Aar (Dill)

BW

The eagle is a 20.6 km long, situated entirely in the Lahn- Dill-Kreis, east, so left tributary of the dill. It rises in the headwaters Ahrbach ( Brühlbach, north ) and Erdaer Bach ( south ), which flow together north of Erda (municipality Hohenahr ), and ends in Herborn Castle in the dill.

In the area of the old circle Biedenkopf ( now the town Bischoffen ) was the eagle with "h" written -Ahr - up to the Gell Bachmuhle ( Three Countries mill west of Bischoffen ), until this old border it was called in the former Dillkreis Aar. This route marks the border between the Grand Duchy of Hesse -Darmstadt and the Duchy of Nassau.

Geography

Course

The Aar runs Gladenbacher Bergland ( Nature Park Lahn- Dill-Bergland ) largely from east to west. Your headwaters to Aartalsee lies in the natural area Niederweidbacher pool ( 320.13 ), which is largely defined from the catchment area of the river and its tributaries. Even before the lake of the Aar from the left of the great stream, coming from Great Ancient cities, and the city of Erbach flows to and immediately at the beginning of the lake at Mudersbach from the right Wilsbach.

In the course of the Aar Aarsees flow to the tributaries Weidbach and sea creek from the right. The river leaves the community Hohenahr ( Mudersbach the southeast and Ahrdt in the Midwest ) and in the community Bischoffen occurs via ( Niederweidbach in the north east and Bischoffen itself in the extreme northwest and thus at the outlet of the lake ). Still in Bischoffen, but outside of the reservoir, opens the main right tributary Siegbach from the north.

From now forms the Aar approximately the boundary between the natural spaces inch beech ( 320.03 ) and, further west, L'Escaut Forest ( 320.02 ) in the north and Hörre ( 320.4 ) in the south. After the influx of Gell Bach left the districts Offenbach, Bickenbach and Ballersbach flows through the municipality Mittenaar succession. In Bicken inflows Weibach from the north flow ( = right) and Gettenbach from the south ( = left).

Last flows through the Aar Herborner districts Seelbach (inflow of food Bach from the right, then the Dernbachs from the left and the Monzenbachs from right) and castle, where it finally joins in the dill.

Tributaries

The following tributaries flow of the Aar to:

The Upper Aar, which is up to the inflow of Wilsbaches, at the beginning of the Aar valley lake, calculated, has a discharge of 470 l / s with a catchment area of ​​42.744 km ², which is relatively evenly across town Erbach ( 16.767 km ²), Aar ( 12.48 square kilometers before the town of Erbach - mouth ) and Wilsbach ( 12.342 km ²) distributed. A significantly smaller contribution to the reservoir and provide Weidbach Meerbach.

The Siegbach is by far the largest tributary, crossing the only flow at all for a source profile in the Bottenhorner plateaus in the north ridge inch beech, in which several northern tributaries of the upper reaches have their source.

All the eastern and southern tributaries of the lake Aar towards their source either in Niederweidbacher pool itself or on the northern edge of the south subsequent Krofdorf - Konigsberg forest.

The underflow fed through the Escaut forest in the north and the Hörre in the south.

Pollution

In January 2008, the eagle was heavily burdened by antibiotics, which came from a chicken farm on Aartalsee. Meanwhile, the Aar is biologically but back in order.

Traffic

Federal highway 255 follows - upriver seen - in their course of Herborn direction Gladenbach first the valley of the Aar, from Niederweidbach then that of the Weidbaches to finally cross over to the customs beech the watershed between the Aar and Salzböde. After a serpentine- rich route, it reaches Weidenhausen ( Glad Bach) the Salzböde, follows her down river to Erdhausen and then runs from Glad Bach to Niederweimar on the watershed between the Allna in the north and the southern Lahn- tributaries (from west to east) Salzböde, Walgerbach and Wenkbach.

The disused since 2001 Aar - Salzböde -Bahn followed, also first seen upriver, the opposite from Bischoffen the course of Siegbach to overcome between Eisemroth and Hartenrod the watershed between the Aar and ( Upper ) Salzböde in a tunnel and then on the Salzböde downriver to follow.

In the Middle Ages, starting around the end of the 14th century, was in Aartal a significant Fernhandelsweg, namely the younger line of the section Herborn - Marburg, the Cologne - Leipzig fair road.

Since 2006, a ring road for the Herborner districts castle and Seelbach was built along the estuary area of ​​the Aar. The ring road and exit Seelbach- East was released on 2 April 2009 for traffic. On 17 April 2009 the bypass and the departure Seelbach- West was officially opened.
