Alberta's River Basins



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.

You can view the name of a river basin by clicking the map and moving your mouse over it to highlight an area.

Alberta has six major river basins:

  • Peace/Slave
  • Athabasca
  • Hay
  • North Saskatchewan
  • Beaver
  • Milk River

The South Saskatchewan River Drainage Basin is formed by four sub-basins.

  • Oldman,
  • Red Deer
  • South Saskatchewan
  • Bow River sub-basins
