Fish passage

Learn how we're reconnecting streams under state highways to improve fish passage around the state.

State highways cross streams and rivers in thousands of places in Washington State, which can impede fish migration. We have worked for nearly three decades to improve fish passage and reconnect streams to help keep our waterways healthy. WSDOT Fish Barrier Correction is a priority.
