<br />..... <br />w <br />W <br />U1 <br /> <br />Installation of salinity reduction and <br />voluntary wildlife habitat practices <br />continued at a rapid pace even during this <br />water shortage period. During the year, <br />83 sprinkler systems and 60 miles of <br />pipeline were installed to reduce deep <br />percolation and seepage from earth ditches. <br />Salinity reduction practices were installed <br />on surface irrigation systems and te<:hnical <br />assistance on irrigation water management <br />provided to program participants, The <br />annual salt load reduction achieved since <br />the program was started is 36,414 tons per <br />year, During the year $1,34 million CRSC <br />and $1.0 million ACP cost-share funds were <br />paid out to participants for the installation <br />of salinity reduction and wildlife habitat <br />practices. <br /> <br />During the year, program participants <br />installed a variety of wildlife habitat <br />practices including ponds, shallow water <br />areas, wildlife habitat plantings, and <br />fencing. One contract was devoted solely to <br />wildlife practices, For fiscal year 1990, <br />60 percent of the applications for salinity <br />contracts include wildlife practices and <br />seven applications are solely for the <br />installation of wildlife habitat practices, <br />Wetland and upland habitat management <br />achieved under the salinity control program <br />now totals 4,780 acres. <br /> <br />Monitoring and evaluation activities indi- <br />cate that the average irrigation efficiency <br />being achieved is 65 percent, In general, <br />the labor required for irrigating with the <br />installed systems decreased and the yields <br />increased when compared to the original <br />systems. <br /> <br />A full-time Cooperative Extension Service <br />Agent provides assistance to the Uinta <br /> <br />Basin CRSC program. During the year, the <br />Cooperative Extension Service completed <br />various information/education activities <br />which included updating the Uinta Basin <br />CRSC video, preparing four new infor- <br />mation bulletins, conducting a number of <br />salinity control tours and seminars, and <br />installing several demonstration plots. <br /> <br />Monitoring and Evaluation <br /> <br />Reclamation <br /> <br />Reclamation has a continuing monitoring <br />program of the Las Vegas Wash Unit, <br />Nevada, This consists of quarterly <br />collection and analysis of water samples <br />from selected locations in the Wash. Water <br />quality data will be evaluated and reported <br />annually to permit identification and <br />tracking of any trends in water quality, <br /> <br />USDA <br /> <br />USDA monitoring and evaluation (M&E) <br />plans have been prepared for the USDA <br />Grand Valley, Uinta Basin, Lower <br />Gunnison, McElmo Creek, and Moapa <br />Valley Projects. In the Grand Valley and <br />Uinta Basin, the M&E activities have been <br />underway for over 5 years. Annual reports <br />have been prepared for the Uinta Basin and <br />Grand Valley projects, These reports are <br />providing valuable information as more <br />information is analyzed and techniques are <br />refined. The M&E activities in the other <br />projects are still in the early stages of <br />implementation. <br /> <br />11 <br />
