Today, throughout the Snake River Basin, imperiled populations of salmon continue to die at rates far below sustainable replacement levels. Scientists have told us for decades that breaching the four federal dams in the lower Snake River. Congressman Mike Simpson of Idaho has an ambitious proposal to remove the dams and invest billions in energy, irrigation and transportation infrastructure. But elected leaders in Washington and Oregon must step up too before we lose the fish that define the region’s ecology and cultural heritage. Good work is happening in places like the Lostine, but ultimately, the success of those collaborations depend on restoring a free-flowing Snake River.
