Lago Bianco

Lago Bianco is a reservoir at the Bernina pass in the Swiss canton of Graubünden. It has an elevation of 2,234 m, a length of 2.85 km, a surface area of 1.50 km2 and a maximum depth of 53 m. Once the site of two smaller lakes, the current reservoir was formed by the constructions of two dams at its southern and northern ends. The current lake drains to the south, as did both its precursor lakes, with its water eventually reaching the Mediterranean via the rivers Poschiavino, Adda and Po.
