The Pacific Northwest was once home to one of the greatest salmon runs in the world: The Columbia / Snake river system. But all remaining Snake River salmon are facing extinction because four aging dams in Washington stand in their way to reaching their pristine, natal cold water streams in central Idaho and beyond.

Now, the operation of those four dams—Ice Harbor, Little Goose, Lower Monumental, Lower Granite—is under reconsideration. Scientists say taking out the dams is the single best thing we can do to save the salmon.

Free the Snake, save the salmon, remove the dams.
