About this map

Lake Raccourci and the surrounding marshlands of coastal Lafourche Parish are dominated by an intricate network of waterways and early petroleum development in the mid-1950s. The transition from open water to fragmented marsh is evident across Timbalier Bay and Little Lake, where numerous gas and oil wells are located. A specific point of human activity is noted at Jacko Camp near Jacko Camp Bay, alongside the remnants of ruins on the Philo Brice Islands.

Navigational features characterize the local economy and geography, from the aptly named Wrong Name Pass to the deep channels of Pelican Pass. The coastal fringe is defined by landmasses like Casse-Tete Island and Devils Island, separated by a maze of bayous including Rosa Bayou and Blue Bayou. This survey captures the precarious balance of the Louisiana delta before significant 20th-century coastal erosion altered these boundaries.
