Columbia River Basin Hydro-Graphics
THE COLUMBIA RIVER BASIN spans 1 Canadian province, 7 US states and 11 tribal nations. Over 11 million people rely on this river, now threatened by climate change, infrastructure, pollution and resource extraction. Receding glaciers and diminishing snow pack is reducing water supply. Infrastructure that includes over 400 dams impacts habitats, impedes fish migration and restricts traditional river usage. Industrial, nuclear, mining and agricultural waste threaten water quality and habitat. Extraction of timber, water and fish weakens ecosystems and strains relations between Canada, U.S. and Tribal Nations. Today public and private transboundary efforts are fostering sustainable solutions, dams are being re-evaluated and the renegotiated 2014 Columbia Basin Treaty may become a model of responsible joint management.
