About Kingsford O South
The primary purpose of Kingsford O South 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 Keysville.
The dam stands 17 feet tall and stretches 8,575 feet across, creates a reservoir covering 70 acres, has a maximum storage capacity of 800 acre-feet, and collects water from a drainage area of 0 square miles. 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. The most recent inspection on record was 01/20/2006. That was over 20 years ago.
