Reservoir Gibidum

The Gibidum reservoir was first filled in 1969 after five years of construction. Its filling capacity is about 8.8 million cubic metres of water and the arch dam is 120 metres high. The maximum depth of the reservoir is 104 metres and it has an area of 21 hectares.

Melt water and sediments

It is fed by melt water from the Great Aletsch Glacier and other mountain streams. The special feature of the Gibidum reservoir is that around 65% of its catchment area is glaciated. The water is therefore rich in sediment, which causes heavy wear on the turbine wheels of the power plant. For this reason, the entire reservoir is flushed annually. For this, production is interrupted for two to three days.  

Adventure above the Gibidum reservoir

For those who like more adventure, the secured circumnavigation of the reservoir is recommended. The via ferrata leads around the reservoir for about 3.5 kilometres and offers dizzying climbing passages. As a special thrill, you can also expect an 80-metre-long and 40-metre-high Nepalese suspension bridge.
