A watershed is an area that drains all precipitation received as a runoff or base flow (groundwater sources) into a particular river or set of rivers. The easiest way to describe the network of rivers and lakes on a small-scale map is to show the watersheds. In Canada, there is a detailed hierarchy of watersheds, ranging from the largest (drainage into oceans and their equivalents), down to the smallest ramification. Canada’s ocean watersheds are the Atlantic Ocean, Hudson Bay, Arctic Ocean, Pacific Ocean and Gulf of Mexico.

Contained within the Atlas of Canada 8.5x11 series maps is a map which was created as a joint effort by The Atlas of Canada, The National Institute of Statistics, Geography and Informatics, Mexico and the National Atlas of the United States under the sponsorship of the commission for environmental cooperation. The map shows the major North American drainage basins, or wateresheds, which drain into the Atlantic Ocean, Hudson Bay, the Arctic Ocean, the Pacific Ocean, the gulf of Mexico and teh Caribbean Sea. Each watershed is shown in its own colour, with subdivisions shown in tonal variations. Areas of internal drainage, which lack outlets to the sea, are shown in grey.

This map shows the five major ocean drainage areas in Canada: Hudson Bay, Arctic Ocean, Atlantic Ocean, Pacific Ocean and Gulf of Mexico. An inset map shows the major dams with reservoir capacity larger than 1 billion cubic metres. Six of the 10 largest hydro-electric generating stations by capacity are located in the province of Quebec; whereas, the largest, Churchill Falls is in Newfoundland and Labrador. The other 3 are located in British Columbia.

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 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. A lake can be defined as any inland body of water, usually fresh water, larger than a pool or pond. Canada is covered by as many as two million lakes.

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.

The physical components of a watershed are rivers, lakes, ponds and reservoirs, groundwater aquifers, snowpacks, glaciers, ice fields, wetlands and precipitation. This map shows the different hydrological components of a watershed, some physical components that affect watersheds and some components that describe watersheds. The original map consisted of several optional layers to show the characteristics of the physical environment that effected or affected watersheds. Only layers from the original map that could be viewed simultaneously without loss of information are mapped.

Apart from a source of drinking water, the water resources in watersheds supply water for irrigation and the production of hydroelectricity, and are a primary mode of transportation. Major water consumers are municipalities, agriculture, mining, manufacturing and thermal power generation. The original map consisted of several optional layers to show the impact of human activity on watersheds and the utilization of watersheds for economic, social or cultural purposes. Only layers from the original map that could be viewed simultaneously without loss of information are mapped.

Swimming is one of the uses of freshwater. The map shows the amount of participation as mapped by major watershed. Not surprisingly, the highest absolute numbers occur in southern Canada.
