About Mobil Scrubber Pond
The primary purpose of Mobil Scrubber Pond 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 Alafia River near Nichols.
The dam stands 25 feet tall and stretches 5,800 feet across, creates a reservoir covering 34 acres, and has a maximum storage capacity of 845 acre-feet. Completed in 1975, the structure is well into its service life at over 50 years old.
This dam has a significant hazard potential classification, meaning that a failure could cause significant economic damage — flooding roads, bridges, or property downstream — but is not expected to result in loss of life.
