About Es-tech Sa-9
The primary purpose of Es-tech Sa-9 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 Mccullough Creek near Fort Meade.
The dam stands 20 feet tall and stretches 17,424 feet across, creates a reservoir covering 259 acres, and has a maximum storage capacity of 5,185 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.
