Lake George or Lake Welaka is a broad and shallow lake on the St. Johns River in the U.S. state of Florida. It is six miles (10 km) wide and eleven miles (18 km) long, with an average depth of 8 feet (2.5 m). The west side of the lake is encompassed in the Ocala National Forest. Three major spring groups flow into Lake George on the west side. Salt Springs enters the northwest side of the lake through the 4.3 mile (7 km) Salt Creek. Silver Glen Springs enters the lake about midway down on the west side, and multiple springs comprise Juniper Creek that flows into Lake George on the southwest side, with Juniper Springs at the headwater of the creek. The large island on the north side of the lake is Drayton Island.
