About Scs-big Wewoka Creek Site-29

The primary purpose of Scs-big Wewoka Creek Site-29 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 Seminole County Conservation District (state). It impounds the Tributary Of Wewoka Creek near Wetumka.

The dam stands 41 feet tall and stretches 1,000 feet across, creates a reservoir covering 19 acres, has a maximum storage capacity of 781 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1958, 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 11/04/2011. That was 14 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.

At 41 feet, this dam is taller than 88% of dams nationwide.
