Ni 2 (nichols)

About Ni 2 (nichols)

The primary purpose of Ni 2 (nichols) 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 Alafia Llc (private). It impounds the See Remarks near Mulberry.

The dam stands 43 feet tall and stretches 13,800 feet across, creates a reservoir covering 250 acres, and has a maximum storage capacity of 6,000 acre-feet. Completed in 1973, the structure is well into its service life at over 50 years old.

This dam carries a high hazard potential classification, which means that a failure or uncontrolled release of water would likely cause loss of human life. This classification reflects the consequences of failure, not the likelihood — it indicates that people live or work in the area downstream. Notably, no emergency action plan is currently on file for this high-hazard dam. The most recent inspection on record was 10/16/2014. That was 11 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.

At 43 feet, this dam is taller than 89% of dams nationwide.
