1906 Canada Drainage Basins Map
Before satellites and digital elevation models, Canadian surveyors worked out where the water went by walking it. Drawn for the 1st Edition of the Atlas of Canada and published by Natural Resources Canada, this map sets out the delineation of the country’s basins and reports the total area drained by each in square miles.
The great oceanic drainage basin and the Hudson Bay basin are both mapped here. For rivers whose watersheds cross the border, only the Canadian drainage area is shown, a reflection of how the atlas was compiled. A companion table lists the lengths of Canada’s major rivers alongside their principal tributaries, making the sheet as much a reference document as a picture.
