About Young Mill Tailings Dam
The primary purpose of Young Mill Tailings Dam 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 Nyrstar Tn Mines-strawberry Plains (private).
The dam stands 70 feet tall and stretches 550 feet across, creates a reservoir covering 22 acres, has a maximum storage capacity of 474 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 2002, the structure is relatively new.
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 70 feet, this dam is taller than 96% of all dams in the United States.
