About this map

The Intracoastal Waterway serves as a critical navigation artery across this coastal Cameron Parish landscape, cutting through the marshlands north of Grand Lake. This environment is defined by a complex mosaic of open water and low-lying landforms, including Oak Island and Perreau Island. To the south, the expansive Mallard Bay and Umbrella Bay dominate the geography, fed by a network of engineered and natural channels like Lulu Canal and Latanier Ditch.

Remote water bodies such as Lake Monzelum, Floating Lake, and Willow Lake illustrate the semi-aquatic nature of the region. Human infrastructure is limited to the northern fringes, where Broussard RD and Parish RD 113 provide access to the edges of Maple Marsh. The presence of features like Five Bayou Cypress and Shell Island highlights the intricate, shifting shoreline that characterizes this part of the Louisiana coast.
