About Sa 9 S.c

The primary purpose of Sa 9 S.c 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 Pcs Phosphate (private). It impounds the Swift Creek near Ellaville.

The dam stands 50 feet tall and stretches 17,900 feet across, creates a reservoir covering 664 acres, has a maximum storage capacity of 30,000 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 2005, the structure is relatively new.

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. An emergency action plan is in place for this dam. The most recent inspection on record was 09/07/2005. That was over 20 years ago.

At 50 feet, this dam is taller than 93% of dams nationwide.
