Sherman Group Tailings

About Sherman Group Tailings

The primary purpose of Sherman Group Tailings 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 Rggs Land & Minerals Ltd. (private). It impounds the Dempsey Creek-os.

The dam stands 48 feet tall and stretches 2,200 feet across, creates a reservoir covering 168 acres, has a maximum storage capacity of 720 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 1970, the structure is well into its service life at over 50 years old.

This dam has a low hazard potential classification, meaning that failure would cause minimal damage, limited primarily to the dam owner's property, with no expected loss of life. Its condition is rated satisfactory, indicating no existing or potential dam safety deficiencies are recognized. The most recent inspection on record was 07/19/2012. That was over 13 years ago.

At 48 feet, this dam is taller than 92% of dams nationwide.
