Pixelle Upground Reservoir

About Pixelle Upground Reservoir

The primary purpose of Pixelle Upground Reservoir 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 Pixelle Specialty Solutions, Llc. It impounds the Paint Creek - Offstream near Three Locks.

The dam stands 14 feet tall and stretches 5,200 feet across, creates a reservoir covering 17 acres, has a maximum storage capacity of 257 acre-feet, and collects water from a drainage area of 0 square miles.

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.
