Contained within the 1st Edition (1906) of the Atlas of Canada is a map that shows the delineation of drainage basins. The geographic extent of each drainage basin is delineated and the total area drained for each basin is provided in square miles. This includes the great oceanic drainage basin and the Hudson Bay basin. Only the Canadian drainage area is indicated on the map for basins that lie partly in the United States.

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).

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.

A drainage basin is the area that drains all precipitation into a river or stream system into a common outlet such as a lake or sea. There are two main river basins in Nunavut: the Thelon River flows into Hudson Bay and the Back River empties into the Arctic Ocean. Most of Nunavut’s area is not drained through large rivers; instead the water flows directly to the ocean through small rivers and streams.

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.

Contained within the 5th Edition (1978 to 1995) of the National Atlas of Canada is a map that shows ocean drainage areas with component river basins and diversion areas. There are two tables: one gives data on drainage basin areas, the other on major drainage diversions.

The “Major Basins of the AAFC Watersheds Project - 2013” dataset is a geospatial data layer containing polygon features representing the 23 major basins of the Agriculture and Agri-Food Canada (AAFC) Watersheds Project. The Project is subdivided by ‘incremental gross drainage areas’ associated to individual hydrometric gauging stations. The maximum area that could contribute runoff to each gauging station, less that of its upstream neighbour(s) is called an ‘incremental gross drainage area’. Conceptually, the major basins are collections of the “incremental gross drainage areas” associated with particular major river or lake reach (for example, reaches of the Saskatchewan or Athabasca River).

The “Major Drainage Systems of the AAFC Watersheds Project - 2013” dataset is a geospatial data layer containing polygon features representing the three (3) major drainage system basins of the Agriculture and Agri-Food Canada (AAFC) Watersheds Project. The Project area has been split according into which body of water it drains: the Arctic Ocean, Hudson Bay or Gulf of Mexico.
