The Otterbach is only 2 km long, with each of its two upper courses together between 6 and 7 km long creek in the Ludwigsburg district in central Baden-Württemberg , which flows into the lower Murr from the right and northeast just before Steinheim an der Murr .

The Murr has yet another tributary Otterbach at its upper knee before Murrhardt .

geography

course

The Otterbach flows near the hamlet of Vorderbirkenhof in the small town of Steinheim an der Murr at around 247  m above sea level. NHN from its two upper reaches Rohrbach (from the north-northeast) and Kaisersbach (from the east-northeast) together, both of which arise in the large mountain forest area Hardtwald and both are significantly longer than the Otterbach itself. This flows consistently southwest through a rapidly deepening Kerbtal, its slopes are initially still open in the Steinheim hamlet Lehrhof on the left edge. A little further down there is forest, between which the Otterbach runs in a narrow meadow. The only settlement in the valley is a single house on the deep downward Talsporn Burgberg at the transition from the brook to the Murrtal. There the brook crosses the state road L 1126 running on the right edge of the meadow. After less than a hundred meters over the Murr-Aue, the Otterbach flows out at a little over 198  m above sea level. NHN about half a kilometer above the Steinheim local border from the right into the lower Murr .

The Otterbach falls on its 2.0 km long path by almost 49 meters, it has a mean bed gradient of 24 ‰. Together with its longer, at about 354  m above sea level. The right upper reaches Rohrbach, which rises from the NHN, is 6.6 km long and falls on this route by 156 meters in altitude and has the same base gradient.

Catchment area

The Otterbach has a 9.0 km² large catchment area, which in natural spatial vision about half and with its top share in the Hardtwald the subspace mountains Southwest Löwensteiner the Swabian-Franconian Forest mountains belongs with the other predominantly outside the subspace Backnanger bay of the Neckar basin and the smallest part, including the entire Otterbach course, is the sub-area of ​​the Inner Backnang Bay of the Neckar Bay. The 392.9  m above sea level. NHN's highest point is the summit of the Grießberg on its northeast side.

Beyond this watershed through the Hardtwald lies the catchment area of ​​the Wüstenbach , which flows significantly further up into the Murr and which competes here via the tributary Krummenbach of its right main course upper course Rohrbach , in turn further east-northeast via the Kammerfeldgraben to Rohrbach and in the east via the directly into the Wüstenbach flowing into the Diebsbrunnenbach . The Eichbach runs behind the southeastern border, the Rielingshausen Weidenbach for only a short section and then the Sulzbach zur Murr, which also rises there, for a long time , the Sulzbach being its last tributary before the Otterbach.

The outflow on the entire western and northern side of the Otterbach catchment area, apart from a short tributary near the mouth of the Murr, takes up almost all of the Bottwar , here it competes over some all short tributaries from the left, including the Wehrbach and at the top the north side of the Hardtwald the Lembach .

There is no settlement directly on the banks of the Otterbach. In the catchment area, the hamlet Lehrhof with a nearby Aussiedlerhof group in the Bäumlesäckern are on the upper left slope of the Otterbachtal, the hamlet Vorderbirkenhof in the triangle near the confluence of the two upper courses , the hamlet Forsthof on the western watershed of the Rohrbach and the hamlet Hinterbirkenhof set back on the spur between the upper reaches of Rohrbach and Kaisersbach. Hinterbirkenhof is located in the Rielingshausen district enclave of the small town of Marbach am Neckar , the rest in the area of ​​the small town of Steinheim an der Murr .

Above all, the upper catchment area in the Hardtwald is fragmented by the municipality. By far the largest part is held by the town of Steinheim, including the central portion of the Hardtwald and the entire course of the Otterbach in the foreland. In addition, part of the small town Großbottwar parts on the northwestern edge of the municipality Murr a piece of Rohrbach-sub-basin, the municipality Erdmannhausen a water body loose fragments of his Waldexklave on the eastern edge of Pleidelsheim also a piece of his Waldexklave closer to the center of the forest and only small proportion of forest and the industrial area around the Hinterbirkenhof to the district enclave Rielingshausen of Marbach. All of these communities belong to the Ludwigsburg district . A waterless edge snippet in the north lies in the Kleinaspach district of the municipality of Aspach , which is the only one in the Rems-Murr district .

geology

The Otterbachs itself runs in the Upper Muschelkalk almost from the beginning , on the last half kilometer in its trochitic limestone formation . On the higher slopes above, the Lettenkeuper ( Erfurt Formation ) of the Unterkeuper stretches out where it is not covered by loess sediment from Quaternary deposits , as on the plain above . To the left of the upper shell limestone valley around the teaching yard there is even a small Gipskeuper island ( grave field formation ).

Most of the upper catchment area around the two headwaters lies in the Gipskeuper. Occasionally mountains rise without recognizable reed sandstone ( Stuttgart Formation ) in between, over the Untere Bunten Marl ( Steigerwald Formation ) to the Kieselsandstein ( Hassberge Formation ), in Ochsenhau and the Grießberg in the Rohrbach area and the Bülzberg above the zum Kaisersbach running Gäfenklinge; the ceiling of the Kaisersberg on the side of the central Kaisersbach itself, however, consists only of lower colored marl. In the smaller non-forested areas of these sub-catchment areas there is often loess sediment or loess-bearing floating earth .

Nature and protected areas

Natural monuments are a sinkhole field in the Gipskeuper in the killer pit with a large sinkhole directly above the Grießberger Weiher and two other sinkholes on the western edge of the Rohrbach catchment area as well as a wetland in the Rohrbach valley and the dry slope Sommerrain in the Otterbach valley opposite the teaching farm.

The Hardtwald around the two upper courses lies in the " Hardtwald, Kaisersbachtal, Rohrbachtal, Benning and Harzberg as well as Bottwartal between Großbottwar and Kleinbottwar with adjacent areas " called the landscape protection area , the Otterbachtal itself is part of the landscape protection area Unteres Murrtal . A water protection area Rohrbachbrunnen lies around the lower Rohrbach. The courses of the Otterbach and its tributaries are mostly very close to nature.
