About Kingsford Csa Dl
The primary purpose of Kingsford Csa Dl 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 Bradley Junction.
The dam stands 27 feet tall and stretches 16,125 feet across, creates a reservoir covering 485 acres, has a maximum storage capacity of 10,500 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 1971, the structure is well into its service life at over 50 years old.
