Hosie Low Water Road Crossing Fish Passage Project (2022)
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.

Central California Traction Railroad Bridge Fish Passage Improvement Project (2016)
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 13.4 miles of stream to fall-run Chinook salmon and Central Valley steelhead — a core recovery population in the Southern Sierra and San Joaquin watershed.
