has reported a supposedly complete inventory of archaeological and historic sites in this two-county area. The inventory is incomplete (Handy, personal communication) , and therefore has not been used in this project. Greeley Wastewater Project developments in the survey areas discussed herein will not affect these previously recorded historic sites. Potential impact and affect to any of these sites will be discussed in future reports of pedestrian reconnaissance. Inventory Results Pedestrian survey resulted in the recordation of three prehistoric campsites/lithic tool manufacturing sites, one prehistoric locality, and five prehistoric isolated finds. Each will be discussed separately, below. OSAC recordation forms for each resource are contained in Appendix C of this report. 5 WL413 consists of an isolated, grey chalcedony, secondary decortication flake upon which has been created a small spur. The artifact may have functioned as a graver, but cultural and temporal affiliations are unknown. 5 WL413 was not collected. • 5 WL414 consists of a single, tan fine-grained quartzite, interior -12- percussion flake exhibiting nibbling on lateral and distal edges. The artifact is not culturally or temporally diagnostic, and function is difficult to ascertain. The artifact was not collected. 5 WL415 consists of an isolated, pink and tan fine-grained quartzite primary cobble decortication percussion flake with no secondary modification. The arti- fact was not collected. Functional, cultural and temporal affiliations are un- known. 5 WL418 is an isolated pink and black chert, unifacially retouched interior percussion flake fragment. The artifact may constitute a portion of a unifacial tool discarded after breakage. Cultural and temporal affiliations are unknown. The artifact was not collected. 5 WL419 consists of a small, white chert, interior percussion flake fragment. It was recorded within sufficient proximity to site 5 WL416 (see below) that it is reasonable to suspect that 5 WL419 may represent an un- defined activity peripheral to that site, though cultural and/or temporal association is speculative at best. The artifact was not collected. The single locality recorded, 5 WL420, consists of two flake fragments in association with a small deposit of siliceous river cobbles. One artifact is a small, dark brown chert, primary cobble decortication flake; the other is a yellow, fine-grained quartzite interior percussion flake. Neither of the artifacts were collected. 5 WL413, 414, 415, 418, 419, and 420 were discovered in elevated areas surrounding a small, unnamed intermittent tributary of Crow Creek. Vegetation in the area consists of grasses, forbs, and cacti noted in the prairie grass- land community (page 3) . None of these resources were_discovered in the • drainage flood plain; perhaps decreased ground surface visibility prevented -13- resource recognition in these areas. 5 WL416 (Plate IIIb) is an aboriginal campsite discovered on the crest and north-facing slope of a low, stabilized sand dune, located east of an unnamed seasonal drainage. One hundred fourteen items consisting of chert and quartzite cores, primary and secondary decortication flakes and retouched and unretouched interior percussion flakes were recorded. In addition to debitage, five mano fragments of quartz, quartzite and sandstone, a sandstone metate fragment, three biface fragments, a small tabular piece of sandstone with two ground facets, a calcified large mammal longbone fragment, and a burned rock fragment were recorded. No culturally or temporally diagnostic materials were located. A complete record of site contents is contained in Appendix C of this report. Site surface area is estimated at approximately 5.4 acres. One artifact, GK-79-4L133, was collected. The item (Figure 5) is a brown chert biface fragment with dorsal facial thinning and bifacial primary and secondary edge retouch. The item exhibits rounding on all edges and flake ridges, and left lateral edge polish. 