At least 30 bays of the Bonnet Carre Spillway in St. Charles Parish will be opened today by the Army Corps of Engineers to alleviate the flooding threat posed by the Mississippi River.
This is only the 13th time in the structure's history that such an opening of the bays was deemed necessary and it marks the first time that the bays have been opened in consecutive years.
The step diverts some of the river's water into Lake Pontchartrain and lessens the threat to land and levees downstream towards New Orleans.
