NEW ORLEANS, LA (WVUE) - The Old River Overbank Structure, southeast of Alexandria, was opened today to relieve pressure on other structures down river.
The Army Corps of Engineers opened the structure because it said the Mississippi River was projected to reach the trigger of 52 feet today at the Knox Landing gage.
"This operation is one of our lessons learned from the 2011 flood that we have incorporated into our emergency response efforts," Mike Stack, Chief of the New Orleans District Emergency Management said. "By opening the Overbank Structure now, we are adding another tool to help ensure we safely pass the required flow through the Old River Control Complex."
The Corps says the Overbank Structure is only operated during high water events. The last time it was operated was in 2013, when the Corps says water flow reached a maximum of 3,000 cubic feet per second during a 16-day opening.
The Overbank Structure is one of the three Old River Control Complex structures designed to distribute river water between the Mississippi and the Atchafalaya at a 70/30 ratio.
