The U.S. Army Corps of Engineers is shutting down a Mississippi River lock and dam as flooding worsens.
Corps spokesman Mike Petersen says Lock and Dam 24 in Clarksville, Missouri, will close to navigation Friday. The river is nearly six feet above flood stage in Clarksville and is expected to rise another three feet by Tuesday.
Heavy recent rains in the upper Midwest have caused the Mississippi and many of its tributaries to rise sharply, causing significant flooding in Iowa, Illinois and in Missouri north of St. Louis. The Mississippi remains below flood stage from St. Louis to the south.
The Corps of Engineers is also activating its Emergency Operations Center in St. Louis, a move that enables the agency to provide personnel and resources to support flood-fighting efforts.
