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 the creek. Phase 2 supported an ecological engineering assessment of existing design drawings and extensive community outreach, including K-12 education programming and tribal consultation, with the ultimate goal of restoring access to 1.125 miles of spawning and rearing habitat and reconnecting the watershed to San Pablo Bay.
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 features. The work benefited threatened Southern Oregon/Northern California Coast coho salmon, Central Valley steelhead, coastal cutthroat trout, Chinook salmon, and Pacific lamprey by opening critical non-natal winter rearing habitat and reconnecting the creek to the mainstem Smith River.
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 San Joaquin River in San Joaquin County, the project removed one of the worst-ranked passage barriers in the lower Calaveras watershed, reducing flow velocities at the crossing and significantly expanding the window of passable conditions for both adult and juvenile salmonids.
