The Blumenthaler Aue is a right 12.7 km long tributary of the Weser , which flows into Bremen- Blumenthal .
Course, catchment area
It rises in Lower Saxony east of Schwanewede - Brundorf , flows from there towards the west- south- west and takes on the Brundorfer Beeke and the Eggestedter Beeke from the right , changes its course south of Schwanewede- Eggestedt , takes the water of the Eckhofsgraben from the right and then runs approximately along the border between Lower Saxony and Bremen to the south. It then continues south through the Bremen- Blumenthal area , taking in the Beckedorfer Beeke from the left at Blomendal Castle and finally flowing into the Weser via a pumping station .
The water catchment area of the Blumenthaler Aue is around 43 km². The largest part is 60% in Lower Saxony. 40% are in Bremen.
Water management
The water catchment area of the Blumenthaler Aue also serves to produce drinking water, with around 20% of the water obtained coming from seepage in the area of the flowing water. Since 1928, drinking water has been supplied centrally by the Blumenthal waterworks .
The widespread agricultural use in the catchment area has an impact on the water quality, which was demonstrated in spring and autumn in particular by studies by the Bremen Water Management Office .
ecology
There are mainly forest and green areas along the banks of the Blumenthaler Aue.
Like many bodies of water in Germany, the Blumenthaler Aue was straightened in the middle of the 20th century and partly routed through a pipe system. Restoration measures were planned from the 1980s and were completed in 2008. These measures were financed by the state of Bremen, the district of Osterholz as well as by the European Union and the state of Lower Saxony.
