The Schmiedesbach is a left tributary of the Emscher in Herne with a catchment area of 4.665 km². It has an above-ground flow length of 2.2 km.
The stream is channeled and piped. It serves as a receiving water for the wastewater and pure water flows in the central part of the city of Herne. Above Holsterhauser Straße, it meanders, still very small, between footpaths and allotments northwest to the new housing estate Gartenstraße above the cemetery. Then it emerges again north of Rottbruchstrasse and south of the Cologne-Mindener railway line. After around 100 m, the stream is directed west, past the wholesale market area, the location of the former Julia colliery . To the west of the Essen-Recklinghausen railway line, the stream is directed in a narrow bend to the north and runs parallel to the railway line. To the south of the development on Cranger Strasse, the stream runs in a west-northwest direction. North of the A 42 , the stream flows northwest of the Emscher to parallel to Rottstrasse and Hertener Strasse. The stream forms the border between the Baukau and Crange districts . To the north of the substation of the Herne group power plant , the creek is passed under the Rhine-Herne Canal by means of a culvert , with a second canal being created for the creek to divert part of its volume at peak water levels. Shortly before it flows into the Emscher, the stream reaches the urban area of Herten .
At the end of the 1950s, large parts of the stream were still above ground. The source of the Schmiedesbach is now in an industrial area, the former site of the Hibernia nitrogen plant, later VEBA Chemie Werk II, then Hüls AG, south of Holsterhauser Strasse. In the middle of the 20th century, the stream came to the surface north of the factory premises and ran above ground along today's Bunsenstrasse to Grabenstrasse. In the Wanne-Eickeler urban area, the stream was led underground when new residential areas were opened up. Only at the historical border with Herne-Baukau did the water surface again.
As part of the conversion of the Emscher system , the conversion of the Schmiedesbach into an open clean water course is planned. Wastewater is then to be directed to the Bottrop sewage treatment plant via the Emscher Canal . The headwaters in the Hibernia industrial park are technically designed as an open system of forces . The further course of the stream is planned to be exposed by 2014.
A large part of the catchment area of the Schmiedesbach is in a polder location , so that drainage takes place via the Herne-Crange and Schmiedes Hof pumping stations . The affected sub-catchment areas are also to be drained in the free gradient in the future.
