Fish Passage

State highways cross hundreds of streams and rivers in Washington. At many of those locations, culverts are too small or otherwise inadequate to allow fish to migrate upstream and downstream as necessary for growth and reproduction. WSDOT has been working for more than two decades to correct these inadequate culverts to improve fish habitat.
