State highways cross streams and rivers in thousands of places in Washington State, which can impede fish migration. WSDOT has 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. Learn more in the latest Fish Passage Annual Report (PDF 5.1MB) and our new YouTube video on fish passage restoration.
