About Mccoy/cove Tailings Storage Facility Dam
The primary purpose of Mccoy/cove Tailings Storage Facility 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 Au-reka Gold Corporation (private). It impounds the Reese River-os near Battle Mountain.
The dam stands 140 feet tall and stretches 15,200 feet across, creates a reservoir covering 250 acres, has a maximum storage capacity of 25,000 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 1988, the structure is 38 years old.
