The diagram shows the course of the Windauer Ache, which flows in a northerly direction - from the Salzburg border to Hopfgarten.
|Location||in the Windautal / Kitzbühel Alps, Austria|
|Main source||Rainkarsee on the Kröndlhorn
|River mouth||In Haslau / Hopfgarten into the Brixentaler Ache
|Progression||Brixentaler Ache → Inn → Danube → Black Sea|
|Landmarks||Villages: Westendorf and Hopfgarten|
The Ache rises on the Rainkarsee at about 2,200 m AMSL and its middle reaches run through a roughly 4 km long gorge. In Hopfgarten the Windauer Ache discharges into the Brixentaler Ache at a narrow point in the valley; the Brixentaler Ache in turn empties into the River Inn at Wörgl.
The Windauer Ache is very popular for whitewater canoeing (grade WW II to WW V).
At the end of July 2006, bad weather in the entire Windau valley caused enormous damage. The Windauer Ache burst its banks and bridges, linings and sections of road were torn away.
The cost of repairing the damage - and the associated lining and regulation of the river - ran to some €860,000.
