About Yellow River Rc&d Ws Str. Y-3

The primary purpose of Yellow River Rc&d Ws Str. Y-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 Gwinnett County Board Of Commissioners Gwinnett County Swcd (state). It impounds the Unknown near Gloster.

The dam stands 36 feet tall and stretches 750 feet across, creates a reservoir covering 12 acres, and has a maximum storage capacity of 495 acre-feet. Completed in 1967, 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 satisfactory, indicating no existing or potential dam safety deficiencies are recognized. An emergency action plan is in place for this dam. The most recent inspection on record was 01/27/2016. That was 10 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.

At 36 feet, this dam is taller than 83% of dams nationwide.
