Lower Nesbit Ferry Lake Dam

About Lower Nesbit Ferry Lake Dam

The primary purpose of Lower Nesbit Ferry Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Nesbit Lake Homeowners Association Inc. (private). It impounds the Unknown near Roswell.

The dam stands 42 feet tall and stretches 315 feet across, creates a reservoir covering 12 acres, and has a maximum storage capacity of 256 acre-feet. Completed in 1993, the structure is 33 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 02/17/2016. That was 10 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.

At 42 feet, this dam is taller than 89% of dams nationwide.
