Palü Lake (Italian: Lago Palü, Romansh: Lagh da Palü, German Palüsee) is a lake below Piz Palü in the Swiss canton of Graubünden. It has an elevation of 1,923 m (6,309 ft) and a surface area of 5.2 ha (13 acres). Water from Palü Glacier feeds into the lake.
In 1926, a dam was built enabling use of the lake as a reservoir. The nearby Palü hydro-electric power station has an installed capacity of 10 MW and is fed by a pressurised pipe-line from Lago Bianco. The outfall from this plant, along with water from Lago Palü, feeds an underground pipeline to the Cavaglia power station at Cavaglia. The 800-metre (2,600 ft) tunnel connecting the two plants also accommodates a funicular railway that is open to the public during tours of the plants.
