geography

course

The Flehbach is formed from several source rivers mainly from the northwest slope of the Tütberg in the urban area of Bergisch Gladbach . The smallest source streams are nameless, the somewhat larger ones are called Wahlbach , Holzerbach and Kleiner Wahlbach . The Böttcherbach , which rises in the Moitzfeld area, joins from the north. Over a length of around 2 km, the Flehbach forms the city boundary between Bergisch Gladbach and Cologne . In Cologne-Merheim it flows together with the right Bruchbach , which was previously also known as Eggerbach and Frankenforstbach . The combined stream is called Faulbach , crosses under the Strunde and flows canalised into the Rhine.

Retention

After rainfall, the Flehbach absorbs large amounts of water. In the past it flooded Cologne-Rath , which lies on an old arm of the Rhine. The Flehbachdamm in the Königsforst regulates the runoff, as well as smaller overflow basins in the lower course.

River history

The Flehbach used to drive several water mills. Only the street name Flehbachmühlenweg in Lustheide reminds of the Flehbacher Mühle . The mill pond is still preserved from the oriel mill behind the Flehbachdamm.

Originally the brook flowed in Mülheim in the direction of Düsseldorfer Straße to Wiesdorf . Because of the floods, it was led directly to the Rhine through an artificial bed in Mülheim at the beginning of the 19th century. The name Bachstrasse is a reminder of this.
