The Weißach is a river in Miesbach in Upper Bavaria. The Weißach drains the complete Kreuther valley and empties into the Tegernsee.

Course

Has its origins Weißach in the blue mountains north of Lake Achen from dozens of sources Großweißach whose highest source is at 1347 m above sea level ( near the decrepit high -Alm, north of the barley Rieder head). Only from glassworks in the village of Kreuth the river is called Weißach. From there to the mouth of the Tegernsee the Weißach is 18 km long. Until Rottach -Egern the Weißach flows along the B307 and is largely embanked from Wildbad Kreuth.

The Weißach runs in the municipal district of the municipality Kreuth. From the Kreuther district Enterbach or the Rottach- Egerner district Trinis forms the right bank to the mouth of Weißach the local boundary between the two communities.

Inflows

The Weißach has a number of larger and smaller tributaries. Among the most important

• Albert Bach ( mouth height Trifthütte or WoodyStock Winterstube 840 meters above sea level. ) - right tributary
• The Schwarzbach ( mouth to 830 m above sea level. ), which drains the Black Entenn - left tributary
• The Klammbach ( Drained the territory of the king -Alm, muzzle at 814 m above sea level. ) - right tributary
• The Hofbauernweißach ( Drained the north side of the Blue Mountains, muzzle at 796 m above sea level. ) - right tributary
• The Sagenbach ( flows through the Long Au, muzzle at 790 m above sea level. ) - right tributary

Among the smaller tributaries include the rivers of Reitbach (r ), cut Bach ( l), carbon work digging ( l), Bart trench ( r), Alpelgraben and Rotmarterlgraben ( l), hunters conducting trench ( l), Böckleitengraben ( l), Laimbach ( l), Grüneckgraben ( l), Plattiger trench ( l), Gern mountain trench ( r), Rötzleitengraben ( l), perennial stream ( l), Ried Lerner trench ( r), Mühlauer trench ( r), Pletscherergraben ( l), Lahn trench ( r), Gschwend trench ( l), Klafferbach (r ), Meadow trench ( l), Brunntalgraben (r) and Grabenbächl ( l). In addition, the Weißach has other small tributaries. *

Flow obstruction

The Weißach was largely developed in the early 20th century for the Holztrift and flood protection. Here, the river was dammed and straightened over large parts. Wooden or concrete sleepers were built at regular intervals to prevent the erosion by the resulting increase in flow velocity. These thresholds were replaced between 1985 and 1995 in the middle course of the river by other engineering measures such as the use of riprap. In the lower course from the so-called Iron Bridge a significant deepening of the river bed was made in the following years for flood protection.

To compensate for the increased obstruction by the bed load transport and to prevent silting of the ring lake is dredged at the mouth of Weißach in the Tegernsee regular gravel.

At the height of the so-called Iron ridge there is a weir which dams up the water of the Weißach and a canal on the left side of the river, called the Mühlbach supplies. The Weißachmühle lying on the channel is used by the power station Tegernsee as a hydroelectric power plant to generate electricity since 1956. Below the weir is due to the water drainage into the canal for several months in very little water in the Weißach. The channel is not passed back to Weißach but flows south-west of Weißachmündung in the Ringsee.

History

The Weißach served as a transport route for spruce, which was mainly required for the firing of the Saline Rosenheim. The wood was " getriftet " to about Weißach, the Tegernsee and the Mangfall to its destination.
