<br />through the on-going conservation operations technical <br /> <br />assistance programs. <br /> <br />While these existing USDA program <br /> <br />o <br />~ authorities have l)Uilt-in restrictions and limitations, and <br />o <br />~ even though existing authorities are not tailored to salinity <br /> <br />control and irrigation water management, USDA has managed to <br /> <br />make reasonably good progress and achieve some meaningful <br /> <br />level of on-the-land salinity control accomplishments. <br />In the Grand Valley, Colorado SCS personnel estimate the <br />1981 onfarm salt load reduction impacts at approximately <br />13,500 tons reduction (equivalent to 1.4 mg/l reduction in <br />salinity concentration at Imperial Dam). Utah SCS personnel <br />estimate a salt load reduction of 12,000 tons for the Uinta <br /> <br />Basin. <br /> <br />When fully implemented, the Grand Valley project <br /> <br />(l30,000 ton annual salt load reduction) and Uinta Basin <br />(76,000 ton annual reduction) should result in a 23.0 mg/l <br /> <br />reduction of salinity levels at Imperial Dam. <br /> <br />~~~~~E~h_~g~_~~~~~!i~g: Additional USDA emphasis by <br />Agricultural Research Service (ARS) is also contributing to <br /> <br />improved technology and data on both water management prac- <br /> <br />tices and salinity control impacts. With support from the <br /> <br />Snake River Conservation Research Center and the Agricultural <br /> <br />Engineering Research Center, Ft. Collins, ARS has worked <br /> <br />with and assisted farmers in the Uinta Basin and Grand <br /> <br />Valley. The major efforts have been directed towards a <br /> <br />number of methods and types of improvements including; auto- <br /> <br />-18- <br />
