The Krumme Steyr is a 5 km long left tributary of the Steyr in the Totes Gebirge in Upper Austria .
course
The Krumme Steyr rises between Unterer and Oberer Salmeralm on the eastern slope of the Great Priel in the Dead Mountains. It initially flows steeply over steps and waterfalls south into the valley and then turns east on the wide valley floor. In the cushioned gap, it feeds the artificially created Schiederweiher via a ditch , which flows below into the Krumme Steyr. About 300 m further on, the river flows into the Steyr from the left.
Catchment area and water supply
The catchment area of the Krummen Steyr measures 20.7 km² and extends over around 1900 meters in altitude to the Großer Priel ( 2515 m above sea level ). The mean discharge at the Polsterlucke gauge is 2.31 m³ / s. The extremely high discharge of 148 l / s · km² can be explained by the fact that it is a karst area and the actual underground catchment area is considerably larger than that corresponding to the surface relief. The strong fluctuation in runoff with precipitation and snowmelt in spring can also be attributed to the location in the karst. The month with the most discharge is June with an average discharge of 6.70 m³ / s, more than fifty times the month with the lowest discharge, February (0.13 m³ / s).
nature
The entire course of the Krummen Steyr is very close to nature. Wide relocation stretches, on which the gravel beds fall completely dry at low tide, alternate with calmly flowing deep sections. The bank areas consist of various ecologically valuable grassland areas, which are characterized by the gravel soil and flooding.
