Note: The following is part of a series of columns exploring use of rivers in the early history of Georgia and Bulloch County. The "Executive Documents" (1888) reported that most of the improvements made on the Altamaha up until this time had been done at the "Doboy Bar," which lay at the "mouth of Darien River ... the northerly main branch of the delta portion of the Altamaha." D.C. Kingman's "Survey of the Altamaha" (1911) revealed that "there is on hand (now) for clearing of the river ... a snag boat, a 10-inch pumping dredge, with pipe line and pontoons, a steam hoister, a pile driver, and sundry small boats and barges."
