The Haarbach is a right-hand brook in the Wurm - Rur - Maas river system in the city of Aachen in the North Rhine-Westphalian city ​​region of Aachen in the administrative district of Cologne .

history

The Haarbach is a centuries-flowing waters , which even today for field drainage in the Aachen basin is needed. With the settlement of the rivers and streams , the people of the Haarbach increasingly used water power to operate water mills in suitable locations through damming and natural slopes . Several buildings and the Welsche Mühle still provide evidence of this era in the Aachen area.

After repeated floods in the center of Aachen- Haaren , where the Haarbach flows into the Wurm, a rain retention basin was built below the Kahlgrachtmühle in the early 1970s and the flow was limited.

Bach description

In earlier times the sources of the Haarbach were at a height of approx. 231 m above sea ​​level near the former Driescher Hof in the Aachen- Forst district . Today the brook begins near Gut Neuenhof. The stream with an original length of almost 9 km is a tributary of the Wurm and flows northeast in the direction of Eilendorf , passing under the Aachen- Eschweiler railway line at the Nirm district . The further path of the creek runs in a north-westerly direction, south past Verlautenheide and then bends to the south-west and flows through the retention basin and the Haarbachtal. In this flatter area shortly before the development line of Haaren, the stream was originally able to meander freely . In 1987, excessive safety measures for a power pole, a bridge foundation and a hiking trail resulted in the stream continuing to follow several meander arcs, but these are now fixed with large stones and many specially planted trees. In the city center of Haaren, the Haarbach is largely canalized. On the Tuchmacherweg, the Haarbach flows into the Wurm as an open stream at a height of about 144 m above sea level. The water association Eifel-Rur (WVER) is responsible for the care and maintenance of the water .

Renaturation

In large parts of its course, the Haarbach flows through an artificial stream bed. These sometimes unsightly and unnatural concrete profiles are now being dismantled by the water association in some places in order to restore the stream bed to a condition that is as natural as possible and to upgrade it ecologically. In 2015, a 380 m long straightened section of the stream was rebuilt at great expense in Eilendorf above the Kahlgracht mill. The new, strongly curved route extended the Haarbach here by 190 m. In 2016, in the area of ​​Nirmer Platz in Eilendorf, the green area through which the Haarbach flows will be chamfered and a floodplain will be created.
