Lake Pontchartrain dominates this maritime survey, illustrating the vast open waters north of New Orleans in the mid-2010s. The map provides a focused look at the convergence of three jurisdictional boundaries—St. Tammany Parish, Jefferson Parish, and Orleans Parish—which meet within the lake's basin. This intersection highlights the complex administrative geography of the region, where water often serves as the primary dividing line between coastal parishes. In the northwest corner, the Lake Pontchartrain Causeway is visible as it begins its long transit across the water, representing a critical engineering link for the metropolitan area. The absence of landmass on this sheet emphasizes the importance of the lake as a central geographical feature and a boundary-defining element for the surrounding communities.
