This is a list of lakes of Alberta, Canada. Most of Alberta's lakes were formed during the last glaciation, about 12,000 years ago. There are many different types of lakes in Alberta, from glacial lakes in the Canadian Rockies to small shallow lakes in the prairies, brown water lakes in the northern boreal forest and muskeg, kettle holes and large lakes with sandy beaches and clear water in the central plains. 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.

River basins

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: 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 km 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.

Largest lakes

Lake Athabasca is the largest lake in both Alberta and Saskatchewan. This 7850 km2 lake has 2295 km2 of its surface area in Alberta and 5555 km2 in Saskatchewan. The largest lake completely within Alberta is Lake Claire, at 1436 km2. Lake Claire is just west of Lake Athabasca, with both located in the remote Peace-Athabasca Delta. This section provides a list of lakes of Alberta with an area larger than 100 km2.

List of lakes

This section provides a list of numerous lakes of Alberta, including the "large" ones shown in the previous section. Note that the lakes are listed alphabetically by their main name, dropping any leading "lake", "lac", "lac la", "upper/lower", "north/south". For example, Lac la Nonne (the nun lake) is entered under "N". If desired, using the table sort function will give the list sorted by the leading word.
