Lake Malghette is an alpine lake in the northwest of Trentino. It is located in the Val Meledrio at 1890 meters above sea level, in the natural park Adamello-Brenta.
The water of the lake is used to supply the aqueduct of Campo Carlo Magno and Folgarida. It is a reservoir of natural origin. It is located in the Adamello-Brenta Natural Park, in the upper Meledrio valley, in an environment dominated by coniferous forests and meadows, on a terrace overlooking the north of the Brenta Dolomites to the east. To the west it is dominated by Monte Nambino, Cima Lasté and Cima Artuick. Near the lake there is a refuge and the remains of the Malga Piano.
It can be reached on foot from the village of Campo Carlo Magno, or alternatively from Malga Dimaro or Malga Zeledria.
