About Settling Area B Dike
The primary purpose of Settling Area B Dike 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 Whidden Creek near Fort Meade.
The dam stands 35 feet tall and stretches 9,660 feet across, creates a reservoir covering 71 acres, and has a maximum storage capacity of 2,500 acre-feet. Completed in 1965, 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 35 feet, this dam is taller than 80% of dams nationwide.
