The Weißach is a left tributary of the Murr in Baden- Württemberg. It Is formed from several streams in the eastern part of the Backnanger bay and runs entirely in the Rems -Murr -Kreis.

Name

The name " Weißach " is of Germanic origin, marking the waters as a stream of white, that is foaming water. It is first mentioned in a document of Bach 1027 Emperor Conrad II as " Wizzaha ".

In addition to the notation " Weißach ", which is used on official topographic maps, is also the spelling " Weissach " in use. The latter form appears in the names of places lying by the stream Unterweissach and upper Weissach, who are grouped together with other places in the community Weissach im Tal. The suffix " in the valley " refers to the term " Weissach Valley ", which is common for the entire catchment area of the stream with all the side valleys, among whose members also included the communities Allmersbach in the valley and floodplain forest.

Course

The Weißach flows composed of many small streams that originate in the eastern half of Backnanger bay on the edge of the Keuper escarpment. Is referred to as Weißach the creek from the upper Weissach place where the Glaitenbach, the Däfernbach and Brucher Bach come together. The Glaitenbach is 5.8 km in length, the longest source stream, which is 5.2 km Däfernbach little shorter, but together with his late bird feed stream the larger catchment area.

Between the villages of Upper Weissach Weissach and Aichholzhof the creek runs through the nature reserve at Seegut ( see below). In Aichholzhof he takes the water from the south of the Mühlbach and thereby changes its flow direction from west permanently to the northwest. Having Unterweissach flows through, the river runs a long time on the open field corridor, reaching the harder limestone floors and merges into a characteristic of this layer tortuous course. The Weißach passed the Backnanger district of Saxony hamlet. On the eastern outskirts of Backnang, in the former spinning Adolff (now the industrial park ), it opens around 7 km to Upper Weissach in the Murr.

Inflows

Origin of Weißach on the eastern edge of the upper Weissach from the confluence of the Glaitenbachs with the Däfernbach who has recently even added the bird creek.

• Right Quellast Glaitenbach, 5.779 km and 5.586 km ². Arises in a blade south of Sechselberg.
• Left Quellast Däfernbach, 5.15 km and 8.943 km ². Arises from east-southeast Däfern in a blade northwest of Althütte. Brucher Bach, from left, 3.774 km. A result of Kallenberg.

Mouth of the Weißach in the eastern Backnang through an industrial zone around the Eugen -Adolf -Straße. The creek is here from the source stream confluence 6.307 km, from the mündungsfernsten source of Glaitenbachs 12.086 km long and has an influence area of 52.713 km behind.

Catchment area

The catchment area of ​​Weißach lies in the eastern half of the Backnanger bay. It forms a distinctive, semi-circular umstandene from the mountains of the Swabian- Franconian Forest Talschüssel that is heavily dissected by the numerous small, incised streams. In the north there is the Murrhardter forest, east of the Welzheimer forest, and in the south there are the Berglen, on whose steep slopes flow the tributaries of the Weißach. The catchment area is about 50 square kilometers and ranges (clockwise) from the Brüdenbach in the north to Horbach in the southwest. The Brüdenbach which opens into Unterweissach is, with good 7.3 km also the longest tributary. Adjacent catchment areas of the Weißach are several other tributaries of Murr and Wieslauf in the southeast.

Current usage

Traffic

The Weissach valley, a bulge of the Neckar basin, located in the shadow of the bigger transport connection paths that run on the edge of the valley on Backnang. Only some county roads run through the area, in the valley of Weißach even between Unterweissach way up to Däfern (municipality riparian forest ).

Expansion of state

The Weißach is classified as waters along the entire length of the second order. According to the Water Act for Baden- Württemberg, this means that the river bed is public property of the respective communities, and that these are responsible for the maintenance of the water.

Individual sections of the tributaries are within the verdolt of them carrying places, such as the Glaitenbach in Lippoldsweiler and Allmersbach in the same place. The Weißach itself is led underground just before its mouth by the old mill site.

To cope with the flood protection, the three communities at the Weissach Valley founded in 2000, a common purpose association. In addition to designing an overall concept for the flood protection it is the duty of the Association to build a series of retention basins and operate, of which the majority are still in front of the establishment.

Conservation

The eastern and the northern edge of the valley Weissach belongs to the Swabian- Franconian Forest, and the slopes on the southern and eastern edge are found over a large area under conservation.

Between Upper Weissach and Aichholzhof the previously existing conservation area there was revalued in 1999 and declared a nature reserve. This NSG Seegut - Semmlersberg covers an area of 18.3 hectares on both sides of Weißach. In this area it is loud Conservation Ordinance to "one of the last major wetlands in the Rems -Murr-Kreis with riparian forest and reed beds " of high ecological importance. Also worth mentioning are several percussion slopes in limestone section in Saxony hamlet, which are considered areal natural monuments.

In 2004, the water of the water report Weißach and some tributaries was investigated. During the Däfernbach the place Däfern Class I -II ( " lightly loaded " ) could be certified and the group Bach ( in Cottenweiler ) and Brüdenbach ( in Unterweissach ) nor for Class II ( " moderately polluted " ) filed, had the Weißach itself the predicate " critically loaded " in Unterweissach ( class II -III) will be awarded, so it is one of the most polluted waters in the catchment area of ​​the Murr.
