Lamar Gravel Wetland Delineation Ecological Resource Consultants,Inc. <br /> land, bordered by irrigation ditches. At its closest point,the Arkansas River occurs approximately <br /> 800 feet north of the Study Area. <br /> The Prowers County Soil Survey (USDA SWS, 2007) maps the soils within the Study Area as <br /> Rocky Ford clay loam and Las clay loam. Both Rocky Ford clay loam and Las clay loam are <br /> listed as hydric soils of Colorado(NRCS,2007). <br /> Figure 2.

Three general <br /> environmental parameters define a wetland. These parameters consist of the presence of <br /> hydrophytic vegetation, hydric soils, and wetland hydrology. Areas that do not meet any one of <br /> the wetland parameters (hydrophytic vegetation, hydric soils and/or wetland hydrology) were <br /> classified as a non-wetland and mapped as such. In addition, waters of the U.S. are defined as <br /> areas that "include essentially all surface waters such as rivers, streams and their tributaries, all <br /> wetlands adjacent to these waters, and all ponds, lakes and reservoirs". Waters of the U.S. are <br /> further defined by the ordinary high water mark(OHWM). The OHWM is characterized as"the <br /> line on the shores established by the fluctuations of water and indicated by physical <br /> characteristics such as: a clear natural line impressed on the bank, shelving, changes in the <br /> character of the soil, wetland vegetation, the presence of litter and debris, and other appropriate <br /> 3 <br />
