LESTERVILLE, Mo. — A dam in rural southeast Missouri failed Wednesday morning after a night of heavy rain and one person was missing in what officials called a "very dangerous situation."
A family of five was rescued after the Upper Taum Sauk Lake Dam failed at about 6:24 a.m., Reynolds County Sheriff's dispatcher Ginger Bell said. The National Weather Service warned that conditions along the Black River were creating a "dangerous and life-threatening situation." Residents of Lesterville and elsewhere downstream from the dam were urged to move quickly to higher ground.
Small creeks and streams, country roads and farmland will be flooded, the agency said. The dam is in the Ozarks, about 120 miles southwest of St. Louis. Reynolds County has a population of about 6,700
