About Lonesome Rougher Water Pond
The primary purpose of Lonesome Rougher Water Pond 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 Picnic.
The dam stands 22 feet tall and stretches 2,600 feet across, creates a reservoir covering 18 acres, and has a maximum storage capacity of 400 acre-feet. Completed in 1976, the structure is 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.