5 WL416 is totally open and exposed, and a slight north-northwest aspect is provided by the gentle slope of the stabilized sand ridge on which the site is located. Vantage is excellent north along the small drainage and northwest and west across level to gently rolling terrain. Vantage to the east and south- east is somewhat restricted by gentle, yet consistent, rises in terrain. Vegetation on the site consists of grasses, forbs and cacti, allowing 50 to 75 percent summer ground surface visibility. • -14- • Several of the artifacts noted were only partially exposed to the ground surface, and therefore, it is considered probable that at least shallow, subsurface deposits exist within the loose, sandy, soil. Though disturbance of the site by humans or livestock is not evident, the surface distribution of artifacts -- that is, across the ridge crest and down its north-facing slopes -- suggests that on-going erosion of site deposits is probable. 5 WL417 (Plate IIIc) consists of a small concentration of chipping debris and tools located at the head of a small seasonal drainage on two low, stabilized dunes. The eastern portion of the site consists of chipping debris and two mano/hammerstone fragments interspersed with fragments, cobbles and pebbles of naturally occurring siliceous materials. The western portion of the site con- tains small amounts of chipping debris, three metate fragments , and a small sandstone abrader or polishing stone (Plate IVa). Total artifact content for the site is 46 items. A small, red and black chert, secondary decortication scraper fragment (GK-79-#134) was collected from the western concentration of the site (Figure 5). The item exhibits steep, parallel dorsal distal edge retouch and slight distal edge attrition from scalar and step flaking. The two 5 WL417 artifact concentrations are separated by a broad depression in which no cultural materials were discovered. Possible explanations for the recorded surface distribution will be discussed in the following section of this report. 5 WL417 is totally open and exposed, and has a westerly aspect. Good vantage to the northwest, west and southwest is available, with vantage in other directions somewhat limited by rises in terrain. In terms of vegetation and ground surface visibility, 5 WL417 is very similar to 5 WL416. Evidence of 1 -15- I erosion is more pronounced, however, and rounded chert, quartzite and quartz cobbles appear to be continuously eroding from the west-facing site slope. 5 WL421 is very similar to 5 WL416 in content and characteristics. The site covers a small, stabilized sand ridge which protrudes south into the flood plain of a small, unnamed seasonal drainage. Recorded lithic artifacts, primarily debitage, number 132 items. Artifacts consist of chert, chalcedony quartzite and siltstone cores, fragments, primary and secondary decortication flakes, and retouched and unmodified interior percussion flakes. (It is certain that more lithic artifacts exist within site boundaries; however, the presence of at least three rattlesnakes in the site area prevented complete location and recordation of 5 WL421 materials. ) In addition, a burned, large mammal longbone fragment, a fire-reddened sandstone fragment, a small tabular sandstone fragment with one ground facet, and a quartz mano fragment were recorded. Two finished tools were collected. GK-79-#131 is a small, grey/white chert, probably corner-notched projectile point fragment with straight base. The right lateral edge has been reworked above the base to give a straight-edged and side-notched appearance (Figure 5). GK-79-#132 is a tan chalcedony, bifacial tool fragment with parallel edge retouch and extensive dorsal lateral edge step flaking. An attempt to remove the bulb of percussion from the flake has re- sulted in two deep flake scars on the ventral surface. #132 may be a portion of a knife or scraper (Figure 5). A dense concentration of lithic materials measuring less than 1 meter in radius and containing 33 items (primarily interior percussion flakes) was noted in the southern portion of the site, on the west-facing slope of the ridge. Pos- • sible explanations for this feature will be discussed in "Interpretations of Data". Figure 5: Collected Artifacts • '--- . .r' r t %14tilk a. GK-79—#133 5 WL416 •ve,:x`- ,.Ite4 _ fW rAll b.

