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.
