The Hörschbach is a 5 km long stream with its longer upper course Mähderbach in the Rems-Murr-Kreis in northeastern Baden-Württemberg , which flows into the Murr from the left and south in Murrhardt . The right source stream is called Langenwaldbach . The Hörschbach is well known for its two waterfalls , the upper rear and the lower front waterfall .

geography

course

The Hörschbach rises in the southern Murrhardt Forest and runs quite steadily in a northerly direction. It is fed by two brooks, of which the left Mähderbach is called and the right Langenwaldbach , at the very top perhaps also the Mähderbach ; both arise on the plateau of the Murrhardt Forest north and east of Sechselberg (municipality of Althütte ). Most of the water in the left brook consists of treated wastewater from the municipality of Sechselberg, as the brook serves as a receiving water for the sewage treatment plant. The streams flow on both sides of the Hörschhof in a northerly direction until, after about a kilometer at the edge of the forest, they begin to cut deeply into the plateau. The steep gradient at these points gave rise to the construction of two sawmills , the Rottmannsberger sawmill on the left and the Hörschhöfer sawmill on the right stream.

Within the next 600 meters, both streams lose 40 meters in height and merge at the rear waterfall. The left brook falls over a hard sandstone bank, initially three meters in free fall and then in cascades a further nine meters into the depth. Once at the bottom, it meets the right source stream, which falls over its own, smaller waterfall into the gorge. On the left Bach lies directly above the waterfall a reservoir can be emptied the (popularly called "Kläpple") with a small flap to at low water for a short time an impressive, by offset drop steps gischtreichen to observe waterfall.

The now united stream continues to flow in a northerly direction through a narrow gorge. On this two-kilometer section, he is accompanied by a narrow, unpaved path that can only be walked with sturdy shoes and sometimes also leads over stepping stones in the water. There are many hikers on this section of the stream, as it connects the rear with the front waterfall, which is at the lower end of the path. Here the Hörschbach falls over an erosion-resistant layer of the gypsum keuper 5 m in a hollow.

Less than a kilometer later, the Hörschbach leaves the forest and soon flows into the Murr coming from the east in the western settlement area of ​​the city of Murrhardt .

Catchment area

The dewatered Hörschbach an area of 8.8 square kilometers, which predominantly in murrhardt forest lies with the lowermost parts little upstream of the mouth in Bitzer , Geographically seen both subspaces of Schwäbisch-Fränkischen Waldberge . The highest point is above the Althüttener Gallenhof at about 567  m above sea level. NHN at a water reservoir on the northern slope of the Hohenstein , which is 572  m above sea level at the summit . Reached NHN .

The right watershed from here to the mouth separates initially from the upper source brooks of the Murr in the east, after the summit of the Hoblersberg ( 539.2  m above sea level ) then from the little upstream of the Hörschbach also in the settlement area of ​​Murrhardt into the upper Murr flowing Großkehbach . Along the left watershed from Hohenstein to the mouth of the river, first in the southwest the right upper course Glaitenbach of the large tributary Weißach of the middle Murr, then the deeper Weißach tributary Brüdenbach in the west, in the northwest the latter, the larger brook still from the left into the upper Murr Eschelbach flowing in , almost all via tributaries. Behind the northern border of the catchment area, on this side of the Hörschbach, only insignificant sloping streams run to the Murr.

geology

The source streams of the Hörschbach arise in the upper Mittelkeuper above the silica sandstone ( Hassberge formation ). Shortly before they unite, they fall over hard sandstone banks at the rear waterfall. Plenty of sintered lime has deposited on the steps . The front waterfall falls further downwards over an edge formed by the dolomitized and therefore more erosion-resistant Corbula Bank (former name "Engelhofer Platte") of the deeper gypsum keuper ( Grabfeld formation ). The gypsum keuper is also the deepest Triassic layer in the catchment area. The stream then flows into the upper Murr in the Quaternary strip of floodplain sediment deposited on both sides of the river.

natural reserve

The Hörschbach lies entirely in the Swabian-Franconian Forest Nature Park . The two headwaters are in addition in the conservation area murrhardt forest . The areas from the entry into the forest at the two sawmills to the exit from the forest at Murrhardt, which have been combined in the 46.4 hectare Hörschbachschlucht nature reserve since 1995, are particularly protected .

According to the ordinance, the purpose of the nature reserve is "to preserve the gorge with its natural geological outcrops and striking rock formations as a scientifically remarkable geological phenomenon" as well as the preservation of natural habitats in the Keuperklingen and its natural forest. In fact, according to various counts, between 130 and 250 plant species live in the gorge; the fauna is enriched by stone crabs , brown trout , fire salamanders and dippers .
