2025 Map of Mesquite Bay

About this map

Matagorda Island and San Jose Island anchor this coastal landscape where the barrier islands meet the expansive Texas bay system. The modern Intracoastal Waterway cuts through the center of the sheet, providing a primary transit corridor across the boundary of Aransas and Calhoun Counties. The map reveals a complex aquatic environment defined by the convergence of Mesquite Bay, San Antonio Bay, and Ayres Bay, separated by natural features like the Second Chain of Islands and Ayres Reef. On the mainland side, the Black Jack Peninsula extends into the waters near Long Lake and Mustang Slough, illustrating the intricate shoreline and drainage patterns typical of the Texas Gulf Coast. This contemporary survey captures the delicate balance between open bay waters and the protected inlets of Bray Cove and Big Brundrett Lake.
