About this map

Morgan Harbor and the surrounding marshlands of Saint Bernard Parish are defined by a complex network of coastal waterways where the Mississippi River delta meets the Gulf of Mexico. This 2018 survey illustrates a landscape dominated by shifting tidal channels and isolated landforms, including Comfort Island and Dry Bread Island. The area is characterized by major water bodies such as Eloi Bay and Chandeleur Sound, which are connected by vital maritime passages like Morgan Harbor Pass and Scow Pass.

Inland, the hydrology is shaped by winding bayous, most notably Bayou La Loutre and Martinbox Bayou, which serve as the primary drainage and navigation arteries through the wetland. Features like Codfish Point and Point Eliza mark the precarious edges of the marsh, while Treasure Bay Pass suggests the historical and commercial importance of these routes for local fishing and coastal transit. The map provides a precise view of the coastal topography before further subsidence and erosion continue to reshape the Louisiana shoreline.
