1932 Map of Bayou Blanc

About this map

Marsh Island is depicted here as an intricate mosaic of wetlands and tidal waters at the edge of the Iberia Parish coast. The terrain is defined by a dense network of water bodies, including Lake Blanc, Lake Michael, and the elongated Lake Sand, which are linked by winding waterways like Bayou Blanc. The map reveals a landscape heavily shaped by coastal hydrology, where West Branch Oyster Bayou and its eastern counterpart drain into the Gulf of Mexico. Along the southern shoreline, distinctive landmarks such as Mound Point and South Point offer evidence of geographical relief in an otherwise low-lying environment. This survey captures the island before significant modern alterations, showing the complex natural channels and interior lakes like Lake Ferme and Oyster Lake that have long dictated the movement of wildlife and people through the Louisiana marshlands.
