Lake Pontchartrain dominates this 2018 survey, which focuses primarily on the open waters where several parish boundaries converge. This specific section of the lake serves as a geographic junction point where the borders of Tangipahoa Parish and St. Tammany Parish meet. Further south, the map delineates the shared boundary of Tangipahoa Parish and St. John the Baptist Parish, illustrating how these administrative divisions are projected across the water. Produced by the U.S. Geological Survey, the map provides a precise look at the township and range lines, such as t8s r10e and t8s r11e, as they intersect with the shoreline and the lake's expanse. For those studying the political geography of the region, it offers a clear view of how these maritime borders are officially recorded.
