Conner Run Refuse Impoundment

About Conner Run Refuse Impoundment

The primary purpose of Conner Run Refuse Impoundment 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 American Electric Power (public utility). It impounds the Conner Run near Wheeling.

The dam stands 267 feet tall and stretches 1,400 feet across, creates a reservoir covering 155 acres, has a maximum storage capacity of 15,750 acre-feet, and collects water from a drainage area of 1 square miles. Completed in 1976, the structure is 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 10/07/2013. That was 12 years ago — unusually long for a high-hazard dam, which typically requires more frequent inspections.

At 267 feet, this dam is taller than 99% of all dams in the United States.
