<br />O~~l~'lJ <br /> <br />Alternative Plans Considered: <br /> <br />1. Future without - no action <br />2. Management practices <br />3. Management practices plus enduring irrigation systems improvements. <br /> <br />Other Alternatives Considered, But Did Not Adequately Address Problems, <br />Included: <br /> <br />a. canal lining <br />b. change from surface systems to center pivots <br />c. purchase of irrigation rights from land owners <br /> <br />Project Purposes: <br /> <br />The primary purposes are: 1. Agricultural water management - reduce negative water <br />quality impacts to surface and groundwater, including the Arkansas River from <br />selenium, sediment, salts and nitrate loading and improve water application <br />effectiveness; and 2. Watershed protection - protect the soil resource base from <br />excessive irrigation induced erosion and sedimentation... These purposes are related to <br />achieving a condition which approaches that which existed prior to the Arkansas River <br />Compact. This will be accomplished with modernization of the on-farm irrigation <br />systems and methodologies. <br /> <br />Principal Project Measures: <br /> <br />It is expected that 250 long-term land treatment contracts will be written during the <br />project's life. Approximately 31,000 acres will be treated through project action. <br /> <br />Practices to be installed for this project action include: <br /> <br />. 31,000 acres with irrigation water management & nutrient management. <br />. 1,000 acres of pest management. <br />. 6,000 acres residue management. <br />. 190,000 ft. of ditch lining <br />. 310,000 ft. of pipelines <br />. 210,000 ft. of gated pipe <br />. 3,600 ac. of land leveling <br />. 240 water control structures <br />. 4,000 acres of polyacrylamides <br />. 80 Hydrants <br />. 400 alfalfa valves <br />. 25,600 ft. gated pipe for surge irrigation <br />. 80 surge valves <br />. 50 acres of wetland habitat development <br />. 3 feedlot pits <br />. 3 feedlot diversions <br />. 3 drip systems <br /> <br />3 <br />
