Columbia River Treaty

“…we have never given up our rights to our mother, our mother’s resources, our governments and our religion; we will survive and continue to govern our mother and her resources for the good of all for all time.” ~ Okanagan Nation Declaration

The Columbia River Treaty (CRT) is a transboundary water storage treaty, between Canada and the US, that has two major components: holding back 15.5 million acres/feet of water for flood control, while also optimizing hydroelectric energy production in the Columbia watershed every year. This storage of water has generated millions of dollars of revenue, the majority of which largely goes to the Province of British Columbia as annual general revenue.

The CRT resulted in BC storing a large amount of the annual spring run-off behind three Canadian dams (Duncan Dam, Hugh Keenleyside Dam, and Mica Dam), that flooded the Slocan Valley (Arrow Lakes) and converted the Upper Columbia watershed into a massive reservoir system, flooding an est. 270,000 acres, forever altering the environment.

The CRT was developed and agreed upon by Canada and the US without consultation, involvement or consent of the Syilx Okanagan Nation. This exclusion of Syilx Okanagan peoples in the original Columbia River Treaty process, alongside its dams and their impacts, represent one of the most significant and on-going infringements of Syilx Okanagan Title and Rights.


In 1964, the Governments of Canada and the United States entered into the CRT, which altered river flows and ultimately commodified the international river system of the Columbia Basin. This is one of the largest infringements on the Syilx Okanagan territory and has profound and lasting impacts on Syilx Okanagan people, Title and Rights, territory and way of life.

Its dams industrialized the Columbia river system, destroyed thousands of square kilometers of land, permanently disrupted natural ecosystems, and threatened a multitude of species that call this territory home. The flooding desecrated historical Syilx Okanagan villages, sacred sites, burial grounds, and food harvesting areas, breaking many of the cultural and familial connections Syilx Okanagan communities held with the Upper Columbia and nx̌ wntkwitkw (Columbia River).


Canada and the United States started preparing for the renegotiation of the CRT in the spring of 2018, as the flood control component of the Treaty otherwise terminates in 2024. Regardless of termination of the flood control component, hydro-electric production will continue. Over the decades, the leadership provided by the Syilx Okanagan Nation’s Chiefs Executive Council (CEC), guided by Syilx Okanagan knowledge keepers, advisors, and language speakers, ensured the Syilx Okanagan Nation was not excluded from the CRT negotiations this time around.

In 2018, Global Affairs Canada made an initial unilateral decision to exclude the First Nations from direct participation in the US-Canada CRT Renegotiation process between Canada and the US. Through the hard work and dedication of Syilx Okanagan leadership and staff, the deputy PM and Minister of Global Affairs Canada, Minister Freeland reconsidered this previous decision and in April 2019, gave us a seat at the US-Canada CRT negotiation table. This was a hard-fought achievement which included legal intervention, advocacy and negotiation support.

The current CRT negotiation represents the first time any First Nation has ever been at the table during international treaty negotiations. Our presence at these negotiations is ground-breaking and has set a precedent for Indigenous communities around the world to ensure that Indigenous rights and participation in treaty negotiations are recognized.
