The Lago di Robièi is an equalization basin of the Maggia power plants in the north of the canton of Ticino . It has a usable volume of 6.5 million with a total volume of 6.7 million cubic meters and is located at 1940 m above sea level. M. . The nearby Lago del Zött is connected to the Lago di Robièi by a tunnel, so that the two lakes are connected to one another according to the principle of communicating vessels .
The reservoir absorbs the underwater from the Altstafel headquarters on the Valais side, which is fed into the lake through a 13 km long gravity tunnel before it is fed to the Bavona headquarters. The Robièi headquarters can also dispense processed water from Lago dei Cavagnöö , Lago Sfundau and Lago del Narèt into the lake or pump water from Lago di Robièi into the aforementioned lakes. The lake also stores the water from the Basòdino glacier , which enters the lake via Lago del Zött.
The Lago di Robièi lies at the far end of the Bavona valley , which belongs to the municipality of Cevio . From the village of Bignasco in the Maggia valley , one reaches San Carlo , the farthest hamlet in the valley, via a well-developed side street , where the valley station of the San Carlo – Robièi cable car is located about a hundred meters above the settlement , which leads to the reservoir 900 m higher. The heavy-duty cable car was built in 1972 for power plant construction and is also used for tourism during the summer months. The dam can be visited.
