About Cunningham Flyash Pond
The primary purpose of Cunningham Flyash Pond 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 Hatfield Enterprises (private). It impounds the Dutch Hollow near Dunbar.
The dam stands 31 feet tall and stretches 700 feet across, creates a reservoir covering 14 acres, has a maximum storage capacity of 180 acre-feet, and collects water from a drainage area of 11 square miles. Completed in 1971, the structure is well into its service life at over 50 years old.
This dam has a significant hazard potential classification, meaning that a failure could cause significant economic damage — flooding roads, bridges, or property downstream — but is not expected to result in 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 07/20/2018.
