Wells Dam

Wells Dam is located in Douglas County, WA, approximately 8 miles from the town of Pateros in the Mid-Columbia River. It is operated by the Douglas County PUD and was completed in 1969. The design of the project is unique because the generating units, spillways, switchyard, and fish passage facilities are combined in one structure called the hydrocombine. Most of the energy generated by Wells Dam is sold to other utilities including Puget Sound Energy, Portland General Electric, PacificCorp, and Avista.

FERC issued a new license for the project on November 9, 2012. The license is valid for 40 years.
