Does Lake Anna, North Anna nuclear power plant's cooling water supply, have one of Virginia's many "high-hazard dams"?

'The American Society for Civil Engineers’ most recent “report card” on national infrastructure lists a number of trouble spots in Virginia -- including 143 “high-hazard” dams, one of which sits on Lake Anna near the North Anna nuclear power plant.

“A high hazard dam is defined as a dam whose failure would cause a loss of life and significant property damage,” the group notes on its website.'

The Virginia Section of the American Society of Civil Engineers reported in its "2009 Virginia Infrastructure Report Card" that Virginia's dams get a "D minus," tied with roads for its lowest grade for any infrastructure in Virginia.
