Bighorn Dam

Bighorn Dam is a dam located in Clearwater County in west-central Alberta, Canada. It was built by TransAlta Corporation in 1972, and lead to the creation of Lake Abraham, Alberta's largest man-made lake.

The plant is one of two TransAlta hydroelectric plants on the North Saskatchewan River System in Alberta. The Bighorn Plant generates more electricity each year than any of TransAlta's other hydro plants, enough to supply the equivalent of 58,300 Alberta households. The Bighorn embankment dam was built in 1972 in the mountain gap at Windy Point, in the Front Ranges of the Canadian Rockies, west of the confluence of the North Saskatchewan River and the Bighorn River.
