2024 Map of Alligator Point

About this map

New Orleans territory along the eastern coastal margins is defined by a complex network of brackish bayous and tidal lakes where the land dissolves into the Gulf of Mexico. The landscape is dominated by the Intracostal Waterway, which cuts through the marshy terrain to connect Lake Saint Catherine and Lake Catherine with the open waters of Lake Borgne. This contemporary survey illustrates the persistent boundary between Orleans Parish and St. Bernard Parish, a line that meanders through shifting wetlands and across open water south of Shell Point. From Truloix Point in the north down to Alligator Point, the map reveals a fragile geography of points and passes, including Unknown Pass and Blind Bayou, that have shaped the navigational history of this coastal reach.
