Deister-Süntel Valley

The Deister-Süntel valley is located in the north-east of the Weserbergland in Lower Saxony between the Bückeberg-Süntel and Deister mountain ranges in the Schaumburg and Hameln-Pyrmont districts.Contrary to what you would expect from looking at the map, the Deister-Süntel valley extends northwards beyond the Süntel area into the Rodenberger Mulde east of the Bückeberg and the Auetal and south to the Hachmühler basin with the Kleinen Deister in the east and thus reaches a length of around 25 km.At the watershed of the valley north of Bad Münder, two rivers have their source at the Süntel. The Hamel has its source in Hamelspringe and flows south into the Weser. The Rodenberger Aue rises in Bakede and flows north into the Westaue, which in turn flows into the Leine. They are fed by around 20 streams from the Deister and Süntel.
