About Sedimentation Pond No 18
The primary purpose of Sedimentation Pond No 18 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 West Morelan Coal (private). It impounds the Lambs Creek.
The dam stands 18 feet tall, creates a reservoir covering 52 acres, has a maximum storage capacity of 825 acre-feet, and collects water from a drainage area of 6 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.
