About North Fork Diversion Dam
The primary purpose of North Fork Diversion Dam is hydroelectric. The dam generates hydroelectric power by channeling water through turbines, converting the energy of flowing water into electricity. The dam is owned by Pacificorp (public utility). It impounds the North Fork Rogue River near No Downstream Settlement.
The dam stands 50 feet tall and stretches 150 feet across, creates a reservoir covering 3 acres, has a maximum storage capacity of 309 acre-feet, and collects water from a drainage area of 508 square miles. Completed in 1965, the structure is well into its service life at over 50 years old.
This dam has a significant hazard potential classification, meaning that a failure could cause significant economic damage — flooding roads, bridges, or property downstream — but is not expected to result in loss of life. An emergency action plan is in place for this dam.
At 50 feet, this dam is taller than 93% of dams nationwide.
