About this map

Matagorda Island forms the backbone of this coastal survey, where the delicate barrier ecosystem separates the Gulf of America from the protected waters of San Antonio Bay. The landscape is dominated by tidal marshes and interior brackish waters, including Panther Point Lake and the nearby Swan Lake. Navigation and ecological studies of this Calhoun County shoreline find essential detail here, specifically along the extending landforms of Panther Point and Cedar Point.

Submerged features like Panther Reef illustrate the shifting sands and shallows that characterize this stretch of the Texas coast. The map also documents isolated water bodies on the island's interior, such as Cedar Lake and Twin Lakes, which provide a detailed look at the island's morphology as it stood in the mid-2020s. This is a purely maritime and wilderness environment, devoid of road networks or human settlements.
