Confluence of the Niedertalbach and Rofenache to the Venter Ache

The Venter Ache is one of the source rivers of the Ötztaler Ache in the Ötztal Alps  in Tyrol. Together with the Rofenache , it is often seen as the upper reaches of the Ötztaler Ache.

course

The Venter Ache arises from the confluence of the Rofenache and Niedertalbach  near Vent . The two source streams arise in the core area of ​​the Ötztal Alps and are fed by numerous glaciers, including the largest Schalfferner , Vernagtferner and Hintereisferner . The Venter Ache flows in a north-easterly direction through the Venter Valley , where it has cut deeply into the valley floor. At Zwieselstein  it joins the Gurgler Ache  to form the Ötztaler Ache. Its length is 13.7 km, together with the Rofenache 24.5 km.

Catchment area and water supply

The catchment area of the Venter Ache is 230.9 km², of which around 60 km² (26%) are glaciated. The highest point in the catchment area is the Wildspitze at 3768  m above sea level. A.

The Venter Ache shows a very strong glacial runoff regime with the runoff maximum in July. The mean discharge at the Vent gauge is 6.43 m³ / s (series 1951–1990), which corresponds to a discharge rate of 39 l / (s · km²). 87% of the annual runoff is measured in the months May to September.

Due to heavy rain, the Venter Ache at the old fire station gauge almost reached the HQ30 mark of the 30-year flood on August 5, 2016 .

use

The Venter Ache is one of the most valuable wild rivers in Tyrol . The white water is popular with paddlers and rafters. The level of difficulty ranges from WW II in the open sections to WW V in the Heiligkreuzklamm. The TIWAG plans to the river for the expansion of Gepatschspeicher to dam and drain the water.
