The Crown Jewel of Southeastern Rivers In 1974 the Chattooga River became the first river East of the Mississippi to be included in the National Wild and Scenic River System. It was included because it was a clean, free-flowing mountain stream located in a relatively undeveloped mountain environment. Forming part of the Georgia-South Carolina Border, the Chattooga is the only free-flowing portion of the Savannah River System. This book gives a comprehensive overview of the river including the topography, physiography and geology, weather and climate, human history, plant life, wildlife, and recreation opportunities.
