A complete list is <br />available in Appendix C that could potentially be in the watershed. <br /> <br />Wetlands <br /> <br />Many wetlands in the watershed are located along ditches, drains, and <br />the Arkansas River bottom. These wetlands are primarily Types 5 and 6 <br />(Shaw and Fredine, Circular 39, 1956); or PFO (palustrine forested), <br />R40W (riverine, intermittent, open water), and R20W (the Arkansas <br />River) (Cowardin, 1979). Irrigated fields also contain a small acreage <br />of wetlands caused by seeps and inefficient water management practices. <br />These wetlands are generally Type 1 (Circular 39) or PEM (palustrine <br />emergent). The project may result in loss or reduction in size of <br />irrigation induced wetlands in irrigated fields. Estimated acreage of <br />wetlands in the watershed are: <br /> <br />Type I <br />Type III <br />Type V <br />Type VI <br /> <br />90 Acs. <br />844 Acs. <br />73 Acs. <br />2300 Acs. <br /> <br />(PEM) <br />(PEM) <br />(POW) <br />(PFO, R20W, R40W) <br /> <br />These acreages were measured off the 1975 NWI (National Wetland <br />Inventory, USFWS) and compared with NRCS wetland inventory maps from <br />1990. The USF&WS acreage estimate exceeded. the NRCS inventory acreage, <br />therefore NRCS chose to agree on the higher acreage estimate. The <br />actual acres estimated to be affected were adjusted to account for <br />project participation. There will be no net losses of values of <br />wetlands due to project action. Mitigation actions will compensate for <br />wetland losses (see alternative "Effects" sections). <br /> <br />Archeoloav and Historic <br /> <br />The Indians of the plains occupied the project area, but apparently <br />left few traces. Conversion of the short-grass plains to cropland has <br />destroyed most surface vestiges of their past occupancy through various <br />cultivation practices. <br /> <br />12 <br />
