About Clay Settling Area Bl
The primary purpose of Clay Settling Area Bl 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 South Prong Alafia River near Fish Hawk.
The dam stands 27 feet tall and stretches 10,200 feet across, creates a reservoir covering 181 acres, and has a maximum storage capacity of 4,900 acre-feet. Completed in 1979, the structure is 47 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.
