geography

course

The Passbach rises about 750 m north of the outskirts of the Selmer district of Cappenberg at an altitude of about 102  m above sea level. NHN . From its source it first flows in a west-south-west direction and continues after an arc to the north-west until it reaches the edge of the settlement of the Selmer town center after about 6 km. there the smaller Herbach flows with it from the left , creating the Selmer Bach . This crosses the city center in a north-westerly direction, then flows further towards west-north-west and flows into the Lippe tributary Stever at about 45  m altitude west-southwest of the Selm district of Ternsche  - a few meters before it crosses under the Dortmund-Ems canal .

environment

The Passbach arises in the Kappenberg forest and flows through it initially in the Wolfsschlucht , later mainly through fields. The Selmer Bach is initially lined with urban development, after a piece in the hallway it runs through the northern Sandforter Forest. From its edge to the mouth there is another piece in the open hall.

Passbach and Selmer Bach still have a near-natural brook bed structure with a corresponding bank vegetation in some sections . Beech , alder and ash are the most common vegetation .
