About Kingston No. 1 Dam
The primary purpose of Kingston No. 1 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 private-owned. It impounds the Tr-mineral Fk-big River near Bliss.
The dam stands 85 feet tall and stretches 1,475 feet across, creates a reservoir covering 60 acres, has a maximum storage capacity of 1,700 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 1967, 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. Its condition is rated satisfactory, indicating no existing or potential dam safety deficiencies are recognized. An emergency action plan is in place for this dam. The most recent inspection on record was 11/04/2020.
At 85 feet, this dam is taller than 97% of all dams in the United States.
