The Aschauer Ache , in the lower reaches of the Reither Ache , sometimes also Reinache or Spertner Ache, is a 23 km long left tributary of the Großache in the Kitzbühel district in Tyrol . It has a tributary of the confusable name Aschauer Bach , which streams carry elsewhere.

course

The Aschauer Ache is the result of the union of Oberer-Grund-Ache and Unterer-Grund-Ache south of Aschau in Spertental in the Kitzbühel Alps . The Unterer-Grund-Ache rises below the violin at a height of 2001  m above sea level. A. ( 47 ° 18 ′ 32 ″  N , 12 ° 15 ′ 21 ″  E ) and has a length of 10.3 km. The source of the 7.2 km long Oberer-Grund-Ache lies at an altitude of 1693  m above sea level. A. below the Stangenjoch in the Salzburg area ( 47 ° 19 ′ 39 ″  N , 12 ° 19 ′ 2 ″  E ).

The Aschauer Ache initially runs in a northerly direction through the Spertental . At Kirchberg in Tirol it reaches the Brixental and makes a sharp bend to the east. A valley watershed runs west here, separating the Aschauer Ache from the catchment area of ​​the Brixentaler Ache flowing towards the Inn . After a few kilometers it turns north again, flows through Reith bei Kitzbühel and is called Reither Ache in the further course . To the east of Going it takes up the Goinger Hausbach coming from the Wilder Kaiser and flows back east into the Leukental . On the southern outskirts of St. Johann in Tirol it flows into the Großache , which is still called Kitzbüheler Ache here.

Catchment area and water supply

The catchment area of the Aschauer Ache measures around 148 km² and extends from 664  m above sea level. A. (mouth) up to 2366  m above sea level. A. ( Great Rettenstein ).

The mean discharge at the Kirchberg gauge, 14.4 km above the mouth, is 3.08 m³ / s, and at the Sperten gauge just before the mouth it is 4.93 m³ / s, which equates to a discharge of 38.9 and 33.4 l respectively / s · km². The Aschauer Ache has a similar discharge regime , which is characterized by the snowmelt in the higher elevations of the catchment area. The mean discharge at the Sperten gauge is almost five times higher in the month with the most water in May (9.31 m³ / s) than in the month with the least water in January (2.01 m³ / s).

environment

The headwaters are in the conservation area Spertental-Rettenstein and relatively unspoiled. The banks of the Aschauer Ache are partially built up, in the local areas of Kirchberg, Reith and St. Johann even continuously. In the upper reaches, the Ache has water quality class II, below Reith class I-II.

Economic use

Three diversion power plants use the water of the Aschauer Ache to generate electrical energy. Water for snow-making systems in the Kitzbühel and Wilder Kaiser ski areas is taken from two places .