Soil consists of very loose sands and summer ground surface visibility ranges from 60 to 80 percent. Extensive cactus patches mixed with sparse grasses and forbs comprise the site vegetation. Evidence of site dis- turbance in the forms of numerous shotgun and rifle cartridges as well as some livestock disturbance was recorded. Excellent vantage to the west, south and southeast is available from the central portion of the site, but slight rises in terrain to the east of the drainage channel and the north curtail extended vantage in these directions. Recent cultural resources noted within survey areas include cultivation disturbance, livestock disturbance, roads, fences, wells, trash (glass bottle fragments, cans, etc. ) , and houses and other structures as noted on the quad- rangle. Interpretations of Data Cultural resources of recent origins, mentioned above, are of no historical significance and warrant no further attention. All are representative of regional agricultural and grazing land uses. Prehistoric resources can be interpretted in terms of such concerns as function, location, content and significance, and can be viewed in individual and regional contexts. Resources will first be discussed separately, and will then be viewed as a unit representing a sample of the regional resource base. • In terms of suggested functions, prehistoric sites 5 WL416, 417 and 421 all appear to have been tool manufacturing and campsites. In addition, the r -17- • presence of bone fragments at sites 5 WL416 and 421 may indicate use of those sites for hunting and/or butchering activities as well. The 5 WL416 debitage assemblage (Appendix C) is dominated (48.6%) by interior percussion flakes of cherts, quartzites, chalcedonies and petrified wood, indicating that tool manufacturing was a primary site function. Cores and unmodified fragments of usable lithic materials account for 8.4% of the assemblage, suggesting that knapping activity may have been concentrated in the later stages of tool manufacture. The fact that only one core was recorded, a tan, fine-grained quartzite specimen, may corroborate this hypothesis, although primary core reduction is represented by primary and secondary de- cortication flakes of this and other materials. 9.3% of the assemblage consists of microflakes, indicating that tool finishing and/or resharpening was also undertaken at the site. Groundstone fragments indicate site utilization as a vegetal food processing area, and contribute to assignation of a campsite function, since such bulky artifacts were rarely transported to sites of brief, opportunistic quarrying, hunting, etc. Burned rock suggests the presence of a hearth at one time. Functions of the small, tabular grinding stone are unknown, but the item appears to have been used as an abrader or polisher. The mammal long bone fragment, in combination with bifaces and a scraper suggest that hunting and/or butchering activities also took place at the site, although such an hypothesis based on this limited data must be regarded as tenu- ous. GK-79-#133 wear patterns may have resulted from sand abrasion, and are therefore rejected as functional evidence. The presence of partially exposed artifacts within site boundaries indi- • cates a high probability of subsurface cultural remains. Though cultural and -18- temporal affiliations of this site cannot be assessed on the basis of the surface data, subsurface strata may contain diagnostic remains and/or datable deposits that are significant in terms of assessing the site's position within the regional culture history. 5 WL416 may have the potential for yielding additional data of significance to the understanding of areal prehistory, but subsurface probing is necessary to confirm the presence or absence of subsurface components. On the basis of surface data, 5 WL416 does not meet eligibility criteria for nomination to the National Register of Historic Places (NRHP). However, a final significance assessment should be delayed until quantitative and qualitative assessments of subsurface cultural components can be made. 5 WL417 appears to have functioned primarily as a raw lithic material source and tool manufacturing site, although the presence of grinding implements and an abrader/polisher may indicate utilization as a campsite as well. The eastern portion of the site consists almost entirely (93.7%) of chipping debris. The two mano fragments recorded in this area also show evidence of use as hammer- stones suggesting that these artifacts may have been reutilized, and that tool manufacture may have been the only activity in the eastern portion of the site. The small material assemblage noted in the western portion of the site may represent a campsite component of 5 WL41.7. Debitage is sparse, and metate fragments indicate that vegetal food processing was undertaken in this area. Mano/hammerstones in the eastern concentration may have come from this area. GK-79-#134, a small scraper fragment, exhibits distal edge use wear that may have resulted from use in scraping somewhat resistant materials, although the wear data are not so conclusive as to rule out incidental damage after • discard. Both site components may extend or may have extended into the depression ■ -19- currently separating the concentrations. It is possible that alluvial or colluvial fill is obscuring cultural materials in this area, and that surface materials noted in elevated portions of the site comprise the only surface exposures of the site. The investigators consider the probability of subsurface deposits within or between concentration boundaries to be high. Consequently, although surface manifestations of 5 WL417 do not meet criteria for nomination to the NRHP, the possibility that potential subsurface strata may contain cul- tural, temporal and functional data of significance to the understanding of regional prehistory renders the site worthy of further examinations. Final significance assessment should be delayed until this possibility can be further explored. 