Trängslet - the dam

The dam in Trängslet is the highest in Sweden, with its 120 meters.

The Trängslet dam was built 1955-1960. The dam also meant that the hitherto erratic flow of water in the river could be controlled. Upstream from the dam a lake has been formed which is 70 km long and contains 880 million cubic meters of water. Trängslet power station on the Österdalälven river uses a head of 142 meters to drive the turbines, each with its own generator. The power station is one of the largest in Sweden.
