About Fmc Granger Tailings Pond Phases 1e -1j
The primary purpose of Fmc Granger Tailings Pond Phases 1e -1j is tailings.

The dam stands 28 feet tall and stretches 11,000 feet across, creates a reservoir covering 1,020 acres, has a maximum storage capacity of 21,800 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 2013, the structure is relatively new.
