Located between the comunes of
Ivrea and
Chiaverano, it is the largest of a group of five lakes of glacial origin known as
Laghi di Ivrea which also includes
Lake Pistono,
Lake Nero,
Lake Campagna, and
Lake San Michele. The lake, which was formerly known as
Lake San Giuseppe due to the presence of the nearby convent of the same name, is the only one that is fed by a spring. The lake's waterfront offers views on
Montalto Dora Castle and the
Aosta Valley. The historic
Società Canottieri Sirio country club, founded in 1887, is located on the lake's southern shore. == Nature protection ==