5 WL421 is similar in content and configuration to 5 WL416. The projectile point fragment recovered from the site is thought to be of little diagnostic value, since both corner and side notching of small points is common through- out the Late Prehistoric period in the Plains, and since reworking of the speci- men prevents comparison with points from dated levels of excavated sites in the region. The site probably functioned as a tool manufacturing locus, based on the presence of extensive debitage deposits representing all stages of lithic tool manufacture (Appendix C). Again, the preponderance of interior percussion flakes and relative paucity of primary and secondary decortication flakes and cores of the most common lithic materials represented in the interior percussion flake assemblage suggest that knapping activity was primarily confined to the later stages of lithic tool manufacture. Groundstone fragments as well as • bone and burned sandstone suggest that the site also functioned as a campsite. The possibility of hunting and/or butchering in the area is recognized as it was for 5 WL416. -20- Collected artifact GK-79-#132 exhibits lateral edge step flaking which may indicate use in scraping resistant material (possibly bone?). The flake concentration recorded within 5 WL421 boundaries may represent an area of concentrated chipping activity or may be the discard pile of a site vandal. The evidence of site disturbance by hunters renders the latter possibility quite likely. Due to recordation of partially exposed artifacts and the nature of the loose, aeolian sand deposits, it is considered likely that 5 WL421 contains at least shallow subsurface cultural deposits which could aid in ascertaining site functions as well as cultural affiliations and period of artifact deposi- tion. 5 WL421 may be eligible for nomination to the NRHP if subsurface strata contain data meaningful to these ends. It is suggested that final eligibility determination be delayed until the nature and extent of subsurface cultural material can be ascertained. Two additional observations can be made regarding potential significance of relatively undisturbed cultural deposits within 5 WL416, 417, and 421 boundaries. It has been noted by G&K in similar aeolian sand deposits in both this region and others (Gordon and Kranzush 1978; Kranzush and Gordon 1978) that surface exposure of cultural resources may not accurately reflect true re- source density and that disturbance and/or deflation of stabilized sand may cor- e rolate positively with surface distributions of resources in those areas. In other words, it is quite probable that sites with surface exposures constitute only a fraction of the true resource base, and that deposits of comparable age, as well as older and more recent remains, exist in subsurface positions. When Senvironmental conditions dictate that prehistory must be documented on the basis of a portion of the resource base, it is considered necessary that sites with • t -21- • surface exposures and the potential for undisturbed subsurface deposits be fully explored prior to final evaluation of significance and accompanying data protection/preservation/extraction recommendations. Assessment of previously recorded resources in the vicinity of the Greeley Wastewater Facilities Project (pages 7 through 11) indicates that many periods of prehistory (e.g. Paleo-Indian, Archaic, Protohistoric) have been inadequately documented in this area. The spread of cultivation, agriculture and urban expansion and the ever-present (and in this case, long history of) site vandalism threaten to destroy the physical remains of the prehistoric cultural record prior to adequate documentation. It is therefore considered necessary to ade- quately study any intact aboriginal remains prior to a final decision regarding overall significance. In other words, in the absence of a complete, well- documented data base, all data becomes meaningful. The five isolated finds and one locality recorded during this investigation can individually add little additional data to the understanding of prehistoric utilization of the area. Several observations regarding artifact associations and locations can, however, be made. It is possible that IF 5 WL419, a single flake, is associated with site 5 WL416, based on the proximity of the two resources. However, due to absence of surface materials in the area separating the two resources, and the nondiagnos- tic natures of the recorded artifacts (precluding any more than locational associ- ation) separate designations will be maintained until such time that clear association can be documented. The one locality recorded, 5 WL420, appears to be associated with site • 5 WL417, at least functionally and localtionally. Again, the