The Snake River is a major tributary of the Columbia River in the U.S. states of Wyoming, Idaho, Oregon, and Washington. The river's length is 1,040 miles (1,674 km), its watershed drains 108,000 square miles (280,000 km²), and the average discharge at its mouth is 56,900 cubic feet per second (1,610 m³/s). The river flows from its source in Yellowstone National Park through a series of mountain ranges, canyons, and plains.

Hundreds of scientists say the only way to restore salmon to the Columbia and Snake rivers is to remove four costly dams. But federal agencies aren't listening. The National Wildlife Federation is mobilizing Americans to speak out against the most recent federal salmon plan. Find out how you can speak up.

An interview with U.S. District Judge Jim Redden, who’s given uncooperative federal agencies clear warning: Submit a viable salmon restoration plan for the Snake/Columbia River Basin, or face the possible breaching of four major dams.
