<br />5. Coordinate investigations in diffuse source areas with appropriate <br />agencies to formulate and implement salinity control plans. <br /> <br />Soil Conservation Service planning activities are authorized under <br />PL-83-566 with added authority under PL-93-320, Section 203 (a) (l) and <br />(b) ell. Under the Title II Memorandum of Agreement between WPRS and <br />SCS, the Soil Conservation Service agrees to: <br /> <br />1. <br /> <br />Support the IMS program by providing (a) technical assistance and <br />(b) soil survey data on water management measures. This will be <br />accomplished with ongoing programs with conservation districts. <br /> <br />Investigate and develop plans for feasible alternatives to imple- <br />ment onfarm programs to reduce deep percolation by improving irri- <br />gation efficiency. Alternative plans will be supplied to WPRS for <br />inclusion in their plans for the area. <br /> <br />Arrange for Science and Education Administration - Agricultural <br />Research (SEA-AR) or other appropriate USDA agencies to establish <br />and conduct research and demonstration projects to advance the <br />technology available for designing onfarm systems to increase <br />irrigation efficiencies and control salinity from diffuse sources. <br /> <br />Participate in the activities of local salinity control coordinat- <br />ing entities and arrange for educational programs through the <br />Cooperative Extension Service. <br /> <br />2. <br /> <br />3. <br /> <br />4. <br /> <br />5. <br /> <br />Appraise the sa1 inity accretion emanating from within the diffuse <br />source areas located on private lands and participate in the <br />development of coordinated programs for these lands and the adjoin- <br />ing or included National Resource lands in cooperation with appro- <br />priate agencies of the USDI. <br /> <br />In cooperation with research and operational entities concerned <br />with water quality conditions, undertake a comprehensive evaluation <br />of agricultural water use and erosion as they relate to salinity <br />control within the Colorado River Basin and report thereon. <br /> <br />The Memorandum of Agreement was ammended August 23, 1979 to include SCS <br />study and installation of lateral improvements under ongoing USDA programs. <br /> <br />Objective anE Scope <br /> <br />6. <br /> <br />7. <br /> <br />The objectives of the USDA's participation in the salinity control <br />studies in the Virgin River Unit of the Lower Colorado River Basin are: <br /> <br />1. To determine the contribution of salt and sediment loading from <br />irrigated land and related upland watershed areas. <br /> <br />002682 <br /> <br />2 <br />
