About Lake Maumelle Dam
The primary purpose of Lake Maumelle Dam is water supply. The dam stores water for municipal, industrial, or agricultural use, helping ensure a reliable supply for the surrounding area. The dam is owned by Central Arkansas Water (local government). It impounds the Maumelle Creek near Little Rock.
The dam stands 67 feet tall and stretches 2,550 feet across, creates a reservoir covering 8,900 acres, has a maximum storage capacity of 220,000 acre-feet, and collects water from a drainage area of 137 square miles. Completed in 1957, 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. Its condition is rated satisfactory, indicating no existing or potential dam safety deficiencies are recognized. Notably, no emergency action plan is currently on file for this high-hazard dam. The most recent inspection on record was 06/22/2022.
At 67 feet, this dam is taller than 96% of all dams in the United States.
