Lake Champlain is in the Lake Champlain Valley between the Green Mountains of Vermont and the Adirondack Mountains of New York, drained northward by the Richelieu River into the St. Lawrence River at Sorel-Tracy, Quebec, northeast and downstream of Montreal. The Champlain basin collects waters from the northwestern slopes of the Green Mountains and the eastern portion of the Adirondack Mountains, reaching as far south as the Lake George in New York.
