Lago d'Isola, reservoir at San Bernardino, Grisons, Switzerland
Lago d'Isola is a reservoir in Mesocco in Grisons covering about 39 hectares at an elevation over 1,600 meters. Clear water is surrounded by hills and mountain ranges, forming a calm surface that reflects the sky and nearby peaks.
The lake was built as a dam to store water for electricity generation and manage water resources in the region. This development is part of Switzerland's efforts over many decades to use natural sources like rivers and lakes for energy and supplying communities.
The name Lago d'Isola comes from Italian and reflects the linguistic diversity of the Grisons region. Today the water is part of daily life in Mesocco, serving as a place for traditional activities like fishing and walking that keep the community connected to nature.
The site is easily accessible by car and visitors can walk along simple paths beside the water, especially on warm summer days. Those wanting to boat or sail should check availability in advance since water sports are seasonally limited.
An arched dam at one end of the lake stands about 45 meters tall and crossing it offers a fantastic view of the mountain pass and Pizzo Uccello with its cone-shaped peak. This special vantage point is not known to many visitors who come to the water.
