Simpson Lake Dam

About Simpson Lake Dam

The primary purpose of Simpson Lake Dam is recreation. The dam creates a reservoir used for recreational activities such as fishing, boating, and swimming. The dam is owned by Kimsey, David Childs, Anita Spring Creek Homeowners' Association (private). It impounds the Unknown near Fortson Environs.

The dam stands 24 feet tall and stretches 580 feet across, creates a reservoir covering 9 acres, has a maximum storage capacity of 109 acre-feet, and collects water from a drainage area of 99 square miles. Completed in 1961, the structure is well into its service life at over 50 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. This classification reflects the consequences of failure, not the likelihood — it indicates that people live or work in the area downstream. Its condition is rated poor, meaning the dam has recognized safety deficiencies that require remediation to address risks. Notably, no emergency action plan is currently on file for this high-hazard dam. The most recent inspection on record was 03/13/2019. That was 7 years ago, which is on the longer end for a high-hazard structure.
