About this map

Lost Lake dominates this coastal Louisiana landscape, situated in a complex network of wetlands and tidal channels in Terrebonne Parish. In the mid-1970s, the area's hydrology was defined by the winding course of Blue Hammock Bayou and the tidal exchange through Lost Lake Pass. The map reveals the early industrial footprint on the marsh, with several Gas Wells and a Drill Hole indicating active energy exploration among the native waterways.

Navigation through the marsh is marked by traditional place names like The Narrows and Plessale Cut, while the southern reaches open into Bay Junop and Mudhole Bay. Water bodies such as Carencro Lake and Fiddlers Lake are connected by a labyrinth of smaller streams like Violin Bayou and Washa Bayou, illustrating the fragile, shifting nature of the Louisiana gulf coast before more modern coastal changes took hold.
