1974 Map of Lost Lake

About this map

Lost Lake dominates this coastal Louisiana landscape, where the tides of Fourleague Bay meet a complex network of marshland waterways in Terrebonne Parish. This mid-1970s orthophotomap provides a rare hybrid view of the delta, combining traditional topographic surveying with high-altitude aerial photography to reveal the intricate boundaries between land and water. Key navigational features such as Lost Lake Pass and The Narrows connect larger bodies like Lake Mechant and Carencro Lake. The influence of the oil and gas industry is evident through scattered Gas Wells and pipelines that cut across the wetland. Notable landmarks like Rice Island and Blue Hammock Bayou highlight the specific geography of the region before decades of significant coastal change altered the shoreline.
