2015 Map of Harney River

About this map

Everglades National Park covers this entire coastal landscape, where the freshwater sawgrass marsh gives way to a complex network of mangrove-lined tidal rivers. The sheet focuses on the convergence of the Broad River, Harney River, and Shark River as they flow west toward Ponce de Leon Bay on the Gulf of Mexico. This environment is characterized by its isolation and lack of permanent human structures, with the Wilderness Waterway providing the primary navigational route for those traversing these wetlands. The intricate hydrography shown here, including Gunboat Island and Tarpon Bay, illustrates the natural drainage patterns of the southern Florida peninsula. Historically significant watercourses like Graveyard Creek and the Wood River wind through the region, providing vital habitat and serving as the same routes used by early explorers and residents of the Florida frontier.
