2025 Map of Long Island

About this map

Espiritu Santo Bay dominates this coastal landscape, where a complex network of barrier islands and shallow lagoons forms a dynamic interface with the Gulf of America. The modern Intracoastal Waterway cuts through these waters, providing a protected passage north of Long Island and Shoalwater Bay. This maritime environment is defined by its shifting sands and tidal features, from the expansive Matagorda Island shoreline to the submerged hazards of Josephine Reef. The map reveals the intricate hydrography of the Texas coast, including the First Chain of Islands and isolated bodies like South Pass Lake and Long Lake. While largely defined by water and wetlands, the presence of Lane Rd at the northern edge suggests the very beginning of landward infrastructure reaching toward these tidal flats and marshes.
