Long Canyon Process Pond Dam

About Long Canyon Process Pond Dam

The primary purpose of Long Canyon Process Pond Dam 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 Nevada Gold Mines Llc (private). It impounds the N/a.

The dam stands 15 feet tall and stretches 900 feet across, creates a reservoir covering 5 acres, and has a maximum storage capacity of 80 acre-feet. Completed in 2016, the structure is relatively new.

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 09/03/2021.
