Mississippi Lt Gov: Corps ignored spillway operating manual July 20, 2021 GMT NEW ORLEANS (AP) — The Army Corps of Engineers ignored its own operating manual when it twice opened a Mississippi River spillway in 2019, causing an environmental and economic disaster in Mississippi and Louisiana, Mississippi Lt. Gov. Delbert Hosemann said Tuesday. He spoke on the way to Pass Christian to see endangered sea turtles released after being rehabilitated in Mississippi from cold-stunning in New England, and said he planned to bring up the topic then.

Gov. Billy Nungesser.
