About Upper Haig Mill Lake Dam
The primary purpose of Upper Haig Mill Lake Dam is flood risk reduction. The dam is designed to control downstream flooding by temporarily storing excess water during storms and releasing it at a controlled rate. The dam is owned by Dalton Utilities (public utility). It impounds the Haig Mill Creek near Dalton Suburbs.
The dam stands 40 feet tall and stretches 793 feet across, creates a reservoir covering 63 acres, has a maximum storage capacity of 2,607 acre-feet, and collects water from a drainage area of 5,286 square miles. Completed in 1962, 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 03/08/2017. That was 9 years ago, which is on the longer end for a high-hazard structure.
At 40 feet, this dam is taller than 87% of dams nationwide.
