About Har9
The primary purpose of Har9 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 Unnamed Pond near Palmetto.
The dam stands 7 feet tall and stretches 14,679 feet across, creates a reservoir covering 388 acres, and has a maximum storage capacity of 11,636 acre-feet.
