Fish passage maps & data

Find fish passage projects on a map

Tips for using our interactive map:

• Use the layers to view which sites have been corrected and which sites remain total or partial barriers.
• Click on the map to learn which species of fish are present at a particular site and view more photos.
• Turn different layers on and off to know where different boundaries are located
• Use the measure tool to understand how close or far apart sites are.
• Click the “In Design” layers on to view projects completed or programmed for completion over the next few years.
• Open in a separate browser tab for the full interactive map experience.

Our progress correcting barriers

As of June 2021, we completed 365 fish passage barrier corrections statewide. This improved access to approximately 1,215 miles of upstream habitat for fish. Of the 365 statewide corrections, WSDOT corrected fourteen fish passage barriers last year, thirteen of which were in the injunction area, opening 54 miles of stream habitat.
