Margaret Phillips Lake Dam

About Margaret Phillips Lake Dam

The primary purpose of Margaret Phillips Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Fayette County Board Of Commissioners Thomas Concrete Of Georgia Inc (private). It impounds the Unknown near Fayetteville.

The dam stands 16 feet tall and stretches 560 feet across, creates a reservoir covering 16 acres, has a maximum storage capacity of 239 acre-feet, and collects water from a drainage area of 860 square miles. Completed in 1960, 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 poor, meaning the dam has recognized safety deficiencies that require remediation to address risks. An emergency action plan is in place for this dam. The most recent inspection on record was 01/19/2017. That was 9 years ago, which is on the longer end for a high-hazard structure.
