The Rantenbach , also known as the Ranten , is a left tributary of the Mur in the Upper Mur Valley in the Austrian state of Styria . It flows through the municipalities of Kraków and Ranten , before flowing into the Mur after a good 35 km in Murau .

course

Rantengraben

  • Rantensee versus Rantentörl

  • Upper course in the rear ditch

In its upper reaches, the Rantenbach is a small alpine torrent . It rises around 2050  m above sea level. A. in a Hochkar south of the Rantentörl  ( 2166  m ), on the main ridge of the eastern Schladminger Tauern between Predigtstuhl  ( 2543  m above sea level ) and Knarrnspitze  ( 2387  m above sea level ). After a short stretch of river it reaches, already at 1878  m above sea level. A. , the Rantensee, and then flows through the (Cracow) Rantental even Rantengraben called, in north-south direction. Smaller tributaries come from the Hinterkarsee and Mitterkarsee on the left side of the valley. The narrow valley floor is determined by alpine pastures and loose larch forest . In this section it is supervised by torrent and avalanche control . At running kilometer seven the Prebergraben (Preberbach , also Rantenbach) joins on the right .

Cracow high valley and Ranten gorge

  • In the Ranten Gorge

After nine kilometers of flowing, the Rantenbach enters the town of Moos  ( 1269  m ) in the Krakauer Hochtal (Krakautal) , where the Feisterbach from the Prebersattel joins from the right . In its middle course the stream runs mainly eastwards, Prebertal - Krakautal are part of the Murparalleltal . After the mouth of the Feisterbach stream, the stream passes two diversion power stations and forms the border between Krakauhintermühlen in the north and Krakauschatten in the south on the high valley floor, which is characterized by grassland .

After the village of Brandstatt  ( 1160  m ) the consistently wooded Ranten Gorge begins . The brook erodes here into the ice age gravel of the high valley and divides the valley floor between Ober- / Unteretrach and Krakaudorf into two terraces . The brook meanders in the 100-meter-deep gorge and forms impact and sliding slopes . Landslides often occur due to lateral undercutting . In the largely inaccessible gorge, the stream with the Etrachbach takes in a significant left tributary from the interior of the Tauern.

(Rantener) Ranten Valley

  • At Ranten -Löwenwirt

  • Estuary at Mursteg in Murau

After the Rantenbach near Seebach ( 961  m ) has left the Krakautal and merged with the   Seetaler Bach , its lower course flows through a wider valley, which is again called Rantental , and takes a southeastern direction. He passes the settlements of Ratschfeld , Ranten and Tratten . At flow kilometer 29, at Kulmhammer , the valley narrows again and the stream runs directly on Murtal Straße (B 96) . This narrowing of the valley is geologically unstable on the right bank , here is a large sliding slope (Lärchberg-Galgenwald) .

After another diversion power plant, the Rantenbach reaches the district town of Murau and flows east of the old town at 750  m above sea level. A. in the Mur .

Construction activities at the Krakautal-Rantenbach power station, 2015

Historically, there are nine iron hammers mentioned near Murau an der Ranten, which were made from the 15th century onwards in relation to the Erzberg . These are the Prixenhammer (urk. 1496–1923), Herrschaftshammer (1667–1876 / 81), Grüblhammer , Brucken - or Zeughammer , wire hammer with nail forge, field hammer , Heiligenstatthammer (until 1805) and the Kulmhammer (urk. 1602–1876 ). Most recently they were all owned by Schwarzenberg ( resident at Murau Castle since 1617 ). Another hammer was with Tratten. The address Am Hammer is a reminder of the city's works , while the Kulmhammer mansion is a listed building.

Today there are several powerful diversion power plants along the stream :

  • A predecessor of the  Murau power station was built in 1906. The power plant in its current form (net head 28 m, pipeline length 1500 m) was opened by the Murau municipal utilities in 2009 and is designed for a water flow rate of 5000 l / s. The two turbines with a maximum output of 1500  kVA can produce up to million  kWh annually and supply around 1000 households with green electricity .
  • The  Krakautal-Rantenbach power plant in Krakauschatten -Moos consists of two Pelton turbines and was completed in 2016. The system, which is equipped with a damper weir , has a consensus flow rate of 2200 l / s and supplies the Krakow municipality with energy.
  • Another power plant with a consensus volume of 3500 l / s is under construction near Seebach until the end of 2017.

nature

The headwaters are located in the Krakau – Schöder nature reserve  ( NSa 15 ), the entire upper course in the Lower Tauern European protected area  (VS, EU38 / AT2209000 ) and the Schladminger Tauern landscape protection area  ( LS11 ).

At the mouth of the river, the Upper and Middle  Rivers of the Mur are designated as a European protected area with Puxer Auwald, Puxer Wand and Gulsen (FFH, EU5 / AT2236000).
