Morganza spillway

Though the official decision will not be made until next week, the Army Corps of Engineers expects to open the Morganza Spillway as soon as June 2nd.

Located upriver from Baton Rouge, the Spillway has only been used twice before: during the floods of 1973 and 2011.

 

Whereas the Bonnet Carre Spillway relieves pressure on the Mississippi River by diverting excess water into Lake Pontchartrain, Morganza eventually empties into the Atchafalaya Basin.
