<br />ProRram AccomPlishments and Effects <br /> <br />tv <br />>/.7>. <br />':.4 <br />ell <br /> <br />Onfarm and ,off-farm lateral improvements in Grand Valley have ,been accom~ <br />plished primarily through the annu~l practice cost-shareprovisio~ of the ACP <br />program in ASCS. ,Onfarm pipeline and ditch lining for 1984~as 116,433.feet <br />and 26,249 feet respectively. Total onfarm pipeline and ditch lining <br />accomplishments ,thus far are approximately 112 miles, of pille lines and 36 miles" <br />of ,ditch lining. Combined, ,these accomplishments rept;'esentabouj:. 22.4'Lofthe <br />total Grand Valley projects goals. <br /> <br />'. <br /> <br />Off-farm lateral improvements for 1984 consisted of 15,792 feet of pipeline <br />improvements. Total off-farm lateral accomplishments for the project are <br />,32.8,miles ,of pipelines and 10.8 miles, of ditch lining, representing ,22.9" of <br />the overall project goals. , <br /> <br />Onfarm seepage 'or deep percolation reductions are estimated"tll l:le 3,378 acre <br />feet per year for an average salt load reduction of17,027,tonsper year. <br />Off-farm lateral seepage reductions are 2047 acre feet per year for 10,295 tons <br />of salt load reductions per year. Total seepage/deep percolation reductions <br />are 5,425 acre feet per year fora 27,322 tons per year salt load reduction. <br /> <br />UINTA BASIN <br /> <br />,'IrriRation System I\lll)rovements <br /> <br />Prior to implementation of the selected plan a total of 35,100 aeres had <br />received treatment through improved irrigation systems. An estimated 10,200 <br />acres were improved with sprinkler systems While 24,900, acres had received <br />improved surface systems. Portions of these improvements were installed with <br />assista~ce through, the regular ACP cost, share program~ <br /> <br />Crop yields' have also been reduced in areas with poor drainage and <br />salt-toxicity problems. , Decreasing yields of alfalfa and small grains are <br />also evident in areas that haVe 'been continually over irrigated. This has <br />resulted 'in', a shift ,to more water and salt,..tolerantplants,.. <br /> <br />ProRramAccomplishments and Effects <br /> <br />A total'of $7,623,017 in ACP-Salinityfunding has been obligated, from 1980 to <br />1984 on 20,573 acres through Long Term Agreements. In addition to this, <br />$1,339,722 ,was obligated for annual practices. These improvements included <br />both sprinkler and surface systems. DUring the past three irrigation seasons, <br />irrigation water management has been applied to a total of 10,929 acres of <br />farmland. Salt reduction of 12,900 tons (6,550 acre feet of reduced <br />percolation) ,has resulted from application of these structural and management <br />practices. <br /> <br />-18- <br />
