Detailed map |
The Lai da Marmorera is a Swiss artificial lake in the canton of Grisons in the municipality Surses that the Mittelbünden power plants of the power station of the city of Zurich is operated (EWZ). It can be reached from Tiefencastel or from the Engadin from the village of Silvaplana over the Julier Pass . The only village on the lake is Marmorera . Above the western end of the dam are the ruins of Marmels Castle .
history
The Marmorera Dam (Castiletto) was completed in 1954. The old Marmorera was flooded after the main buildings were blown up. The new Marmorera was built above the reservoir and the Julier Pass road. Many residents preferred to move away for economic and emotional reasons.
Diving
The Lai da Marmorera is often visited by divers in summer and autumn, as it offers ideal conditions for mountain lake diving : crystal clear water, remains of the sunken village and an approach that does not lead over any passes from the north. There are two safe and easily accessible dive sites : the first below the “Marmorera Dorf” post bus stop and the second near the Julier Bridge at the southern end of the lake.
