About Sedimentation Pond No 11 Stage 2
The primary purpose of Sedimentation Pond No 11 Stage 2 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 Texas Westmoreland Coal Co (private). It impounds the Red Hollow Drive.
The dam stands 20 feet tall, creates a reservoir covering 7 acres, has a maximum storage capacity of 193 acre-feet, and collects water from a drainage area of 28 square miles.
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.
