About Gibbons Creek Dam
The primary purpose of Gibbons Creek 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 Gibbons Creek Environmental Redevelopment Group Llc (private). It impounds the Gibbons Creek near Navasota.
The dam stands 50 feet tall and stretches 6,150 feet across, creates a reservoir covering 2,770 acres, has a maximum storage capacity of 81,874 acre-feet, and collects water from a drainage area of 85 square miles. Completed in 1981, the structure is 45 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. 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 07/07/2022.
At 50 feet, this dam is taller than 93% of dams nationwide.
