0560 <br />also contributes to the local economy. Waterfowl populations may begin , <br />to be impacted by the accumulation of selenium in the ecological <br />system. The Arkansas River fisheries will also be impacted by selenium ' <br />concentrations. These facets of the local economy will be negatively <br />effected by the existing water quality problems. The social <br />implications are that some people may choose to move out of the area <br />due to the water quality problems and continued loss of income to the ' <br />economy of the area. The known cultural resources in the area will not <br />be impacted. <br />Alternative 2. Management Measures ' <br />8,900 Acres of nutrient management practices, <br />2,900 Acres of conservation tillage, crop residue use, and <br />polyacrylamides, ' <br />8,900 Acres of irrigation water management, <br />8,900 Acres of pest management. <br />Total Project cost is $616,000. ' <br />Components - <br />8,900 Acres of nutrient management practices, <br />' <br />2,900 Acres of crop residue use, conservation tillage, and <br />polyacrylamides, <br />8,900 Acres of irrigation water management, <br />' <br />8,900 Acres of pest management. <br />Effects <br />Implementation of management practices will more effectively use <br />irrigation water by reducing deep percolation. Reduced irrigation <br />induced erosion, sediment movement, and improved water quality of the <br />surface and ground water will also occur. The overall effect is an <br />, <br />improvement in the water quality of return flows and groundwater within <br />the watershed. <br />' <br />The management practices associated with this alternative would <br />slightly improve wildlife and fish habitat by reducing sedimentation <br />and deep percolation. The additional ground cover along with water <br />management would reduce the amount of irrigation induced erosion <br />' <br />occurring. This would decrease the amount of sediment available for <br />transport through the hydrologic system. The amount of contaminants <br />entering the ecological system from agriculture would be reduced by <br />utilizing this alternative. The impact of agriculture on endangered <br />species would be lessened due to improved water quality and <br />conservation. <br />, <br />The social and economic conditions would improve as improved water <br />application allows the agricultural producers to better meet crop needs <br />and contribute to the goal of improved water quality. The protection <br />of the soil resource base from irrigation induced erosion will also <br />have a positive effect on the local economy. The environmental , <br />conditions related to fish and wildlife will show a slight improvement <br />28 1 <br />
