About Gavin Bottom Ash Pond
The primary purpose of Gavin Bottom Ash 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 Gavin Power, Llc (public utility). It impounds the Kyger Creek - Offstream near York, W. Va..
The dam stands 26 feet tall and stretches 6,650 feet across, creates a reservoir covering 59 acres, has a maximum storage capacity of 1,530 acre-feet, and collects water from a drainage area of 0 square miles. Completed in 1974, 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. Notably, no emergency action plan is currently on file for this high-hazard dam. The most recent inspection on record was 05/04/2022.
