About Scs-cottonwood Creek Site-55

The primary purpose of Scs-cottonwood Creek Site-55 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 Logan Co Cons Dist (state). It impounds the Tr-spring Creek near Seward.

The dam stands 38 feet tall and stretches 1,030 feet across, creates a reservoir covering 11 acres, and has a maximum storage capacity of 363 acre-feet. Completed in 1973, 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 06/22/2011. That was over 14 years ago.

At 38 feet, this dam is taller than 85% of dams nationwide.
