About Noonday Creek Ws Str # 15

The primary purpose of Noonday Creek Ws Str # 15 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 Cobb County Swcd (state). It impounds the Unknown near Kennesaw (environs).

The dam stands 34 feet tall and stretches 397 feet across, creates a reservoir covering 7 acres, has a maximum storage capacity of 219 acre-feet, and collects water from a drainage area of 455 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 fair — the dam has minor deficiencies that are being addressed or do not pose an immediate safety threat. An emergency action plan is in place for this dam. The most recent inspection on record was 04/07/2017. That was 8 years ago, which is on the longer end for a high-hazard structure.

At 34 feet, this dam is taller than 80% of dams nationwide.
