| Abstract | 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. Canadas 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. The largest set of
lakes, the Great Lakes, straddle the Canada-US boundary and contain 18% of the worlds fresh water in lakes. Most Canadian rivers have developed since the last ice age. Almost 75% of the Canadian landmass contains water that drains northward into
either the Arctic Ocean or into Hudson and James bays. |
| Summary | (Plain Language Summary, not published)
The map was originally published online in the Atlas of Canada, 6th Edition as an interactive digital map derived from a shapefile and mapped online
using MapServer, a platform for publishing spatial data to the web. In order to preserve the geographical content of this Edition during its publication from 1999 to 2009 all the maps have been converted from their online interactive form to a raster
and made available in PDF and JPEG. |
