Improvement projects involved mostlY:' <br />erosion control structures constructed by the energy companies engaged in field development. <br />Erosion cOntrol work was also done in the Natural Buttes Gas Field. <br /> <br />,~ <br /> <br />Other salipity projects in FY -98 included greasewood control in the Three Corners area, <br />sagebrush' and pinyon-juniper control in the Pariette watershed, and sagebrush and greasweood <br />control in.the Bitter Creek drainage in the Bookcliffs. <br /> <br />Wyoming <br /> <br />During FY -98, salinity control efforts in Wyoming have focused heavily on tributaries of the <br />Little Snake River watershed and on tributaries to the Green River watershed within the <br />Kemmere~ RA. These efforts, mostly within the Rawlins District, accounted for roughly 600 <br />tons per year of salt savings during FY-98. <br /> <br />The main tributaries to the Little Snake River are Littlefield, Loco, McKinney, Muddy, and <br />Savery Cr~eks. All but Savery Creek have been identified as Water Quality Limited Segments <br />by the Wy,oming Department of Environmental Quality. Salinity reductions within the Little <br />Snake River watershed accounted for roughly 335 tons per year of the 600 tons per year <br />reported by Wyoming in FY-98. <br /> <br />',," <br /> <br />The Coonlinated Resource Management (CRM) group established for Muddy Creek in 1996 <br />continued to be active in 1998. focusing on integrated watershed approaches to water quality <br />and salinity issues. A similar group is being considered for the Loco and Savery Creek <br />tributaries' to the Little Snake River. <br /> <br />, <br />:1' <br /> <br />. <br /> <br />Working Qlosely with the CRM group, BLM is monitoring water quality in Littlefield and <br />McKinney Creeks and at two stations on the main stem of Muddy Creek. A new water quality <br />monitoring program was also implemented on Savery Creek during FY.98. <br /> <br />'", <br />"~ <br /> <br />';;., <br />,> <br /> <br />BLM has implemented riparian and grazing management systems on Muddy Creek that are <br />. . <br />designed to improve riparian vegetative vigor, reduce salt loading, and improve overall water <br />quality. <br /> <br />;} <br />, ',~ <br /> <br />Work is also underway at the close of FY.98 to modify and improve the George Dew <br />watersprel(ders and dikes on Muddy Creek. The improvements will increase the effective life of <br />the structures, further stabilize the channel of Muddy Creek, and reduce erosion and salinity <br />inputs into the main stem of Muddy Creek. <br /> <br />j1, <br />'j <br />'i <br />'j <br /> <br />. ~ <br />. <br /> <br />Salinity reductions in the Kemmerer RA in FY-98 were achieved primarily through range <br />improvements and improved grazing management practices on specific grazing allotments. <br />Activities within the RA accounted for approximately 260 of the 600 tons per year reduction in <br />salinity reported by Wyoming. Tributaries to the Green River include Ham's Fork, Horse <br />Creek, Little Muddy Creek, Muddy Creek. Ryckman Creek, and Willow Creek. Kemmerer <br />RA salinitY control measures during FY-98 concentrated on the Willow Creek/Black's Fork <br />watershedithe Cumberland/Uinta CRM area (east side of the Bear River Divide) and the Mox~ <br /> <br />:i <br />"t <br />.~ <br /> <br />18 <br /> <br />
