On September 15, 1993, a pipeline owned by NORCO, Inc., and formerly owned and operated by ARCO, Inc. ruptured, discharging an estimated 676 barrels (30,000 gallons) of #2 diesel fuel into a crop field in DeKalb County, Indiana. The diesel fuel made its way into a small drainage ditch that discharges to Fish Creek. This oil entered Fish Creek and spread downstream, crossing into Williams County, Ohio, exposing the lower 7 miles of the creek to the diesel fuel contamination.
