It's Time to Restore the Lower Snake River

The Issue at a Glance


Snake River Salmon and Steelhead are Counting on Us

The Association of Northwest Steelheaders is dedicated to removing the Lower Granite, Little Goose, Lower Monumental, and Ice Harbor dams on the lower Snake River, which have been decimating endangered fish populations since they were built between 1955-1975.

Restoring a free-flowing lower Snake River is essential to achieving five main goals:

People have been talking about removing the four lower Snake River dams for decades. With over 50 years’ worth of science documenting their negative impacts on endangered fish populations, it is clear that removing these dams would dramatically improve populations and protect them from looming extinction.

The 2020 Draft Environmental Impact Statement that federal agencies prepared to save Columbia and Snake River salmon and steelhead from extinction confirmed that removing the four lower Snake River dams is the only management option they considered that would meaningfully recover these endangered fish populations from risk of extinction. And yet, they didn’t move forward with breaching these dams. Instead, their Record of Decision implemented a management alternative only slightly different from the 2018 Flexible Spill Agreement.

Despite spending more than $17 billion in tax dollars to attempt to recover these critical populations over the past 25 years, 2019 salmon returns dropped to historic lows – a clear sign that this trend will continue if we move forward with status quo management.

Restoring a free-flowing lower Snake River will improve fishing opportunities on the lower Columbia

Check out our webinar from September 2020 to learn more about why lower Columbia anglers need to push for Snake River restoration if we want to recover meaningful fishing seasons and salmon runs.

Dams Threaten Fish


Dams are difficult barriers that endangered fish must pass upstream to reach their spawning grounds. They cause substantial stress to the fish and can result in injury, reducing their overall fitness and ability to successfully complete the 900+ mile journey.


Dams reduce the speed that water flows through the Snake and Columbia River systems, making the time it takes these endangered fish to migrate much longer, which requires them to obtain more nutrition to sustain themselves.


Dams increase the water temperature of the river, sometimes above the 70-degree threshold that salmon and steelhead can survive in.


Predators such as sea lions have become accustomed to preying on juvenile salmon that are released below the dam through fish bypass systems, increasing the threats that salmon face on this journey.

What folks are saying about Snake River salmon and steelhead

Breaching the Lower Snake River dams “is the most certain and robust solution to SR salmon and steelhead recovery. No other action has the potential to improve overall survival two to three-fold and simultaneously address both the orca and salmon recovery dilemma”

Oregon Governor Kate Brown, February 2020

“We need to stop thinking about what currently exists and ask ourselves, ‘What do we want the Northwest to look like in 10, 20, 30, 40, 50 years?”

Idaho Congressman Mike Simpson

“Historically, the Columbia River Basin was the largest salmon producing river system in the world…we are now struggling at about one percent of their historical potential. That is inexcusable for a system that is so iconic, for a species that is so iconic, for a system that is so magnificent.”

Ed Bowles, Fish Division Administrator, Oregon Department of Fish and Wildlife in “The Greatest Migration”

“Communities must have the opportunity to collaboratively develop a transition plan to ensure the region’s needs will continue to be met. We can work together to ensure federal and state investments would replace the dams’ benefits and help impacted communities. We must insist that the people who depend on the lower Snake River have a say in its future. We must insist on a path forward that works for salmon and people.”

Wendy McDermott, Director of the Puget Sound-Columbia Basin for American Rivers
