The Alte Bach (other names: Kleine Pfinz and Alte Pfinz ) is a brook in the east of the city of Karlsruhe and in the north of the Karlsruhe district . The water runs mainly in the Upper Rhine Plain as a drainage ditch west of the Pfinz river .

course

upper part

The brook was first documented in 1535 under the name “die allt bach”. At that time, the origin of the water was in a swampy area of ​​the Kinzig-Murg-Rinne between the present-day Karlsruhe districts of Durlach and Rintheim . In the 17th century, the Alte Bach was developed as a drainage ditch to drain the swamps. As early as 1588, the Landgraben was created as a direct connection to the Rhine to drain the area .

In the course of drainage measures, the Tiefentalgraben was connected to the Alte Bach in 1960; today the Alte Bach  ⊙ is being built between Karlsruhe- Grünwettersbach and the federal motorway 8 not far from the school in the district. The stream first crosses under the motorway and runs through the Hurenklamm and Hohenwettersbach to a flood retention basin ⊙ near the Zündhütle and further underground through Durlach to the Untermühlsiedlung. The stream then crosses the Elfmorgenbruch ⊙ and flows through the Hagsfeld district . To the north of Hagsfeld, the Alte Bach crosses the Pfinz relief canal in a culvert ⊙ . At the waterway crossing, water can be transferred from the Alte Bach into the relief channel. Between 1818 and 1936 the deer canal , which was created to water wild animals in the Hardt Forest , branched off here .    

In the further course the Alte Bach reaches the area of ​​the city of Stutensee , flows through the place Büchig and runs on the eastern edge of the district Blankenloch . From around 1700 the Alte Bach in the Blankenloch area had the function of a deep drainage ditch. The water that was taken from the high rivers Pfinz and Heglach and used to irrigate meadows drained into it. The Blankenlocher Dorfbach also drained into the Alte Bach , which took its water from the Pfinz, crossed the Alte Bach on a channel and ran through the Blankenloch main street until 1962. During the Pfinz-Saalbach correction , the Alte Bach in Blankenloch was relocated around 200 meters to the east and since then has also been called the new Alte Bach .

Today the Alte Bach crosses under the Heglach  ⊙ southeast of Stutensee Castle and flows into the Pfinz  ⊙ .

Lower part

Before the Pfinz-Saalbach correction, the watercourse continued further north. In the official digital water management network (AWGN) the lower part of the Alte Bach is assigned to the extended Pfinzkanal . In topographical maps and in local usage, the body of water is still referred to as the Alte Bach.

At the present time there is a stream bed from Stutensee Castle  ⊙ and a mostly dry ditch to Friedrichstal , another district of Stutensee. After crossing Friedrichstal underground, the Alte Bach runs parallel to the Heglach; before 1739 it flowed into the Heglach  ⊙ at the boundary between Friedrichstal and Graben .

In 1739 the Galgengraben (also known as the Hochgerichtsgraben ) running north-west through the Hardtwald was connected to the Alte Bach. Also known today as the Alte Bach , the Hirschkanal flows into the moat in the Hardtwald. When it emerges from the Hardtwald, the Neugraben branches off at the Galgengrabenschleuse  ⊙ . The Alte Bach, now also known as Scheidgraben, turns to the west. Both ditches used to be used to irrigate meadows in the communities of Graben and Liedolsheim . At present the Alte Bach is connected to the Distelstückergraben  ⊙ . Distelstückergraben and Neugraben flow through the Oberbruchwiesen nature reserve and then merge with other ditches to form the Extended Pfinz Canal, which crosses under the Pfinz and Saalbach Canal to the east of Rußheim and flows into the Lower Rhine Canal to the west of Huttenheim . The Lower Rhine Canal drains into an arm of the Old Rhine near Philippsburg .
