Touchet Geomorphic Assessment and Restoration Prioritization Plan
The Touchet River Geomorphic Assessment Project is the product of a progressive community-wide collaboration to improve habitat for ESA listed steelhead and bull trout while simultaneously exploring ways to attenuate flood risk to the community.
The framework of this project was developed so site-specific river/floodplain restoration opportunities are identified within the context of watershed processes. To support the established framework; GeoEngineers’ multi-disciplinary team was retained to conduct a preliminary geomorphic assessment of the watershed upstream of the Highway 12 Bridge, prioritize potential restoration reaches throughout the watershed, and develop conceptual restoration solutions for an approximately 2 mile “Implementation Reach.” Guidance for this work was further developed over the course of several meetings with the Columbia County Levee Round Table Group (LRTG) and the Snake River Salmon Recovery Board’s Regional Technical Team (RTT), which are represented by local, state, and Federal government agencies as well as private landowners and non-profit organizations. This report serves as a foundation for future restoration planning and also provides conceptual restoration details for the top priority reach.
