About Area C
The primary purpose of Area C 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 Brewster.
The dam stands 22 feet tall and stretches 18,150 feet across, creates a reservoir covering 786 acres, and has a maximum storage capacity of 9,360 acre-feet. Completed in 1969, the structure is well into its service life at over 50 years old.
This dam has a low hazard potential classification, meaning that failure would cause minimal damage, limited primarily to the dam owner's property, with no expected loss of life.
