| Abstract | (unpublished)
The map shows the six major drainage areas in Canada, the major diversions in 1975 and the flow (in cubic metres per second) of rivers whose mean annual flow at the outlet of
their river basin exceeds 400 cubic metres per second. The Mackenzie and the St. Lawrence rivers have the two largest annual flows. The world's largest river, the Amazon, has an average discharge of 212,000 cubic metres per second; more than
one-sixth of the world's total river discharge. The Congo, second largest, has an average discharge of 39,600 cubic metres per second, less than one-fifth the flow of the Amazon. The largest river in North America, the Mississippi, has an average
discharge of 17,300 cubic metres per second. Canada's largest, the St. Lawrence, discharges 10,100 cubic metres per second, at Nicolet; her second largest, the Mackenzie, flows into the Arctic Ocean with a mean annual discharge of 9,910 cubic metres
per second. Discharges for the map were estimated at the river mouth or where the river crossed the |
