Kenilworth Lake Dam

About Kenilworth Lake Dam

The primary purpose of Kenilworth Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Dekalb County Roads And Drainage Division Kenilworth Estates Community Assoc. Behring Family Trust (local government). It impounds the South River near Stone Mountain.

The dam stands 40 feet tall and stretches 500 feet across, creates a reservoir covering 16 acres, has a maximum storage capacity of 294 acre-feet, and collects water from a drainage area of 169 square miles. Completed in 1953, 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. An emergency action plan is in place for this dam. The most recent inspection on record was 03/19/2019. That was 7 years ago, which is on the longer end for a high-hazard structure.

At 40 feet, this dam is taller than 87% of dams nationwide.
