Westlock County is a municipal district in central Alberta, Canada that is north of Edmonton. The county was formerly known as the Municipal District of Westlock No. 92, and was created in 1943 from the merger of five smaller municipal districts.
The county lies on the boundary of two of Canada's largest drainage basins. The northern and western sectors of the county are drained by the Pembina River which flows north to meet the Athabasca River, which drains into the Arctic Ocean via the Mackenzie River. The southern and eastern sections drain into the Sturgeon River which joins the North Saskatchewan and eventually empties via the Nelson River into Hudson Bay.
A 1986 federal map shows the area as being the north-western edge of the Eastern Alberta Plains. Specifically, the county includes parts of the Edmonton Plain (and its subdivision Westlock Plain), as well as the Tawatinaw Plain, and is bounded on the northwest by the Athabasca Valley.[1] The county also lies within the apen parkland: a transitional biome between the boreal forest of Canada to the north and the prairie to the south.
