About Robins Lake Dam
The primary purpose of Robins Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Adams County Board Of Supervisors (local government). It impounds the Robins Bayou near Natchez.
The dam stands 32 feet tall and stretches 400 feet across, creates a reservoir covering 36 acres, has a maximum storage capacity of 886 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1973, 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 unsatisfactory, indicating serious safety deficiencies exist that require immediate attention or remedial action. Notably, no emergency action plan is currently on file for this high-hazard dam. The most recent inspection on record was 02/28/2023.
At 32 feet, this dam is taller than 76% of dams nationwide.
