US would keep more hydropower under agreement with Canada on treaty governing Columbia River

SEATTLE (AP) — The U.S. and Canada said Thursday they have agreed to update a six-decade-old treaty that governs the use of one of North America’s largest rivers, the Columbia, with provisions that officials said would provide for effective flood control, irrigation, and hydropower generation and sharing between the countries.

The “agreement in principle,” reached after six years of talks, provides a framework for updating the Columbia River Treaty. It calls for the U.S. to keep more of the power generated by its dams while improving cooperation between the Bonneville Power Administration, which markets power from dams in the northwestern U.S., and Canadian utilities, to help avoid blackouts.

The U.S. would pay Canada for reservoir capacity to hold back water during flood seasons, protecting downstream communities, at a rate that would begin at $37.6 million per year and increase with inflation. And the agreement would provide Canada with more flexibility in using the water stored in its reservoirs.

“After 60 years, the Treaty needs updating to reflect our changing climate and the changing needs of the communities that depend on this vital waterway,” U.S. President Joe Biden said in a written statement Thursday.

But environmental groups lamented the deal as a missed opportunity to provide more water for imperiled salmon and steelhead runs that have been decimated by dam operations in the Columbia River basin over the past century. While the original treaty ratified in 1964 was designed to cover flood control and hydropower generation, conservationists and Indigenous tribes have long argued that it should be updated to include river health and salmon restoration as a third principle.

“Our community is frustrated and disappointed today,” said Joseph Bogaard, of the nonprofit Save Our Wild Salmon. “The treaty needs to be a tool to address challenges for these fish. There are benefits and certainty for the power sector and for flood risk management, while salmon basically get status quo treatment.”

The Biden administration earlier this year brokered a $1 billion plan to boost salmon runs in the Northwest.

The Columbia River begins in Canada but flows mostly in the U.S. on its 1243-mile (2000.41 kilometer) journey to the Pacific Ocean. It forms most of the border between Washington state and Oregon. Its tributaries account for 40% of U.S. hydropower, irrigate $8 billion in agriculture products, and move 42 million tons of commercial cargo annually, officials noted Thursday.

The Columbia River Treaty came together after a 1948 flood washed away the Oregon community of Vanport, leaving more than 18,000 people homeless.
