It has produced electricity since August 22, 1967. Its operating license from the US Federal Energy Regulatory Commission is next up for renewal in 2012. In addition to the two public utility districts, the project provides electricity to Puget Sound Energy, Portland General Electric, PacifiCorp, Avista Corporation, and the Colville Indian Tribe.[3]

Its reservoir is named Lake Pateros. Just below and adjacent is Carpenter Island boat launch and fish hatchery river access.
