About Pol58
The primary purpose of Pol58 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 10 feet tall and stretches 14,444 feet across, creates a reservoir covering 213 acres, and has a maximum storage capacity of 4,214 acre-feet.
