Source flows and name transfers
The historical source of the Angerbach was in Velbert in a spring valley called “In den Fliethen” near the Kotten “Oberste Flieth”, the headquarters of the Wodenbeck family with a non-ferrous metal foundry that was once attached. Another spring was located in a residential building on the “Unterste Flieth” homestead downstream, in the rock cellar of the “Hausmann” house. This source river was with an origin at about 250 m above sea level. NHN is the highest and longest and thus hydrologically the main source of the Angerbach. At the Angerhäuschen another source river coming from the Bastersteich reached the young body of water. In the further course the Angerbach formed the historical border between the Honschaft Rützkausen and the farming community Große Höhe .
In 1943 a dam was built about 2.5 km below the historic Anger spring. The resulting reservoir served as a sedimentation basin for the Wülfrath lime works . The dam has a crown height of 72 m and achieved a storage height of 237 m above sea level. NHN . As a result, the entire upper Angertal was buried under the sedimentation of the limestone washing mud. The 1.3 km² large clarification pond was named the Eigenerbach, an insignificant tributary that disappeared directly under the dam. The historical Angerbach, however, was deleted from the official maps. Its upper course, cut off by the sedimentation basin, is now known as the Fliethenbeeke. After the sedimentation ceased in 1998, the former sedimentation basin was renatured . As part of the renaturation, the Angerbach is now going through a continuous course again.
Instead of the historical source branch, after the construction of the sedimentation basin, the Mühlenbach, which was 2 km shorter and originally a left-hand inlet from Wülfrath, was often referred to as the Angerbach and so was finally included in the official maps. The at only 170 m above sea level. Subterranean tributaries to the Stadtteich in Wülfrath located near the NHN are now regularly referred to as the Anger spring.
Historical meaning
After the Battle of Worringen in 1288, the peace treaty between Adolf V von Berg and the Archbishop of Cologne Siegfried von Westerburg prohibited the people of Cologne from building fortifications or castles on the Anger. The castles, manors and manors that are still numerous today may bear witness to the early Middle Ages. Gut Laubeck is located in Heiligenhaus, Haus Anger , Burg Gräfgenstein , Poensgenpark and the moated castle Haus zum Haus an der Anger are in the Düsseldorf area, Burg Angermund , Schloss Heltorf , Rittersitz Groß-Winkelhausen and in Duisburg area Haus Böckum , Haus Remberg and House Angerort .
Further historical buildings and tourist destinations are the former Auermühle watermill in Ratingen and Gut Kesselsberg , the sand mill , the Biegerhof and the former Medefurter Hof with mill in the Duisburg area . The Winkelhauser oil mill , which historically belonged to Groß-Winkelhausen , was demolished in early 2014.
course
Today's Angerbach runs through the cities of Wülfrath , Heiligenhaus and Ratingen in the Mettmann district and through the independent cities of Düsseldorf and Duisburg . While the river is characterized by a relatively steep gradient in its eastern section , it meets a low terrace near Ratingen-Lintorf and runs very flat from there to the Lower Rhine . Limestone mining in the city of Wülfrath is important for the runoff of the water. Approximately parallel to the water almost exclusively in this context was freight trains used Angertalbahn traced out.
The Anger is subject to strict flood protection , since without regulatory measures it could endanger large parts of the cities of Ratingen, Duisburg and Düsseldorf. The planning approval for the new construction of the A 44 motorway has still not been decided by a judge since 2009 following lawsuits from the cities of Ratingen and Düsseldorf, as the discharge of rainwater from the road construction agency could not be resolved.
The area around the lower Angerbach is called Angerland and corresponds to the old Bergisch Amt Angermund , which covers the north of today's district of Mettmann, Kettwig , parts of today's city of Mülheim an der Ruhr , the northern districts of Düsseldorf and most of today's Duisburg district of Duisburg -South included. In 1928 the Angermund Office was dissolved and replaced by the Angerland Office , which existed until the municipal reorganization in 1975 .
