2024 Map of Santee Point

About this map

Winyah Bay dominates this coastal landscape where the waters of the Atlantic Ocean meet the complex estuary of the Santee River delta. The map details the shifting sands and intricate waterways of the South Carolina coast, from the broad expanse of the Winyah Bay Entrance to the smaller channels like Bird Bank Creek and Beach Creek. This 2024 survey documents the coastal morphology of major landmasses including North Island, South Island, and Cat Island, as well as the low-lying terrain of Pine Ridge. A notable point of historical interest is Quarantine on the eastern edge of South Island, a site reflecting the region's long history of maritime monitoring and disease control. The hydrologic network is dense, featuring engineered elements like the Rockfish Canal alongside natural tidal basins such as Wheeler Basin and Sand Creek Basin. Navigation hazards and seafloor features, including Mother Norton Shoal and the Cape San Roman Fishing Bank, illustrate the dynamic relationship between the shore and the sea.
