About Stump Lake Dam
The primary purpose of Stump Lake 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 Clearwater Rivr near Idylyld Park.
The dam stands 21 feet tall and stretches 300 feet across, creates a reservoir covering 36 acres, has a maximum storage capacity of 152 acre-feet, and collects water from a drainage area of 42 square miles. Completed in 1953, the structure is well into its service life at over 50 years old.
This dam has a low hazard potential classification, meaning that failure would cause minimal damage, limited primarily to the dam owner's property, with no expected loss of life.
