Floodwaters on Friday breached a dam that contains a man-made lake connected to a Duke Energy power plant in North Carolina, possibly causing coal ash to flow into the nearby Cape Fear River, the company said. The floodwaters flowed from Cape Fear River into the northern side of Sutton Lake, an 1,100-acre reservoir built in 1972 to cool the L.V. Sutton Power Station. That water caused breaches in

the dam on the south end of the lake, which was flowing back into the river, Duke Energy said in a press release. The 200-mile Cape Fear River flows into the Atlantic at Wilmington, North Carolina. The Sutton site in Wilmington was home to a coal-fired power plant until 2013, when Duke replaced it with a natural gas power station. Duke dismantled the coal-fired plant by 2017, but the grounds contained about 7 million tons of coal ash in waste pits at the time of its closure. There are still two coal ash basins on site.
