The Ried Canal is an 18-kilometer-long drainage canal in the Upper Rhine Plain that flows into the Rhine via the Gold Canal quarry pond near Elchesheim-Illingen . It is the receiving water for areas in the Rastatt district and in the Baden-Baden district in Baden-Württemberg .

geography

course

The Riedkanal branches off to the right under the local name Mühlbach south of Iffezheim from the Sandbach . The junction is immediately below a 5 meter high step that marks the border between the natural spatial sub- units of the Stollhofener Platte and the Rastatt Rhine Lowlands; Nearby is the intersection of federal road 500 ( Iffezheim - Baden-Baden - Schwarzwaldhochstrasse ) with state road 75 (former federal road 36 , Rastatt - Kehl ).

For around 1.2 kilometers, the Mühlbach follows the step to the north and runs in an old Rhine channel. which is partly occupied by a moor . On the outskirts of Iffezheim, the Mühlbach enters an approximately 1.2-kilometer-long Verdolung . From the end of the Verdolung, known as the Ried Canal , the water flows through a three-kilometer-long straight north-east facing an area with buildings around the Iffezheim horse racing track and then the field corridor north of Iffezheim. The canal crosses state road 78b and a railway line , both of which lead to the Wintersdorf Rhine bridge . The northern part of the straight belongs to the district of Sandweier , a district of Baden-Baden . To the north of the railway line, the Ried Canal forms the border between the Rastatter Ried nature reserve and the Geggenau forest , from which it flows into the Mühlwerlgraben using an old course of the Rhine.

Approximately at the bridge of the connecting railway to the Mercedes-Benz Rastatt plant , the Ried Canal swings into an old loop of the Rhine that runs roughly to the north. The approximately 5-meter-wide canal flows through the Rastatter Bruch nature reserve . At the Benz plant, the canal leaves the old course of the Rhine and follows the east and north borders of the plant; To the north of the plant, the Rheinau district of Rastatt extends to the canal.

To the west of Rheinau, the Ried Canal swings back into an old course of the Rhine and crosses under Landesstrasse 77 (Rastatt– Plittersdorf ). On both sides of the state road 78a (Plittersdorf - stone walls ) the canal runs in an artificially created water bed. To the left and west of the canal is an old watercourse attributed to the Murg, which is now traversed by the Hofwaldschlut branch . Running from the state road 78a in a north-westerly direction, the Ried Canal roughly follows the canalised Murg for around two kilometers . Just before the main Rhine dam, the canal bends to the right and in a culvert crosses the Murg, which is surrounded by backwater dams. Between Rastatt-Rheinau and the culvert, the watercourse lies within another sub-area of ​​the Rastatter Ried nature reserve .

Below the culvert, the five-kilometer-long Altmurg flows from the right , which arises on the outskirts of Rastatt and - in part using old Murgl courses - drains the area to the right and northeast of the Murg. One of its tributaries is the Haftgraben, a branch of the Federbach , which is the receiving water of the part of the Rhine lowlands that adjoins to the north. At the tributary of the Altmurg there is a pumping station that ensures the receiving water from the Riedkanal and Altmurg when the Rhine water levels are high. Below the pumping station, the Ried Canal uses an old debris flow that lies on the edge of the Silberweidenwald stone walls nature reserve .

At the level of Elchesheim-Illingen, the Ried Canal flows through the Gold Canal , an almost three-kilometer-long and up to one-kilometer wide quarry pond, which was created in the 1930s and is now mainly used for local recreation. The quarry pond is followed by a body of water around 750 meters long and between 50 and 100 meters wide, which flows into the Rhine from the right and south at Rhine km 347.3 . The quarry pond and its connection to the Rhine are designated as a state waterway in the Water Act for Baden-Württemberg .

history

Iffezheimer Mühlbach

A mill in Iffezheim was first mentioned in 1466. The associated Mühlbach is an artificially created body of water; this is also assumed for the course of the Sandbach through the Stollhofener Platte. It is said to have been derived from the Kinzig-Murg-Rinne in the 14th or 15th century ; Before that, the Sandbach near Sinzheim -Tiefenau is said to have flowed further north, where, together with the Oos, it fed the later drained Landsee , which stretched between Oos , Sandweier , Niederbühl and Haueneberstein .

The Iffezheimer mill repeatedly suffered from a lack of water, which is why a mill pond was created in 1592 . In the 1620s the miller complained of a lack of water, as water was taken to irrigate the meadows in Sinzheim and Halberstung . The community of Iffezheim also pushed for a well-filled Mühlbach to be prepared for conflagrations. In the 1700s, there was a lack of water because the Sandbach was diverted to artificially flood the foreland of the Bühl-Stollhofener line . In 1607 the miller from Iffezheim was accused of damming the water too high, which is why the Sinzheim district was flooded.

