Northwest RiverPartners advocates for the bettering of our communities, our region, and the world through the low-cost, carbon-free hydropower system. Together, we encourage the balanced use of Columbia Basin rivers, while working towards solutions that help hydropower and salmon coexist and thrive.



In May of 2019, Washington’s Governor Inslee approved a $750,000 study into the impact of breaching the four lower Snake River dams. Until now, the study has consisted of interviews with representative stakeholder groups. With this new survey, communities in Washington have been given an opportunity to speak for themselves. The time to defend our access to affordable, clean, and reliable hydroelectricity is now!


Northwest Hydropower by the Numbers

Frequently Asked Questions about Hydro

Are fewer salmon returning to dammed rivers compared to free-flowing rivers?
Answer: Nearly all rivers along the entire North Pacific Coast—from southeast Alaska to southern Oregon—are experiencing similar or worse trends in returns when compared to the lower Columbia and lower Snake rivers.

Do hydroelectric dams lead to significant mortality for salmon?
Answer: Data shows that fish survival past modernized dams can be as good or better than naturally flowing rivers.

Did the lower Snake River dams cause Snake River Chinook and sockeye to become threatened?
Answer: During the same timeframe, ocean conditions dramatically shifted from cooler-than-normal temperatures to warmer-than-normal temperatures. This type of shift is a leading indicator of reduced adult salmon returns.

Is hydropower an important part of our clean energy future?
Answer: Hydropower is critical to the region’s ability to meet these goals because it is carbon-free and because of its energy storage capabilities.

Can batteries become a substitute for hydropower in the Northwest?
Answer: We will likely need all our existing hydropower, plus new sources of energy paired with batteries, to keep up with regional electricity needs.

Are Southern Resident orcas being harmed by the existence of the lower Snake River dams?
Answer: Southern Resident orcas spend most of their time in the Salish Sea. As a result, a NOAA Fisheries’ analysis showed that Chinook from the Salish Sea—not the Columbia or Snake rivers—are the top priority salmon stock for Southern Resident orcas.

“Miller said the dams not only keep energy affordable, but they are an important supply of electricity where there are more and more demands. Pointing to a symposium in Portland last October, attended by 400 utility leaders and policymakers, Miller said securing the region’s energy sources is imperative.”

We’re constantly updating our data and resources with the most recently available science. Our resources page provides links to fact sheets, files, and websites that offer great information on the Northwest hydropower system and salmon.


When it comes to reducing our reliance on carbon-emitting energy sources, the Northwest is leading the nation with the use of hydropower.

Hydropower acts like a giant, clean battery, helping us provide power to millions of homes.

Northwest farmers feed the region and the world with vital crops such as apples,
potatoes, corn, peas, alfalfa, hay, grapes, and wheat. They rely on the river for irrigation and transport of these goods.

The Northwest economy was built on and continues to thrive with abundant, low-cost hydropower.

Northwest dams and reservoirs help protect the region’s families and businesses from devastating floods, saving lives and property.

Hydropower accounts for 47% of the total average annual electricity production and 80% of the carbon-free annual electricity production in the Northwest.

New fish protections have been put into place at all eight lower Columbia and lower Snake River dams, increasing juvenile survival rates to between 93% and 99% at each dam.
