Intense rainfall in the wake of Hurricane Helene threatened to breach dams across east Tennessee and western North Carolina in recent days, but structures held despite the pressure.

The Tennessee Valley Authority, the nation’s largest public power utility, confirmed all 49 of its dams remain intact, even as it reported releasing record amounts of water from some facilities.
