About Degray Reregulation Dam
The primary purpose of Degray Reregulation 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 Usace - Vicksburg District (federal). It impounds the Caddo near Caddo Valley.
The dam stands 52 feet tall and stretches 1,410 feet across, creates a reservoir covering 90 acres, has a maximum storage capacity of 6,800 acre-feet, and collects water from a drainage area of 480 square miles. Completed in 1971, the structure is well into its service life at over 50 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 07/22/2020.
At 52 feet, this dam is taller than 93% of dams nationwide.
