  • Benbow Dam Removal Project

    This project fully removed the Benbow Dam from the South Fork of the Eel River at Benbow Lake State Recreation Area, approximately two miles south of Garberville in Humboldt County. Originally built in the 1930s for power generation, the dam had become a safety hazard blocking upstream migration. Removal spanned two construction seasons (2016–2017) and…

  • Pacific Lamprey Passage Assessment Database (PAD) Project

    This statewide data and GIS infrastructure project developed standardized barrier assessment tools specifically for Pacific lamprey to complement existing salmonid-focused assessments in California’s Passage Assessment Database. Work included creating historical and current distribution GIS layers, defining lamprey-specific data fields, and developing a standard barrier assessment form. The project directly supports prioritization of barrier removal to…

  • Manly Gulch Coho Access and Habitat Restoration Project

    This project replaced a failing road-stream crossing on Camp Road in Manly Gulch — a tributary to the Little North Fork of the Big River flowing through Mendocino Woodlands State Park in Mendocino County — with a 30-foot span timber bridge and realigned approximately 600 feet of channel. Log steps, pools, boulder weirs, rootwads, and…

  • Juvenile Fish Passage Criteria Assessment Project

    This research project tested the leaping abilities of juvenile steelhead and coho salmon ranging from 40–130mm at the Warm Springs Fish Hatchery on Dry Creek in Sonoma County, using a flume with waterfall heights of 6, 12, and 18 inches. Four experiments examined waterfall height, fish size, species differences, and water temperature. Findings directly informed…

  • Central California Traction Railroad Bridge Fish Passage Improvement Project

    This project improved fish passage at the Central California Traction Railroad Crossing on the Stockton Diverting Canal, within the lower Calaveras River system near Stockton in San Joaquin County. A second flume, notches, and a downstream roughened rock ramp were installed to provide passage at flows between 30 and 1,000 cfs. The project opened approximately…
