About Turner Hill Lake Dam
The primary purpose of Turner Hill 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 Allen Family Stonecrest Llc (private).
The dam stands 31 feet tall and stretches 450 feet across, has a maximum storage capacity of 1,331 acre-feet, and collects water from a drainage area of 3,520 square miles. Completed in 1990, the structure is 36 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 03/16/2017. That was 9 years ago, which is on the longer end for a high-hazard structure.
