<br />. <br /> <br />. <br /> <br />i: <br /> <br />N' <br />o <br />w <br />w <br /> <br />Under the ACP Program, ASCS received 239 individual requests in 1982. Of <br />these, SCS serviced 228 with 185 completing one or more practices. Since <br />1979, over 1,400 separate requests for cost-share assistance have been <br />received with nearly 900 participants actually completing an irrigation water <br />management and salinity control practice. While the project relies heaVily on <br />annual ACP requests and practices, there have been 12 LTA's on 2,222 acres <br />developed since 1979. Two LXA contracts on 135 acres were completed in 1982. <br />The SCS has also assisted in the development of 48 IWM plans on 1,352 acres in <br />1982, bringing the total number of IWM plans to 195 on 5,473 acres. , Actual <br />IWM/salinity control practices applied in 1982 and cumulative to date <br />accomplishments are presented in Table IV-2. <br /> <br />i <br /> <br />Table IV-2 <br /> <br />Grand Valley Irrigation Water Managment <br />& Salinity Control Practices Applied <br /> <br />Practices <br /> <br />Unit <br /> <br />- 1982 1/ <br /> <br />Cumulative <br /> <br />Off-farm Related Laterals <br /> <br />Pipeline <br /> <br />Ft. <br /> <br />35,672 <br />1,607 <br /> <br />136,518 <br />56,241 <br /> <br />Ditch Lining <br /> <br />Ft. <br /> <br />Structures <br /> <br />No. <br /> <br />40 <br /> <br />107 <br /> <br />Onfarm Improvements <br /> <br />Pipeline <br /> <br />Ft. 68,213 219,284 <br />Ft. 37,750 127,252 <br />Ft. 43,490 114,945 <br />Ac. 343 1,782 <br />No. 50 130 <br />No. 8 <br /> <br />Ditch Lining <br /> <br />Gated Pipe <br /> <br />Land Leveling <br /> <br />Structures <br /> <br />Drip/Sprinkler Systems <br /> <br />1.1 1982 Fiscal Year <br /> <br />The cumulative impacts of these practices and improved irrigation water <br />management represent a 3,555 acre feet reduction in deep percolation per year <br />with an equivalent salt load reduction of 17,700 tons per year. This salt <br />load reduction translates into a 1.84 mg/1 reduction in salinity <br />concentrations at Imperial Dam. <br /> <br />15 <br />
