U.S. Army Corps Closes Bays At The Bonnet Carré Spillway
The U.S. Army Corps of Engineers, New Orleans District, began closing bays at the Bonnet Carré Spillway on July 22. The decision came after they found reduced flows in the Mississippi River at Red River Landing.
The Corps said it would initially close 10 of the 168 bays that had been opened. The Corps continues to assess conditions of the Mississippi River and perform closure operations based upon these conditions, according to a press release.
What You Need To Know
The Bonnet Carré Spillway is designed to ensure that a maximum river flow of 1.25 million cubic feet per second (cfs) is passed through Mississippi River and Tributaries system at New Orleans, according to the Corps. Because the river has receded below the maximum flow at Red River Landing, the diversion of water into Lake Pontchartrain is no longer needed to safely pass the river flow through the New Orleans area.
Monday, July 22nd, marked the 74 day the structure has been opened during the latest operation. They say during the peak 161,000 cfs was being diverted through the flood control structure. This operation marks the first time the structure has been operated twice in one year and the first time it has been operated in back-to-back years.
Although water levels are receding, allowing the structure’s closure, the Mississippi River in the New Orleans District’s area of responsibility remains elevated.
