About Watson Sa No 10
The primary purpose of Watson Sa No 10 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 Bowlegs Creek near Fort Meade.
The dam stands 51 feet tall and stretches 8,600 feet across, creates a reservoir covering 43 acres, and has a maximum storage capacity of 2,200 acre-feet. Completed in 1974, the structure is well into its service life at over 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.
At 51 feet, this dam is taller than 93% of dams nationwide.
