The Eschach is a left tributary of the upper Neckar in Baden-Württemberg . Your around 210  km² large catchment area is located in the eastern slope of the Middle Black Forest between the valleys of Schiltach , Brigach and Neckar. The almost 38 kilometers long river has a gradient of about 130 meters. The Eschach has two source rivers: the larger Badische Eschach and the longer Württembergische Eschach .


Source rivers

The Eschach arises from two spring waters. The longer one is classified hydrographically as its upper course, the significantly richer one as its third important inlet.

Northern source river

The longest flow path begins today as Eschach (without name affix), after an older name as Württembergische Eschach or Horgener Eschach . It rises at the Heimliswald homestead in the district of Rötenberg von Aichhalden at 699  m above sea level. NHN and initially flows in a south-easterly direction. After the Eschach has bounded the Winzeln-Schramberg airfield to the west - the municipality of Fluorn-Winzeln borders there on the left bank - it is fed from the right by the Bannmoosgraben at 3.258 km of its course. At km 4.7, the Seltenbach also comes from the right before it runs along the northeastern edge of the Schramberger Heiligenbronn . The Mollenmoosgraben flows into it at km 6.13. At 8.1 km, at the turning point of a loop to the east, it reaches the center of Seedorf in the municipality of Dunningen , after which it continues to flow south.

At km 11.47 the Eberbach , also called Aitenbach , flows from the right . Shortly afterwards it crosses under the B 462 and then reaches Dunningen itself, which is almost entirely to the left of the river. After winding its way around several hills, it flows on its 20th kilometer along Lackendorf . In the now formed valley, it then passes the villages of Stetten ob Rottweil and Flözlingen in the municipality of Zimmer ob Rottweil . In Horgen, the last village in the valley, the Fischbach flows from the right at km 26.57.

Eschbach and Fischbach

The most productive source is that of the Eschbach and the Glasbach, which combine with other waters to form the Fischbach .

The Eschbach is reached at km 1.85 from the 3.5 km long Birkenmoosgraben, in the locality Eschbronn - Mariazell . At km 4.7 it connects with the Reutenbach coming from the right to the Hinterbach, this at km 5.46 with the Mittelbach to the Eschbach . At km 7.46 this meets the Glasbach coming from the right in Fischbach . The river section begins as a Fischbach . At km 11.76 after the source of the Eschbach, this Fischbach flows together with the Baden Eschach . Since this is the weaker partner and, at 13.9 km, also somewhat shorter than the main line, which has been 16.8 km up to this point, the name Fischbach is retained until the confluence with the Württembergische Eschach in Horgen.

On the slope of the valley north of the Fischbach there are the ruins of a Roman estate and a Roman bath.


After the confluence of Eschach and Fischbach, according to an older version of Württembergischer and Badischer Eschach, the now stately little river flows through a partially narrow valley with shell limestone rock walls on the steep slopes, a popular hiking area.

In Rottweil - Bühlingen the Eschach the Neckar united. The confluence transforms the Neckar from a brook into a small river. At this point the course of the Eschach is almost twice as long as that of the Neckar, and its catchment area, as well as its water flow, are about three times as large. Nevertheless, the Neckar, which maintains its direction of flow, is the main river. However, the Glasbach ( GlasbachFischbachBadische EschachEschach ), which rises on the Brogen, can be considered the main hydrological source load of the Neckar system .

Once the Eschach flowed beyond its current mouth further to the southeast. This river, called Ureschach , flowed into what was then the Aare-Danube near today's Tuttlingen .

natural reserve

Both the Badische and Württembergische Eschach as well as the lower reaches of Teufenbach and Fischbach are part of the FFH area Baar, Eschach and Southeast Black Forest . They are home to populations of the FFH species bullhead , brook lamprey , brook mussel , stone crab and beaver and are in parts protected as “flowing waters with flooding aquatic vegetation”. The tall herbaceous vegetation and riparian forest strips that can be found over long stretches along the banks are also protected as FFH habitat types . There are also numerous other habitat types on the adjacent floodplain and valley slopes.
