Major spillway of rain-swollen Mississippi River opened as a safeguard for New Orleans area
NEW ORLEANS — The U.S. Army Corps of Engineers opened a major spillway Sunday near New Orleans for the first time in nearly five years, seeking to decrease the vast flow of the swollen Mississippi River as a safeguard to the low-lying city.
. . . . The Army Corps of Engineers’ New Orleans District commander had said Tuesday that he was confident the high Mississippi River will pass safely through Louisiana to the Gulf of Mexico.

The Advocate – Army Corps of Engineers: No decision yet on opening Morganza; Corps says opening it would not cause additional flooding in Atchafalaya Basin
” . . . The spillway diverts water from the Mississippi River north of Baton Rouge into the Atchafalaya Basin.
If they do open the spillway, the Corps does not believe it will cause any additional flooding in the Atchafalaya Basin, Boyett [ chief of public affairs of the Corps’ New Orleans District] said.
The Corps’ projections show water will hit about the same levels as the 2011 flooding reached in the basin regardless of whether water from the Mississippi is diverted through the spillway into that area, he said.
Flooding in the basin caused by high water on the Red River should subside just as water from the Mississippi begins pouring into it from the Morganza Spillway if it’s opened, Boyett said. . . “
