2010 Map of Mission Bay

About this map

Mission Bay and the surrounding coastal marshlands of Refugio County define this 2010 coastal landscape. The hydrology of the region is centered on the confluence of the Mission River and Melon Creek as they drain into Mission Lake before reaching the larger expanse of Copano Bay. This complex network of bayous and wetlands, including Mullens Bayou, illustrates the delicate coastal interface of the Texas Gulf Coast. The map reveals a land divided between its natural aquatic features and a rural road network, with routes like Rancho Grande and Mision River Rd providing access to the riverbanks. Features such as Copano Reef underscore the importance of the bay's natural underwater structures, while local names like Gin Rd hint at the agricultural heritage that once dominated the upland areas surrounding these tidal waters.
