About Plant 65 Lake Dam
The primary purpose of Plant 65 Lake 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.

It impounds the Unt of Copiah Creek.
The dam stands 39 feet tall and stretches 330 feet across, creates a reservoir covering 7 acres, has a maximum storage capacity of 170 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 2007, the structure is relatively new.
