  • Weaver Basin Fish Passage Assessments

    This project assessed 37 unassessed or unknown-status fish passage barriers in the Weaver Creek watershed, a headwater tributary to the Trinity River near Weaverville in Trinity County, to provide baseline data for future fish passage remediation projects benefiting Coho salmon, steelhead, Chinook salmon, and Pacific lamprey, while engaging local students and tribal partners in the…

  • Jenny Creek Man-made Barrier Removal

    This project removed an abandoned man-made concrete barrier on Jenny Creek, the largest tributary in the Klamath River’s hydroelectric reach in Siskiyou County, timed to coincide with the removal of Iron Gate Dam in 2024, to restore access for Coho salmon, Chinook salmon, steelhead, and Pacific lamprey to 1.9 miles of previously blocked habitat. Project…

  • Designing for Sturgeon Passage in the San Joaquin River at the Eastside Bypass Control Structure (Phase 2)

    This project deployed an acoustic telemetry array to track White Sturgeon movement and habitat use in the San Joaquin River Restoration Area downstream of the Eastside Bypass Control Structure in Merced County, in order to inform fish passage design improvements to that structure for the benefit of White Sturgeon, Green Sturgeon, and spring-run Chinook salmon.…

  • North Fork Ryan Fish Passage Design Project

    This project produced engineering designs to replace a blown-out culvert and rock weir barrier on North Fork Ryan Creek — a tributary to Outlet Creek and the Eel River — near Willits in Mendocino County, to restore fish passage for Coho salmon and steelhead trout at all life stages. Location: North Fork Ryan Creek, a…

  • Native Fish Passage in the San Joaquin River at the Eastside Bypass Control Structure

    This project provided technical assistance, environmental permitting, and compliance support for the physical modification of the Eastside Bypass Control Structure (EBCS) on the San Joaquin River in Merced County — a gated flood control structure identified as a significant low-flow passage barrier within the San Joaquin River Restoration Program’s Restoration Area. By funding the renewal…

  • 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…

  • Little Case Creek Fish Passage Project

    This project replaced two culverted road crossings on Little Case Creek — a tributary of Tenmile Creek in Laytonville, Mendocino County — with bridges to open up to one mile of upstream spawning and rearing habitat for endangered Central California Coast coho salmon and steelhead. Forum funding covered the permitting, cultural and biological surveys, and…

  • Designing for Sturgeon Passage in San Joaquin Eastside Bypass (Phase 1)

    This project used acoustic telemetry monitoring of White Sturgeon in the San Joaquin River Restoration Area to directly inform the design of fish passage improvements at the Eastside Bypass Control Structure (EBCS) in Merced County. By tracking when, where, and how adult White Sturgeon move through the restoration area relative to the EBCS — a…

  • Wildcat Creek Fish Passage & Community Engagement Project (Phase 2)

    This project advanced design and community engagement for the replacement of a failing fish ladder on lower Wildcat Creek in unincorporated North Richmond, Contra Costa County — the most downstream of three significant barriers to Central California Coast steelhead migration on the creek. Phase 2 was the second of three Forum-supported phases in a multi-year…

  • Lower Stotenburg Creek Fish Passage Project

    This project removed all fish passage barriers along the downstream-most 0.6 miles of Stotenburg Creek, a small tributary of the Smith River on the coastal plain of Del Norte County, by upgrading or removing four stream crossings and adding habitat complexity features. The work benefited threatened Southern Oregon/Northern California Coast coho salmon, Central Valley steelhead,…
