Mirror Lake Dam

About Mirror Lake Dam

The primary purpose of Mirror Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by City Of Villa Rica Mirror Lake Community Association (local government). It impounds the Town Branch near Villa Rica Environs.

The dam stands 34 feet tall and stretches 300 feet across, creates a reservoir covering 95 acres, and has a maximum storage capacity of 2,156 acre-feet. Completed in 1947, the structure is well-established, with more than 75 years of service.

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 fair — the dam has minor deficiencies that are being addressed or do not pose an immediate safety threat. An emergency action plan is in place for this dam. The most recent inspection on record was 02/26/2019. That was 7 years ago, which is on the longer end for a high-hazard structure.

At 34 feet, this dam is taller than 80% of dams nationwide.
