Lake George drains into Lake Champlain to its north through a short stream (La Chute river) with many falls and rapids, dropping about 230 feet (70 meters) in its 3½-mile (6 km) course. Ultimately the water flows into the St. Lawrence River and then into the Atlantic Ocean.
The original name in Iroquois was said to be Andiatarocte, the lake shut in and was named by the French Lac du Saint-Sacrement, (Lake of the Holy Sacrament).
The Village of Lake George is located at the south end of Lake George and the unincorporated village of Ticonderoga is at the northern end. The area is a well-known resort center and summer colony.
