The Söllbach is a 13.0 km long mountain stream in Bavaria and after the Weißach the second largest tributary of the Tegernsee in terms of its length and the third largest in terms of its sub-catchment area after the Rottach , into which it flows approximately northeast in Bad Wiessee flows out.

geography

Headwaters

The larger upper course of the Gurnbach of the Söllbach arises below the Seekarkreuz summit ( 1601  m above sea level ), on whose eastern slope the source of its longest source brook at around 1455  m above sea level. NHN rises above the Rauhalm von Lenggries. The Gurnbach initially flows in a winding course approximately eastwards, after the upper tree line it crosses the municipality and district boundary from Lenggries in the Bad Tölz-Wolfratshausen district to Kreuth in the Miesbach district and then reaches less than two and a half kilometers east of the highest spring mentioned in front of the waterworks at the Gurnbach-Holzerstube the bottom of the high valley, in which the Schwarzenbach moves southeast to the Weißach. The Gurnbach itself, on the other hand, bends there to around 1030  m above sea level. NHN to the north.

After about a kilometer in this new direction, it flows at 971  m above sea level. NHN with the shorter and less catchment area Raffelgraben , which with its longest upper course on the east side of the saddle between Brandkopf ( 1569  m above sea level ) and Spitzkamp ( 1603  m above sea level ) up to 1496  m above sea level. NHN arises, but is inconsistent on the first half kilometer of its fairly steady eastward moving run to the Mühltalalm. With the confluence of the two upper reaches of the river called Söllbach is created, which initially continues in the direction of the Gurnbach.

course

For the first one and a half kilometers from the east to the Luckengrabenalm, the Söllbach takes on the Luckengraben, which arises north of the top of the Hirschberg , then the Stinkergraben, which is approaching from the west on the municipal boundary to Bad Wiessee , so named because of the smell that the runoff from a sulfur water source on the middle course of the stream.

From there, this border initially follows the stream, which now swings to the northeast, which is fed from the left by Neuhüttengraben, from the right by the small Windberggraben and again from the west by the Scheibengraben, which arises on the southeast slope of the Fockenstein ( 1564  m above sea level ). At the tributary of the streams Wurzengraben from the south and Aueralpengraben from the west, which flow shortly one after the other before and after a waterworks, the Söllbach already runs within the Wiesse municipality area.

Shortly before and after a third waterworks then flow at heights between 810 and 805  m above sea level. NHN the Mühlbach from the right and the Saurüsselgraben and the Bucherschlaggraben from the left, this is the last noteworthy tributary of the loop-rich run from the valley forest into the settlement area of ​​the brook after another one and a half kilometers, which now enters the village of Bad Wiessee on the banks of the Tegernsee. In Bad Wiessee, the open brook crosses the federal highway 318 . It finally flows at the tip of the alluvial fan , which it has heaped like a nose into the lake, in the district of Abwinkel at 726  m above sea level. NHN high standing Tegernsee . At the mouth there is a fish hatchery of the Upper Bavaria State Fisheries Association and a large public aquarium with local fish from the Tegernsee.

The 13.0 km long stretch of water from Gurnbach and Söllbach empties about 729 meters below the highest Gurnbach spring and about nine kilometers northeast of its headwaters. Its mean bed slope on the entire route is around 76 ‰.

Catchment area

The Söllbach drains an area of ​​24.1 square kilometers north of the Roßstein in the Tegernsee Mountains , a maximum 4.5 km wide, but mostly narrower tube around the overall course, which runs somewhat northeastwards. The highest point is the summit of 1620  m above sea level. NHN Schönbergs on the southwestern tip. Apart from the highest locations above the tree line and the relatively wide shoreline at Tegernsee, it is almost completely forested.

From the Schönberg to the Fockenberg, the streams on the other side of the western ridge, mainly the Almbach and the Hirschbach , drain to the Isar in front of the church village Lenggries . On the second section of the left watershed on the north-west side, the Steinbach also competes outside, also to the Isar, now after the church village, then the Zeiselbach, which also flows into the Tegernsee in Bad Wiessee .

On the other hand, the brooks that emerge on the other side of the right watershed briefly in the south and then long in the south-east drain almost all of them to the largest Tegernsee tributary, Weißach , the largest of which are successively the Schliffbach , Schwarzenbach , Gschwendgraben and that itself only on the bottom of the Weißach Valley running, but some mountain streams absorbing meadow ditches .

Drain

With normal discharge, the Söllbach only carries around one cubic meter of water per second. Because of the steep gradient and the resulting high flow velocity, however, after heavy rain in the estuary, discharge rates of 20 m³ / second occur, a maximum of more than 44.1 m³ / second was measured on May 21, 1999. In 2006 and 2007, extensive construction measures to protect against blockage and to protect banks were therefore undertaken.

The water level of Söllbachs is a level detected in the state Bavarian water management administration and read out via remote data transmission. The official measuring system with a level zero point of 731.19 meters above sea ​​level is around 350 meters from the confluence with the Tegernsee. The mean water level is 20 centimeters, the flood of May 1999 reached a maximum of 1.73 meters.
