About Pratt Lake Dam
The primary purpose of Pratt Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Caltex Ranch Lp (private). It impounds the Mine Creek near Athens.
The dam stands 65 feet tall and stretches 2,950 feet across, creates a reservoir covering 282 acres, has a maximum storage capacity of 8,219 acre-feet, and collects water from a drainage area of 10 square miles. Completed in 2003, the structure is relatively new.
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. An emergency action plan is in place for this dam. The most recent inspection on record was 12/19/2018. That was 7 years ago, which is on the longer end for a high-hazard structure.
At 65 feet, this dam is taller than 96% of all dams in the United States.
