Mill - Canton Creek W/s Str. #12 Dam

About Mill - Canton Creek W/s Str. #12 Dam

The primary purpose of Mill - Canton Creek W/s Str. #12 Dam 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 Soil And Water Conservation District (state). It impounds the Unnamed Tributary near Canton.

The dam stands 36 feet tall and stretches 490 feet across, creates a reservoir covering 16 acres, and has a maximum storage capacity of 585 acre-feet. Completed in 1965, 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. Notably, no emergency action plan is currently on file for this high-hazard dam. The most recent inspection on record was 09/01/1999. That was 26 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.

At 36 feet, this dam is taller than 83% of dams nationwide.
