About Walterville Storage Pond
The primary purpose of Walterville Storage Pond 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 Eugene Water And Electric Board (public utility). It impounds the Mckenzie River near Walterville.
The dam stands 10 feet tall and stretches 3,000 feet across, creates a reservoir covering 65 acres, and has a maximum storage capacity of 345 acre-feet. Completed in 1951, the structure is well into its service life at over 50 years old.
This dam carries a high hazard potential classification, which means that a failure or uncontrolled release of water would likely cause loss of human life. This classification reflects the consequences of failure, not the likelihood — it indicates that people live or work in the area downstream. Its condition is rated satisfactory, indicating no existing or potential dam safety deficiencies are recognized. An emergency action plan is in place for this dam.
