Buck Ash Basin Divider Dam

About Buck Ash Basin Divider Dam

The primary purpose of Buck Ash Basin Divider Dam is tailings. Tailings dams contain waste material from mining operations — typically a slurry of finely ground rock left over after valuable minerals have been extracted. These structures require ongoing monitoring because tailings can contain heavy metals and other contaminants. The dam is owned by Duke Energy Corporation (public utility). It impounds the Yadkin River.

The dam stands 10 feet tall and stretches 1,400 feet across, creates a reservoir covering 46 acres, has a maximum storage capacity of 1,177 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 1977, the structure is 49 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 satisfactory, indicating no existing or potential dam safety deficiencies are recognized. An emergency action plan is in place for this dam. The most recent inspection on record was 11/13/2024.
