Abraham Lake is an artificial lake on North Saskatchewan River in western Alberta, Canada. Abraham Lake has a surface area of 53.7 km² (20.7 sq mi) and a length of 32 km (20 mi). HistoryIt was built on the upper course of the North Saskatchewan River, in the foothills of the Canadian Rockies. It lines David Thompson Highway between Saskatchewan River Crossing and Nordegg. Abraham Lake was created in 1972, with the construction of the Bighorn Dam. It was named for Silas Abraham, an inhabitant of the Saskatchewan River valley in the nineteenth century.1 Although man-made, the lake has the blue color of other glacial lakes in the Rocky Mountains, which is caused by rock flour as in other glacial lakes. The Cline River Heliport is located on the western shore of the lake. See alsoReferences
