2016 Map of Saint Charles Bay SE

About this map

San Jose Island and Matagorda Island dominate this coastal survey, where the barrier islands are separated by a shifting interface between the Gulf of Mexico and the inland waters. This 2016 topographic study captures the precise boundary between Aransas and Calhoun counties as it cuts through Mesquite Bay. The map provides a high-resolution view of the wetland margins and shoreline dynamics of Vinson Slough and the surrounding coastal marsh. Because much of this land is located within sensitive ecological zones or government-managed areas, this survey serves as a vital record of the terrain as it existed in the mid-2010s, tracing the landforms and tidal channels that define this portion of the Texas coast.
