About Pol54
The primary purpose of Pol54 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 Mulberry.
The dam stands 6 feet tall and stretches 5,906 feet across, creates a reservoir covering 40 acres, and has a maximum storage capacity of 1,122 acre-feet.
