New StoryMap Release: Connecting People and Fish in Urban and Rural Watersheds

This interactive StoryMap, highlights two community-centered restoration efforts, one in the urban East San Francisco Bay and one in the rural Klamath River Basin. In rugged northern California, the Salmon River Restoration Council and Mid Klamath Watershed Council use an all-hands-on-deck approach to improve fish passage at hundreds of tributaries to the Klamath and Salmon…
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.…
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…
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…
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…
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…
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…
Branciforte Creek Dam Removal

This project removed the 8-foot Cahill Dam, built in 1931, from Branciforte Creek — the last tributary of the San Lorenzo River before it reaches the Pacific Ocean in Santa Cruz County. The dam had blocked migration and buried natural spawning substrate under 250 feet of sediment. Following removal, nearly three miles of upstream spawning…
Grape Creek Streamflow Restoration — Water and Wine Program

This project addressed critically low dry-season flows in Grape Creek, a tributary to Dry Creek in the Russian River watershed of Sonoma County, by working with vineyard landowners to install off-stream ponds fed by groundwater and winter rainfall. This eliminated in-stream diversions that had historically reduced flows during salmon and steelhead migration periods. Additional work…
Conner Creek Migration Barrier Removal Project

This project addresses two fish passage barriers on Conner Creek, a tributary to the Trinity River below Lewiston Dam. The Trinity River is a major tributary to the Klamath River. The project sites — Conner Creek Road (Crossing #1) and Red Hill Road (Crossing #2) — are located approximately 8 miles west of Weaverville in…
