Wabamun Lake, Recreational lake with provincial park in Alberta, Canada

Wabamun Lake is a large freshwater lake in Alberta surrounded by forest and grassland, with a sloping shoreline offering multiple access points. The provincial park features campsites and day-use areas distributed along different sections of the waterfront.

Early 1900s railway development connected the lake to distant markets, allowing local fisheries to grow and ship their catches far beyond the region. This transportation link brought economic growth and settlement to the surrounding area.

The name comes from the Cree word wâpamon, "mirror", and the lake is called Wihnemne in Stoney. Early surveys recorded it as White Whale Lake for its whitefish. Seba Beach keeps the vacant whitefish cannery building, and the Paul First Nation's Wabamun No. 133A reserve lies on the eastern shore.

The lake lies 65 km west of Edmonton, with communities such as Wabamun, Seba Beach and Kapasiwin along its shores. The most popular swimming spots are the artificial beach at the provincial park in Moonlight Bay and the natural beach at Seba Beach; elsewhere emergent vegetation restricts access to the water. Ice covers the lake from December to April, and surface water reaches about 25.6 °C in August.

The lake was surveyed as "White Whale Lake" for its large whitefish, and from Seba Beach a cannery shipped fish by rail as far as New York City. The vacant cannery building still stands in the village. In winter, ice was cut from the lake to supply refrigeration cars on the railway.
