Detailed map

The Lago Ritóm is a reservoir in Pioratal ( Val Piora ), a side of Leventina in the Swiss town Quinto in Ticino . To the north is the small Lago di Tom .

The lake is of glacial origin and is from 1917 to 1920 to the reservoir for the Ritom power plant of the SBB been extended. The 170 meter long heavyweight wall was raised in 1950 to a height of 23 meters and 309 meters in length. However, due to the porous subsurface in the upper area, this height cannot be fully used.

The lake is accessible via mountain hiking trails, a driveway or the very steep Ritom funicular (max. 87.8%). There is also accommodation near the dam.

In the original natural lake, the rare phenomenon of geogenic meromixis could be observed. There are different layers of water that remain stably separated. So there is no seasonal mixing of the different water layers. The neighboring Lago di Cadagno is still today an example of a lake without mixing and therefore of interest for biological research.
