The Rodenberger Aue is the 28 km long right tributary of the Westaue in Lower Saxony , in the districts of Hameln-Pyrmont , Schaumburg and the Hanover region , the border of which it forms in the lower reaches. It flows through the Deister-Süntel valley and the bordering landscape of the Bückeberg foreland below Rodenberg .


The Rodenberger Aue rises as a meadow near Kessiehausen, above Bakede am Süntel , approx. 190  m above sea level. NN . It drains the eastern Süntel, the western Deister and the northeastern part of the Bückeberg , a total of 170 square kilometers. In its course it absorbs the water of numerous low mountain streams, is dammed by weirs in Rodenberg , Horsten and Rehren , crosses the BAB 2 behind Lauenau , the B 65 near Bad Nenndorf , the Hanover – Minden railway line and the Mittelland Canal before Auhagen .

Between the Mittelland Canal and its mouth, the Rodenberger Aue has been extensively renatured since 1990 , as it is part of the Lower Saxony river protection system as one of the representatives of a typical Bördebach. Characteristic here are steep bank breaks, which can result in a breeding habitat for the kingfisher .

At Sachsenhagen -Auhagen it joins the Sachsenhäger Aue to form the Westaue , which soon afterwards flows into the Leine at Wunstorf -Liethe . The floodplain, which is rarely more than 2 meters wide, flows through the Deister-Süntel valley from southeast to northwest and thus follows one of the pre-glacial courses of the Weser , which today bends west in front of this valley.

In earlier times the floodplain was used to operate a few mills. Today it is occasionally used to train canoeists .

The floodplain takes in numerous low mountain streams from Deister, Süntel and Bückeberg:
