About this map

Three Mile Bay and its intricate network of coastal waterways define this marshy landscape in Saint Bernard Parish. The area is a complex environment of bayous and islands, where the land is fragmented into dozens of survey sections. Prominent coastal features like 7 Negro Point and Shell Point mark the transition from open water into the narrower channels of Turkey Bayou and Drum Bayou.

Navigation through this maritime environment relies on natural landmarks such as Little Raccoon Island and Mink Island. The presence of named passages like Three Mile Pass and numerous smaller bays, including Northwest Jack Williams Bay, indicates a landscape primarily shaped by tidal flow and coastal erosion. The lack of terrestrial infrastructure highlights the region's character as a specialized wetland environment where traditional roads are absent, replaced by a maze of inlets like Picnic Bayou and Bay Boudreau.
