There is a close correlation between wind erosion and the texture of the surface layer, the size and durability of surface clods, rock fragments, organic matter, and a calcareous reaction. Soil moisture and frozen soil layers also influence wind erosion. Rating Options Units of Measure: tons per acre per year Aggregation Method: Dominant Condition Component Percent Cutoff.'

The estimates are used in land use planning that involves engineering considerations. Hydrologic soil groups are based on estimates of runoff potential. Soils are assigned to one of four groups according to the rate of water infiltration when the soils are not protected by vegetation, are thoroughly wet, and receive precipitation from long-duration storms. The four hydrologic soil groups are: Group A. Soils having a high infiltration rate (low runoff potential)when thoroughly wet. These consist mainly of deep, well drained to excessively drained sands or gravelly sands. These soils have a high rate of water transmission. Group B. Soils having a moderate infiltration rate when thoroughly wet. These consist chiefly of moderately deep or deep, moderately well drained or well drained soils that have moderately fine texture to moderately coarse texture. These soils have a moderate rate of water transmission. Group C. Soils having a slow infiltration rate when thoroughly wet. These consist chiefly of soils having a layer that impedes the downward movement of water or soils of moderately fine texture or fine texture.These soils have a slow rate of water transmission. Group D. Soils having a very slow infiltration rate (high runoff potential)when thoroughly wet. These consist chiefly of clays that have a high shrink-swell • potential, soils that have a high water table, soils that have a claypan or clay layer at or near the surface, and soils that are shallow over nearly impervious material. These soils have a very slow rate of water transmission. If a soil is assigned to a dual hydrologic group (ND, B/D, or C/D), the first letter is for drained areas and the second is for undrained areas. Surface runoff refers to the loss of water from an area by flow over the land surface. Surface runoff classes are based on slope, climate, and vegetative cover. The concept indicates relative runoff for very specific conditions. It is assumed that the surface of the soil is bare and that the retention of surface water resulting from irregularities in the ground surface is minimal. The classes are negligible, very low, low, medium, high, and very high. The months in the table indicate the portion of the year in which a water table, ponding, and/or flooding is most likely to be a concern. Water table refers to a saturated zone in the soil.The water features table indicates, by month, depth to the top(upper limit)and base(lower limit)of the saturated zone in most years. Estimates of the upper and lower limits are based mainly on observations of the water table at selected sites and on evidence of a saturated zone, namely grayish colors or mottles (redoximorphic features) in the soil. A saturated zone that lasts for less than a month is not considered a water table. • USDA Natural Resources Web Soil Survey 12/21/2009 a Conservation Service National Cooperative Soil Survey Page 1 of 4 Water Features—Weld County,Colorado, Southern Part Weiss USR Permit Water Features Map • Ponding is standing water in a closed depression. Unless a drainage system is installed, the water is removed only by percolation, transpiration, or evaporation. The table indicates surface water depth and the duration and frequency of ponding. Duration is expressed as very brief if less than 2 days, brief if 2 to 7 days, long if 7 to 30 days, and very long if more than 30 days. Frequency is expressed as none, rare, occasional, and frequent. None means that ponding is not probable; rare that it is unlikely but possible under unusual weather conditions(the chance of ponding is nearly 0 percent to 5 percent in any year); occasional that it occurs, on the average, once or less in 2 years (the chance of ponding is 5 to 50 percent in any year); and frequent that it occurs, on the average, more than once in 2 years (the chance of ponding is more than 50 percent in any year). Flooding is the temporary inundation of an area caused by overflowing streams, by runoff from adjacent slopes, or by tides. Water standing