About Joe Pool Dam
The primary purpose of Joe Pool Dam is flood risk reduction.

It impounds the Mountain Creek near Dallas.
The dam stands 108 feet tall and stretches 22,180 feet across, creates a reservoir covering 7,470 acres, has a maximum storage capacity of 642,500 acre-feet, and collects water from a drainage area of 232 square miles. Completed in 1986, the structure is 40 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.
