About Kingsford K-3
The primary purpose of Kingsford K-3 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 Mizelle Creek near Bradley.
The dam stands 50 feet tall and stretches 9,100 feet across, creates a reservoir covering 260 acres, and has a maximum storage capacity of 13,000 acre-feet. Completed in 1977, the structure is 49 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.
At 50 feet, this dam is taller than 93% of dams nationwide.
