xyarology <br />The USSCS Soil Survey of Lorimer County describes these soils as frequently <br />flooded for very brief durations between March and September. The depth to <br />seasonal high water is between 1.5 - 2.5 feet. <br />The wetlands on this parcel occur in a remnant stream channel. Although no stream <br />currently exists in the channel, it is apparent that the Swale still carries the majority <br />of runoff south to a culvert beneath County Rd. 36. The wetland areas appear as <br />depressions within the channel scars, and so are likely seasonally inundated or <br />saturated for extended periods during the growing season. In addition, a high <br />water table during much of the growing season may be sustained by the slow <br />permeability of the surface soil horizon and fibrous root systems. <br />Conclusions <br />In total, 0.95 acres ofjursdictional Waters of the US including wetlands exist on <br />the Wellington Downs sand and gravel pit site. Of this, 0.57 acres is juridictiona] <br />wetlands. These may best be described as alkaline wet meadow wetland <br />ecosystems. <br />Project Impacts <br />The sand and gravel mining operation will impact a total of 0.95 acres of <br />jursdictional Waters of the US including isolated wetlands. <br />Weninglon Downs Pil -Wetland Delineation Anderson k Company <br />T6N, R68W, S3, Lorimer County April 14, 1995 <br />
