== Background == In Hopfgarten im Brixental, the Kelchsauer Ache flows into the Brixentaler Ache. This is thus a large right tributary of the Inn River. The drainage area measures just about 138 square kilometres, all within the limits of the municipality of Hopfgarten. The Brixentaler Ache has an even larger catchment area of 329 square kilometres, being among the largest tributaries draining into the Inn on the Tyrolean Unterland side.

== Short summary and role == In short, the Kelchsauer Ache is a typical mountain river shaped by its high alpine sources and steep gradient with relation to the Kitzbühel Alps. It is important for the regional water cycle, serves as a recreational facility, and provides renewable energy to the locality.
