Watersheds

Watersheds 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. 2022-03-14 Natural Resources Canada geoinfo@nrcan.gc.ca Form DescriptorsNature and EnvironmentScience and Technologyenvironmentmapwatersheds Download the English JP2 File through HTTPJP2 https://ftp.geogratis.gc.ca/pub/nrcan_rncan/raster/atlas_6_ed/eng/6415_watersheds.jp2 Download the English ZIP (PDF,JPG) file through HTTPZIP https://ftp.geogratis.gc.ca/pub/nrcan_rncan/raster/atlas_6_ed/eng/6415_watersheds.zip Download the French JP2 File through HTTPother https://ftp.geogratis.gc.ca/pub/nrcan_rncan/raster/atlas_6_ed/fra/6415_bassins_versants.jp2 Download the French ZIP (PDF, JPG) File through HTTPZIP https://ftp.geogratis.gc.ca/pub/nrcan_rncan/raster/atlas_6_ed/fra/6415_bassins_versants.zip
