The Stiefing is a left bank tributary of the Mur in the Austrian state of Styria . It forms a sole valley on the western edge of the East Styrian Riedelland and joins the Weissenegger Mühlkanal in Leibnitzer Feld , before it flows into the Mur after more than 41 km at Gabersdorf .
course
The Stiefing rises south of the Schemerlhöhe in the municipality of Nestelbach near Graz . As a Stiefingbach, it initially runs in a narrow ditch in a southerly direction and passes the former community of Edelsgrub . In Empersdorf the valley widens and the Stiefing takes on two of its larger tributaries, the Rettenbach (left) and the Stiefen (right). To the south of Heiligenkreuz am Waasen , the river curves in a south-westerly direction and the Stiefingtal opens up to the Leibnitzer Feld . Below the L663 , the largely natural course of the river joins the Weissenegger Mühlkanal , which is called the Mühlgang from the confluence in the ÖK .
The Stiefing passes the villages of Haslach , Ragnitz and Laubegg before entering the Mur floodplains west of Sajach. Then it flows completely canalised parallel to the Mur and flows into the underwater of the run-of- river power plant near Gabersdorf . According to the Styrian body of water index, the Stiefing is 38.4 km long, and 41.8 km in the Digital Atlas. This makes it the longest left tributary of the Mur on a stretch of 170 km between Mürz and Ledava . As can be seen from the Josephine land survey , the mouth was a few kilometers further north near Sajach in the 18th century before the Mur regulation was introduced.
Flood
There are extensive agricultural areas along the Stiefing, which are often affected by floods , especially on the Leibnitzer Feld . It is there that the floodplain overlaps with that of the Mur catchment area and, in extreme cases, backwater through the Weissenegger Mühlkanal can occur. Several discharge studies have already been carried out on behalf of the State of Styria and the Federal Water Management Authority. The flood at the end of June 2009, with a discharge of 70.8 l / s at the Gerbersdorf gauge (municipality of Sankt Georgen an der Stiefing ), corresponded to a 70- year event (HQ70). The flood areas of that summer could be verified with a hydraulic model, according to which around 190 objects were in the danger zone at HQ100. In the future, priority areas are to be kept free for flood protection between developed plots .
Water quality
In the summer of 2018 were commissioned by Greenpeace total of 29 rivers in several EU contamination by -countries regard factory farming investigated. In addition to the Schwarzautal, the study authors chose the municipality of Sankt Georgen an der Stiefing in Styria , where 15,000 pigs live around ten times as many pigs as people. The water sample from the Stiefing district revealed contamination with five different veterinary drugs and 38 pesticides , including twelve that are no longer permitted in the EU. The two authors called the determined concentrations of clothianidin , nicosulfuron and terbuthylazine " ecotoxicologically questionable" and saw possible damage to aquatic organisms. The nitrate value was below the EU limit value (50 µg / l), but above the critical concentration for amphibians and aquatic invertebrates (9 µg / l).
The Ministry of the Environment rejected the allegations against agriculture based on the measurement results on the grounds that the investigations did not meet the "usual scientific criteria". The antibiotic residues also came from human medicine .
Cultural landscape
The Stiefingtal is predominantly agricultural from the source to the mouth. In addition to maize and other types of grain, pumpkins and oil fruits are primarily grown . In many places, natural vegetation accompanying the stream has been preserved along the river. The artificially created lower course, which was mainly fed by the Mur (Weissenegger Mühlkanal), provided space for mills in earlier centuries . The Ragnitzmühle, for example, an archaeological site in 1870, dates from the 17th century and is still in operation today. In addition, several run-of- river power plants were built on the Mühlkanal , two of them in the municipality of Gabersdorf.
In November 2007, eight municipalities merged to form the “Kleinregion Stiefingtal”. The joint development concept adopted in 2010 provides for closer integration of the social, economic and recreational areas. Specifically, goals such as widening the river strip and improving technical flood protection along the Stiefing are being pursued. In addition, the Stiefingtal cycle path (state cycle path R50) is to be expanded. The most important component is the climate and energy model region Stiefingtal with the primary goal of being completely energy self-sufficient by 2025 .
