The Brixentaler Ache is a right tributary of the Inn . It is located in Tyrol , Austria and flows through the districts of Kitzbühel and Kufstein . According to the drainage area (330.3 km²), the Brixentaler Ache is one of the largest tributaries of the Inn in the Tyrolean lowlands , but it is only 28 km long.
The course of the river
The Brixentaler Ache rises as Brixenbach in the municipality of Brixen im Thale and flows westward through the Brixental . The valley floor narrows between Westendorf and Hopfgarten im Brixental . Immediately after this narrowness, the Windauer Ache flows into the Brixenbach when coming from the south. From this point onwards, the Brixenbach is now known as the Brixentaler Ache. After about a kilometer, the even larger Kelchsauer Ache (also coming from the south) joins . The approximately 26 km long Kelchsauer Ache drains the entire Kelchsau .
Between Hopfgarten and Kirchbichl or Wörgl, the Ache conquers another narrow valley before it leads through a flat foothill of the Inn valley. When leaving the narrow area, the Ache is dammed by a large weir and part of the water is channeled into a canal. This leads to a small TIWAG power plant . Below the weir, the Luecher Bach flows from the north in the direction of Söll ( Sölllandl ). After having been fed by so much water from the large tributaries, the Ache now dominates the landscape of the broad and densely populated Brixental. After the now around 16 m wide Brixentaler Ache has flowed through the border area between Wörgl and Kirchbichl, it flows into the Inn from the south .
The drainage area includes a relatively large area, particularly due to the largest tributaries Windauer and Kelchsauer Ache, which encompasses around a third of the Kitzbühel district.
The origin of the Brixentaler Ache lies in the Brixenbachtal (municipality of Brixen im Thale).

Flood
The Brixentaler Ache rarely overflows its banks; the most frequent floods occur in the area where it flows into the Inn near the Wörgl district of Söcking and opposite in Angath . During the flood of the century in 2005 , the Brixentaler Ache, which had an extraordinary amount of water, was dammed up at its mouth by the flood-bearing Inn, flooding large areas and causing immense damage.
Constructions
There were already numerous constructions in earlier times, in particular through the village of Hopfgarten and the lower Brixental near Bruckhäusl (Kirchbichl and Wörgl). In the meantime there are only a few untouched river kilometers, such as in the narrow area below Itter. Due to the recent floods, precautions have also been taken on the Kelchsauer, Windauer and the lower Brixentaler Ache. At the confluence of the Brixentaler Ache in the Inn between Angath and Wörgl, high earth dams were built on both sides of the Ache after the 2005 flood to prevent the water masses from repeatedly crossing the banks prematurely.
Between 2009 and 2011, at the end of the Itter Gorge, as part of one of the largest power plant construction sites in Tyrol, a new hydropower plant was built by TIWAG , which was built for 16.9 million euros instead of the old power plant. A new inflatable weir (by the way the largest inflatable weir in Tyrol) with three desanding chambers , a new pressure pipeline with a diameter of 2.4 m and a total length of 2,181.6 m and a new power station building were built. It is considered a showcase project of the union between ecology and economy , as the landscape is to be significantly improved compared to the old building. The new building more than doubled the power plant capacity to 15.8 million kilowatt hours . This means that 4,000 households can be supplied.
