Pond No 1

About Pond No 1

The primary purpose of Pond No 1 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 General Crushed Stone Company (private). It impounds the Tr Valley Creek.

The dam stands 71 feet tall and stretches 3,950 feet across, creates a reservoir covering 13 acres, has a maximum storage capacity of 1,000 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 fair — the dam has minor deficiencies that are being addressed or do not pose an immediate safety threat. The most recent inspection on record was 05/15/2007. That was over 18 years ago.

At 71 feet, this dam is taller than 96% of all dams in the United States.
