List of lakes of Alberta

Most of Alberta's lakes were formed during the last glaciation, about 12,000 years ago.

Distribution of the lakes throughout the province of Alberta is irregular, with many water bodies in the wet boreal plains in the north, and very few in the semi-arid Palliser's Triangle in the southeast.

[1] Most of Alberta's waters are drained in a general north or northeastern direction, with six major rivers forming four major watersheds collecting the water and removing it from the province:[2] As with other basins on the planet, the topographical highlights in the drainage divides between these basins can be difficult to discern.

For example, there is little elevation change in the short 4 kilometres (2.5 mi) of land between Lac la Biche and Beaver Lake, yet the former is in a watershed that drains north into the Arctic Ocean, while the latter is in a watershed that drains east into Hudson Bay.

This section provides a list of lakes of Alberta with an area larger than 100 km2 (39 sq mi).
