The source region of the Mehner Bach consists of two stream runs and lies in the
Wiehen Hills. The eastern headstream rises not far from the summit of the
Kahle Wart near the boundary with the parish of Hüllhorst, the western one in an area that is known as
Gerliethe. Both headstreams merge 300 metres south of the village of
Obermehnen. The Mehner Bach then flows generally north-northwest through the
Lübbecke Loessland, through the two villages of
Obermehnen and Untermehnen, then through
Blasheim and Eikel and finally through the
Hollwinkel Wood. As it enters the aforementioned wooded area the stream leaves the territory of Lübbecke and flows for around 700 metres on the land of the borough of Preußisch Oldendorf, before emptying into the
Große Aue not far from the village of
Hedem. Just southwest of the Hollwinkel Wood the stream forms the boundary between the boroughs ofLübbecke and Preußisch Oldendorf for around 50 metres. Its catchment area also includes a small part of the parish Hüllhorst because, in the source region, the boundary between the commune of Hüllhorst and the territory of Lübbecke lies somewhat north of the watershed. The source of the Mehner Bach is located only around 300 metres from the source of the
Rehmerloh-Mennighüffer Mühlenbach on the opposite side of the hill crest. == References ==
