2020 Map of Three Mile Bay
USGS Topo · Published 2020About this map
Three Mile Bay and its intricate network of coastal inlets define this portion of the Louisiana marshland in Saint Bernard Parish. The landscape is dominated by tidal waterways and small, low-lying landmasses such as Little Raccoon Island, Raccoon Island, and Mink Island. The presence of numerous named bayous, including Turkey Bayou and Picnic Bayou, suggests a complex hydraulic system where freshwater runoff meets the Gulf tides. These features reflect the geomorphology of the Mississippi River delta, where land and water exist in a state of constant transition. Points like Shell Point and Negro Point serve as landmarks in an area otherwise characterized by vast stretches of open water like Bay Boudreau and North Karako Bay.
