About Stanley Dam

The primary purpose of Stanley Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Ragland, James And Anna (private). It impounds the Trib. South Anna River.

The dam stands 36 feet tall and stretches 400 feet across, has a maximum storage capacity of 645 acre-feet, and collects water from a drainage area of 5 square miles.

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. Notably, no emergency action plan is currently on file for this high-hazard dam.

At 36 feet, this dam is taller than 83% of dams nationwide.
