Abraham Lake is a reservoir on the North Saskatchewan River in Clearwater County in the province of Alberta , Canada.
Abraham Lake was created by damming the North Saskatchewan River at the Bighorn Dam, which was built by TransAlta in 1972. The dam is located at Windy Point on the western shore of the lake and is 90 meters high.
Abraham Lake is known for a natural phenomenon that can be observed there in winter. Bacteria at the bottom of the lake emit methane all year round, which rises within the water column. In winter, the gas reaches colder layers of water where it freezes into milky bubbles.
Because of these events, Abraham Lake has become a popular destination for photographers.
