The Weißache im Chiemgau , also called Weisse Achen , Weißachen and Weisse Ache, is a river in the Upper Bavarian district of Traunstein , which finally flows into the Chiemsee in the Rothgraben from the south near Grabenstätt .

geography

course

The Weißache arises in the Chiemgau Alps on the eastern slope of the 1784  m above sea level. NHN high Hochgern in the municipality of Ruhpolding and initially runs approximately east-northeast, with the area of ​​the municipality of Bergen on the left . Before the Rötlwandkopf, which is at the lower western drop of the 1674  m above sea level. NHN high Hochfelln , it avoids to the left, then flows through the Bergen area approximately northeast and passes the first desert areas of the community. At the foot of the hamlet of Pattenberg, on the left on the slope, it changes its direction back to east-northeast.

In the southernmost part of the settlement Mühlwinkl of the parish village of Bergen itself, it leaves the Alps in a left curve, then flows much flatter northwest through the associated village of Weißachen to the edge of the Bergener Moos and then moves west along the northern edge of this nature reserve. With the Schlagbach it takes its first major tributary from the right, which is fed, among other things, by the Bergener Bach from the Alps. After the inflow of the Buchbach stream from the left, it runs in the Sossau Canal north-west through the Grabenstätter area, with the Sossau Filz and Wildmoos nature reserve on the right . Right at the beginning of this canal, the Almbach flows from the left, which emerges as Blassenbach near Staudach in the foreland, and then further downwards from the right the Aitrach, which is also called Gleißing in one section.

The Weißache in the Sossau Canal approaches the Tiroler Achen in the west up to about half a kilometer and then flows parallel northwards in the Rothgraben , west of which the community Übersee extends, first on the eastern edge of the mouth of the Tiroler Achen nature reserve , and finally in it to the confluence with the Hirschau Bay of the Chiemsee near Grabenstätt-Hirschau immediately east of the wide, forward delta of the Tiroler Ache.

The Weissache only reaches the longer tributaries in the foothills of the Alps.

The Rothgraben section of the Weißache, also known as the Rothkanal , is just under 5 km long, the Sossau Canal previously just under 2 km. The total course of the Weißache has a length of 21.7 km, flows one after the other in the municipal areas of Ruhpolding , Bergen and Grabenstätt and finally borders that from overseas .

At the confluence with the Chiemsee, the Weißache has quality class II.

Catchment area

According to the official waterway map, the catchment area of ​​the Weißache is 72.3 km², elsewhere an area of ​​only 18 km² is given (with a more concise definition of the river section, since the Sossauer Canal / Rothgraben, for example, is shown separately there) or 70 km². (probably rounded).

Its southern part is predominantly forested except for a few alpine pastures and , in terms of natural space , belongs to the Chiemgau Alps , its northern part is sparsely forested, characterized by felts and belongs to the pre-alpine hills and moorland of the Bavarian Alpine Foreland . The highest point on the summit of the Hochgern reaches 1784  m above sea level. NHN , the confluence with the Chiemsee is 518.2  m above sea level. NHN .

history

The Weißache originally took the Aitrach from the right at the southeastern foot of the Osterbuchberg, shortly afterwards the Krummbach, which is now the dead straight Buchbach, from the left, then flowed westwards along the south side of the Osterbuchberg along roughly the route of the lower Almbach and then flowed out at the southwestern foot of the Einzelberg opposite the Überseer village Almau in an oxbow lake of the Tiroler Achen. To relieve them, the canal train from Sossauer Canal and Rothgraben was created in the first half of the 20th century, which increased the length by about five kilometers.

    then change to the foothills of the Alps.
  • Schlagbach , from the right near Bergen-Hautzenbichl and Grabenstätt -Fiegeneck; takes up the Bergener Bach
  • Book Bach , but drainage of the left common underflow from Madereybach and Klauser Bach, the several streams resulting in the Alps also Krummbach from Bergen moss and at staudach-egerndach combine -Bayern in the foothills
    Hereinafter flows Weißache in Sossauer channel
  • Almbach (upper course name: Blassenbach), from the left to the beginning of the Sossau Canal near Grabenstätt-Osterbuchberg
  • Aitrach (on one section also: Gleißing), from the right in the Sossau Canal section near Grabenstätt-Sossau; arises near Bergen- Bernhaupten
    After passing the Sossauer Filz (part of the nature reserve Sossauer Filz and Wildmoos ) the Weißache flows northwards in the Rothgraben with an inflow only from short drainage ditches.
