The Columbia River Treaty, concluded in 1961 and ratified in 1964, split hydropower and flood control regulation of the river between Canada and the United States. Some of its provisions will expire in 2024, and either country must give ten years’ notice of any desired alteration or termination. The Columbia River Treaty Revisited, with contributions from historians, geographers, environmental scientists, and other experts, is intended to facilitate conversation about the impending expiration. It allows the reader, through the close inspection of the Columbia River Basin, to better grasp the uncertainty of water governance. It aids efforts, already underway, to understand changes in the basin since the treaty was passed, to predict future changes, and to determine whether alteration of the treaty is ultimately advisable.

The Columbia River Treaty Revisited will appeal to those interested in water basin management-scholars, stakeholders, and residents of the Columbia River basin alike.

A Project of the Universities Consoritum on Columbia River Governance The Universities Consortium on Columbia River Governance, with representatives from universities in the U.S. and Canada, formed to offer a nonpartisan platform to facilitate an informed, inclusive, international dialogue among key decision-makers and other interested people and organizations; to connect university research to problems faced within the basin; and to expose students to a complex water resources problem. The Consortium organized the symposium on which this volume is based.
