Detailed map

The Göscheneralpsee is a reservoir in the municipality of Göschenen in the Swiss canton of Uri , which is used to operate the Göschenen power plant and is located in the Uri Alps at 1792  m above sea level. M. height is.


The reservoir can be reached from Göschenen through the Göschenertal . The 11 km long road was built in 1944. The Göschenertal lies between the Susten Pass and the Furka Pass . Around the lake are the peaks Sustenhorn (3503 m high), Dammastock (3630 m) and Galenstock (3586 m).


The lake was created as a replacement for the unrealized reservoir in the Urserental , which would have been used to operate the Urseren power plant . Soil mechanical investigations were carried out from 1952 to 1955 . In 1960 the dam on the Göscheneralp was completed. The former settlement of Göscheneralp, namely Hinteralp , nine kilometers west of Göschenen, has disappeared in the reservoir. The houses and the church were dismantled and flooded. Its residents moved to the hamlet of Gwüest, which belongs to the municipality of Göschenen .

The dam is designed as a planted earth dam, the wall height is 155 m, the dam crown is 540 m long. The dam is 700 m wide at the foundation. The storage basin with a capacity of around 75 million cubic meters collects the water from the Göschenertal, the Voralptal - a northern side valley of the Göschenertal, and from the upper  Urserental . The Chelenreuss and Dammareuss from the upper Göschenertal flow directly into the storage  basin , the  Voralpreuss and Stockbach are captured and fed  into the reservoir through the Voralpental feeder. The water of the Furkareuss also reaches  the lake  from a water intake at the Tiefenbach train station   via the Hinteres Urserental supply line  . This supply also receives water from the water intake of the Lochbergbach above  Realp . The reservoir supplies the Göscheneralp – Göschenen stage of the Göschenen power plant with water.
