2024 Map of Black Bay South

About this map

The coastal wetlands and expansive water bodies of Plaquemines Parish define this landscape, where the tides of Black Bay meet the intricate network of the Mississippi River delta. This survey documents a fragile environment of scattered landforms and complex hydrology, featuring named points of interest like Lonesome Island and Stone Island. The map illustrates the specialized nautical geography of the region, where narrow passages such as Bel La Pass and Bel Pass Bayou connect larger basins like Whiskey Bay and California Bay. Named landmarks such as Telegraph Point and Curfew Point serve as essential references for navigation through the shifting marshlands. The absence of roads and terrestrial infrastructure emphasizes the maritime character of this area, highlighting the reliance on waterborne transit between Breton Sound and the interior bays. This modern data set serves as a critical reference for understanding the contemporary state of Louisiana's vulnerable coastal perimeter.
