The Gschnitzbach is a brook in Tyrol , Austria, which flows through the Gschnitztal and flows into the Sill in the Wipptal .
course
The Gschnitzbach rises from the Lauterersee below the Outer and Inner Wetterspitze in the Stubai Alps and then flows in a north-easterly direction through the Gschnitztal , passing through the towns of Gschnitz and Trins . After around 22 kilometers, it joins the Sill from the left at Steinach am Brenner .
In the first few kilometers the stream quickly loses height, it forms several waterfalls and flows through the Simmingsee . It has a gradient of 18.6% up to the Laponesalm after about 3 km of flow. From there, the average gradient flattens and is only 2.3%, over the entire course 4.4%.
Catchment area and water supply
The catchment area of the Gschnitzbach is around 112 km², of which 2.1 km² (just under 2%) are glaciated. The highest point in the catchment area is the Habicht at 3,277 m above sea level. A. The mean discharge (MQ) at the Steinach gauge, 240 m above the mouth, is 4.17 m³ / s, which corresponds to a discharge of 37.4 l / s · km². The runoff regime is typical for a mountain stream without glacial influence. The maximum discharge in June is more than seven times the minimum in February.

environment
The upper reaches are left in their natural state, from about the area around Gschnitz the human influence can be seen through bank construction, wastewater pollution and regularly fertilized agricultural areas.
The Gschnitzbach is a summer cold mountain stream with temperatures always below 13 ° C. The water quality class of the stream is in the entire course I to II and offers a good habitat for fish.
The Gschnitzbach very quickly turns into raging white water. The lower reaches in particular are riddled with rapids .
