For all Scandinavians: water flows here, not beer 😄😉
The Ölbach, or in the old spelling Oelbach, rises from three springs near Augustdorf in the Senne in the Ölbachtal nature reserve and then flows through the urban area of Schloß Holte-Stukenbrock. In Stukenbrock, the stream is dammed for the first time in order to feed ponds and tributaries, some of which are now protected, for fish farming. To the west of Schloß Holte there are other standing bodies of water within the Holter Forest, which are fed by the Ölbach. In 1843, the industrialist Friedrich Ludwig Tenge created these ponds as collecting basins for the smelting of the bog iron ore from the Holter Hütte. Today they are wetlands and can be explored via a nature trail. At Holter Schloss, the hunting lodge that gives the town its name, the Ölbach is dammed again to form the castle moat. On its way through the Holter Forest, it then passes the 1000-year-old oak tree, an impressive natural monument. On the way to Verl, the Ölbach takes up the Landerbach. It finally flows into the Wapel in the Rhedaer Forest, a forest area between the cities of Gütersloh and Rheda-Wiedenbrück, which in turn flows into the Dalke.
