Note: The following is part of a series of columns exploring the use of rivers in the early history of Georgia and Bulloch County. Despite all the efforts, the Savannah River was never conquered. Executive Documents (1886) included the report of U.S. Army Corps of Engineers Capt. O.M. Carter, in which he wrote that "during the low-water season there are ... low-water depths of not more than 3 feet ... (and) the chief obstruction to navigation consists of sand and gravel bars, overhanging trees, snags, and sunken logs."
