About Scs-tonkawa Creek Site-001a

The primary purpose of Scs-tonkawa Creek Site-001a 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 South Caddo Cons Dist (state). It impounds the Tonkawa Cr near Anadarko.

The dam stands 44 feet tall and stretches 990 feet across, creates a reservoir covering 9 acres, and has a maximum storage capacity of 333 acre-feet. Completed in 1968, the structure is well into its service life at over 50 years old.

This dam has a significant hazard potential classification, meaning that a failure could cause significant economic damage — flooding roads, bridges, or property downstream — but is not expected to result in loss of life. Its condition is rated fair — the dam has minor deficiencies that are being addressed or do not pose an immediate safety threat. The most recent inspection on record was 08/18/2011. That was over 14 years ago.

At 44 feet, this dam is taller than 90% of dams nationwide.
