List of longest rivers of Canada
Nine rivers in this list cross international boundaries or form them. Four—the Yukon, Columbia, Porcupine, and Kootenay—begin in Canada and flow into the United States. Five—the Milk, Pend d'Oreille, Saint Lawrence, Red, and Saint John—begin in the United States and flow into Canada. Of these, the Milk and the Kootenay cross the international border twice, the Milk leaving and then re-entering the United States, the Kootenay leaving and then re-entering Canada. The drainage basins of these nine rivers extend into both countries; in addition, the drainage basins of six others—the Fraser, Assiniboine, South Saskatchewan, Saskatchewan, Nelson, and Winnipeg—extend into the United States even though their main stems flow entirely within Canada.
Indian Lake Chain, Ontario
The Indian Lake Chain is a tourism designation given to a series of interconnected lakes located northwest of the community of Vermilion Bay in Kenora District, Ontario, Canada. The designation takes its name from Indian Lake that is part of the series. According to maps published by resorts located on the lakes, the Indian Lake Chain consists of ten lakes: Little Boulder Lake, Boulder Lake, Cobble Lake, Bladder Lake, Big Moose Lake, Little Moose Lake, Whitney Lake, Edward Lake, Indian Lake and Forrest Lake. However, the Atlas of Canada shows only seven lakes, as Little Boulder, Boulder, Cobble and Bladder Lakes are all simply designated "Cobble Lake". The surface elevation of the lakes is approximately , and the water level is maintained by the Forest Lake Dam. (Forest Lake is spelled with two "R"s on local maps but only one at the Atlas of Canada).
