  • Mid-Klamath Tributary Fish Passage Improvement Project

    This ongoing annual project deploys field crews equipped with hand tools to assess and manually treat seasonal low-flow barriers on 30 to 40 tributaries of the Klamath and Salmon Rivers in Siskiyou and Humboldt counties, opening access to approximately 40 miles of cold-water refugia and spawning habitat each summer and fall for Chinook salmon, coho salmon, and steelhead.

  • Mid Klamath Creek Mouth Enhancement Project

    This project annually assessed and manually improved fish passage at the mouths of up to 41 cold water tributaries along a roughly 75-mile stretch of the mid-Klamath River between Weitchpec in Humboldt County and Cottonwood Creek in Siskiyou County, enhancing thermal refugia access for coho salmon, Chinook salmon, and steelhead during critical low-flow summer and fall migration periods. Location: Mainstem Klamath River tributaries from Weitchpec, Humboldt County (river mile ~143) upstream to Cottonwood Creek, Siskiyou County — a reach spanning portions of Humboldt and Siskiyou Counties on and adjacent to the Klamath National Forest. Work focused on the first 1,000…

  • Seiad Creek Off-Channel Connection / Fish Passage Enhancement Project

    This project restored connectivity between Seiad Creek and three previously constructed off-channel ponds — Alexander, Stender, and Durazo — in Siskiyou County, California, a tributary system of the Klamath River. By removing sediment blockages and installing wood and rock structures to redirect flow, the project improved access to 19,000 square feet of critical off-channel rearing habitat for ESA-threatened Klamath River Coho salmon, Chinook salmon, and steelhead, where off-channel winter habitat is a documented limiting factor in salmonid recovery.

  • Mid Klamath Fish Passage Improvement Project

    This ongoing annual project deploys trained crews each summer to assess and manually treat fish passage barriers at the mouths of up to 72 priority tributaries to the Klamath, Salmon, and Lower Scott Rivers across Humboldt and Siskiyou Counties. Barriers including debris jams, boulder cascades, and perched alluvial deltas are modified using hand tools to create step-pool fishways, and brush bundles installed to enhance thermal refugia. The project benefits coho salmon, Chinook salmon, and steelhead, with over 80% of treated sites showing documented increases in salmonid presence post-treatment by 2022.
