The five-kilometer-long Strothbach is an orographically left tributary of the Dalke in North Rhine-Westphalia in Germany .

River course

The Strothbach rises at a height of 131  m above sea level. NHN in the north of the Bielefeld district of Dalbke . The actual source is no longer performed open today because the water in the first meters of its flow path after the emergence of a new housing estate verdolt was. Therefore, the Strothbach emerges from a pipe on the northern edge of the newly created settlement and flows off in a south-westerly direction following the flattening of the Teutoburg Forest .

The Strothbach then leads north past the Dalbker industrial area and passes the almost 2.6 hectare Eichen-Buchenwald Strothbach nature reserve . This is a near-natural deciduous forest with mature wood, which was designated as a protected area in 1993 due to its importance for tree cavity-dwelling species.

Then the water first crosses under the federal motorway 33 , then crosses the city limits of Schloss Holte-Stukenbrock and from here runs through areas characterized by parkland . To the north of Sende, the Strothbach crosses the Bielefeld city limits again for a few meters and then enters the urban area of Verl . Not far from Verl's northernmost point, the stream finally flows into the Dalke on the left.

The water overcomes a height difference of 32 meters during its flow path, resulting in an average bed slope of 6.5 ‰.

Source exit at Dalbke

environment

During its course in Bielefeld's urban area, the Strothbach is assigned to water quality class II and is therefore considered to be "moderately polluted". From the point of transfer to the Gütersloh district , however, quality class II-III applies and thus a critical load.

etymology

The name "Stroth", which is often used in the region, refers to a formerly existing swampy valley, which was only drained during the course of human settlement and transformed into a grassland floodplain.
