About Peace River
The primary purpose of Peace River 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 14 feet tall and stretches 12,000 feet across, creates a reservoir covering 270 acres, and has a maximum storage capacity of 3,780 acre-feet. Completed in 1945, the structure is well-established, with more than 75 years of service.
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.
