The Triftwasser is an approximately 10 kilometer long tributary of the Gadmerwasser in the Oberhasli in the canton of Bern in Switzerland .

geography

course

The wild river rises below the Trift glacier on the north side of the Winterberg massif and initially flows through the Triftsee at around 1660  m above sea level. M. , a natural lake near the border with the canton of Uri .

Around 2400 meters after the lake drains, the water is collected and used to produce electricity. The operator of the power plant is the regional company Kraftwerke Oberhasli (KWO).

After the Triftwasser flows into the Gadmerwasser , it reaches the Aare near Innertkirchen after a further 7 kilometers .

Catchment area

The 45.96 km² catchment area of ​​the Triftwasser is drained through it via the Gadmerwasser, the Aare and the Rhine to the North Sea.

It consists of 7.3% planted area , 2.4% agricultural area , 0.2% settlement area and 90.1% unproductive areas.

The area distribution

The mean height of the catchment area is 2436.4  m above sea level. M. , the minimum height is 930  m above sea level. M. and the maximum height at 3473  m above sea level. M.

Hydrology

At the confluence of the Trift water in the Gadmer water, its modeled mean flow rate (MQ) is 3.59 m³ / s. Its discharge regime type is a-glaciaire and its discharge variability is 13.
