About Tumco Dam Ai-50
The primary purpose of Tumco Dam Ai-50 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 Txu Mining Company Lp (private). It impounds the Caney Branch.
The dam stands 14 feet tall and stretches 2,550 feet across, creates a reservoir covering 21 acres, has a maximum storage capacity of 357 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1995, the structure is 31 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.
