​Climate Change and the Federal Columbia River 
Power System

​The Bonneville Power Administration, along with its partners at the U.S. Army Corps of Engineers and Bureau of Reclamation that comprise the River Management Joint Operating Committee, are continuously evaluating and anticipating vulnerabilities, risk, and resiliency of the Federal Columbia River Power System. As part of this shared responsibility, the RMJOC commissioned a climate change research project in 2013 with the University of Washington and Oregon State University. This study, which was principally funded by BPA’s Technology and Innovation Office, advances the state-of-the-science in hydroclimate prediction, and takes into account ongoing and expected climate change across the region.  In September 2017, the streamflow dataset from this project was published, and is available for download at:

This part focuses on projected temperature, precipitation, snowpack and streamflow changes in the Columbia River Basin, and most basins in western Oregon and Washington, through the rest of the 21st Century.  Subsequent reports from the RMJOC, papers published by the research teams, and studies conducted for regional processes like Columbia River System Operations and the Columbia River Treaty, will be forthcoming.
