~ o W extensive development, the Vernal District has required the operator to complete mitigation o measures for access road, waterline, and wellpad impacts. Watershect mitigation measures, all paid for by the field Qperators, saved approximately 60 tons of salt. The measures included erosion control structures, water bars, reseeding, hydro mulching, and working with the BLM staff on the proper road and wellpad construction. In the Cedar City District, the 1996 Skutumpah 450 acre burn is being reseeded withParia River salt savings anticipated. Extensive fire rehabilitation was accomplished in the Dixie Resource area, as well as a 700 acre treatmentfor sage encroachment of an old seeding on Little Creek Mountain, tributary to the Virgin River. The $16,000 .tebuthiuron treatment cost was shared with the livestock permittee. The Muddy Creek PJ ch'aining (Natural Resources Conservation Service) is underway in the Kanab Area, and currently involves 500 acres of public land. Also in the Paria Drainage of the Escalante Resource Area, willow and other riparian' plantings have been supported by volunteers and BiM funding at Henryville Creek. ,{ , :} ~~ Ii ~ ~1 }~ . ..;: "'~ <, ;~ ll,~ f~ :;\' d :j ';3 ;.:1 ::~ \t :~ ~~:i Richfield District constructed three silt-free reservoirs in Garfield County, tributary to Hansen CreekILake Powell using range improvement and livestock permittee funds. Much of the BLM's FY-96 field activities in the Hanksville Resource Area indirectly benefit salt savings In the Fremont ,andDirty Devil watersheds. " In the Moab District, a fence was constructed to rest a riparian area adjacetlt to Grassy Trail Creek, saving 5 tons/year of salt through elimination of bank trampling and erosion. As a result of a 1995 road failure above the confluence of Dry Creek and Nine Mile Creek, a'salt loading event of 15 tons occurred into the Nine Mile Creek/Green River system. Recent road reconstruction by the Moab field office has stopped the continued cutting and leaching of salts from fresh marine' deposits, and stopped an estimated two tons of annual salt loading. The Walker F1atweIl is an abandoned coal exploration hole with artesian saline flow. Responsibility for the well was assumed'by the BLM. The uncontrolled flow has created a 15 by 40 foot wide gully or'500 feet length in saline deposits, and it yields 121 tonsofsaltper year. The Utah State Office will issue a request for bids to plug the well by the end of September, 1996 , ($50,000 cost-estimate). Wyoming Within the Muddy Creek watershed of the Great Divide Resource Area, the BLM and the Little Snake River Conservation District cooperated to accomplish salinity monitoring objectives, using conventional and electronic equipment. The surface water gage at Red Creek was maintained and operated to continue monitoring water quality improvements from implementation of the Red Creek Management Plan treatment and rehabilitation actions. A total of six water quality monitoring stations were operated in FY -96 on public lands of the Basin.

Preliminary work (site inspection, survey/design and NEPA compliance) was also begun on three similar Rawlins District facilities. Red osier dogwood, currant species, and various willow were planted in parts of Littlefield Creek and Upper Muddy Creek. J ,.:;~ :~ _~1 "4 ;~ti 17 --
