Allatoona Dam - Saddle Dike 2a

About Allatoona Dam - Saddle Dike 2a

The primary purpose of Allatoona Dam - Saddle Dike 2a 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 Usace - Mobile District (federal).

The dam stands 15 feet tall and stretches 270 feet across, creates a reservoir covering 11,862 acres, has a maximum storage capacity of 886,200 acre-feet, and collects water from a drainage area of 1,122 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. An emergency action plan is in place for this dam. The most recent inspection on record was 03/26/2019. That was 7 years ago, which is on the longer end for a high-hazard structure.
