Upland Cell Ii Interior

About Upland Cell Ii Interior

The primary purpose of Upland Cell Ii Interior 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 Arcelormittal (private). It impounds the Wouri Creek-os near Virginia.

The dam stands 60 feet tall and stretches 11,000 feet across, creates a reservoir covering 29 acres, has a maximum storage capacity of 4,750 acre-feet, and collects water from a drainage area of 2 square miles. Completed in 2011, the structure is relatively new.

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. The most recent inspection on record was 08/15/2024.

At 60 feet, this dam is taller than 95% of all dams in the United States.
