Lake Levico originated in relatively recent times owing to alluvial deposits from Rio Vignola and Rio Maggiore which dammed the portion of valley between mount Tenna and Canzana. These two rivers are the only tributaries of the lake, a part from some nameless brooks and the so called Marlezzo which marked the border between Levico and Pergine.
With a surface of 1.164 sq.km lake Levico is the second largest lake entirely located in the territory of Trentino. It is 950 m wide at its largest point, 2.840 m long, and 38 m deep. On the lakeside is a beach, a large public park as well as a few canebrakes.
The FEE Blue Flag (Foundation for Environmental Education, active in 41 countries across the world) is an important prize awarded to seaside and lakeside resorts for their commitment to sustainable tourism development.
Lake Levico is the first lake in the Trentino Alto Adige region to have been awarded (2013) the Blue Flag, as an acknowledgement for bathing water quality and services available at the beach, in the bathing establishments and in the resort of Levico Terme itself.
