Dadau

The Dadau is a left tributary of the river Hunte. For most of its upper course it forms the boundary between the districts of Diepholz and Vechta and for a shorter distance along its lower reaches it forms the boundary between the town of Diepholz and the collective municipality of Barnstorf.

The 18.9-kilometre-long Dadau has its source in the Diepholz Moor Depression in the Südlohn Moor near the town of Lohne. Then it flows northwards between the Südlohn and Brägel Moors to the west and the Aschen Moor to the east and then turns to head east at the boundary between Lohne and Vechta on its left bank. Beyond the B 69 federal road, the Dadau flows in an easterly, and sometimes south-easterly, direction. In its final section it runs through the municipal area of Drebber. The Dadau joins the Hunte a few metres east of the B 51 in Cornau, a part of Drebber. The Hunte carries on flowing northwards towards Oldenburg. Between the Hunte and the Dadau is Deckau, also a part of Drebber.