In 1802 the lower reaches of the Mühlbach between the mill and its mouth was relocated to the Old Rhine through which the Mühlwerlgraben flowed. A comparison of topographic maps shows that the upper reaches of the Mühlbach was straightened in the second half of the 19th century and relocated to the east closer to the stepped terrain. The work may have been related to the creation of a system of ditches to water meadows in the sand mats to the west. In 1875 new washbasins were built on the Mühlbach, which were an important meeting place for the women of Iffezheim. In 1878 a steam engine was installed in the mill. In the course of channeling the Iffezheimer sub-village of Mühlbach 1959/1960 was verdolt what was justified by the outgoing stream from odor nuisance and hygiene hazards of rats, mosquitoes and gnats.

Ried Canal

The name Riedkanal is derived from the name Ried for the area around what is now the Rastatt districts of Ottersdorf , Plittersdorf and Wintersdorf . The initiative to build the Ried Canal came from the board of directors of the Murg district in 1812 . The plan was to build a canal between Iffezheim and the mouth of the Murg, which would drain 32 km² of land and make it usable for agriculture. The sewer should be able to accommodate a discharge of 2 to 3 m³ / s at Iffezheim and 20 m³ / s at the mouth. In April 1817 the communities of Iffezheim, Sandweier, Wintersdorf, Ottersdorf, Plittersdorf and Rastatt founded a competition that built the Ried Canal from 1827 onwards. The canal, which was completed after several years, flowed into the Murg from the left across from the stone walls .

In 1906 the competition was dissolved because the distribution of the costs of maintaining the canal was considered unjust. In the following years, the communities maintained their respective banks, which led to a severe neglect of the canal until 1933.

In 1933 the Riedkanal association, which still exists today, was founded. The current confluence with the Rhine was built by 1938, which reduced the water level when the Rhine flooded. The culvert under the Murg was financed by the Baden state. It is 112 meters long, consists of two tubes with a cross-sectional area of ​​4.3 m² each and can discharge up to 25 m³ / s of water. In addition, the canal was deepened and drainage ditches were added, for which the name "Schnaken ditches" became popular. The pumping station near stone walls was built in the 1960s. It is equipped with four pumps; When the Rhine floods, two pumps each lift 3 m³ / s of water from the Ried Canal, the other two pumps with 1.5 and 0.5 m³ / s are responsible for the Altmurg .

Renaturation

Mercedes-Benz Rastatt plant. The Ried Canal runs from left to right between residential buildings and the factory premises.

In mid-1986 Daimler-Benz announced that it wanted to build a new production plant in Rastatt. The planned factory site was traversed by the Ried Canal. Parts of the site were designated in the regional plan as an area of ​​"highest ecological importance"; In addition, the plans collided with a concept for the protected area that had been drawn up shortly beforehand. Since a nature conservation association was entitled to take legal action because of its property and the company was under time pressure, the so-called Rastatt agreement was reached , in which the nature conservation associations waived a lawsuit and the state government promised compensatory measures worth 30 to 40 million DM . Among other things, the relocation of the Ried Canal, the renaturation of the Federbach , the designation of nature and landscape protection areas and restrictions on gravel mining were planned. Since some of the compensatory measures later turned out to be impossible, the state and the city of Rastatt founded the Rastatt Environmental Foundation , from whose foundation capital of DM 5.5 million further projects were financed. Between 2011 and 2015, funds from the European Union were also available through the LIFE + project Rheinauen near Rastatt .

After the Benz factory was established, sections of the Ried Canal near the Geggenau forest and the Hofwaldschlut were redesigned to be more natural. The bank reinforcement was removed and dead wood and stones were introduced into the river bed in order to increase the variety of currents and structures. In addition, oxbow lakes, flood channels, steep walls and flat banks were created. In March 2014, the previously largely been silted Hofwaldschlut reconnected to the Riedkanal. Since then, most of the water has usually flowed off via the Hofwaldschlut; the parallel section of the Ried Canal serves to relieve the flood. Trenches in the vicinity of the Ried Canal were also redesigned by widening and, in sections, deepening. The ditches once dug to drain the Rhine lowlands are now the only remaining habitat for some animal and plant species.

At the Iffezheimer Mühlbach, the fields in the sand mats were converted into extensively used meadows in 1985. At times the meadow irrigation that was abandoned in the 1950s was resumed. The occasion was a project to reintroduce the white stork , which needs moist meadows to forage. In autumn 2009, the near-natural redesign of the Mühlbach, which previously ran like a canal between dams, was completed. The dams were partially removed in order to connect the water with the adjacent forest and the sand mats. The stream bed was dredged, side arms were created and obstacles were introduced. At the beginning of 2010, the sheep weir in the Sandbach, which previously controlled the inflow to the Mühlbach, was demolished and replaced by a rough ramp .
