360 degree aerial panorama shot from a helicopter 400 feet above the Rigolets Pass in southern Louisiana after Hurricane Katrina. This is where Lake Pontchatrain connects to Lake Borgne and the Gulf of Mexico.

The U.S. Army Corp of Engineers planned to build hurricane barriers at the Rigolets and Chef Menteur passes to prevent storm surges from reaching Lake Pontchatrain and flooding New Orleans. But in 1977 an environmental group sued because of the possible damage to the area ecosystem.
