Tenmile Creek is a 42 square mile tributary to the Snake River between Asotin Creek and Grande Ronde, and is almost exclusively held under private ownership.  Wild steelhead and rainbow/redband trout spawning and rearing was documented by WDFW in 2000 and 2002.  36 redds in 15.9 miles in 2000 and 29 redds in 7 miles were also documented in 2001 with an additional 23 resident rainbow/redband trout redds.

Couse Creek is a 24 square mile tributary to the Snake River between Tenmile Creek and the Grande Ronde.  It is also almost exclusively held under private ownership with wild steelhead and rainbow/redband trout spawning and rearing documented by WDFW.

The ACCD, in cooperation with co-managers and local landowners, has identified priority restoration projects and the need to continue to assess salmonid use of streams outside of Asotin Creek.  The CREP Program, independent of BPA, has been successful in working with landowners to protect riparian areas and implement upland BMPs to reduce erosion.  This initiative has gained momentum and is needed to continue to implement the Asotin Subbasin Plan, which has identified priority areas and actions for ESA listed streams within Asotin County.  Couse and Tenmile are protection areas as identified by the Asotin Subbasin Plan.

The objectives within the overall SOW are to continue to identify priority areas and actions for ESA listed streams and fish species within Asotin County 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 BMP's and livestock management and exclusion from adjacent streambanks and beds.

Current Work Elements (WE's), such as tree plantings, fencing, no-till direct seeding, and upland erosion and sedimentation control, meet these objectives by utilizing tree plantings and no-till direct seed to further reduce upland erosion and soil loss, sediment loading, and to increase 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.
