About Duckwood Tailings Storage Facility

The primary purpose of Duckwood Tailings Storage Facility 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 Haile Gold Mine Inc (private). It impounds the Tr-camp Branch Offstream.

The dam stands 110 feet tall, creates a reservoir covering 396 acres, and has a maximum storage capacity of 13,943 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. Its condition is rated fair — the dam has minor deficiencies that are being addressed or do not pose an immediate safety threat. An emergency action plan is in place for this dam. The most recent inspection on record was 08/25/2023.

At 110 feet, this dam is taller than 98% of all dams in the United States.
