Forum-Funded Restoration Projects

Since 2012, The Forum has helped support projects across California, from research, assessment, implementation and monitoring of fish passage improvement and habitat enhancement, collectively representing a significant investment in the recovery of anadromous fish populations statewide.

From 2012-2025, the California Fish Passage Forum has supported 53 projects across California, collectively representing a significant investment in the recovery of anadromous fish populations statewide. These projects include 36 projects removing one or more fish passage barriers, six habitat enhancement projects, four research and two monitoring projects, and two fish passage assessment projects. These have lead to 70+ barrier removals, opening 300 miles of habitat, and engaging 2,249 partner organizations.

Dutch Bill Creek Market Street Weir Repair Fish Passage Improvement Project

This project will design and permit repairs to a failed weir at the site of the original 2009 Dutch Bill Creek Barrier Elimination Project near Camp Meeker, restoring fish passage for endangered coho salmon and threatened steelhead trout to upstream spawning…
Adobe Creek Barrier Assessment, Design and Permitting

This project will fund preliminary engineering design, surveying, and permitting to replace a failed 1929 box-culvert bridge, fish ladder, and degraded rock weirs at the Old Adobe Road crossing of Adobe Creek with a new clear-span bridge, restoring passage for federally…
Wildcat Creek Fish Passage & Community Engagement Project (Phase 3)

This project is retrofitting a chronically clogged fish ladder and sediment basin on lower Wildcat Creek in unincorporated North Richmond and the cities of Richmond and San Pablo, Contra Costa County, to restore passage for threatened Central California Coast steelhead. The…
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,…
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,…
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…
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…
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…
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…
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…
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…
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…
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…
Hosie Low Water Road Crossing Fish Passage Project

This project replaced a low-water road crossing on Mormon Slough with fish-passable box culverts to improve migration conditions for federally threatened California Central Valley steelhead and fall-run Chinook salmon. Located approximately 13 miles upstream of the Calaveras River’s confluence with the…
Wildcat Creek Fish Passage and Community Engagement Project (Phase 1)

This project conducted an ecological engineering assessment of an existing, chronically clogged fish ladder on Wildcat Creek in the unincorporated North Richmond community of Contra Costa County, developed final design plans for a replacement fish passage facility to improve steelhead access…
Ross Valley Sanitary District Shady Lane Abandoned Sewer and Barrier Removal Project

This project removed a concrete-encased abandoned sewer line from the bed of Ross Creek in San Anselmo, Marin County, that had been acting as a 3.5-foot weir and barrier to juvenile steelhead and smolts, restoring natural channel grade and opening 8,000…
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…
Lawrence Creek Off-Channel Habitat Connection Project

This project constructed five large wood and earthwork structures — including a Venturi jam, deflector jam, apex bar jam, inlet jam, and excavated alcove — on Lawrence Creek, a tributary to Yager Creek in the lower Van Duzen River watershed in…
West Tule Creek Diversion Fish Passage Project

This project developed engineering designs for a fish-passable irrigation diversion and fish screen on West Tule Creek, a tributary to Hayfork Creek in Trinity County, to restore 1.5 miles of upstream spawning and rearing habitat for Chinook salmon, coho salmon, steelhead,…
Strawberry Creek at Clam Beach Fish Passage Project
