About Pol18
The primary purpose of Pol18 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 92 feet tall and stretches 9,236 feet across, creates a reservoir covering 27 acres, and has a storage capacity of 266 acre-feet.
At 92 feet, this dam is taller than 98% of all dams in the United States.
