The Asotin County Conservation District is sponsoring this restoration project to add more wood to sections of Charley Creek, North Fork Asotin Creek, and South Fork Asotin Creek. These creeks are in the Asotin Creek watershed approximately 6 miles south of Clarkston, WA and are part of an Intensively Monitored Watershed project (IMW). The goal of the project is to increase wood density, instream habitat complexity, and floodplain connection which will improve rearing and spawning conditions for wild summer run steelhead. This restoration project should also result in an increase in steelhead productivity and lead to greater understanding of how to improve the efficiency of wood-based stream restoration in small wadeable streams. The project will use monitoring data from the IMW to identify areas where wood density is low and/or where habitat change is limited and target those areas to add more wood. The total area is 9 miles long and we anticipate adding several hundred pieces of wood to each stream using the low-tech process-based restoration method develop in this IMW using post-assisted log structures (PALS) and beaver dam analogs (BDAs).
