Lake Borgne is a saltwater bay in southeastern Louisiana. About 25 miles (40 km) long, it is the western end of Mississippi Sound, an arm of the Gulf of Mexico. There are many oil wells in its waters. Lake Borgne is connected on the west with Lake Ponchartrain by the Rigolets, a navigable passage, and with the Mississippi River at New Orleans by the Intracoastal Waterway.
