2019 Map of Mission Bay

About this map

Mission River winds through the coastal lowlands of Refugio County, depositing sediment into the expansive Mission Lake and Mission Bay complex. This hydrological network defines the local geography, where freshwater systems like Melon Creek and Mullens Bayou meet the brackish waters of Copano Bay. The map reveals a landscape managed for transit and drainage, characterized by rural routes such as Mission River Rd and Cemetery Rd that navigate the marshy terrain. Small landmarks like Hynes Springs and the named area of Rancho Grande offer specific points of interest for those tracing the historical footprint of ranching and water access in this coastal Texas region during the late twenty-first century.
