The Goldbach is a little more than 5 km long stream in northern Baden-Württemberg , which flows into the short mill canal of the oil mill next to the Jagst from the right and northeast in Dörzbach in the Hohenlohe district .

The Jagst previously had another tributary, Goldbach , on the left at the upper reaches near Stimpfach .

geography

course

The Goldbach arises in a field next to the federal road 19 between the villages of Stuppach and Rengershausen in the picture fields between the woods of Heiligenholz in the northwest and Salztröge in the southeast at about 377  m above sea level. NHN . From here on, like its upper tributaries, the inconsistently water-bearing brook flows southwest over the longer part of its course. After less than 300 meters, he changes under the main road that follows him in the valley to the mouth, to the right-hand side and from here mostly runs next to meadows. After about 800 meters, an accompanying wood sets in on the bank.

After about a third of the run, it enters Rengershausen, which stretches along the stream and the main road. Towards the end of the village, the 0.6 km long, now stable Uhlbach flows from the southeast , which a little earlier in the village had taken up the very short Kirchlesbrunnen ditch . Below the town limit, a mill channel that used to be about 0.7 km long opens out from the right at an old mill, which descended approximately opposite the inlet of the Uhlbach and is only partially preserved.

Less than 400 meters below the mill, it crosses the district boundary to the area of ​​the municipality of Dörzbach and now runs ever more southerly in a valley deepened over 80 meters between the wooded slopes of Büttelsberg on the left and Oberes Holz on the right. Below the tree line on the right on the open lower slope are two small nature reserves. After the last strongly meandering course, it enters the soft area of ​​Dörzbach.

In this village the Goldbach flows from the right and finally north to just under 235.8  m above sea level. NHN near the house at Klepsauer Straße No. 11 in the mill canal of the oil mill running to the right of the Jagst , which runs a quarter of a kilometer down into the river. The 5.4 km long Goldbach has a total gradient of around 141 meters in altitude and thus a mean bed gradient of around 26 ‰.

Catchment area

The Goldbach drains an area of 7.6 km², most of the subspace Middle Kocher-Jagst levels of the natural environment Kocher-Jagst levels belongs, with a very small estuary near part also the subspace Lower Jagsttal .

There are layers of shell limestone in almost the entire catchment area . The Goldbach rises in the Upper Muschelkalk , reaches the Middle and in Rengershausen the Lower Muschelkalk at approximately the inlet of the brook from the Wolfsäcker , from which it crosses into the band of Quaternary flood sediment that accompanies the river at the entrance to the Jagst floodplain in Dörzbach . On the top of the Stocker picture above the shell limestone there is still an island of Lettenkeuper ( Erfurt Formation ), the highest layer of Triassic deposits.

There is also the 431.4  m above sea level. NHN highest point of the catchment area at its northeast corner. In the course of from there southwest pulling the mouth left-watershed catchment area of the beyond only Steinbach of about at, Rißbach dewatered in the upward Jagst nearer the one at the mouth then the opening out shortly before the Dörzbach in the Jagst gravel trench . Behind almost the entire right-hand watershed in the northwest from the mouth upwards, the Laibach runs to the Jagst, a little below the Goldbach near Klepsau . The hydrologically most important watershed, however, runs in the north of the catchment area in front of an inconsistent upper course ditch to an often dry upper course of the noticeably more important Erlenbach , which also flows much further down into the Jagst.

In its predominantly open part, the catchment area is almost completely under plow, while the forest in it is limited to the ridge layers, but on the lower reaches also occupies the middle to lower slopes. Its larger upper part belongs to the town of Bad Mergentheim in the Main-Tauber district , there is only the village of Rengershausen on the Mittellauf, which will soon be followed by an old mill outside the village; the lower one lies in the area of ​​the municipality of Dörzbach in the Hohenlohe district , a small part of the eponymous village lies in the corner of the mouth. There are no other settlement areas in the catchment area.

Origin of the Goldbach at about 377  m above sea level. NHN in a field next to the B 19 between the Bad Mergentheimer villages of Stuppach and (closer) Rengershausen .

  • (Bach from the Wolfsackern ), from the left and east to about 342  m above sea level. NHN a little above the forest island Teufelshecke on the opposite slope, 0.8 km and approx. 0.5 km². Arises at about 360  m above sea level. NHN on a field path star between the forests of Buchholz and Salztröge . Digging away.
  • (Stream of the Four Gardens ), from the right and north-northwest to about 321  m above sea level. NHN opposite the confluence of the K 2845 into the B 19, 0.5 km and approx. 0.3 km². Arises at about 360  m above sea level. NHN between the tubs of four gardens and fields . Digging away almost everywhere.
  • (Inflow from the Jörgengründle ), from the left and east to about 318  m above sea level. NHN little after the previous one. Has an open course only about 0.1 km long, accompanied by wood, above it dry, and a catchment area of ​​about 0.8 km². Arises in the open at about 321  m above sea level. NHN only in the Goldbach-Aue. The K 2845 B 19 coming from Hachtel runs through the Jörgengründle up to the B 19 in the Goldbachtal.

Mouth of the Goldbach from the right and finally north to almost 235.8  m above sea level. NHN in Dörzbach near the house at Klepsauer Strasse no. 11. The stream, including its rather inconsistent overflow, is 5.4 km long and has a catchment area of ​​7.6 km².

Nature and protected areas

A large part of the right slope of the valley near Rengershausen belongs to the Bad Mergentheim landscape protection area , followed by the larger part of the lower catchment area on the district boundary down to the local boundary of Dörzbach to the Jagsttal landscape protection area with side valleys and adjacent areas between the Schwäbisch Hall district boundary and the Krautheim / Schöntal community boundary .

At the open lower right slope of Goldbachstals are shortly after the transfer to the municipality of Dörzbach and in Hohenlohekreis two under conservation related areas, namely the 3.4-hectare nature reserve sign and immediately followed by the 3.3-hectare nature reserve slope at Rengerstal . Both are extensively used, heather-like open areas on limestone grasslands with more or less interspersed bushes and individual trees that carry a warmth-loving plant population , as is more common in the north in the Tauberland , but noticeably rarer here near the hunting ground. In some cases, evidence of earlier use for viticulture is required, but stone bars are no or nonexistent. Shortly after Rengertshausen, the FFH area Jagsttal Dörzbach-Krautheim begins .

The 0.2 hectare wetland natural monument in the forest area Königseiche Stöckerbild surrounds the small pond mentioned in a bowl doline to the upper catchment area of ​​the tributary from the Jörgengrund . On the right-hand spur of the Eisenhut valley mouth above Dörzbach, orchids grow on around 0.2 hectares of open land, which is also protected as a natural monument.

Below the small pond in the horse mackerel picture there on the forest slope above the Jörg basic two small wetlands in the region of a further shallow sinkhole. The Goldbach itself is from a little before Rengertshausen to the mouth, with the exception of the running parts in Rengershausen, where it also flows underground for a long time, as well as in Dörzbach, where it mostly runs open, a very natural, for this limestone region, a stream of varying widths from one to one four meters, which is often dry in the upper area. It falls over small banks, showing partly sandy sediment in the rocky bed elsewhere. Lime sinter has grown from small falls on the lower course . It is accompanied by a narrow strip of alluvial forest with ash, alder and other types of wood. On the widely open right-hand slope around Rengershausen there are several woods, some of which stand on old stone bars. Shortly before the mouth of the valley to the Jagsttal, there are further areas of grassland on the slopes in addition to the two nature reserves already mentioned.
