About Crystal Dam
The primary purpose of Crystal 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 Bureau Of Reclamation (federal). It impounds the Gunnison River near Delta.
The dam stands 323 feet tall and stretches 620 feet across, creates a reservoir covering 301 acres, has a maximum storage capacity of 30,726 acre-feet, and collects water from a drainage area of 3,965 square miles. Completed in 1977, the structure is 49 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. An emergency action plan is in place for this dam. The most recent inspection on record was 07/20/2023.
At 323 feet, this dam is taller than 99% of all dams in the United States.
