Columbia River Treaty

The Columbia River Treaty was implemented by the United States and Canada in 1964 to govern Columbia River flows for flood control and power generation. After 50 years, both nations are examining its future. The Treaty states that either nation can terminate most of its provisions beginning September 16, 2024, with a minimum 10 years’ written notice.

In December 2013, the U.S. Entity (Bonneville Power Administration and U.S. Army Corps of Engineers’ Northwestern Division) provided a Regional Recommendation to the U.S. State Department that the Treaty be modernized to reflect the current value of power and flood control operations, and support healthy ecosystems. The document also included important statements regarding the current and future importance of navigation on the river system.

PNWA members and staff have routinely met with the Northwest Congressional delegation, U.S. Army Corps of Engineers, and U.S. State Department to ensure that impacts to the safety and efficiency of commercial navigation on the Columbia Snake River System are considered as the treaty review and negotiation process moves forward.
