flood control

The Army Corps of Engineers is expected to open the Morganza Flood Control Structure on Sunday to relieve flooding on the Mississippi River. For those who live and work downstream of the spillway, that means it’s time to get ready.

For this story, we’re going to take a trip down the floodway, north to south. We’ll start in the town of Morganza, and end up down near the Gulf, talking to people along the way.

The Army Corps of Engineers has delayed the opening of the Morganza Flood Control Structure for a second time.

The Corps was originally set to begin opening the structure on Sunday, June 2nd, but later postponed until Thursday, June 6th. Now the Corps is aiming for Sunday, June 9th.

Officials say changing river forecasts are responsible for both delays. The river is not expected to reach the trigger point for operation until a few days later.

Heavy rains in the Midwest have caused the Mississippi River to swell. To relieve pressure on local levees, the Army Corps of Engineers will begin operating the Bonnet Carre Spillway in Norco on Wednesday.

The levees near New Orleans are only built to handle water moving at 1.25 million cubic feet per second -- quick enough to fill the Superdome in about a minute, the Corps estimates. When the river gets going that fast the Corps opens the spillway, diverting some of that water into Lake Pontchartrain.
