About Cs-11
The primary purpose of Cs-11 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 The Mosaic Company (private). It impounds the Peace River near Fort Meade.
The dam stands 6 feet tall, creates a reservoir covering 7,167 acres, and has a maximum storage capacity of 43,000 acre-feet.
This dam has a significant hazard potential classification, meaning that a failure could cause significant economic damage — flooding roads, bridges, or property downstream — but is not expected to result in loss of life.