nondiagnostic 1 -22- nature of the remains prevents hypotheses of cultural or temporal associations. It is considered probable that 5 WL420 represents opportunistic use of exposed stream cobble deposits for the purposes of tool manufacture, and that similar resources will be encountered throughout the region. The locational pattern exhibited by the 9 recorded resources was anticipated, and is useful in terms of planning the next phases of cultural resource in- ventory. All three sites are located adjacent to or in close proximity to the seasonal drainage channel contained within the survey area, while most iso- lated finds are more or less evenly distributed throughout the upland areas. It is hypothesized that stream proximity was important to prehistoric groups for water sources and game and vegetal foods availability. The availability of utilizable lithic materials associated with this drainage channel is an additional benefit. The applicability of this model for site location will be further evaluated in future Greeley Wastewater Project reconnaissance. Isolated finds were encountered with somewhat greater frequency than was expected. An additional hypothesis that will be tested in Phase IV investigations is that isolated artifacts occur with greater frequency in areas where raw lithic materials are readily available. Easy access to raw materials may have resulted in a greater frequency of artifact loss or discard. In summary, the three tool manufacturing/campsites recorded in this inven- tory may contain significant subsurface components, and although 5 WL416, 417 and 421 are not deemed eligible for nomination to the NRHP on the basis of sur- face indications, any buried site components should be evaluated prior to final NRHP eligibility assessments. Isolated finds 413, 414, 415, 418 and 419, and • locality 5 WL420 are not considered significant to the understanding of pre- 1 j -23- S historic areal exploitation patterns and are deemed ineligible for nomination to the NRHP. No hypotheses regarding cultural or temporal affiliations of sites or isolated finds can be advanced at this time due to lack of diagnostic remains. Impact Assessment The following list includes resource designations, the Alternative(s) which will result in impact to each resource, and the nature of the proposed impact. Those resources which will be subjected to adverse impact will be further discussed in the next section of this report. The isolated finds and locality are considered to have low potential for contributing to the understanding of areal prehistory, and therefore, impact from facilities construction is not considered adverse in nature.

Implementation of Alternatives 2, 3, or 4 will affect sites 5 WL416 and 417; 5 WL421 will be affected by implementation of Alternatives 3 or 4. It is therefore recommended that, prior to commencement of any ground disturbing activities in these areas, test excavation be undertaken to determine the nature and extent of subsurface components of these sites. Final NRHP eligibility assessment should be made on the basis of survey and excavation data. Such measures designed to retrieve data prior to site destruction/dis- turbance are considered sufficient to allow a determination of No Adverse Effect. Isolated Finds 5 WL413, 414, 415, 418, and 419 and Locality 5 WL420 are not eligible for nomination to the NRHP and, since locations and descriptions have been recorded, no further work is recommended. It is further recommended that pedestrian survey of heavily cultivated and/or irrigated cropland not be required by OSAC or EPA as a portion of the re- maining cultural resource evaluation of the Greeley Wastewater Facilities Project due to extensive, long-standing disturbance of these areas. It is suggested that any pedestrian coverage of these areas be left to the discretion of the cultural resource manager performing the evaluation. If pedestrian survey of cultivated lands is required, winter investigations will be necessary to insure adequate ground surface visibility and landowner concurrence. Inasmuch as development of the survey areas described herein for use as -25- • wastewater treatment facilities will affect no previously recorded historic or prehistoric resources, and inasmuch as mitigation measures as described above, designed to avert adverse impact to cultural resources, have been recommended for areas associated with Alternatives 2, 3, and 4, it is recommended that the City of Greeley be granted cultural resource clearance, contingent upon com- pliance with recommendations advanced above, to proceed with developments in the inventory areas described in this report. It is understood that impact areas associated with any alternative that have not been subjected to cultural resource reconnaissance must be investigated prior to final project clearance. • t • PLATE I • • 1'Vn1S:tffrth?hs,.iar...14r`.R'tic!..lt SYytV-1.—}'f;- . _1' 7•:T ,rT-'1 FY ?t.: .-!,1$' ,- [[.,.+ M1b:�f+;. : :-,--,--,-.. -_-.-,.,,!.,:.--.-.,--22;‘:-�_ 'A _ _ _ �.`"chi _ h�-.�..�Y�•,...:.^ `sµ Yj' v-,_,-z,-.;s.ra•!':' �' _ '-ii.s+�- - "'- of�7�r_ .•n �.-,7- ,>,'� "7,T'"hi.�t l J•�,-_ .?;,..r:-.-,^it.�,0.-,, "` . .. n -•,,,`;'--L ,.•r -7-I--.+.--:%-rta_:,- � :_z ---,,t♦„_ '_!•fe�-- ,t•-. .,'-'_.- t.:• _ 7. a`•t _ -• •C.,•�y.-• 4 r.i•'�s Cry _ Ate' M_Si� 'S,, _ -.1,,:r.„..., - , K'�.T •Car .L.y '.."-*.7....-1.'.:T-..;:',4`:.

