Mark Bishopric, a managing partner of Three Rivers Outfitters, paddles past the Duke energy Dan River Steam Station Tuesday. Coal ash was leaked into the river below the steam station. The Dan River in Eden, N.C. was running high Tuesday, February 25, 2014. New estimates by a team of experts using a drone say a coal ash pond at Duke Energy's Dan River Steam Station leaked at least 35 million gallons tons of coal ash into the Dan River after a drainage pipe running beneath the coal ash pond failed pouring the substance into the waterway.
