About this map

Galveston Island stretches across the lower portion of this 2010 survey, showcasing the established resort communities of Sea Isle, Terramar Beach, and Bay Harbor. These coastal developments are defined by a complex network of man-made canals and docks, anchored by the Marina at Sea Isle. The map captures the vital role of the Intracoastal Waterway as it cuts through West Bay, separating the island from the mainland marshes and tidal inlets of the Texas coast.

To the north, the landscape transitions into a maze of bayous and points, including Halls Bayou and Chocolate Bay. Natural landmarks like Rattlesnake Mound and Alligator Point provide topographical contrast to the low-lying wetlands. The cartography reveals the intricate hydrography of the region, from the wide expanse of Carancahua Lake to the small, scattered features like Snake Island and Bird Islands that dot the bay waters.
