Mayo Lake is about 100 square kilometers large lake in the Yukon Territory in Canada , 35 km east-northeast of the settlement Mayo .
A drainage control structure was completed at the lake in 1952, which raised the lake level by 5 m. Since then, the lake's water level has fluctuated between 663.25 m (low supply level) and 665.84 m (full supply level). During the period with lower natural runoff, the reservoir serves as a water reservoir for two hydropower plants located downstream on the Mayo River , Mayo A (built in 1951, 2 × 2.5 MW, 36 m head) and Mayo B (built in 2011, 2 × 5 MW, 64 m drop height). The power plants supply the nearby Keno Hill mine as well as the towns of Elsa , Keno City and Mayo with electricity.
Mayo Lake has a Y-shape with the drain at the western end of the lake. The two main tributaries, Nelson Creek and Roop Creek , flow into the two arms of the lake, Nelson Arm (the southern one) and Roop Arm (the northern one) . The lake is usually covered with ice from late November / early December to early / mid June. There are efforts to lower the height of the low supply level by one meter. This would increase the usable storage volume of the reservoir.
