About this map

Lake Pontchartrain dominates this aquatic landscape, providing a specialized look at the convergence of three Louisiana parishes within the open water. The map primarily documents the jurisdictional boundaries of St. Tammany Parish, Tangipahoa Parish, and St. John the Baptist Parish. Because the majority of the area is submerged, the survey focuses on the precise intersection of these parish lines in the western reaches of the lake. Small portions of the shoreline appear at the very edges of the quadrangle, illustrating the transition from land to the wide expanse of the lake. This specific edition is based on data compiled by the U.S. Geological Survey using modern imagery and hydrography standards.
