The Lesser Slave Watershed


Lesser Slave Lake (LSL) is the third largest lake in the province, a popular tourist destination and a recognized biologically significant area for bird life. The lake is a source of water for agriculture, forestry, and recreation/tourism, domestic and municipal uses. It supports major sport, commercial and domestic fisheries.

There are beaches, campsites, recreation areas, and provincial parks all around it's shore. Communities located on the shores of the lake include the Town of Slave Lake, the village of Kinuso, the hamlets of Grouard, Joussard, Faust and Canyon Creek and the First Nation communities of Kapawe’no, Sucker Creek, Driftpile, Swan River, and Sawridge.

Lesser Slave Lake has a surface area of approximately 1,150 km2

The lake is fed by various tributary rivers entering at Buffalo Bay. The three largest tributaries are the Driftpile, Swan and Assineau rivers. Many small creeks and intermittent streams also flow into the lake. Outflow is on the east end of the lake via the Lesser Slave River, which joins the Athabasca River about 75 km downstream.

Over the years there have been many technical studies about our watershed, you can find them here.
