About Har3
The primary purpose of Har3 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 Wauchula.
The dam stands 7 feet tall and stretches 15,110 feet across, creates a reservoir covering 357 acres, and has a maximum storage capacity of 10,712 acre-feet.
