About Scs-sallisaw Creek Site -33
The primary purpose of Scs-sallisaw Creek Site -33 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 Sequoyah County Conservation District (state). It impounds the Hog Creek near Sallisaw.
The dam stands 58 feet tall and stretches 1,700 feet across, creates a reservoir covering 44 acres, has a maximum storage capacity of 1,280 acre-feet, and collects water from a drainage area of 2 square miles. Completed in 1966, 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. An emergency action plan is in place for this dam. The most recent inspection on record was 01/01/2011. That was 15 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.
At 58 feet, this dam is taller than 95% of all dams in the United States.
