About Stone Mountain Park Lake Dam
The primary purpose of Stone Mountain Park Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Stone Mountain Memorial Association (private). It impounds the Stone Mountain Creek near Lake Norris Community.
The dam stands 60 feet tall and stretches 1,025 feet across, creates a reservoir covering 392 acres, has a maximum storage capacity of 8,470 acre-feet, and collects water from a drainage area of 9,043 square miles. Completed in 1961, 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 03/16/2017. That was 9 years ago, which is on the longer end for a high-hazard structure.
At 60 feet, this dam is taller than 95% of all dams in the United States.
