2018 Map of Tiger Island

About this map

The Atchafalaya Basin Floodway dominates this portion of Saint Martin Parish, revealing a complex aquatic landscape where the distinction between land and water is constantly shifting. The interior of the basin is a labyrinth of waterways including Little Bayou Chene, Bayou Boutte, and Bayou Darbonne, which weave around low-lying land masses like Tiger Island and Fisher Island. This 2018 survey illustrates the hydrological management of the region, where wide open waters like Duck Lake and Sixmile Lake are connected by narrow channels such as Duck Lake Pass and Riverside Pass. This area serves as a critical drainage corridor, with the map recording the numerous inlets and coves, such as Willow Cove and Boutte Cove, that characterize the swampy terrain. Small, named islands like Cypress Island and Middle Island sit at the southern edge near the parish boundary, marking the transition toward more open bayou systems.