for short periods after rainfall or snowmelt is not considered flooding, and water standing in swamps and marshes is considered ponding rather than flooding. Duration and frequency are estimated. Duration is expressed as extremely brief if 0.1 hour to 4 hours, very brief if 4 hours to 2 days, brief if 2 to 7 days, long if 7 to 30 days, and very long if more than 30 days. Frequency is expressed as none, very rare, rare, occasional, frequent, and very frequent. None means that flooding is not probable; very rare that it is very unlikely but possible under extremely unusual weather conditions (the chance of flooding is less than 1 percent in any year); rare that it is unlikely but possible under unusual weather conditions (the chance of flooding is 1 to 5 percent in any year); occasional that it occurs infrequently under normal weather conditions (the chance of flooding is 5 to 50 percent in any year); frequent that it is likely to occur often under normal weather conditions(the chance • of flooding is more than 50 percent in any year but is less than 50 percent in all months in any year); and very frequent that it is likely to occur very often under normal weather conditions (the chance of flooding is more than 50 percent in all months of any year). The information is based on evidence in the soil profile, namely thin strata of gravel, sand, silt, or clay deposited by floodwater; irregular decrease in organic matter content with increasing depth; and little or no horizon development. Also considered are local information about the extent and levels of flooding and the relation of each soil on the landscape to historic floods. Information on the extent of flooding based on soil data is less specific than that provided by detailed engineering surveys that delineate flood-prone areas at specific flood frequency levels. • USDA Natural Resources Web Soil Survey 12/21/2009 Conservation Service National Cooperative Soil Survey Page 2 of 4 glikWater Featueld County,Colorado, Southern Part • Weiss USR Permit Weatures Map Report—Water Features Water Features—Weld County,Colorado,Southern Part Map unit symbol and soil Hydrologic Surface Month Water table Ponding Flooding name group runoff Upper limit Lower limit Surface Duration Frequency Duration Frequency depth Ft Ft Ft 35—Loup-Boel loamy sands, • 0 to 3 percent slopes Loup D Very high March 0.0-1.5 >6.0 — — None — None D Very high April 0.0-1.5 >6.0 — — None — None D Very high May 0.0-1.5 >6.0 — — None — None Boel A _ Very low January 1.5-3.0 I>6.0 — — I None — INone 1 ----- _... _.---- - —_—_ _--_ --'-A Very low February 1.5-3.0 >6.0 — — 'None — None A Very low I March 1.5-3.0 :.>6.0 — None — None I A _..._. _. •Very low April 1.5-3.0 >6.0 — None — None I A Very low I May 1.5-3.0 --_ >6.0 — — None - None November 1.5-3.0 >6.0 A Very low — None — J None A Very low December 1.5-3.0 I>6.0 — I— None — I None 44—Olney loamy sand,1 to 3 percent slopes • Olney B Low Jan-Dec — — — — None — — 45—Olney loamy sand,3 to 5 percent slopes Olney B Low Jan-Dec — — — — None — — 47—Olney fine sandy loam,1 to 3 percent slopes Olney B Low Jan-Dec — — — — None — — USDA Natural Resources Web Soil Survey 12/21/2009 Conservation Service National Cooperative Soil Survey Page 3 of 4 ilkWater Featueld County,Colorado, Southern Part II Weiss USR Permit Weatures Map Water Features—Weld County,Colorado,Southern Part Map unit symbol and soil Hydrologic Surface Month Water table Ponding Flooding name group runoff Upper limit Lower limit Surface Duration Frequency Duration Frequency depth Ft Ft Ft 56—Renohill clay loam,0 to 3 percent slopes Renohill C Low Jan-Dec — — — — None — — 57—Renohill clay loam,3 to • 9 percent slopes Renohill C Medium Jan-Dec — — — — None — — 64—Thedalund loam, 1 to 3 percent slopes Thedalund C Low Jan-Dec — — — — None — — 65—Thedalund loam, 3 to 9 percent slopes Thedalund C Medium Jan-Dec — — — — None — — 69—Valent sand,0 to 3 percent slopes Valent A Very low Jan-Dec — — — — None — — 70—Valent sand,3 to 9 percent slopes Valent A Low Jan-Dec — — — — None — — 73—Vona loamy sand,3 to 5 • percent slopes Vona B Very low Jan-Dec — — — — None — — Data Source Information Soil Survey Area: Weld County, Colorado, Southern Part Survey Area Data: Version 11,Aug 27, 2009 USDA Natural Resources Web Soil Survey 12/21/2009 a Conservation Service National Cooperative Soil Survey Page 4 of 4 Hello
