The waters of the Potomac and the Anacostia Rivers surround and define the nation's capital. For centuries, these rivers have been manipulated environments—transformed by native populations, settlers, politicians and real estate developers. With docks and wharves extending from the Anacostia River to Georgetown, the architect of the young capital, Pierre L'Enfant, planned to develop the waterfront into a prosperous inland seaport. Decades later, the Civil War took a devastating toll on the District's maritime economy with civilian port facilities pressed into military service and the failure of many riverfront plantations. Author John R. Wennersten explores this early history of Washington, D.C.'s waterfront even as he tackles its twentieth-century redevelopment and the challenges the rivers face today.
