A new, consolidated Trinity River weir site—supported through Reclamation collaboration and funding—enhances salmon monitoring and strengthens Tribal and state partnerships.
Reclamation has worked closely with the California Department of Fish and Wildlife (CDFW) and the Hoopa Valley Tribe to support their decision to bring two long‑running weir sites together into a single monitoring location on the Trinity River in California. The updated approach strengthens ongoing salmon run‑size estimation efforts, improves monitoring conditions for Chinook, coho, and steelhead, and supports Tribal harvest traditions. By helping coordinate the transition and providing essential funding, Reclamation continues its long-standing role in advancing collaborative fisheries management across the Klamath Basin.
The consolidation of the project will improve fish health for Chinook salmon, coho and steelhead, improve methods for monitoring, protect Tribal harvest opportunities, and strengthen the long-term partnership of agencies working to improve commercial, recreational and subsistence fisheries within the Klamath Basin.
