The Gentalwasser , in the Swiss national map Gäntalwasser , also Engstlenbach , is an approximately 14 kilometers long right tributary of the Gadmerwasser in the Swiss canton of Bern , which flows through the Gental in the Bernese Oberland .

geography

course

The wild river rises below the Joch glacier on the Wendenstock and initially flows through the Engstlensee , a natural reservoir near the border with the canton of Obwalden .

About 500 meters after the lake drainage, the water is collected and passed through a tunnel into the neighboring Gadmertal , where it is used by the Fuhren power station, which directs its underwater through a counterpressure tunnel into the shaft window of the Steinwasser – Trift intake tunnel. The water can then either be used in the Hopflauenen and Innertkirchen 2 power plants or pumped into the Räterichsboden reservoir via the pump turbine from Handeck 3 .

The Gentalwasser flows around 12 kilometers through the Gental and flows into the Gadmerwasser at the hamlet of Mühletal above Innertkirchen , which has covered approximately the same distance through the Gadmertal to this point .

Four kilometers later the Gadmerwasser flows into the Aare near Innertkirchen .

Catchment area

The 39.68 km² catchment area of ​​the Gentalwasser lies in the Urner Alps and is drained through it over the Gadmerwasser, the Aare and the Rhine to the North Sea.

It consists of 15.3% wooded area , 40.4% agricultural area , 0.5% settlement area and 43.9% unproductive areas.

The area distribution

The mean height is 1959.7  m above sea level. M. , the minimum height is 833  m above sea level. M. and the maximum height at 3015  m above sea level. M.

Hydrology

At the confluence of the Gental water in the Gadmer water, its modeled mean flow rate (MQ) is 2.48 m³ / s. Its discharge regime type is nivo glaciaire and its discharge variability is 17.
