About Pol13
The primary purpose of Pol13 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 Fort Meade.
The dam stands 6 feet tall and stretches 18,866 feet across, creates a reservoir covering 172 acres, and has a maximum storage capacity of 9,872 acre-feet.
