Agreement-in-principle reached to modernize Columbia River Treaty

An agreement-in-principle to modernize the Columbia River Treaty is being heralded as a major milestone following years of negotiations between Canada and the U.S.

«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,» said U.S. President Joe Biden in announcing the development.

In a separate statement, Prime Minister Justin Trudeau said extensive engagement with Indigenous and local communities ensured that all interests are being heard.

«For more than 50 years, the Columbia River Treaty has played a crucial role in reducing flood damage and providing clean energy to millions of households, businesses and industries in both of our countries,» Trudeau said.

The Columbia River flows almost 2,000 kilometres from the Canadian Rockies, through southeast British Columbia and across the border into Washington state before emptying into the Pacific Ocean on the Washington-Oregon border.

The watershed generates vital hydro electricity courtesy of 60 dams on the main stem and tributaries, supplying almost half of B.C.'s total hydroelectric power and more than 40 per cent of the U.S. total.

River water flow and the sharing of the electricity and money generated from it is governed by a treaty originally hammered out in 1964.

In 2022, B.C. received roughly $420 million in Canadian entitlements from power generation at U.S. dams based on water flows from Canada.

According to the prime minister's statement, the updated treaty will cover concerns not addressed in the original document — including ecosystems and Indigenous values — while reducing flood risk and promoting clean energy goals.
