In the 1970s, the U.S. Army Corps of Engineers’ Lake Pontchartrain and Vicinity Hurricane Barrier Project planned to build fortifications at two strategic locations, which would keep massive storms on the Gulf of Mexico from causing Lake Pontchartrain to flood the city of New Orleans. These plans were abandoned after a radical enviromental group called Save Our Wetlands successfully sued to stop the projects as too damaging to the wetlands and the lake's eco-system.
