About Tumco Dam Di-16
The primary purpose of Tumco Dam Di-16 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 Tr-mill Creek.
The dam stands 18 feet tall and stretches 425 feet across, creates a reservoir covering 11 acres, has a maximum storage capacity of 265 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1992, the structure is 34 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.
