Fish Passage

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