This project improves fish passage and habitat conditions at RM3.2 in McDonald Creek, providing much better access to 4.5 miles of Coho habitat and 6.1 miles of ESA-listed Steelhead and Cutthroat habitat by updating the Agnew Irrigation District water diversion facility. Concurrent with barrier removal, the adjacent degraded stream channel will be restored. The project will be accomplished by 1) improving the Agnew diversion head gate, canal, bypass, and fish screen; removing portions of the structure from the stream channel; building an all-season fish passage structure; and 2) restoring the degraded channel and floodplain near the diversion dam.
