About Boyette Sa-2
The primary purpose of Boyette Sa-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 The Mosaic Company (private). It impounds the Hurrah Creek near Boyette.
The dam stands 15 feet tall and stretches 8,900 feet across, creates a reservoir covering 167 acres, and has a maximum storage capacity of 2,500 acre-feet. Completed in 1951, 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.
