Lake Viverone (, ) is the third largest lake in Piedmont, Italy. It is located between the northeasternmost part of the Canavese area (eastern Eporediese) and the southernmost part of the Biellese area; it takes its name from the municipality of the same name to which it mostly belongs.
Named after the town of Viverone, lies at 230 m AMSL between the districts of Biella, Vercelli and Ivrea in the area of morainic hills known as Serra. It has an area of about 6 km<sup>2</sup> and a maximum depth of 50 m, and a perimeter of about 13.1 km. The lake is 3,470 m long and 2,550 m wide. The southern and western parts of the lake are rich in vegetation while the north part is built-up and includes hotels, camping sites and beaches.
Ducks, mallard, coots, grebes and gulls form the major part of the fauna; angling is a popular activity with catches including common whitefish, perch, tench, pike and catfish.
Viverone is a centre for day trips and the lakeside communities of Lido, Masseria, Comuna and Anzasco have recently been connected by a boat service.
The lake is also an important archaeological site: villages made up of stilt houses were present here in the Bronze Age (1300âÂÂ900 BCE).
