<br />shar ing through long-term agreements (LTA's) or contracts. <br /> <br />l\:) <br />CJ1 <br />W <br />00 <br /> <br />Through 1986, ASCS has obligated $11,017,941 for 414 (260 <br /> <br />active) LTA's covering 31,718 acres. Major practices include <br /> <br />the improvements on both sprinkler and surface irrigation <br /> <br />systems. <br /> <br />Irrigation water management improvements to date <br /> <br />total 29,265 acres with 274 miles of pipelines installed. <br /> <br />As a result, SCS estimates the annual reduction in seepage <br /> <br />and deep percolation to be 23,300 acre-feet for an annual <br />salt load reduction of 21,527 tons. <br /> <br />USDA has published a report on the Big Sandy River Unit <br />that has undergone public review. The State of Wyoming <br /> <br />strongly supports the selected low-pressure sprinkler <br /> <br />alternative, as does the Forum. Concerns have been raised by <br /> <br />the U.S. Fish and Wildlife Service and the Environmental <br /> <br />Protection Agency over the potential loss of wetland habitat <br /> <br />and a small fishery resulting from improved onfarm irrigation <br /> <br />efficiencies achieved under the selected plan. The State has <br />requested Reclamation to refine the salt and water budget and <br />to look at selected lining of unlined segments of the canal <br /> <br />and lateral systems. <br />Reclamation selected a prefer red plan for the <br />Dirty Devil River Unit in 1985. The plan is to inject saline <br />water from the Hanksville South Salt Wash and Emery South <br />Salt Wash into injection wells about 3500 feet deep. <br />Planning has been temporarily suspended, at the request of <br />the State of Utah and supported by the Forum, to allow the <br /> <br />State of Utah to further explore the water rights issue. <br /> <br />-11- <br />
