About Caldron Falls

The primary purpose of Caldron Falls 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 Wisconsin Public Service Corporation (public utility). It impounds the Peshtigo River near Crivitz.

The dam stands 81 feet tall and stretches 1,250 feet across, creates a reservoir covering 1,018 acres, has a maximum storage capacity of 11,500 acre-feet, and collects water from a drainage area of 496 square miles. Completed in 1924, the structure is over a century 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. The most recent inspection on record was 09/07/2022.

At 81 feet, this dam is taller than 97% of all dams in the United States.
