The Steyr (debate? / I ) is a river in Upper Austria Pyhrn- Eisenwurzen, which rises in the Dead Mountains near the Baumschlagerreith in place Hinterstoder ( district of Kirchdorf an der Krems ) and 68 km away in the town of Steyr from left flows into the Enns.

Geography

In the upper reaches of the Steyr flows through the Stodertal. Below the Steyr mountain the valley narrows and the river flows through the Stromboding waterfall. From Steyrbrücke the way of Steyr performs a deep gorge that is flooded since 1975 by a dam with Klaus. The resulting Klauser lake is used in addition to the energy well as recreation area. The right lakefront belongs partly to the Limestone Alps National Park.

Beneath the Sanctuary of stone woman in Mollner district Ramsau is another gorge, called Steyr breakthrough. At the beginning of the gorge, the power plant Steyr breakthrough, which is known for its Art Nouveau architecture is. After Steyr breakthrough the valley widens to Mollner pool, in whose gravel terrace, the Steyr has cut deep.

Below the mouth of the Krumme Steyr Ling at Molln we find the runny wall, a rare Traufquelle. From porous conglomerate rock, water enters from five to seven meters above river level in the form of drizzle. It is to be stautes basic and slope water. In this section of the canyon alpine plants occur up to 400 m above sea level, such as Hairy Alpenrose, Dwarf Alpenrose, Petergstamm, Jägerblut or Behaarter Germer.

When Leon Stein (municipality Grünburg ) the valley is narrower again. About Grünburg the Steyr thereafter reaches the foothills of the Alps. In the town of Steyr, the river gives off a part of its water to the moat, used the earlier many farms to produce energy. At the mouth of the rivers Enns both form a "Y", which uses the Steyr for marketing purposes.

Formation

The drainage network of the Danube to the Steyr heard with tributaries and tributaries, arose in the course of alpidischen orogeny about 100 million years. Probably even before the Mindeleiszeit ( 600000-300000 years ago) the watershed at Steyr breakthrough was reduced until the Steyr river " break " could. Previously, he was draining off through today's Krems Valley. The present course of the river was built since the end of the Ice Age, about 11,000 years ago. The old valley gully, west of it, is filled by glacial gravel and the river tiefte instead in a so-called epigenetic breakthrough in the dolomite rock one.

The gorge systems of the Steyr and its tributaries Teichl and Krumme Steyr Ling are 30 to 40 meters high, partly overhanging conglomerate walls. The rivers deep to this day in the glacier rubble one.

Economic Importance

The Steyr was and is mainly used for energy. Previously, the direct drive, for example, mills or forging hammers, later to generate electricity.

By 1890, the river was traversed with shop Karl mentioned boards rafts. These rafts were on average 5 m long, 4 m wide and 50 cm high and could be controlled by a man. They were taken apart in Steyr mostly, but sometimes also bound to continue on the Enns to longer rafts. The table character of the shop Karl driver in the museum of the city of Steyr shows a model of such a raft in a Ein'gricht ( patience bottle).

By the end of the Second World War played on the Steyr and their tributary streams, the Holztrift as transport for sawmills a role. On the river approximately 30,000 cubic meters per year were from March to the end of November getriftet, for this reason, older dams (such as Steyr breakdown ) equipped with drift streets.

Prevented Recovery in the Enns

From 1963 Ennskraftwerke AG, auszuleiten some of the water over a large memory in the valley Krumme Steyr Ling in the Enns planned. The Mollner population rejected the project in 1969 with 2/3-majority, yet was begun with the construction. A decision of the Constitutional Court in 1972 interrupted the work and the organization Save the Steyr launched a petition. From project of pumped storage group Molln was built from 1973 to 1975 with the power plant Klaus only the first stage.

Sports

The river is very interesting for experienced kayakers and offers beautiful sections of WW2 to 3 .
