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 Mirror Lake Property Owners Association (private). It impounds the Cullasaja River near Highlands.
The dam stands 22 feet tall and stretches 138 feet across, creates a reservoir covering 27 acres, has a maximum storage capacity of 230 acre-feet, and collects water from a drainage area of 6 square miles. Completed in 1958, 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 fair — the dam has minor deficiencies that are being addressed or do not pose an immediate safety threat. Notably, no emergency action plan is currently on file for this high-hazard dam. The most recent inspection on record was 12/20/2024.
