Bridge of the Pyhrnbahn over the Steyrling

The Steyrling is an approximately 14 km long left tributary of the Steyr in Upper Austria .

course

The Steyrling rises in the sand ditch in the Dead Mountains at around 920  m above sea level. A. It initially flows north through a sparsely populated valley. At the confluence of the Höbach turns to the east and then flows through the village of Steyrling . Below the village it runs in a deep gorge and flows into the Steyr dammed up to Lake Klauser at Preisegg . The reservoir clearly protrudes into the Steyrlingtal. Shortly before the mouth, it is crossed by the Pyhrnpassstrasse and the Pyhrnbahn . The Steyrling runs entirely in the municipality of Klaus an der Pyhrnbahn .

The most important feeders are (downstream) Meisenbach, Hungeraubach and Fischbach from the right, as well as Zösenbach, Höbach and Traglbach from the left.

Catchment area and water supply

The catchment area of the Steyrling is 76 km². The highest point in the catchment area is the Teufelsmauer at 2185  m above sea level. A.

The mean discharge at the Steyrling gauge is 1.92 m³ / s, which corresponds to a discharge rate of 26.5 l / s · km². The month with the most discharge is April with an average discharge of 3.23 m³ / s, around three times the month with the lowest discharge, October (1.03 m³ / s) and January (1.08 m³ / s). Due to its location in the karst , the runoff is influenced by seepage, and in parts the Steyrling can fall completely dry.

nature

The course of the Steyrling is relatively natural for long stretches, only in the local area of ​​Steyrling is it continuously regulated with bank walls on both sides. In many places there are still wide gravel areas in which the river can change its course in a largely natural rhythm and thereby relocate the gravel areas. Such relocation routes have become rare in the Alpine region due to obstructions. On these gravel banks, a typical vegetation of alluvial find pioneer plants such as butterbur  and lavender pasture  over gray alder to spruce - lowland forests ranges.

The steep bank slopes in the lower reaches are covered with natural deciduous forest. This is where the ornamental anemone flower grows , which is found only in a few places in the northeastern limestone Alps . On the gravel areas in the estuary there is a small area of ​​gravel vegetation with butterbur.

The entire course of the Steyrling has water quality classes  I-II (as of 2007).

use

Like many streams in the wooded area, the Steyrling was also used for the wood drift . The wood from the forests in the catchment area of ​​the Steyrling was used for centuries for the production of charcoal. It was drifted to the Steyr and there, bundled in rafts, was transported further downstream. In order to have enough water for the Trift, weirs were built that enabled swell operation. Many of the Trift buildings have fallen into disrepair today, and some have been converted into torrent control. The lock in the Hungerau at the beginning of the Trift route was converted into a small power station and also serves as a bed load barrier for around 300,000 m³ of bed load.
