Sharp Mountain Creek W/s Str. #22

About Sharp Mountain Creek W/s Str. #22

The primary purpose of Sharp Mountain Creek W/s Str. #22 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 Limestone Valley Swcd (state). It impounds the Polecat Branch near Highway 143 Community.

The dam stands 48 feet tall and stretches 483 feet across, creates a reservoir covering 16 acres, has a maximum storage capacity of 2,099 acre-feet, and collects water from a drainage area of 2,357 square miles. Completed in 1970, 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 poor, meaning the dam has recognized safety deficiencies that require remediation to address risks. An emergency action plan is in place for this dam. The most recent inspection on record was 01/25/2017. That was 9 years ago, which is on the longer end for a high-hazard structure.

At 48 feet, this dam is taller than 92% of dams nationwide.
