Flood update from downriver - river reopened to traffic

The U.S. Army Corps of Engineers (USACE) in New Orleans announced about 10 a.m. (CDT) that 16 gates have been opened at the Morganza Spillway  flood control structure. A flow of 108,000 cubic feet per second  is now being diverted from the main channel of the Mississippi River.

There are 125 gates at Morganza and the Corps expects to eventually open between 30 and 35 of them.

The flooding being created by the spillway's opening on Saturday has been slowed by the extreme drought conditions plaguing that part of the state./ The New Orleans District of the corps announced 16 gates have been opened at the Morganza spillway, moving water through the structure at an estimated 108,000 cubic feet per second.   Morganza has 125 total gates.   The corps began opening them slowly on Saturday.

About 115 river miles to the south, 330 of the 350 gates at the Bonnet Carre' Spillway are open at Norco, diverting water from the river into Lake Pontchartarin in an effort to keep the levees from being overtopped in the Crescent City.

USACE also announced earlier today that it was opening the Mississiippi to traffic north of New Orleans. On Tuesday, the Corps had closed the river at Natchez.
