. . . o ..", CT.l I-' The Farmington District has entered into an interagency agreement with the Bureau of Reclamation and Western Colorado Area Office, Southern Division in Durango. Colorado. BLM transferred $50.000 in salinity funds to BaR for plugging saline water wells in the Aneth, Utah, area. The money is targeted for the Aneth Day School Well, No. N35. The well was reportedly dynamited. This was one of the wells that was identified in a presentation by David Naftz to the Salinity Forum in 1996. There are a lot of unknowns about this well. and an attempt will be made to plug it. Any leftover money will be used for plugging other saline wells in the Aneth area. BaR administers the contract, and BLM develops the plugging requirements and provides technical expertise. Water quality measurements were taken in April 1997 and indicated 8800 ppm TDS for approximately 60 gpm of flow. Burlington Resources has agreed to re-enter and plug the Navajo lA well. This well is also identified in the Naftz (1996) report (known as the N46). SoutWand Royalty drilled the well in 1963, and Burlington Resources subsequently acquired the leases. Water quality measurements conducted on this well in April 1997 indicated 5900 ppm TDS for a flow of approximately 60 gpm. Within the Socorro Resource Area, erosion control structures were installed in the upper watershed area of the Little Colorado River in the Largo-Agua Fria Watershed on Escodida Creek (90 structures) and in Little Blanco Canyon of the Fence Lake watershed (2 structures). Also in Socorro, pipelines were installed for water improvements to implement Best Management Practices related to two grazing allotment plans in the upper Little Colorado River watershed. Nevada During FY 97, four additional detention basins were completed under the Clark County Regional Flood Control Master Plan, three in the Las Vegas area, and one near Laughlin, Nevada. Although the primary objective of these facilities is to minimize the loss of life and property, their installation has resulted in an undetermined reduction of dissolved solids entering the Las Vegas Wash and Lake Mead. One hundred forty-five burros were removed from the Gold Butte Herd Management Area in FY 97 under the FY 95 National Park Service plan to reduce the number of animals at Lake Mead by 82 percent. Some reduction in salt loading to Lake Mead is anticipated from the reduction. During FY 97, grazing restrictions imposed by the Desert Tortoise Biological Opinions of 1991 and 1994 remained in place. These restrictions within the Las Vegas District affect 17 grazing allotments containing 141,000 acres of highly saline soils tributary to the Colorado Grazing reductions prescribed in FY 95 on the Wilson Creek Allotment remained in place during FY 97. The prescription will be reevaluated in FY 98. In FY 97, a tamarisk removal project was completed on 6 acres in Hiko Wash, located approximately 6 miles above the Colorado River. Also during FY 97, the Virgin River 13 ~ ,p,:~c,.", ".,",,, ,,,ilt~~~
