Lower Snake River, ID, OR and WA

The salmon and steelhead of the Snake River are magnificent creatures, traveling over 900 miles from the sea to spawn in Idaho’s high mountain streams.

These fish are central to the lives of many Pacific Northwesterners and to the health of the region's environment and economy.

Unfortunately, this icon of the region is threatened with extinction, due primarily to the effects of the four lower Snake River dams.

Removing these outdated dams and restoring a free-flowing lower Snake River would allow for the restoration of healthy, fishable salmon and steelhead runs to the largest potential block of healthy salmon habitat remaining in the lower 48 states.

The benefits of the four lower Snake dams can be replaced, protecting and enhancing local economies and communities.
