Asotin Creek, a tributary to the Snake River at Rm 145, drains approximately 325 square miles of Asotin and Garfield Counties.  Headwaters originate in the Blue Mountains (6,200 ft) and flow east into the Snake River (800 ft) at Asotin, WA.  Located in WRIA # 35, the highest priority WRIA in southeastern Washington according to WDFW's "At-Risk Stock Significance Map," Asotin Creek is part of the Governor's Snake River Salmon Recovery Region.

Asotin Creek remains an important Snake River tributary for anadromous salmonid production in Washington and has been given the distinction of a reserve for wild steelhead under current WDFW management policy.  Charley Creek, an upper tributary, historically has some of the highest densities of juvenile steelhead in southeastern Washington according to WDFW fisheries surveys.

ESA listed stocks of summer steelhead, bull trout and spring Chinook, along with resident rainbow trout, utilize the watershed.  Indigenous anadromous fish species most actively targeted for management are summer steelhead, bull trout, and spring Chinook salmon.  The goals for these species are to restore sustainable, naturally producing populations to support tribal and non-tribal harvest and cultural and economical practices while protecting the biological integrity and genetic diversity of these species in the watershed.  The broad general strategies used to achieve the habitat objectives include protecting and restoring prioritized habitat through the use of in-stream, riparian, and upland best management practices.

The Asotin Creek Model Watershed Plan (Plan) was printed in 1995.  It was the first BPA funded Model Watershed Plan completed in Washington that deals specifically with watershed restoration and protection focused on fish habitat restoration.  Anadromous salmonid production in Asotin Creek is affected by high summer stream temperatures, sediment deposition, turbidity, loss of riparian vegetation, and lack of suitable resting and rearing pool habitat as recognized by the Plan.  Decreasing stream water temperatures and increasing complex resting and rearing pools are goals identified in the Plan.  The work for this project is not only identified in the "Asotin Creek Model Watershed Plan", but can also be found in the "Asotin Creek Subbasin Plan" and the "Snake River Salmon Recovery Plan."

Without cooperation and partnerships at the local level this process will not be successful.  The objectives within the overall SOW are to continue to identify priority areas and actions for ESA listed streams and fish species within the Asotin Watershed and to provide habitat restoration and to further establish, protect, and improve overall water quality, riparian areas, and stream habitat.  Additional objectives are to continue to reduce soil erosion and instream sedimentation by stabilizing soils and streambanks with agricultural BMPs and livestock management and exclusion from adjacent streambanks and beds.

Current work elements, such as tree plantings, fencing, alternative water sources, and no-till direct seeding, meet these objectives by further reducing upland erosion and soil loss, sediment loading, and increasing riparian buffer establishment.  Riparian buffers also serve to reduce instream temperatures, provide direct soil stabilization and provide needed stream shading and habitat for fish redds and fry in the stream.  Fencing keeps livestock out of the streams, further protecting the streambanks, reducing in-stream sedimentation, and reducing fecal coliform levels.  Sediment basins serve to collect runoff and soil loss before leaving the site and before entering stream systems.  Basins hold the water and soil on-site, allowing the water to percolate back into the soil and overall water table where it is needed.
