2018 Map of Three Mile Bay

About this map

The coastal marshlands of Saint Bernard Parish are defined by an intricate network of waterways and islands where the land meets the Gulf of Mexico. This environment is anchored by Three Mile Bay and North Karako Bay, showing a landscape dominated by tidal hydrology rather than human infrastructure. Coastal points and small islands like Negro Point, Shell Point, and Raccoon Island serve as critical markers in this low-lying territory. The map reveals the labyrinthine nature of the Louisiana coast, where named passages like Three Mile Pass and numerous bayous, including Turkey Bayou and Drum Bayou, dictate the movement of water and watercraft. Notable landforms such as Crooked Island and Mink Island emerge from the surrounding Bay Boudreau, illustrating the precarious and shifting shoreline of the region. This survey captures the specialized geography of the parish, where navigation through reaches like Bayou Creque and Northwest Jack Williams Bay is essential for understanding the local environment.
