Populations of wild salmon and steelhead in the Middle Fork of the Salmon River are at historical lows. Until passage and flow problems associated with Columbia River dams are corrected to reduce mortalities of migrating smolts, continuance of habitat enhancements that decrease sediment loads, increase vegetative cover, remove passage barriers, and provide habitat diversity is imperative to maintain surviving populations of these specially adapted fish. In 1987-1988, 4.3 miles of fence was constructed establishing a riparian livestock exclosure. One end-gap and two water-crossing corridors were constructed in 1989 to complete the fence system. Areas within the exclosure have been fertilized to promote tree and shrub root growth and meadow recovery. A stream crossing ford was stabilized with angular cobble. Streambank stabilization/habitat cover work was completed at three sites and three additional habitat structures were placed. Extensive inventories were completed to identify habitat available to anadromous fish. Streambank stabilization work was limited to extremely unstable banks, minimizing radical alterations to an active stream channel. Enhancement activities will improve spawning, incubation, and rearing habitat for wild populations of steelhead trout and chinook salmon. Anadromous species population increases resulting from these enhancement activities will provide partial compensation for downstream losses resulting from hydroelectric developments on the Columbia River system. 10 refs., 11 figs., 5 tabs.
