<br />adverse environmental impact has been identified at this stage of the environmental <br /> <br />'. <br /> <br />. t ~ <br />evaluation process. The US Fish and Wildlife Service (F&WS), US Geological SOrVey. <br />(USGS), the Colorado State Historic Preservation Officer (SHPO), and the Colorado <br /> <br />Division of Wildlife (DOW) have been and will continue to be conWJ.ltaeted. <br /> <br />Purposes to be served by the project are agricultural water management and watershed <br /> <br />protection. Specifically, this project has been formulated to improve both surface and <br /> <br />groundwater quality, reduce irrigation induced erosion to acceptable levels, and more <br /> <br />effectively conserve and use available water supplies by improving on:-farm irrigation <br /> <br />water management thus reducing deep percolation. Irrigation induced erosion will be <br /> <br />reduced in the treatment area on 10,000 acres now eroding at 2-7 times the maximum <br /> <br />rate iilllowabl~Aeeessary to maintain the productive capacity of the soil resource. Poor <br /> <br />water quality from nutrients, heavy metals and salts in wells and drains will be improved <br /> <br />in the watershed as well as in the Arkansas River. Better on farm irrigation water <br /> <br />application will occur on 31,000 acres. These efforts will helD move i,WQated aaric\,llm <br /> <br />closer to tii'ina able to achieve the irriaatlon eff~ctiveness which existed in the .19508. <br /> <br />The Recommended Plan (RP) includes ditch lining, pipe lines, gated pipe, surge, <br /> <br />water control structures, appurtenant structure~ leveling, IWM, nutrient and pest <br /> <br /> <br />management, wetland mitigation practices, polyacrylamide, residue management, and <br /> <br /> <br />livestock waste facilities. The estimated cost of the recommended plan alternative is <br /> <br />$8,765,500 with $4,952,300 in PL-566 costs. <br /> <br />2aHS <br />
