About Ten Mile Pond #3 Dam
The primary purpose of Ten Mile Pond #3 Dam 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 Climax Molybdenum (private).
The dam stands 416 feet tall and stretches 4,640 feet across, and has a maximum storage capacity of 152,703 acre-feet.
This dam carries a high hazard potential classification, which means that a failure or uncontrolled release of water would likely cause loss of human life. This classification reflects the consequences of failure, not the likelihood — it indicates that people live or work in the area downstream. An emergency action plan is in place for this dam.
At 416 feet, this dam is taller than 99% of all dams in the United States.
