Lesser Slave Lake is located in central Alberta, Canada, northwest of Edmonton. It is the second largest lake entirely within Alberta boundaries (and the largest easily accessible by vehicle), covering 1,160 km2 (450 sq mi) and measuring over 100 km (62 mi) long and 15 km (9.3 mi) at its widest point. Lesser Slave Lake averages 11.4 m (37 ft) in depth and is 20.5 m (67 ft) at its deepest. It drains eastwards into the Athabasca River by way of the Lesser Slave River.
The town of Slave Lake is located at the eastern tip of the lake, around the outflow of Lesser Slave River. According to the town's website, the name Slave Lake originated with "an aboriginal nation derogatorily named 'Slavee' by several tribes of the invading Cree nation."
Conservation and development
Due to its location on a major fly-way for migrating birds, Lesser Slave Lake is popular with birders. The nearby Lesser Slave Lake Provincial Park has lakeside camping facilities located along sand beaches, with some rocky beaches as well. Fishing is popular and legal. The entire north shore of the lake is protected, other reserves being Hilliard's Bay Provincial Park, Lesser Slave Lake Wildland and Grouard Trail Park Reserve.
A number of Indian reserves are established at the shores of the lake:
- Kapawe'no First Nations Lands 150, 230 and 231 of the Kapawe'no First Nation,
- Sucker Creek 150a of the Sucker Creek Cree First Nation
- Drift Pile River 150 of the Driftpile First Nation
- Swan River 150e of the Swan River First Nation
- Sawridge 150g and h Sawridge Band
