2010 Map of Saint Charles Bay SE

About this map

Matagorda Island and San Jose Island dominate this coastal landscape, separated by the narrow passage of Cedar Bayou. This 2010 survey highlights the complex estuarine environment where the Gulf of Mexico meets the Texas barrier island system. To the north, Mesquite Bay is defined by a maze of wetlands and tidal channels including Vinson Slough. Human activity is sparse on these protected shores, centered primarily around the Wynne Ranch and the Aransas National Wildlife Refuge Airport on the mainland's edge. The map provides a precise view of the shifting shoreline and the delicate hydrography of the Aransas County coast before modern climate and storm impacts further altered these barrier features.
