Contained within the 3rd Edition (1957) of the Atlas of Canada is a map that shows drainage basins and river flow. The delimited drainage basins cover all Canadian land and fresh water areas. The areas of many drainage basins are written on the map. These areas do not include diversions (thus, the Albany does not include the area of its basin diverted to the St. Lawrence system).

This map shows the five ocean drainage areas in Canada, the major river basins, the internal drainage areas and the diverted drainage areas. A drainage basin, sometimes called a watershed, is an area where all surface water shares the same drainage outlet. Surface water consists of the tiny trickles of water flowing on the surface of the earth that develop into larger streams and eventually combine to form a river. The boundary of a watershed is called a drainage divide.

A drainage basin is an area that drains all precipitation received as a runoff or base flow (groundwater sources) into a particular river or set of rivers. Canada’s major drainage regions are the Atlantic Ocean, Hudson Bay, Arctic Ocean, Pacific Ocean and Gulf of Mexico. Rivers are organized into networks, each with its own recharge area upstream, and drainage channel and mouth downstream. Networks are ordered from ocean to main river to secondary rivers to streams which correspond to ocean basins, river basins, sub-basins, sub-sub-basins, and so forth.