Gordon E rush, Inc. 2920 Pearl Street • Boulder, Colorado 80301 • (303) 443-4490 Cultural Resource Services PROPOSAL - Cultural Resource Inventory Greeley Wastewater Facilities Plan Project Compliance with antiquities legislation for the Greeley Wastewater Facilities Plan Project will involve five phases of study designed to deter- mine that no properties of National Register of Historic Places eligibility will be adversely affected by proposed actions. Phase 1 of the project, consisting of research of archaeological and historical records to ascer- tain whether sites of known National Register significance have been re- corded within project area boundaries, has been completed (May 1, 1979) . No current National Register properties are located within study area boundaries. However, it has been recommended that the grave of the first permanent settler of Weld County, Twin Buttes Campground, Hardin and Kuner, all listed with the Colorado Historical Society-Department of Historic Preserva- tion, be avoided in the planning of wastewater treatment facilities. In ad- dition, the existence of numerous historic routes of travel paralleling the South Platte River suggests that significant historic remains may be located within the floodplain corridor. The only archaeological site recorded in the project area, 5 WL183, will require additional investigation to determine significance and eligibility for nomination to the National Register of Historic Places. • Existence of recorded archaeological and historic sites within project area boundaries implies that cultural resource reconnaissance has been con- y i, -2- ducted within the study area in the past. Such studies include examination of the Delta Site (Patterson and Tipps 1978) , as well as numerous individu- al historic site recordations. Because the area has been incompletely in- ventoried, Phase 2, pedestrian survey of proposed impact areas, will be implemented. It has been the past experience of this firm in dealing with 201 Plans that it is very difficult to coordinate facilities planning with cultural resource investigation. Because an extensive cultural resource inventory necessitates isolation of all proposed impact areas at the very beginning of the planning stages, it often results that those impact areas proposed in the later stages of the project, as well as facility relocation resulting from evaluation of alternatives, are excluded from the inventory area. This constitutes noncompliance with antiquities legislation and often results in facilities plan or construction set-backs. Similarly, the cost of one hundred percent pedestrian survey of all suggested facilities treatment alternatives, particularly in the case of a large study areas such as is involved in the Greeley project, is often pro- hibitive. Although large tract surveys are in many ways more desirable from a cultural resource viewpoint, this firm takes the position that in cases of possible funding restrictions, in-depth analysis and evaluation of a smaller area is preferable to a more limited view of an extended tract. Though 201 funding usually allows for site location• in combined alternative project areas, analysis and application of data recorded during survey is restricted. • Improper or inadequate analysis can lead to inaccurate site significance assessment; it almost invariably results in a document that is of little use in planning future developments in surrounding areas in that 7 I -3- . 0 resource densities and distributions are not predicted on the basis of patterns derived from analysis of survey data. When the reconnaissance area is narrowed, sufficient funding is available to address such concerns as site selection criteria, diachronic land use patterns, and the all too often ignored historic land use studies. Therefore, aK, Inc. has isolated certain components of Greeley facilities plan alternatives to investigate as Phase 2 of the project. These areas consist of those primary impact zones common to the Direct Discharge to Crow Creek, Discharge to Existing Ditches and River Discharge/Recharge, and Land Application for Crop Production alternatives. It has been determined that the Storage Reservoir proposed for the TON, R63W, Section 31 area will most probably be used in the final Wastewater Facilities Plan. As cur- rently proposed, the reservoir and associated treatment site(s) will encom- pass an area of approximately 11 section, or 800 acres. Due to the nature of proposed impact, that is, reservoir construction, this area also deserves cultural resource priority in light of the possible impact mitigation or project relocation that may become necessary in the event