2024 Map of Bay Keys

About this map

Great White Heron National Wildlife Refuge and Key West National Wildlife Refuge converge in this aquatic landscape within the Gulf of Mexico. The map highlights the sparse, low-lying island clusters of the Bay Keys, including West Harbor Key and Cayo Agua, which are separated by a network of tidal passages. Navigational arteries such as the Intracoastal Waterway, Bluefish Channel, East Harbor Key Channel, and Calda Channel define the movement of vessels through these protected shallow waters. This contemporary survey by the U.S. Geological Survey illustrates the intersection of federal conservation boundaries in the lower Florida Keys, where the environment remains largely undeveloped for maritime and wildlife preservation.
