The International Columbia River

The Council and the Columbia Basin Trust (CBT) aim to improve public access to environmental data and general information about the international aspects of the Columbia River. Below are links to environmental data from both sides of the international border, Columbia River history in British Columbia and the United States, hydropower generation at Columbia River dams in both countries, and the history and future of the Columbia River Treaty.

The Council, an agency of the states of Idaho, Montana, Oregon, and Washington, is responsible for long-range electric energy planning in the Northwest and also for protecting and enhancing fish and wildlife that have been affected by the construction and operation of hydropower dams in the United States portion Columbia River Basin.

The CBT, an agency of the Province of British Columbia, also addresses the impacts of Columbia River Basin dams – specifically the impacts of the three Columbia River Treaty dams in the province. Created by the people, for the people, the Trust serves the affected area by assisting communities through funding and grants for programs including arts; culture and heritage; business advocacy; environment; scholarships; and community development. In addition, the Trust supports regional initiatives such as climate change adaptation, water stewardship, literacy, youth engagement, and land conservation.

Through this site, the Council and CBT hope to create greater public awareness of the environmental characteristics of the basin, its history, and its future.
