Its drainage basin covers nearly all of Idaho, large portions of British Columbia, Oregon, and Washington, ultimately all of Montana west of the Continental Divide, and small portions of Wyoming, Utah, and Nevada; the total area is similar to the size of France. Roughly of the river's length and 85 percent of its drainage basin are in the US. The Columbia is the twelfth-longest river and has the sixth-largest drainage basin in the United States. In Canada, where the Columbia flows for and drains , the river ranks 23rd in length, and the Canadian part of its basin ranks 13th in size among Canadian basins.

Lakeland Provincial Park and Recreation Area
The Lakeland area straddles two drainage basins, and is thus drained by two major river systems, the Athabasca and the Beaver-Churchill. The Athabasca River drainage basin is the second largest drainage basin in Alberta. It drains 5 of the major lakes in the north-west section of the Lakeland area, including Blackett, Dabbs, Kinnaird, and McGuffin lakes, which all flow into Jackson Lake. Jackson Lake is drained by Gull Creek, which ultimately flows into the Piche River, which in turn joins the Owl River, then Lac La Biche, the La Biche River, and ultimately, into the Athabasca River and on to the Arctic Ocean.
