The Gervershagener Bach is a 2.8 km long left tributary of the Wupper , which is called Wipper here in the upper reaches. The brook rises at 434 m altitude in the Gervershagen forest east of the Marienheider district of Gervershagen on the L306 state road, is dammed in ponds near the source and flows in a westerly direction past Gervershagen. Two other larger ponds dam the stream behind the village. At the dam of the second pond, the brook on the right-hand side receives an inflow from a nameless body of water, and shortly thereafter also from the right-hand side of the Gerverssiefen . A nameless brook and the Frohnensiefen are the next orographically right tributaries.

The middle course now flows into the Brucher Dam , in which it unites with the much shorter Brucher Bach . The Wipper overpass , the Brambuscher Bach , the Steinkuhler Siefen , the Röttger Siefen and an unnamed inlet on the left carry more water into the dam . According to the river basin geographic information system of the competent Wupper Association and the waters Directory NRW is the outflow of Brucher Dam, contrary to the usual convention not Brucher Bach but Gervershagener Bach. Therefore the Gervershagener and not the Brucher Bach is officially a second order body of water in the river system of the Wupper, the Brucher Bach consequently a tributary of the Gervershagener Bach despite its quality as namesake of the common dam.

The outflow takes the Bocksiepen and a parallel branch of the Wipper from the right below the dam wall and crosses under the Hagen – Dieringhausen railway line . Behind the railway line, the Gervershagener Bach feeds part of its water into a water ditch that is dammed orthogonally to the main direction of flow, the drainage of which flows into the Neuenhauser Siefen at Neuenhaus . Behind the water entry into the ditch, the Gervershagener Bach flows into the Wupper at an altitude of 357 m in the 21-hectare nature reserve Wipperaue Eulenbecke (identification: GM-077, CDDA code: 344819).
