Ever wonder where Bremen’s northernmost reaches begin? That’s where the story of the Blumenthaler Aue starts. It is a tale of water. It is a tale of land. It is a tale of Bremen’s ever-changing relationship with nature.
The Blumenthaler Aue is a small river. It stretches 12.7 kilometers. It eventually empties into the Weser River near Bremen-Blumenthal. Imagine its journey. The Blumenthaler Aue begins its life east of Schwanewede-Brundorf in Lower Saxony. From there, it meanders. It flows in a west-southwest direction. It picks up the Brundorfer Beeke and Eggestedter Beeke along the way. South of Schwanewede-Eggestedt, its course bends. It turns southwest. The Eckhofsgraben adds its water to the Aue. It then roughly traces the border between Lower Saxony and Bremen. Finally, it flows south. It makes its way through Bremen-Blumenthal. Near Burg Blomendal, the Beckedorfer Beeke joins the Aue. Then the Blumenthaler Aue empties into the Weser via a pumping station.
The Blumenthaler Aue’s watershed covers about 43 square kilometers. Most of it, 60%, lies in Lower Saxony. The remaining 40% is in Bremen. This area is vital. It provides drinking water. About 20% of the water comes from the river seeping into the ground. Since 1928, the Waterworks Blumenthal has centrally managed this process.
However, agriculture impacts the water quality. Studies by the Bremen Water Management Office in spring and autumn show this. The Blumenthaler Aue flows through mostly woods and grasslands.
Like many waterways in Germany, the Blumenthaler Aue was straightened in the mid-20th century. Parts of it were even channeled through pipes. But starting in the 1980s, things changed. Plans for renaturation began. These plans came to fruition in 2008. The state of Bremen, the Osterholz district, the European Union, and Lower Saxony funded these efforts.
Blumenthal itself is closely tied to the Weser River. Shipping has shaped its economy. Street names like Reepschlagerstrasse and Küferstrasse show this past. In the 19th century, the Weser was too shallow. Merchants had to transfer goods to smaller ships after Bremerhaven was founded. This created a lively barge traffic. Shipyards sprung up in Blumenthal. The population grew. The Bremer Wollkammerei woolen mill was founded in 1884. It brought even more people to the area. The need for better transport led to the Farge-Vegesack railway line in 1888. But after the Weser was corrected in 1895, barge traffic declined.
The Blumenthaler Aue’s story reflects Bremen’s story. It shows how industry and nature intertwine. It also highlights efforts to restore balance. As you stand here, consider the journey of this small river. Think about its impact. Think about the history it has witnessed. It’s a reminder that even small streams can have a big story to tell.
