  • Designing for Sturgeon Passage in the San Joaquin River at the Eastside Bypass Control Structure (Phase 2)

    This project deployed an acoustic telemetry array to track White Sturgeon movement and habitat use in the San Joaquin River Restoration Area downstream of the Eastside Bypass Control Structure in Merced County, in order to inform fish passage design improvements to that structure for the benefit of White Sturgeon, Green Sturgeon, and spring-run Chinook salmon.

  • Native Fish Passage in the San Joaquin River at the Eastside Bypass Control Structure

    This project provided technical assistance, environmental permitting, and compliance support for the physical modification of the Eastside Bypass Control Structure (EBCS) on the San Joaquin River in Merced County — a gated flood control structure identified as a significant low-flow passage barrier within the San Joaquin River Restoration Program’s Restoration Area. By funding the renewal and completion of required environmental compliance documents, the project is enabling construction of a 380-foot engineered rock ramp and structural modifications to the EBCS that will improve migration conditions for spring-run Chinook salmon, steelhead, White Sturgeon, Green Sturgeon, and Pacific lamprey.

  • 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.
