Under the plan about 21,300 acres <br />would be irrigated with gravity-pressure sprinkler systems, 7,300 acres with <br />pump pressure sprinkler systems, and 1,300 acres with improved surface <br />irrigation systems. <br /> <br />Combined Agency Planning Activities <br /> <br />In March 1986 Reclamation and the SCS jointly prepared a report for <br />consideration by the salinity Forum Work Group. The report summarized a <br />appraisal-level investigation of gravity sprinkler irrigation systems for the <br />Ferron and Cottonwood Creek areas. Under this plan all off-farm conveyance <br />facilities which consist almost entirely of pressurized pipelines would be <br />constructed as a Reclamation project. All on-farm improvements would be <br />constructed as an SCS project and would require cost-sharing by local <br />beneficiaries. The March 1986 report indicated that as a result of <br />implementing this plan in the Ferron and Cottonwood Creek areas salt loading <br />could be reduced by 52,322 tons per year at an average cost of $70 per ton. <br /> <br />III-2 <br /> <br />i';"'61' <br />lo ,) \.' 1.. <br />
