About this map

Lake Pontchartrain dominates this aquatic landscape, providing a clear view of the open waters north of the Mississippi River delta. This survey captures a moment in the early 21st century where the primary focus is the intersection of parish jurisdictions across the lake. The map delineates the shared watery boundaries of St. John the Baptist Parish, St. Charles Parish, and Jefferson Parish. This perspective is particularly useful for understanding the complex legal and administrative divisions of the Louisiana coast, where boundaries are often defined by the surface of the lake itself rather than land-based markers.
