In the Adamello Brenta Nature Park there are 48 lakes. Some lie in open and bright basins at high altitudes, others reflect the thick surrounding forests in their waters. The distribution of lakes in the two sectors of the Park differs greatly.
The lakes of the Adamello-Presanella
In the Adamello-Presanella area there are 44 lakes. In fact, the hardness and the waterproofness of the rocks favor the stagnation of water. Lake Vedretta
The lakes of the Brenta Dolomites
In the Brenta area there are only 4 lakes. In fact, the superficial waters tend to disappear underneath the ground, as a consequence of the permeability of calcareous and dolomitic formations. The solitary lakes of Brenta are, besides Lake Tovel, lake Spinale on the homonymous mount, lake Valàgola and the tiny lake Asbelz at the head of Val di Jon.
Almost the entirety of lakes in the Adamello Brenta Nature Park have glacial origins, in other words they lie in basins dug by glaciers. The majority possess the typical structure of “cirque” lakes, covering small circular depressions in the rock, modelled by modest tongues of ice. Sometimes they are blocked by moraines, that are responsible for the raising of the lake waters.The only exception to the glacial origin is constituted by Lake Tovel, the largest of the Park, originated from the valley block caused by a great landslide. Groups of lakes In the Park, the lakes are often located close to each other, forming groups that occupy basins eroded by small glaciers and previously constituting a major single body. Magnificent groups of lakes are those of Mandrone, Germenega and Garzonè on the Adamello; Cornisello, Serodoli and Malghette on the Presanella. Lago di Cornisello.
Following, some of the lakes of the Park are presented. The descriptions are inspired by studies and research relating to the Project “Valagola SEFIRA” (MuSe), to the guide “Guida dei laghi del Parco” (Cantonati et al.) and to the book “I Trecento Laghi del Trentino” (Gino Tomasi):
