Lago di Fontana Bianca
It is held back not by one dam, but by two.

Lake Fontana Bianca, known in German as Weißbrunnsee, is an artificial reservoir at an altitude of 1,872 metres, in the municipality of Ultimo. It is the starting point for the ascents to Cima Sternai and Gioveretto.
It is held back not by one dam but by two, relatively small gravity dams built of earth and rock between 1957 and 1959. The hydroelectric power station connected to the lake exploits a drop of 731 metres and has two Pelton turbines, with a maximum output of 44 megawatts and an annual production of 91 gigawatt hours. In 1963 the power station was refurbished so that it could also use the water coming from Lake Quaira.
