The Goldbach is a little over 3 km long brook in the municipal areas of Frankenhardt and finally also Stimpfach in the district of Schwäbisch Hall in northeastern Baden-Württemberg , which flows from the left into the upper Jagst after a very constant eastward run at the Stimpfach sewage treatment plant .

At the transition from the middle to the lower course in Dörzbach , the Jagst has another tributary, Goldbach , on the right .

geography

course

The Goldbach arises to the west below the Frankenhardt hamlet of Sandhof on the Bettlershalde, the small eastern slope of the Sandberg, a few meters below the road climbs of the K 2671 from Honhardt up to about 475  m above sea level. NHN . The headwaters are fallow, heavily interspersed with saber-growing trees; Above the road there is a heather-like area, as often occurs on the marly slopes in the area.

The unstable trickle here feeds a small swamp after a few meters and then apparently disappears in a drainage at the edge of a flatter meadow. The permanently open run to the east begins at the southeast edge of the meadow, accompanied by a gallery of trees and bushes, which then thin out. After about a kilometer from the source, the previously quite flat valley basin deepens more deeply, after passing the host field on the right bank, the Goldbach forest tongue reaches the bank from the right slope, at the border of the open corridor approaches it and flows into the Wirtsbach .

After the forest tongue and a piece of open corridor, the Rote Hölzlein begins on the right bank , from which the municipal boundary of Stimpfach moves from the right to the run. The only a few dozen meters long drain of a spring feeds the Goldbach from a small depression in the forest. After the riverside forest has been exposed, the bank itself remains tree-lined and the Goldbach passes under the B 290 Ellwangen - Crailsheim at the foot of the Stimpfach hamlet, Streitberg, on the edge of the Jagstaue . After a hundred and fifty meters over the floodplain, the Brunnenbächle , the largest tributary of over two kilometers in length, flows into the river immediately before crossing under the Upper Jagstbahn , which shortly before had passed through a dead water of the Jagst that was probably separated from the river when the railway was built. About a hundred meters after the railway, the Goldbach itself flows at about 408  m above sea level. NHN at the Stimpfach sewage treatment plant from left and east into the upper Jagst .

After its run of about 3.2 km in length, it flows about 67 meters below its origin, its mean bottom slope is about 21 ‰.

Catchment area

The Goldbach has a catchment area of ​​around 3.0 km² in size and roughly club-shaped. The pointed end lies in the west on the Sandberg near Sandhof, the blunt end at the mouth about 3.5 km east of it; across this axis it is a maximum of 1.4 km wide.

In terms of natural space, it is divided into a northern part with almost the entire course, which is part of the sub-area Burgberg-Vorhöhen and Speltachbucht , and a southern part, which is included in the sub-area Ellwanger Berge , both within the Swabian-Franconian forest mountains .

The natural boundary here follows roughly a geological one, because in the northern part there is reed sandstone ( Stuttgart formation ) and in the valley basin the underlying gypsum keuper ( grave field formation ), while on the southern and in front of the short western watershed the terrain over the lower colored marl ( Steigerwald Formation ) rises to a sandstone plateau ( Hassberge Formation ), as it is typical for the northern Ellwang Mountains. In the area of ​​the hamlet of Streitberg, the geological map shows Goldshöfer sands which , judging by the terrain profile, were probably also temporarily dismantled. Due to its comparatively low altitude, however, it should not be about old deposits of the Urbrenz running to the Danube, but rather newer redistribution layers from those after the reversal of the direction of the upper Jagst towards the Neckar and Rhine.

The Goldbach catchment area in turn borders in the northwest with the watershed of the Steinbach , which flows further down into the Jagst, in the north-west, with the watershed soon becoming less prominent . In the north, the smaller and closer Klingenbach also competes with this. Even before the step to the higher Mittelkeuperschichten, the drainage area of ​​the small Gehräckergraben forces itself in the southeast in front of that of the Sulzbach and its tributaries, which on the other side of the most prominent watershed on the ridge from Eckarrot to Sandhof in the rest of the south also drains to the other side to the Jagst leads.

There are no settlements on the banks of the Goldbach and apart from the two traffic routes in front of the mouth, only dirt roads cross it. In the catchment area there are some houses of the hamlet Sandhof in the far west on the Sandberg , in the far south half of the hamlet Eckarrot on the southern watershed, both belong to the municipality of Frankenhardt , as well as the hamlet of Streitberg between Goldbach and the inflowing Brunnenbächle, a district of the other municipality of Stimpfach , which compared to Frankenhardt has the smaller area share in the area.

Tributaries and lakes

Origin of the Goldbach a little above a small swamp on the Bettlershalde , the eastern slope of the Sandberg ( 503  m above sea level ), at about 475  m above sea level. NHN a little below the pavement of the K 2671 Honhardt - Sandhof . Almost from the start, the Goldbach flows almost exactly to the east.

  • Wirtsbach , from the right and south to about 425  m above sea level. NHN southwest of Appensee on the northern edge of the Goldbach forest , 0.6 km and approx. 0.4 km². Arises at about 442  m above sea level. NHN a little north-below the water reservoir at Eckarrot in the forest Kesselwasen .
  • (Source discharge), from the right and south-southeast to about 418  m above sea level. NHN northwest of Streitberg, under 0.1 km and approx. 0.1 km². Arises at about 425  m above sea level. NHN in a forest trough on its steep slope.
  • Brunnenbächle , from the right and south-west to just under 410  m above sea level. NHN immediately before crossing under the Upper Jagstbahn , 2.2 km and approx. 1.0 km². Arises at about 459  m above sea level. NHN in a meadow basin between Eckarrot and the water tank. The Brunnenbächle initially flows east, then roughly north-northeast.
    • RiverIcon-SmallLake.svgFlows through shortly before the mouth at just under 410  m above sea level. NHN a loop of the Jagst, 0.2 ha, which was apparently cut off during the construction of the railway.

Mouth of the Goldbach from the left and west to about 408  m above sea level. NHN at the sewage treatment plant from Stimpfach in the upper Jagst . The Goldbach is 3.2 km long and has a catchment area of ​​approx. 3.0 km².

Nature and protected areas

From the beginning of the permanently open run, the Goldbach is accompanied by a short strip of alluvial forest. After that, the often completely bare course through meadows only becomes closer to nature again at the Goldbach forest tongue, which reaches it from the right , here is a swamp sedge reed on the bank. From the Roten Hölzlein it flows close to nature, swinging next to a strip of alluvial forest, to the left of this is a litter meadow that is protected as a natural monument . The section between the main road and the railway line forms a contiguous floodplain forest with the mouth of the Brunnenbach and the Jagst Altarm, which is also a natural monument. The Jagstaue belongs to the landscape protection area Jagsttal with adjacent areas between the district border against the Ostalbkreis and the bridge of the federal highway 290 over the Jagst at the Wiesmühle .
