Detailed map |
The Sufnersee is located in the canton of Graubünden in the area of the communities of Sufers and Rheinwald . The lake can be reached via the San Bernardino route. The A13 runs along the lake . The only place on the lake is Sufers.
The Sufers dam was completed in 1962. Around 30 hectares of meadow land were lost. To compensate for this loss, the existing humus was extracted from the storage space during construction and distributed over poor soil. With these soil improvements it was possible to increase agricultural production. There is no power plant at the lake, the water is directed to the Bärenburg headquarters or via the Lago di Lei reservoir and the Ferrera compensation basin to the Ferrera headquarters.
