2025 Map of Garden Island Pass

USGS Topo · Published 2025

About this map

Old Balize Bayou and the surrounding marshlands of Plaquemines Parish represent the final, shifting fingers of the Mississippi River delta as it reaches the Gulf of America. This 2025 survey documents the ephemeral nature of the Louisiana shoreline, where deep-water channels like Southeast Pass and Mississippi Bayou carve through a landscape of shallow bays and small landforms. Historical maritime researchers will find the location of Garden Island Pass and Lookout Island critical for understanding the evolving navigation routes into the Gulf. The map illustrates a world defined by hydrology, from the sheltered waters of North Shore Bay to the exposed reaches of Redfish Bay and Garden Island Bay, showing a coastal environment in constant flux.
