The Scheidgraben is a drainage canal in the north of the Ortenau district and in the south of the Rastatt district . It arises near the municipality of Sasbach and flows around 20 kilometers through the Upper Rhine Plain near Rheinmünster - Stollhofen from the right and east into the Rhine Low Canal .

geography

course

The Scheidgraben arises under the local name Fuchsgraben in the wet meadows of a valley gully in the foothills of the northern Black Forest , which lies in the area of ​​the municipality of Sasbach between the Schänzel and Eichelsberg tubs . Heading north to north-westerly and shown in the topographical map as only occasionally bearing water, the Fuchsgraben flows for a good 700 meters through an area that is mainly used for fruit growing. In the following section, the Fuchsgraben separates the built-up areas of the city of Achern on the left bank and the municipality of Sasbach on the right bank.

After almost 300 meters parallel to the Rhine Valley Railway ( Karlsruhe - Offenburg ), the Fuchsgraben crosses under the railway line and the parallel federal highway 3 and then runs on the edge of an industrial area of ​​Sasbach to a designed biotope with a pond.

From the pond on the topographical map shown as permanently water-bearing, the Fuchsgraben flows through an area mainly used for arable farming. After crossing under the county road 3572 ( Sasbachried - Großweier ) the ditch follows the state road 87a (Achern - Unzhurst ) for around 1.5 kilometers before it bends to the right and flows northeast for around 700 meters. The Fuchsgraben approaches its right-hand neighboring water , the Sasbach , here called the Sasbach flood canal , up to almost 300 meters. Flowing northwards, the Fuchsgraben crosses the small forest area Allmend at the level of the district road 3750 ( Ottersweier –Unzhuerst) .

North of the Allmend, the connecting ditch Rossstapfen flows to the Fuchsgraben from the right , a branch of the Laufbach . From the confluence called Roßstapfengraben , the water flows towards west-northwest, crosses the federal motorway 5 (Karlsruhe – Offenburg) and crosses the built-up area of ​​Unzhurst. On the outskirts of Unzhurst, the Roßstapfengraben crosses under the Acherner Mühlbach in a culvert . Around 600 meters below the culvert, the Roßstapfengraben bends to the right and north at the small Seebusch forest area .

At the Aussiedlerhof Regenmattenhof , the Schwarzwasser flows from the left , with 9.4 kilometers the longest tributary of the Scheidgraben, which arises on the outskirts of Achern. Above and below the mouth of the Schwarzwasser, the Scheidgraben passes an agriculturally used exclave of the municipality of Lauf located around 9 kilometers southeast or forms its border. Another exclave to the north belongs to the municipality of Sasbach.

To the southeast of Bühl - Moos , the Scheidgraben crosses under the Acherner Mühlbach a second time; the bridge of the national road 87a (Unzhurst – Moos) joins the water crossing. Running about 200 meters east of the built-up area of ​​Moos, the Scheidgraben north-east of the village crosses the Bühl– Stollhofen railway line of the former Mittelbadische Eisenbahnen (MEG), which is now only served by goods traffic, and the state road 78 from Moos to Oberbruch . To the north of the road bridge, the Scheidgraben runs roughly parallel to the Acherner Mühlbach for just under a kilometer and sometimes less than 100 meters away. After crossing under Landesstraße 85 (Oberbruch- Schwarzach ), the ditch passes two partially moist forests, the Muhrenger and the Niederwald .

At the level of the Niederwald flows from the right Sandbach flood channel , which in Bühl- Vimbuch from Sandbach branches and flood retention area Abtsmoor happens to an ordinary high water retention space of 2.2 million cubic meters.

From the mouth of the flood canal, the Scheidgraben turns north-west to west-north-west; it runs roughly parallel to the Laufbach and its receiving water, the Sasbach , which bears the local name Sulzbach here . The Scheidgraben and the Sulzbach pass the southern outskirts of Rheinmünster - Stollhofen ; the water level of the Sulzbach is higher than that of the Scheidgraben. Between the Acherner Mühlbach in Schwarzach and the Sulzbach near Stollhofen there is a cross connection to the Kanalbach , which crosses the Scheidgraben at Stollhofen on an aqueduct . Above the former Stollhofen town mill located on the Sulzbach, water can flow from the Sulzbach to the Scheidgraben via a cross-connection, also called Sulzbach .

At the height of Stollhofen, the Scheidgraben is crossed by the state road 75, the former federal road 36 from Rastatt to Kehl . The Scheidgraben joins the Rhine Low Canal just under a kilometer west of Stollhofen from the right and east , which joins the Rhine after 17 kilometers near Wintersdorf from the right .

history

The Scheidgraben was created in its current form during the Acher-Rench correction (Areko, 1936–1967). The AREKO should be equally safe flood control as a sufficient drainage capability reach and drainage of waterlogged or marshy areas, in addition, the water supply for should be in the existing water mills , power plants and irrigation remain. As far as possible, separate watercourses were created for flood protection and drainage, independent of the existing streams and rivers. Within this concept, the Scheidgraben has the function of a drainage channel. Drainage canals were created with an average cutting depth of 1.50 meters. In order to be able to manage the groundwater , support gates were installed.

Topographic maps from the time before the Areko show that the Scheidgraben was created from the connection of existing flowing waters, which were previously mainly tributaries of the Achern Mühlbach. For example, the Fuchsgraben, today the upper reaches of the Scheidgraben, continued along the road 87a (Achern – Unzhurst) and flowed into the Achern Mühlbach in Unzhurst. The lower part of this body of water is included in the AWGN as the Alter Fuchsgraben ; it drains the area east of the Achern district of Großweier .

South of Bühl-Moos there was a body of water of the same name before the Areko in today's route of the Scheidgraben, which flowed into the Achern Mühlbach from the left. Still shown as meandering around 1840 and called Scheidbach , it appears on a map from the beginning of the 20th century as a straightened ditch.

The longest tributary of the Scheidgraben, the Schwarzwasser , turned north of the hamlet of Litzloch to the west in the 1930s , passed the hamlet of Michelbuch , flowed through the Fünfheimburger Wald and flowed into the Acher near Lichtenau . Today the upper reaches of the Schwarzwasser are connected to the Scheidgraben via drainage ditches. The middle part operates under the name of Fünfheimburger Waldgraben and flows to the Scheidgraben over the Schwarzwasser. The lower reaches of the former black water continue to bear its old name; it branches off from the Fünfheimburger Waldgraben. The five Heimburger forest was a Mark Forest , which was divided among the 1,800 participating in the cooperative communities. By 1840, significant parts of the forest had been cleared and used as meadows.

At the height of Stollhofen , the forerunner of the Scheidgraben was called Landhagbach or Griesbach . Together with other bodies of water, it served to infuse the foreland of the Bühl-Stollhofener line . The canal stream , which was laid out in 1803 to improve the water supply to the Stollhofener mills, crossed the Landhagbach on an aqueduct made of oak . Today's concrete structure was built in the course of the expansion of the Scheidgraben around 1956.
