Lago di Palagnedra, Reservoir in Centovalli, Ticino, Switzerland

Lago di Palagnedra is a reservoir in the Centovalli, Ticino, Switzerland, formed by a 72-metre dam on the Melezza river completed in 1952. It holds 4.26 million m³ over a surface of 25 hectares, lies between Pizzo Ruscada and the Gridone, and is divided below the settlement of Borgnone by a weir.

The Palagnedra dam was completed in 1952 with a height of approximately 72 meters. Since its construction, the reservoir has served the region for more than 70 years in managing water flow and generating hydroelectric power.

The reservoir is named after the village of Palagnedra on the slope above it. It serves as a compensation basin for the Maggia Kraftwerke AG power plant at Brissago, collecting water already used for electricity generation in higher plant stages. Below the settlement of Borgnone a weir divides the lake.

The lake is readily accessible from the village of Palagnedra and offers quiet paths for walking along the water. Facilities are minimal in the immediate area, so visitors should plan to explore at a relaxed pace without expecting commercial amenities.

The railway connecting Domodossola in Italy to Locarno in Switzerland runs along the north side of the lake, offering daily travelers views of the water and surrounding mountains. This historic rail route creates an unexpected connection between two countries precisely at this location.
