The Upper Deschutes River Basin in central Oregon includes the Deschutes River, Crooked River, and Whychus Creek systems. Surface water in the Upper Deschutes River basin has been almost fully allocated since the early 1900s, primarily for agricultural uses. Prior studies assessed projected water supplies and demands through 2050 and indicated an overall 230,000 acre-foot unmet annual average demand, including agricultural, instream flow, and groundwater (municipal) needs.

Building off of these efforts, Reclamation and the Deschutes Basin Study Work Group (BSWG), through an agreement between Reclamation and the Deschutes Basin Board of Control (DBBC), will complete the Upper Deschutes River Basin Study (Basin Study). Reclamation and DBBC are each responsible for 50 percent of the study costs; a grant from the Oregon Water Resources Department (OWRD) is funding the non-Federal share. The objectives of the Basin Study are to:

  • Develop a comprehensive analysis of water supply and demand, integrating and updating the analyses to account for climate change
  • Analyze how existing operations and infrastructure will perform under the projected future water supply conditions and demands
  • Develop and evaluate options for addressing identified water imbalances
  • Complete analysis to compare relative cost, environmental impact, risk, stakeholder response, and other common attributes of identified options

While the study will not propose any specific project, program, or plan, it will provide a current and broadly-shared basis for future water management in the basin. A communication and outreach plan will be developed and implemented to engage and inform the public and others. Please send questions, comments, and suggestions to bor-pnr-udbasinstudy@usbr.gov.
