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.
