Corps working on maps to detail flooding from opening spillway to ease pressure on Mississippi River

BATON ROUGE -- The U.S. Army Corps of Engineers New Orleans District continues to work with local officials to develop more detailed flooding maps that would detail the likely consequences of opening the Morganza Spillway north of Baton Rouge, a corps official said Monday.

State officials, meanwhile, continue widespread preparation efforts that range from placing sandbags and inspecting sandbags to moving inmates from the Louisiana State Penitentiary at Angola. The Morganza has not been opened since 1973. The Corps began opening the Bonnet Carre Spillway in New Orleans on Monday morning.

The Corps released Morganza inundation maps Friday, but those don't yet include details about how many residences and other structures could be affected in and around the Atchafalaya Basin. Col. Mark D. Jernigan, deputy commander of the New Orleans District, said the corps is leaning on local levee districts and other agencies for those detailed projections.

"We're working the numbers right now," he said.
