About Cpud Middle Fork
The primary purpose of Cpud Middle Fork 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 Calaveras Public Utility District (public utility). It impounds the Middle Fork Mokelumne River near West Point.
The dam stands 112 feet tall and stretches 900 feet across, creates a reservoir covering 45 acres, has a maximum storage capacity of 2,525 acre-feet, and collects water from a drainage area of 28 square miles. Completed in 1939, 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 08/30/2023.
At 112 feet, this dam is taller than 98% of all dams in the United States.
