The Schondelle is a 5.2 km long orographic left or southern tributary of the Emscher in North Rhine-Westphalia , Germany .

etymology

The name Schondelle is Low German . The name is made up of already = beautiful and dent = depression .

geography

The Schondelle rises in Wellinghofen in a spring pond at an altitude of 133  m above sea level. NN . From here it first flows in a westerly direction. At Lücklemberg the Olpkebach flows on the left . Below the mouth, the stream turns its course to the north, flows through the Zoological Garden and the Botanical Garden Rombergpark in Brünninghausen . The horse stream flows here on the right.

A little below, the Schondelle feeds a pond at the level of the Rombergpark gatehouse. For over a hundred years it disappeared here in a canal. The brook crossed the B 54 and the Phoenixpark underground , to then reach 84  m above sea level. NN to flow into the Emscher .

In the course of the renaturation of the Emscher by the Emschergenossenschaft , the city of Dortmund replaced the previous mixed water sewer system and separated the lower Schondelle stream from the dirty water by means of a complex decoupling measure. While a new sewer was created under the B 54 for the sewage in the underground tunnel, the river bed of the Schondelle was exposed or relocated to the surface. The new course, for which civil engineering work of up to 20 m height had to be carried out, which corresponds to approx. 200,000 t of excavated soil, follows the course of the B 54 from Rombergpark about 1200 m to the west to the allotment garden "Remy" and flows north of it into the Emscher . During the civil engineering work, historic wall remains of the Brünninghausen Castle were exposed in the planned stream bed . These were included in the redesign of the stream. The renovation work was completed in April 2014. The official breakthrough took place on April 17, 2014, with which the renatured Schondelle was opened to the public.

The Schondelle drains a 11.793 km² catchment area over the Emscher and Rhine to the North Sea . The creek overcomes a height difference of 49 m, which corresponds to a mean bed gradient of 9.4 ‰.
