About Scs-bear Hybarger Site-4

The primary purpose of Scs-bear Hybarger Site-4 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 Garvin Co Cons Dist (state). It impounds the Tr-hybarger Creek near Lindsay.

The dam stands 28 feet tall and stretches 1,000 feet across, creates a reservoir covering 2 acres, and has a maximum storage capacity of 89 acre-feet. Completed in 1965, 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 10/24/2011.
