Couse Creek PA 78 Design

The Asotin County Conservation District sponsored the Couse Creek Project Area (PA) 78 Design project to develop a full final design report, ready to construct engineering plans, and complete environmental compliance including permit and other requirements. PA 78 is identified as a Tier 1 project in the Asotin County Conceptual Restoration Plan. There is an existing stream buffer in place through the Conservation Reserve Enhancement Program (CREP). The design report and engineering plans for PA 78 includes improving access to flood channels, controlling invasive vegetation encroachment and organizing boulder clusters and add large woody debris to increase complexity to benefit Snake River steelhead. This project has funding secured to implement the designs that were completed by this project.

The project will increase access to flood channels which will improve floodplain connection, promote riparian function, and provide instream habitat complexity through the placement of large wood structures and boulder clusters, to enhance juvenile Snake River steelhead habitat for all life stages.