that National Register eligible sites are contained within its boundaries. In addition, Phase 2 will include inventory of the Transmission Line linking the Delta Site Pumping Station (already inventoried) with the Storage Reservoir. One hundred percent pedestrian survey of these areas will be implemented to determine the nature and extent of unrecorded historic and prehistoric cultural remains.In conducting this phase of investigation, survey personnel walk parallel corridors of varying width depending upon such factors as • ground surface visibility and terrain. Cultural remains are sought in the forms of surface debris, structural remains, and unnatural environmental -4- disturbances. Upon discovery, cultural materials are described, surface distributions are mapped, and the area is photographed. If it is felt that collection of an artifact sample will aid in assessing the signifi- cance of a resource, cultural materials may be returned to the laboratory. In addition, any specimens that are diagnostic of site cultural or temporal affiliation will be collected. Where lands are privately owned, an offer to return collected specimens to the landowner is made, but landowners are encouraged to allow museum curation of artifacts. Collections from State lands and those assemblages not claimed by private landowners will be curated by the University of Colorado Museum, Boulder, Colorado. At the completion of this phase of work, the output will be precise location and recordation of all cultural resources located within survey area boundaries. Phase 3 of the study will consist of artifact and site location analysis,and interpretation and significance assessment of cultural resources. All re- sources must be assessed in terms of eligibility for nomination to the National Register of Historic Places. Factors influencing this decision in- clude such criteria as uniqueness, association with an historically famous person, family or business, and potential for yielding further information of significance to Prehistory or History. The nature of the impact to cultural resources that will result from project implementation is also determined. Finally, if necessary, measures must be designed to avert adverse impact to significant resources. A summary of areas investigated, resources encountered, significance of the various sites, and potential impact mitigation alternatives will be supplied to ARIX by July 21, 1979 • for inclusion in the preliminary Facilities Plan. When preliminary alternative assessments are complete, a plan for I -5- • completion of cultural resource inventory will be formulated. Impact areas associated with specific feasible alternatives will be investigated as Phase 4 of this project. This may involve examination of ditches and/ or streams, investigation of proposed new crop areas, or inventory of re- charge areas. It is hoped that by this time, all impact areas will be concisely defined for purposes of cultural resource investigation. It is anticipated that small, primary impact zones such as ditches , canals or additional treatment sites will be subjected to one hundred percent pedes- trian survey, while it is possible that new crop production areas, depending upon size, will be investigated by implementation of a stratified sampling technique to be based upon such site location variables as may become apparent during Phase 3 survey and analysis. Again, a summary statement, including a list of all resources located during Phases 3 and 4, substantiated significance assessments and impact mitigation recommendations , will be sub- mitted to ARIX for inclusion in the Final Wastewater Facilities Plan, on or before September 10, 1979. Phase 5 will consist of preparation of the Final Cultural Resource In- ventory Report for submittal to the Office of the State Archaeologist of Colorado, Colorado Historical Society-Department of Historic Preservation, and Environmental Protection Agency. Although every attempt will be made to complete this document by September 10, 1979, the nature and densities of resources encountered may necessitate an extension of analysis and reporting time. In any event, the formal cultural resource inventory docu- ment will be submitted no later than September 30, 1979. • T 0 APPENDIX B: Land Status Landowner Communications • .144"1-\\/ • ,F o MAE 1" L 5' ' nd tat , �—� -., at \---'--t? ) ezD -i------f-2.. --4; __'). .:1:: :..2z..n_...\,) ) , . . -4, . ----.._ r-_, ‘.... n ..„,.___: -1:7 ,,____ ,,.,„ ,. ,,,... s\_..) . ___ /„....) .,..:.,. ... . ••=4 0 o op it 11 3 •' s•:` .....L`i �` o / n 4-' �O • a U] / ..."--a cr) • j. -% '• . :'. ..., ‘-- i c.) . +- is i c : ..n „-- ..., -"\_.
