Victoria

About Victoria

The primary purpose of Victoria is hydroelectric. The dam generates hydroelectric power by channeling water through turbines, converting the energy of flowing water into electricity. It impounds the West Branch Ontonagon near Ontonagon.

The dam stands 210 feet tall and stretches 860 feet across, creates a reservoir covering 250 acres, has a maximum storage capacity of 10,300 acre-feet, and collects water from a drainage area of 661 square miles. Completed in 1930, the structure is well-established, with more than 75 years of service.

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. The most recent inspection on record was 06/08/2022.

At 210 feet, this dam is taller than 99% of all dams in the United States.
