1994 Map of Ellerslie

About this map

West Cote Blanche Bay and East Cote Blanche Bay define this coastal landscape, where the marshy terrain of St. Mary Parish is crisscrossed by an intricate network of natural bayous and industrial canals. The mapping reflects a region heavily defined by petroleum extraction, as seen in the expansive Garden City Gas and Oil Field and the Carlin Gas Field. Transportation and water management are central to the area's layout, with the Intracoastal Waterway cutting through the wetlands and a Road on Levee providing land access to the small settlements of Ellerslie and South Bend. The hydrology is complex, featuring named waterways like Black Crook Bayou and Yellow Bayou alongside artificial channels such as Thorguson Canal. This 1990s survey also notes the presence of a Pumping Station and various drill holes, illustrating the ongoing infrastructure required to maintain and utilize this subsidence-prone coastal environment.
