The Saône originates on the southern part of the Lorraine Plateau and flows through the Saône-Rhöne intermontane depression; it is calm and flows along plains. The Saóne is fed primarily by rain, with the highest water levels from November through April. The level rises 3–4 m during flash floods; the mean flow rate near the mouth is approximately 400 cu m per sec. The Saóne is navigable for almost its entire length; the channel contains locks and is embanked in places. The river is connected by canals with the Moselle, Loire, Marne, Seine, and Rhine rivers. The city of Lyon is at the mouth.
