<br />. <br /> <br />. <br /> <br />Shortage of late season water supply can be solved by constructing <br /> <br />additional storage reservoirs. Choosing between more reservoirs and ditch <br /> <br />lining to reduce seepage will be based on costs and a need for water greater <br /> <br />than the quantity saved through reduced ditch seepage. <br /> <br />A single objective solution for salinity control could be accomplished <br /> <br />by diverting highly saline return flows into evaporation ponds. <br /> <br />Estimated Costs <br /> <br />Unit costs for installing works of improvement, based on similar <br /> <br />improvements recently installed, are estimated to be $500 per irrigated acre <br /> <br />for onfarm improvements and $300 per irrigated acre served for off-farm <br /> <br />conveyance system improvements. <br /> <br />It is estimated that 1,600 acres of irrigated land would be improved <br /> <br />under the Watershed Project. The federal cost share is estimated to be 50 <br /> <br />percent. Therefore, project costs are estimated to be: <br /> <br /> Cost Estimate <br />Item Local Federal TotaL <br />Onfarm progr= 1,900,000 1,900,000 3,800,000 <br />Off-Farm Program 1,150,000 1,150,000 2,300,000 <br />Operation & Maintenance l/ 60,000 60,000 <br />Project Administration ~ 10,000 1,050,000 1,060,000 <br />Engineering Assistance 1/ 850,000 850,000 " <br /> 3,120,000 4,950,000 8,070,000 <br /> <br />1/ Estimated to be about 1 percent of construction cost. <br />2/ Estimated to be about 17 percent of construction cost. <br />1/ Estimated to be about 14 percent of construction cost. <br /> <br />002222 <br /> <br />4 <br /> <br />x <br />
