The Weidgraben is a 3.7 kilometer long drainage ditch in the northeast of the independent city of Karlsruhe and in the municipality of Weingarten (Baden) in the district of Karlsruhe , which was re - routed in the course of the Pfinz-Saalbach correction (Pfisako, 1934–1962).

geography

course

According to the official digital water management network (AWGN), the Weidgraben begins at a pipe outlet on Greschbachstrasse in the Rossweid industrial park near Karlsruhe- Hagsfeld . According to other information, the origin lies in the Untere Hub northwest of Durlach and around 2.5 kilometers south of Greschbachstrasse ( ⊙ , 114  m above sea level ). Of the lower stroke of Weidgraben passes through an agricultural area, passes under at the junction Karlsruhe-Nord the motorway 5 (Karlsruhe- Heidelberg ) and then runs verdolt to Greschbach road.

From the pipe outlet, the Weidgraben runs almost 500 meters to the east, crosses under the motorway again and immediately afterwards the Pfinz relief canal in a culvert . Immediately after the culvert, the Beungraben from Karlsruhe- Grötzingen flows from the right . From here the Weidgraben follows the motorway in a straight three kilometers long, which runs around 100 meters further west to north-northeast. More streams and ditches flow into the Weidgraben from the right, including the Gießbach , which branches off from the Pfinz in Grötzingen .

Most of the moat is in the forest or on the edge of the forest; Areas around the Aussiedlerhöfe Im Brühl , east of the Weidgraben and south of the Gießbach estuary, as well as the Weingartener Wiesental shortly before the confluence of the Weidgraben into the Weingartener relief canal are used for agriculture . This canal branches off from the Walzbach in Weingarten (Baden) ; it flows 1.5 kilometers below the mouth of the pasture ditch coming from the left to the Pfinz, here called Pfinzkorrektion .

In the entire course from Greschbachstrasse, the Weidgraben lies in nature or landscape protection areas or forms the border between them: Nature reserve Weingartener Moor and the landscape protection areas Füllbruch-Vokkenau , Gießbachniederung-Im Brühl , broken forest area of ​​the old Kinzig-Murg-Rinne and Weingartener Wiesental .

history

In front of the Pfisako there was a body of water, sometimes referred to as a Weidgraben , which arose in the meadows north of Durlach and to the right of the Pfinz and flowed into the Gießbach roughly where the Weingarten relief canal of the Pfinz correctional flows today. The pouring stream was shortened during the Pfisako; previously it flowed north of Blankenloch into the Pfinz.

This body of water is referred to as the Weidgraben in topographic maps from 1876 and 1936 as well as in district overviews of Durlach and Grötzingen from the end of the 19th century. In a topographical map from 1840, the body of water is labeled as Gieſsbach , whereas today's Gießbach is labeled as Die Gieſs . In a publication on meadow irrigation in the region from 1995, the body of water is referred to as a watering ditch . Other, more local names were re-union digging in the lower reaches at Blankenloch and Füllbruchgraben in the area of Füllbruchs.

During the Pfisako, the Weidgraben in its current course, the Pfinz correction, the Weingarten relief canal and the Pfinz relief canal were created. The filling breach between the Pfinz relief canal in the south, the Pfinz in the west, the Autobahn in the east and the Pfinz correction in the north was set up as a retention area for floods in the Pfinz. Today's Weidgraben bypasses the retention area in the east and is the receiving water of the waters flowing in from the east. The old course of the pasture ditch through the filling quarry is still present as a mostly dry ditch and is referred to as Rossweid ditch in the AWGN .

According to an agreement from 1954, 70 percent of the maintenance costs of the Weidgraben are borne by the motorway office and 30 percent by the city of Karlsruhe and the community of Weingarten (Baden).
