  • Sharber-Peckham Fish Passage Project

    This project replaced a failing undersized corrugated metal pipe culvert on Galaxy Drive, which had blocked Sharber-Peckham Creek — a Trinity River tributary near Salyer in Trinity County — for at least 20 years. The barrier was replaced with a 12-by-14-foot embedded multi-plate ellipse culvert designed to pass 100-year flows while maintaining a natural streambed. Sharber-Peckham Creek is the greatest single producer of coho salmon between the Hoopa reservation and the North Fork Trinity River, and post-project monitoring found 740 juvenile coho rearing upstream within one year.

  • Salt River Ecosystem Restoration Project

    This large-scale cooperative project addressed sediment aggradation, fish passage, flooding, and drainage throughout the Salt River, a tidally influenced tributary to the Eel River Estuary near Ferndale in Humboldt County. Work included river channel restoration, estuary restoration at Riverside Ranch through levee and tidegate removal, upslope sediment reduction, and flood relief. The project benefits coho salmon, Chinook salmon, steelhead, Pacific lamprey, and tidewater goby — all ESA-listed species — and ten years of surveys have confirmed active fish use of the restored channel.

  • Pinole Creek Fish Passage Improvement Project

    This project improved fish passage through the nearly 400-foot Caltrans I-80 double-bay box culvert on Pinole Creek in the City of Pinole, Contra Costa County. Construction added concrete notch baffles, training walls, a terminal rock pool, and a rocked downstream chute, opening nearly 7 miles of documented spawning and rearing habitat. The project benefits a federally threatened steelhead population recognized as one of very few viable runs within the San Francisco Bay Area.

  • Kelly Gulch Fish Passage Project

    This project replaced an undersized culvert on Forest Service Road 40N39 on Kelly Gulch, a tributary to the North Fork Salmon River within the Klamath National Forest in Siskiyou County, with a bottomless arch culvert allowing natural passage of aquatic organisms, water, sediment, and debris. The culvert was one of the only remaining barriers to anadromous fish on the Klamath National Forest Transportation System, benefiting SONCC coho salmon, steelhead trout, and potentially Pacific lamprey.

  • Dinner Creek Fish Passage Barrier Removal Project

    This project removed three undersized culverts on Dinner Creek at Briceland Thorne Road in Humboldt County — including a complete barrier to all life stages — and supplemented emergency replacement work with habitat improvements including river-run gravels, roughened channel work, and instream fish structures. Located in the South Fork Eel River watershed, the project opened 1.8 miles of spawning and rearing habitat and included riparian revegetation, benefiting coho salmon and steelhead.

  • Carpinteria Creek Fish Passage Project

    This project removed the last major migration barrier in the Carpinteria Creek watershed — an undersized bridge and 100 feet of concrete-lined channel with drop structures — replacing it with a clear-span bridge and a restored natural stream channel incorporating rock and large wood structure. Located in coastal Santa Barbara County, the project opened at least 1.27 miles of historic spawning habitat on the mainstem Carpinteria Creek for the first time in decades, benefiting federally endangered Southern California steelhead. Location: Carpinteria Creek is located in coastal Santa Barbara County, approximately 10 miles southeast of the City of Santa Barbara. It…
