The Laufbach is a body of water in the Baden-Württemberg district of Rastatt and in the Ortenau district . After a first west to north-west run in the northern Black Forest and then a northerly one in the Upper Rhine Plain, it flows 23 kilometers below its source at Rheinmünster from the left into the Sulzbach (the lower reaches of the Sasbach ). This runs, most recently as Mühlbach , over the Acher underflow Rhine side ditch for a long time parallel to the Rhine and then flows into it at Wintersdorf .

geography

The headwaters of the Laufbach are located near the Black Forest High Road ( B500 ) at Unterstmatt on the Muhrkopf and on the Hochkopf at an altitude of approx. 918  m above sea level. NN . Here it rises under the name Erzgrubenbächle , then another short piece of Stollenbächle , only to take its final name 2 km after its origin at the inlet of the left Dreibrunnenbächle and before the first settlement of Glashütte on its bank.

The Laufbach flows west-northwest through the Zinken Glashütte , where it is at an altitude of around 510  m above sea level. NN a small reservoir, the Laufbachsperre , crossed. The 6.4 meter high dam was built in 1923; the lake is used for energy generation and flood protection. The associated power plant is around 2.4 kilometers down the valley at an altitude of around 300  m above sea level. NN .

Later it crosses the place Lauf (Baden) on the lower Black Forest slope, whose name goes back to the Laufbach. In Lauf, the Lautenbächel also flows into the Laufbach, a first 3.5 km longer tributary from the southeast. After leaving Lauf, the stream runs to the northwest and flows past Ottersweier , where the Röderbach flows into it and shortly afterwards the Laufbach crosses under the Sasbach flood canal .

A two-kilometer section near Breithurst was classified as the only near-natural flowing water in the wide area in 1988 and has been part of the Waldhägenich nature reserve since 1989 . According to information from 2011, the Laufbach has also been straightened in this area; the cross sections and flow conditions are relatively uniform. However, the bank structures are close to nature. Other parts of the Laufbach are largely straightened; it now flows essentially north and finally flows east of Rheinmünster- Stollhofen into the Sulzbach canal, which is described in the following section.

Correction

In the course of the Acher-Rench correction , the Laufbach-Röderbach flood canal was built for the Laufbach and its tributary Röderbach . It branches off south of Otterbach from the Laufbach and unites with the Sasbach flood canal to form the Sasbach-Laufbach-Röderbach flood canal . This flood channel ends in the nature and landscape protection area Waldhägenich in the Hägenich flood retention basin . The retention basin drains into the Sulzbach . The small Sulzbächle flows towards the Sulzbach from the right ; later it also takes up the lower reaches of the Laufbach from the left.
