The impact of the four lower Snake River dams on wild salmon and steelhead is no longer a question. The dams are driving wild populations to extinction. Currently 42% of the spring/summer Chinook populations in the Snake River basin are at quasi extinction threshold.

The science indicates that each dam reduces fish survival by 20 to 25%.

It’s important to understand that salmon and steelhead are harmed throughout the entire 140-mile slack water system created by the dams, not just the concrete and turbines at each dam.

Despite $20 billion dollars in efforts to mitigate the impacts of the hydropower system and other fish recovery efforts, our region is left with a fraction of what was once the greatest run of salmon and steelhead in the Lower 48. Inaction is a clear path to extinction.
