During the postbellum period, the U.S. Army Corps of Engineers began the regular dredging of Georgia's inland waterway. Certain sections of the waterway, primarily those behind the barrier islands where the tides meet and cause shoaling (or dividings), require periodic dredging. Such examples are the Florida Passage–Bear River segment between Ossabaw Island and the Bryan County mainland, North Newport River west of St. Catherines Island, Buttermilk Sound northwest of St. Simons Island, and Jekyll Creek and the Cumberland Dividings. The inland waterway on the Georgia coast also passes through two areas known as "narrows," with both areas exhibiting a tendency to shoal. Narrows along the inside route have posed problems for mariners since colonial times.
