Mulberry Island and its surrounding marshlands characterize this coastal stretch of Vermilion Parish, where the land fragmentizes into the Gulf of Mexico. The landscape is defined by extensive hydrographic engineering, most notably the Dewitt Canal, which cuts through the wetland sections to provide navigation and drainage across the coastal prairie. The survey details the Public Land Survey System grid, including boundaries for t16s r1w, t16s r1e, and t17s r1e, illustrating how traditional land divisions overlay this fluid environment. This 2024 data reflects the contemporary state of Louisiana's receding coastline and the man-made waterways essential to the region's industrial and environmental management.
