About Hil8
The primary purpose of Hil8 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 Mosaic Fertilizer Llc (private). It impounds the Unnamed Pond near Tampa.
The dam stands 44 feet tall and stretches 5,388 feet across, creates a reservoir covering 36 acres, and has a storage capacity of 277 acre-feet.
At 44 feet, this dam is taller than 90% of dams nationwide.
