About Marathon Brine Pond Dam
The primary purpose of Marathon Brine 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 Marathon Petroleum Co. Lp. It impounds the Unnamed Tributary To Hurford Run near Canton.
The dam stands 23 feet tall and stretches 1,400 feet across, creates a reservoir covering 3 acres, and has a maximum storage capacity of 53 acre-feet. Completed in 2008, the structure is relatively new.
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 05/13/2025.
