2025 Map of Saint Charles Bay SE

USGS Topo · Published 2025

About this map

San Jose Island and Matagorda Island define this coastal stretch along the Texas barrier island chain. This 2025 survey illustrates the dynamic boundary where the Gulf of America meets the complex network of salt marshes and tidal channels. The division between Aransas and Calhoun Counties runs through these waters, bisecting the passage near Mesquite Bay and the winding Vinson Slough. The landscape is characterized by its absence of road infrastructure or permanent settlements, reflecting the protected and shifting nature of the barrier island environment as it appeared in the mid-2020s. For those studying the hydrology and geography of the Gulf Coast, this map provides precise topography of the inlet systems and wetlands that separate the mainland from the open sea.
