About Steeles Mill Reservoir Dam

The primary purpose of Steeles Mill Reservoir Dam is water supply. The dam stores water for municipal, industrial, or agricultural use, helping ensure a reliable supply for the surrounding area. The dam is owned by Henry County Water & Sewage Authority (local government). It impounds the Towaliga River near Locust Grove.

The dam stands 42 feet tall and stretches 175 feet across, creates a reservoir covering 121 acres, has a maximum storage capacity of 8,333 acre-feet, and collects water from a drainage area of 56 square miles. Completed in 1980, the structure is 46 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 01/27/2016. 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.
