2017 Map of Saint Catherines Sound

About this map

Saint Catherines Island and Ossabaw Island dominate this coastal landscape where the Medway River and Bear River converge at Saint Catherines Sound. The map reveals a complex network of tidal waterways and marshy hammocks, including Walburg Island and the expansive Bull Town Swamp. On the mainland, small residential enclaves like Colonels Island are accessed by local routes such as Lake Pamona Dr and Deloach Rd, while Yellow Bluff provides an elevated vantage point over the salt marshes of Ashley Creek. This environment is shaped by the Intracoastal Waterway, which cuts through the sound behind the Middle Ground shoals. The transition from the North Newport River to the open Atlantic Ocean illustrates the shifting coastal topography of the Georgia Sea Islands, where features like Medway Spit and Cedar Point define the barrier island boundaries.
