The Rotbach (in the upper reaches Zartenbach and Löffeltalbach , in the middle reaches Höllenbach ) is the 19.9 km long, left and southeastern main source river of the Dreisam in the southern Black Forest ( Baden-Württemberg , Germany ).
Zartenbach
The source streams of the upper reaches of the Zartenbach begin in the municipality of Hinterzarten ( Southern Black Forest Nature Park ) southwest of the Oberzarten district in the eastern steep slopes of the Ramselehöhe (1111.9 m) at an altitude of around 1085 meters. They gather at the bottom of a hollow valley formed by ice age glaciers with a stepped longitudinal profile. In one of the evacuations , the brook in the Mathisleweiher ( 999 m above sea level ) is dammed. Then it flows in a wide left curve around the Windeck ( 1209 m ) and flows northwards via Ober- and Hinterzarten into the extensive hollow of the flat Hinterzartener Moor ( nature reserve ).
Löffeltalbach
After the runoff of the western part of the moor has flowed towards it from the west, the brook sinks with a steeply steep slope into a notch valley, which is called the Löffeltal after the companies that used to make wooden spoons here . The Löffeltalsteige , the ascent from Höllental to the height of Hinterzarten , used to run through this valley .
Höllenbach
In Höllental, the Löffeltalbach joins the Ravennabach coming from the northeast from the Ravennaschlucht . Then the stream, now called Höllenbach , flows northwestwards through the straight trough valley of the upper Höllental valley, which is shaped by glaciers, and then a gorge-like section of the valley known as the Hirschsprung or Höllenpass . In Höllental, the stream is accompanied by the B 31 and the Höllentalbahn .
Rotbach
In the lower valley area it flows - henceforth as Rotbach - through Falkensteig and Himmelreich (districts of Buchenbach ), where it emerges into the plain of the Zartener Basin. North of Kirchzarten , the Rotbach joins above the bridge on Landesstraße 127 at 377 m above sea level. NN with the Wagensteigbach to Dreisam .
