Natural Flow Study

The Bureau of Reclamation’s Technical Service Center (TSC) is conducting the Revised Klamath River Basin Natural Flow Study (Natural Flow Study) as part of the Klamath Basin Science Initiative. The TSC is taking a comprehensive, unified approach that relies on a partnership with Desert Research Institute (DRI) and United States Geological Survey (USGS) as well as collaboration with National Marine Fisheries Service (NMFS), United States Fish and Wildlife (USFW), and Oregon Water Resources Department as well as local stakeholder engagement. The study evaluates natural streamflow within the Klamath River Basin, which includes 11 watersheds and over 10 million acres in southern Oregon and northern California. The Natural Flow Study is relying on best science practices to provide essential information to develop near-term and long-term solutions for the Klamath River Basin. The final publication of the Natural Flow Study is anticipated January 2025.
