Thanks to its 2.34 sq. Km surface and 163.000 cu.m volume, it is the biggest of all the natural Bergamask basin; the flow of its effluent, river Cherio, is 1,4 cu.m per second, while its average depth is 5,1 m and the maximum is 9,4 m.

The lake represents an important touristic resource which, although the present conditions of the lasting non-swimming of its waters, attracts a lot of visitors especially during the summer months. As the engine traffic is forbidden, in the last years the lake has been knowing a spread of boating, canoeing and fishing, thanks to an exploitation and promotion campaign.

Since the 60's this post-glacial lake has been showing a marked eutrophication process, due particularly to the anthropic impact, to which they have been looked for remedies, through a series of interventions fostered by the Mountain Community.
