About Pol31
The primary purpose of Pol31 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 Mosaic Fertilizer Llc (private). It impounds the Unnamed Pond near Mulberry.
The dam stands 62 feet tall and stretches 5,446 feet across, creates a reservoir covering 27 acres, and has a storage capacity of 878 acre-feet.
At 62 feet, this dam is taller than 95% of all dams in the United States.
