  • 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 to 1.1 miles of upstream habitat in a creek flowing from the Berkeley hills to San Pablo Bay, and engaged the surrounding disadvantaged community through K-12 educational programming, a children’s book, and community meetings. This is a multi-phase project, with the Forum supporting Phases 1,2 and 3. Location: Wildcat Creek at the Lower Wildcat Creek Flood Control Channel, in…

  • 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 linear feet of upstream spawning and rearing habitat in a tributary to Corte Madera Creek.

  • 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…

  • 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 Humboldt County, to restore hydrologic connectivity to off-channel habitats and increase low-velocity winter rearing refugia for ESA-listed coho salmon.
