Lake Thacker

About Lake Thacker

The primary purpose of Lake Thacker is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Robert & Jamie Thacker (private). It impounds the Tr-big Creek near Columbia.

The dam stands 24 feet tall and stretches 1,300 feet across, creates a reservoir covering 38 acres, and has a maximum storage capacity of 458 acre-feet.

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.

Living Downstream

If you live or work downstream of this dam, consider taking these steps: learn your local evacuation routes, check whether your county emergency management office has a dam failure inundation map, and sign up for local emergency alerts. The Alabama dam safety program can provide more specific information about emergency planning for this structure.
