The Tauernbach is a brook in East Tyrol and, along with the Kalserbach and Schwarzach, is one of the most important tributaries of the Isel . The Tauernbach rises at the end of the Tauern Valley below the Alter Tauern (near Felber Tauern ) at an altitude of 2270 m and flows steeply downhill. At an altitude of about 1580 m of Tauernbach between the Außergschlöß and Wohlgemuthalm in the much larger flows Gschlößbach . Nevertheless, the river that emerged from the confluence of the two streams is referred to as the Tauernbach in the following. At Matrei in East Tyrol the Tauernbach finally flows into the Isel after 18.02 km and after overcoming an altitude of 1340 meters.
geography
geology
The Tauernbach mainly flows through layers of crystalline slate from the Tauern window . In sections it also crosses layers of granite and gneiss . In the area of the confluence with the Isel, however , the Tauernbach runs gravel and sand layers that have already overlaid the geological formation of the Matrei strata.
course
The Tauernbach rises at the beginning of the Tauerntals on the southern slope of the age and Felber Tauern in 2270 m height. Then it runs steeply downhill and takes up the Dichtenbach in the so-called wooden floor forest. After a little more than three kilometers, the Tauernbach flows into the much more powerful Gschlößbach at the beginning of the Gschlößtal . This has its origin in the confluence of the Vilhabenbach (source area: Vilhabenkees) and the Schlatenbach (source area: Karleskees). Probably due to the names of the valleys, from the confluence of the Tauernbach and the Gschlößbach (the beginning of the Tauern Valley) the resulting river is named Tauernbach. As a result, the Tauernbach forms a strong leveling that extends to the Moaralm. The hamlet of Tauer ( 1511 m ) and the Matreier Tauernhaus are also located here . Then the Tauerntal narrows like a gorge and the Tauernbach flows near the Felbertauernstraße to the Kalser Alm. Shortly thereafter, the Tauernbach takes on the Landeggbach and continues to flow a little further along the Felbertauernstraße to the Unterwaldalm, where the valley extends to the hamlet of Raneburg ( 1268 m ) widens. From here the course of the road again approaches the Tauernbach, which is due to the narrowing of the Tauern Valley as far as the hamlets of Berg ( 1272 m ), which is slightly above the creek, and Gruben ( 1150 m ). At Gruben, the valley widens to the Gruben pumping station ( TAL transalpine oil pipeline ). Then the Tauern valley narrows again and the Tauernbach flows below the hamlet of Lublaß ( 1148 m ), after taking in the Steiner Bach with the famous Steiner waterfalls , into the Prosseggklamm . In the village of the same name Prossegg (945 m), the Tauernbach has already covered most of its gradient and now flows straight through the heavily used agricultural area. It now passes Matrei at the western end of the village and flows into the Isel after the Bretterwandbach creek has been taken up .
Tributaries
A total of 14 rivers flow directly into the Tauernbach. In terms of their catchment area, the Gschlössbach , Frosnitzbach , Landeggbach , Bretterwandbach and Steiner Bach are the largest tributaries of the Tauernbach. The five largest tributaries have tributaries just like the Petersbach itself.

environment
fauna and Flora
In the area of origin of the Tauernbach there are dwarf shrub heaths and alpine grass communities in particular . Above Aussergschlöß (along the Gschlößbach ) and downstream to the Moaralm there are mainly extensive alpine pastures . The Tauernbach gorge stretches are overgrown by conifers on the western slopes of the valley , and deciduous trees also exist at the upper limit of the steep step . The opposite side of the valley, however, is mostly a bit flatter and mostly overgrown with deciduous trees. As far as Prossegg, the western valley slopes in particular are cultivated, while monthly spruce forest dominates the eastern slopes and is only rarely interrupted by green spaces in the valley areas. The extensive widening area of the Tauernbach below Prossegg to the estuary, however, is largely used by agriculture on both banks .
The fish passability of the river is mainly interrupted by the Prosseggklamm (waterfalls, weir system) and the gorge stretch above the Wohlgemutalm. Fish deposits in the Gschlößbach and in the area of the " Matreier Tauernhaus " are therefore probably due to occupations. The main species of fish that occur are brown trout , char and occasionally rainbow trout and grayling (lower reaches).
natural reserve
From the confluence of the Keespölachbach upstream, the Gschlößbach is part of the Hohe Tauern National Park (outer zone or core zone). From a nature conservation perspective, the Prossegg Gorge is also important. In addition, some of the tributaries are rated as worthy of protection, such as the middle course of the Frosnitzbach and the high mountain stretches of the Landeggbach, Steiner Bach and Gschlößbach (rivers of flowing water in the high valley). The Tauernbach is an important habitat of the German tamarisk (Myricaria germanica), which is why conservationists have been calling for the Tauernbach to be designated as a Natura 2000 protected area for years . At the end of June 2015, however, the Tyrolean state government only reported areas of the Isel, Kalser Bach and Schwarzach as Natura 2000 areas. In the spring of 2017, however, the European Union called for additional glacier rivers to be nominated, including that of the Tauernbach.
Bank condition and building measures
The upper reaches of the Tauerbach (Vilhabenbach) is still natural up to the Schlatenbach estuary. From the Innergschlöß onwards , the river (here still Gschlößbach ) was built, straightened and straightened to gain and secure agricultural areas (extensively managed wet meadows ) and the course was restricted by longitudinal barriers. In addition, two sediment catchment basins were built (mouth Schlatenbach and Wohlgemutalm). In addition to the upper reaches, natural river sections have been preserved, especially in the gorge stretches , starting at the confluence of the Tauernbach in the Gschlößbach (to Wohlgemutalm) and in the Prosseggklamm, where short stretches of leveling are only built in at certain points. In the local area of Matrei, the Tauernbach is finally built with wood / block stone groynes or stone finishing.
Water quality
The Tauernbach has water quality classes I-II over its entire length . Soiling in the upper reaches is mainly caused by sewage pipes in the alpine area of the Innergschlöß , in the lower reaches the high number of sewage discharges in the area of Matrei is striking. Since the local sewer line is currently under construction and the collected waste water will be transported to the sewage treatment plant near Kienburg ( Huben ) in the future, an improvement in the water quality in the lower reaches can be expected.
economy
Energy use
Currently, the Tauernbach is only used for energy purposes on the lower reaches of the Prossegg Gorge. There the water is withdrawn with the help of a weir system 360 meters above the privately operated power plant , with the remaining water amount being around 70–80 percent. Currently, only 1.2% of the total length of the Tauernbach is used for energy purposes. However, TIWAG's plans to expand the use of hydropower on the Tauernbach go much further. TIWAG is currently planning a Matrei-Raneburg pumped storage power plant that will dam the Tauernbach above the hamlet of Raneburg by means of a 90-meter-high dam wall and provide a reservoir that will hold 20 million tons of water when it is fully flooded. This project, in the forecourt of the Hohe Tauern National Park , is not only met with massive resistance from environmentalists, the local population has already organized a citizens' initiative against the construction of power plants. The project is currently only supported by the ÖVP , SPÖ , Greens and FPÖ have already spoken out against it.
The 380 kV line from Kaprun to Lienz has been running through the valley since 1975 .
