  • 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…

  • Mid-Klamath Tributary Fish Passage Improvement Project

    This ongoing annual project deploys field crews equipped with hand tools to assess and manually treat seasonal low-flow barriers on 30 to 40 tributaries of the Klamath and Salmon Rivers in Siskiyou and Humboldt counties, opening access to approximately 40 miles of cold-water refugia and spawning habitat each summer and fall for Chinook salmon, coho…

  • Little Case Creek Fish Passage Project

Forum funding covered the permitting, cultural and biological surveys, and…

By tracking when, where, and how adult White Sturgeon move through the restoration area relative to the EBCS — a…
