About Hyatt Dam
The primary purpose of Hyatt 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 Keene Creek near Lincoln.
The dam stands 53 feet tall and stretches 775 feet across, creates a reservoir covering 1,120 acres, has a maximum storage capacity of 25,100 acre-feet, and collects water from a drainage area of 11 square miles. Completed in 1923, 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. An emergency action plan is in place for this dam. The most recent inspection on record was 06/14/2023.
At 53 feet, this dam is taller than 94% of dams nationwide.
