About Mosaic Csa Bf3
The primary purpose of Mosaic Csa Bf3 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 52 feet tall and stretches 15,400 feet across, creates a reservoir covering 407 acres, has a maximum storage capacity of 19,500 acre-feet, and collects water from a drainage area of 65 square miles. Completed in 1984, the structure is 42 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. An emergency action plan is in place for this dam. The most recent inspection on record was 07/20/2005. That was over 20 years ago.
At 52 feet, this dam is taller than 93% of dams nationwide.
