About Saddle Creek Sa-1
The primary purpose of Saddle Creek Sa-1 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 Saddle Creek near Lakeland.
The dam stands 26 feet tall and stretches 21,700 feet across, creates a reservoir covering 416 acres, and has a maximum storage capacity of 10,815 acre-feet. Completed in 1955, the structure is well into its service life at over 50 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.
