About Fort Green Fg-2
The primary purpose of Fort Green Fg-2 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 The Mosaic Company (private). It impounds the Payne Creek near Fort Green.
The dam stands 23 feet tall and stretches 13,730 feet across, creates a reservoir covering 528 acres, and has a maximum storage capacity of 12,144 acre-feet. Completed in 1977, the structure is 49 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.
