The Army Corps of Engineers will be opening the Bonnet Carré Spillway Friday as early at 1 p.m.
On Thursday the Corps recommended operating the Bonnet Carré Spillway to the Mississippi Valley Division Commanding General with a tentative date of May 14.
Regional rainfall caused the Mississippi River to rise 6 inches in the past 24 hours with more rain expected through the weekend.
These rains could elevate the Mississippi River above 17 feet with a peak as high as 17.5 feet at the Carrollton Gage.
In an abundance of caution the operation date is being moved forward to ensure the safe passage of this high water by limiting the elevations downriver of the spillway, according to the Corps.
Operation of the structure will relieve pressure on main levees, maintain river stages, and regulate the flow downriver from the spillway.
The decision to open Bonnet Carré was issued by Maj. Gen. Richard G. Kaiser commander of the Mississippi Valley Division in Vicksburg, Miss.
This will be the 14 operation of the structure since 1937 and the first time it has been opened twice during the same high water event.
