Document Description
The project will rehabilitate an existing set of concrete weirs constructed in the 1950's to provide spring run salmon and steelhead passage on Big Chico Creek. The fish ladder is situated in ~350 ft of stream channel and is comprised of 18 existing weirs. The project will include partial demolition and encasement of existing weirs and the installation of 6 new weirs. All new concrete will be integrally colored and textured to match adjacent basalt boulders. Upstream pools and downstream bed will receive permeation grouting to stabilize the bed and maintain water. Passage slots will be stainless steel, with aluminum flashboards to manage pool depths. Project also includes an extensive outreach component that addresses, among other findings, existing fishery, historic declines, and habitat needs.
