Each of these watersheds can be broken into hundreds, even thousands of sub-watersheds for creeks, lakes
and wetlands. The river basins can be grouped by the ocean they drain into. The North and South Saskatchewan
Drainage Basins meet in Saskatchewan to create the Saskatchewan River Drainage Basin, which eventually flows
into Hudson's Bay.
