About this map

Aransas Bay and the Gulf of Mexico dominate this coastal survey, where a complex network of barrier islands and oyster reefs defines the maritime landscape. The Intracoastal Waterway cuts a straight path through the center of the bay, serving as a vital artery for navigation amidst the shifting shoals of Mack Reef, Shell Reef, and Long Reef. To the north, the Blackjack Peninsula terminates at Blackjack Point, marking the entrance to Carlos Bay. This environment is characterized by isolated landforms like Deadman Island and Big Island, along with numerous small hazards such as Thompsons Towheads and Pelican Reef. The intricate hydrography, including Vinson Slough and Spalding Bight, highlights the ever-changing nature of the Texas shoreline and its tidal marshlands.
