Insider Tips

Once a year, Lower Granite Dam dewaters their fish ladder for maintenance, and this year, I got to go inside the fish ladder! What an experience! It's pretty cool seeing how the ladder works from the inside and how they count each and every fish that passes through the dam. #fishladder #lowergranitedam #fishpassage #salmon #pnw #snakeriver #columbiariver

Fish Passage on the LSRDs since day one. And year after year, more research is done to improve passage and life for the fish swimming both upstream and downstream. I highly recommend a visit to one of these dams to see for yourself all that goes into fish passage. The fish are probably doing much better than you've been told. #fish #salmon #nature #lowergranitedam #snakeriver #fishpassage #cleanen...

Ronald E Sarbacher

"Great place to visit to get a chance to see fish close up, the staff working there are super nice and happy to answer questions about the dam, fish ladder and the fish. However be aware that fish will not be there all year, we visited on 4th of July and there were a lot of fish, but when I visited in early May there was nothing. We will definitely go again."

Pernille Langenbach

"The staff are extremely friendly. It is fun watching the fish swimming through the passage - some of them were huge! If you time it just right you can see boats going through the dam lock. There is plenty of parking and has several turn out areas on the way to the dam. There are also tons of wild blackberry bushes around the area with huge berries on them."
