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.
