The Warmenau on the border near Wallenbrück

The Warmenau is an 18.5 km long, southern and right tributary of the Else . It rises in Werther in North Rhine-Westphalia , flows largely on the borders of the Westphalian districts of Gütersloh and Herford to the Lower Saxony district of Osnabrück and flows on the border from Melle (Lower Saxony) to Bünde (Westphalia).

geography

course

The Warmenau rises in the Westphalian district of Gütersloh on the northeastern roof of the Teutoburg Forest. Its source is in the north of the city of Werther at about 122  m above sea level. NHN between Gerhart-Hauptmann- Strasse in the west, which is located in a residential area, and Esch Strasse in the east, which runs through an industrial park . The Schwarzbach rises 2.3 km southwest of the Warmenau spring south of the Werther town center .

Initially, the Warmenau flows north between the rural Werther districts of Häger in the east and Rotenhagen in the west. When the Vossheide trench flows into it , it reaches the border with Lower Saxony, on which it lies between Hengstenberg , located in the Westphalian district of Herford , a locality of the district of Bardüttingdorf belonging to the city of Spenge , and Neuenkirchen , a district of the Lower Saxony district of Osnabrück City of Melle , which runs in the northwest.

After the Warmenau has flowed for around 400 m only on the Westphalian side before Hengstenberg, it passes the Königsbrück Castle ( 86.1  m ), which is located on the Lower Saxony side, a little before the confluence of the Wißmannsbach at Bach river kilometer  11.4 , from where it follows Northeast pans. After then flowing into the Hobebach (Lower Saxony) and passing the opposite Heinrichsee ( 79.5  m ), it flows between the Spenger district of Wallenbrück in the east-southeast and Schiplage-St. Annen , a district of Neuenkirchen in the west-north-west. Shortly afterwards, the Warmenau passes the Warmenau estate ( 76.5  m ) located on the Lower Saxony side at the river kilometer 7.5 and feeds its moat; here the Warmenau passes under a house on the national border.

After the confluence of the Lower Saxon Krumkebach stream , the Warmenau runs entirely in Lower Saxony for about 350 m and then flows back to the state border. Then it takes up between the Spenger district Nordspenge in the south-southeast and Hoyel , a locality of the Meller district Riemsloh , in the north-northwest the Spenger Mühlenbach and the Eselbach . Then the Warmenau passes the Martmühle ( 74  m ) and the settlement of Balgerbrück ( 72  m ), both of which are located in the Mell area. It then flows between Klein-Aschen , a locality of the Spenger district of Hücker-Aschen , and the Meller district of Groß Aschen in the west, only to run again shortly afterwards along a 1 km stretch in Lower Saxony.

Then the Warmenau flows at about 65  m altitude into the Werre tributary Else coming from the west and flowing there on the national border  - at the Else river kilometer  15.3). Opposite its mouth is the Ahle district of the city of Bünde in the Westphalian district of Herford .

Nature reserves

The Warmenau flows through or grazes two nature reserves (viewed downstream):

  • The Turenbusch nature reserve ( CDDA no. 165975) is located in the urban area of ​​Spenge - immediately east of the border with Lower Saxony. It has been designated since 1989 and covers 29.05  hectares . The valley of the Warmenau is here at Bardüttingdorf as a typical Siek for the Ravensberger Land . In addition to alluvial forests ( alder forest ), wetlands and green meadows, the Siek includes several other flowing and still waters as well as beech forests on the valley slopes . The smaller rivers that flow into it run in natural notch valleys that have not been transformed into the Siek. The European tree frog is the only place in the Herford district in the nature reserve .
  • The nature reserve Warmenau (CDDA No. 166170; HF-014) is 27.02 hectares and is also located in the Spenger urban area - immediately southeast of the border with Lower Saxony. It has been designated since July 1, 1989 and consists of two spatially separated and closely successive partial areas; Martmühle and Strangfeld. It is a natural floodplain in the valley of the meandering Warmenau, which is cut about 2 m deep into the landscape. There is a small body of still water in the wet grassland along the stream.

history

The Warmenau marked the border between France and the Kingdom of Westphalia between 1807 and 1811 and was the state border between the Kingdom of Hanover and the Prince Diocese of Osnabrück and Prussia for a long time before and after .
