Lake Champlain level. 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 -long Richelieu River into the St. Lawrence River at Sorel-Tracy, Quebec, northeast and downstream of Montreal, Quebec. It also receives the waters from the -long Lake George, so its basin collects waters from the northwestern slopes of the Green Mountains and the northernmost eastern peaks of the Adirondack Mountains. Lake Champlain drains nearly half of Vermont, and approximately 250,000 people get their drinking water from the lake. The lake is fed in Vermont by
Lake Champlain Seaway advancing beyond the early planning stages. The Great Depression cut the project's planning budget, while World War II and completion of the St. Lawrence Seaway delayed matters. The growth of road and air transportation reduced the need for a canal, but the project was still under serious consideration as late as 1962. As proposed, ships would have used a dredged channel in the Hudson River, transferred to an upgraded Champlain Canal, navigated Lake Champlain, traversed an upgraded Chambly Canal and St Ours Canal, and traveled a dredged route up the Richelieu River to Montreal. Today, the seaway's planned route is
