About Noralyn N-13
The primary purpose of Noralyn N-13 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 Camp Creek near Bartow.
The dam stands 25 feet tall and stretches 4,800 feet across, creates a reservoir covering 260 acres, and has a maximum storage capacity of 6,500 acre-feet. Completed in 1978, the structure is 48 years old.
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.
