About this map

The low-lying coastal marshes of Jefferson and Plaquemines Parishes are defined by a complex network of waterways and shifting shorelines. The settlement of Manilla sits at the edge of this amphibious landscape, where the Barataria Bay Waterway cuts a straight path through the natural curves of the delta. This 2015 survey illustrates how the land dissolves into the Gulf of Mexico, with prominent landmarks like Saint Marys Point, Big Island, and Grand Island Point marking the transition from marsh to open water.

Hydrological features dominate the area, including the namesake Wilkinson Bay and its connected Wilkinson Bayou. To the west, Mud Lake and Bayou Saint Denis feed into the larger system, while Bay Chene Fleur and Bay Jimmy create a fragmented geography typical of the Louisiana coast. The map clearly delineates the boundary between Jefferson Parish and Plaquemines Parish, providing a precise look at the jurisdictional lines in an area where solid ground is at a premium.
