Pacific Power and Light Company operates the Wallowa Falls Hydroelectric Project, located in Wallowa County, Oregon. The project, with a generating capacity of 1.1 megawatts, is situated on the East Fork Wallowa River, West Fork Wallowa River, and Royal Purple Creek, approximately seven miles south of Joseph. It features a small concrete diversion dam, a rock-filled timber crib dam, a steel penstock, a powerhouse with a single generating unit, and a transmission line connecting to the local electric grid. The project provides recreational opportunities such as camping, hiking, horseback riding, picnicking, and fishing.

The Wallowa Falls Hydroelectric Project, originally constructed in 1921, replaced several small generation sources in the Wallowa Valley and has been in service since then. The current license, issued in 2017 for a period of 40 years, includes measures to protect bull trout and their habitat, as well as enhance the recreational experience for visitors. The project is surrounded by various recreational facilities managed by Pacific Power, the U.S. Forest Service, and the Oregon State Parks and Recreation Department, offering opportunities for outdoor activities and exploration.
