About Scs-delaware Creek Site-009

The primary purpose of Scs-delaware Creek Site-009 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 Johnston Co Cons Dist (state). It impounds the Delaware Creek near Cane.

The dam stands 70 feet tall and stretches 1,130 feet across, creates a reservoir covering 67 acres, and has a maximum storage capacity of 4,448 acre-feet. 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. 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 12/19/2011. That was 14 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.

At 70 feet, this dam is taller than 96% of all dams in the United States.
