About this map

Grand Isle and the intricate coastal wetlands of the Mississippi River Delta are documented here as they appeared in 2020. This fragile aquatic landscape is defined by the Southwest Pass and a network of minor outlets such as Outlet E-1 and Outlet W-1, which facilitate the exchange of water across the marsh. The survey illustrates the complex relationship between land and sea, where named features like Cockler Point and Cockler Bay serve as landmarks in an area dominated by open water and narrow distributaries.

The northern reaches are characterized by sheltered bays, including Caminada Bay, Zinzin Bay, and Riverside Bay. These water bodies are separated by tidal passages such as Caminada Pass. To the south and west, the map transitions into the expansive West Bay and East Bay, interrupted only by subtle terrain features like Bayou Saint Honore and Bayou Fort Blanc. This detailed view of Plaquemines Parish provides a snapshot of the delta's current configuration, useful for tracking coastal erosion and changes in the estuary over time.
