Pumpkinvine Creek W/s Str. # 3

About Pumpkinvine Creek W/s Str. # 3

The primary purpose of Pumpkinvine Creek W/s Str. # 3 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 Coosa River Swcd (state). It impounds the Griffin Creek near Dallas.

The dam stands 40 feet tall and stretches 435 feet across, creates a reservoir covering 9 acres, has a maximum storage capacity of 544 acre-feet, and collects water from a drainage area of 1,100 square miles. Completed in 1955, 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. An emergency action plan is in place for this dam. The most recent inspection on record was 01/12/2017. That was 9 years ago, which is on the longer end for a high-hazard structure.

At 40 feet, this dam is taller than 87% of dams nationwide.
