The Ohrn is a second- order body of water about 32 kilometers in length in the northeast of Baden-Württemberg . It rises in the district of Schwäbisch Hall, east of Bubenorbis , a suburb of the municipality of Mainhardt , at an altitude of around 470 m and flows into the Kocher in the Hohenlohekreis near Ohrnberg , a district of Öhringen , at around 176 m above sea level . Your step-edge bay in the Keuper Mountains between the Waldenburg Mountains and the Mainhardt Forest around the village of Untersteinbach is called the Steinbach Valley .

geography

course

The Ohrn on their lower course between Unterohrn and Ohrnberg

From its source the Ohrn flows to the northwest, shortly before Schuppach it reaches the Hohenlohekreis with the Pfedelbacher district and from there to Cappel through the valley section called Steinbacher Tal . Here it flows in meanders , in the midst of wide meadows, above which the slopes are largely covered by vineyards and orchards. Between Stegmühle and Cappel the Ohrn crosses the municipality boundary to Öhringen. In Cappel she turns west on a bulging slope. It partially flows through the town of Öhringen in an artificially created river bed. Up to Unterohrn the Ohrn remains in the relatively soft layers of the Lettenkeuper. From there to the confluence with the Kocher it runs in the hard Upper Muschelkalk in a valley that is cut ever deeper.

Nature, the environment and protected areas

The Ohrntal near Schuppach
The historic parish bridge in Untersteinbach

Natural park

The source of the Ohrn and the upper course of the Ohrn are in the Swabian-Franconian Forest Nature Park .

FFH protected area

On January 1st, 2005 the course of the Ohrn was registered as a protected area according to the European Fauna-Flora-Habitat Directive . In the case of the Ohrn, this affects two FFH areas. Between the confluence near Ohrnberg to Untersteinbach, this is the area with the number 6822-341 Ohrntal and Kochertal near Sindringen , between Untersteinbach and the Ohrnquelle the FFH area 6823-341 Waldenburger Berge .

Special animal species in the Ohrntal are:

In the Unterohrn thus live alongside trout also under strict protection lampreys , which only occur in waters with excellent quality.

Landscape protection areas

The valley of the Upper Ohrn, which is wooded almost to the end, from the source at Bubenorbis to the confluence of the Katzenbach, in which the municipal areas of Mainhardt and Michelfeld meet, has been under the name of the Ohrn source area (with Fir blade, sand blade and mouth of the Katzenbach) with a size of 79 hectares designated as a landscape protection area, it bears the protection area number 1.27.012.

For the section from the mouth of the Katzenbach to the Pfedelbacher district Unterhöfen - with the exception of the local areas themselves - the landscape protection area Steinbacher Tal with peripheral areas (Upper Ohrntal) was established on April 16, 1991 by an ordinance of the district office Hohenlohekreis . The protected area extends over a district boundary. Its larger part is located in the Hohenlohe district (no.1.26.026) has an area of ​​1,696 hectares, a smaller peripheral zone in the Schwäbisch Hall district in the district of Mainhardt near Frohnfalls (no.127.071) comprises 103 hectares on the upper waste of the Keuperstufe .

The lower Ohrntal downstream from Unterohrn in the Öhringer submarkets Schwöllbronn , Baumerlenbach , Ohrnberg and in between also briefly the Westernbach submarket of Zweiflingen with a total area of ​​284 hectares has been known as the Ohrntal (No. 1.26.005) since January 15, 1963 . placed under protection by an ordinance of the then district office of Öhringen.

Ohrntal cycle path

In 2016, the town of Öhringen laid out the 8.8-kilometer-long Ohrntal Cycle Path from Unterohrn in the lower Ohrntal to Ohrnberg at the mouth, mostly new. In addition to the seven existing bridges over the Ohrn, new bridges had to be built for its alignment. These are marked with the rainbow colors.

Flood protection

  • The flood dam at the Cappel retention basin

  • The Ohrn during high water along the old town of Öhringen

  • The ear terrace in Öhringen during high tide

Ear correction in Öhringen 1955/56

The frequent flooding of the old town of Öhringen during floods as well as urban planning measures and the drainage of the inner city were the reasons for a correction of the Ohrn. Until 1955, the Ohrn ran on the site of today's sports stadium to the Allmand . There it was divided into two arms at a weir: one arm ran directly along the city wall, the second arm, as it is today, through the courtyard garden.

The new Ohrn runs along the Cappelrain through the Hofgarten to Heilbronner Straße. The main collector for the sewage was relocated in the old bed of the Ohrn along the city wall. A stone arch bridge in the course of the little street from the Hirschgasse in the old town to the old town of Öhringen, under which today there is only a pedestrian path, clearly shows the old course.

The air and outdoor pool on the former Ohrn was given up in the course of these construction measures.

Ear correction in Öhringen 1999/2000

After the severe floods in Öhringen in 1993 and 1996, corrections were made again to the Ohrn and Schleifbach in Öhringen in 1999 and 2000. The bridge passages and the ear bed were enlarged. A permanent dam was built along the Ohrn to protect the old town. The Kultura event hall was also secured with a dam. The ear terrace, a platform for events, was created below the Kultura.

Flood retention basin near Cappel / Oberohrn

Between Cappel and Oberohrn there is a flood retention basin built in 2006/2007 and designed for 50-year floods . The 240 meter long and 6 meter high earth dam that closes off the basin has a combination structure consisting of a bottom outlet and flood relief with three segment gates and three movable weir flaps. The discharge from the 320,000 m³ storage space of the flood retention basin is designed in such a way that the discharge of the Ohrn at the Hornberg Bridge below in Cappel does not exceed 37 m³ / s. The impoundment area is partly on the Pfedelbacher district and extends as far as the village of Oberohrn . The catchment area is about 70 km². To compensate for the interference in nature and the adjacent NATURA 2000 area Ohrn and Vogelhalde through the construction of the flood retention basin, the ecological continuity of the Ohrn weir was established in Möhrig. This makes the ear between its mouth in the cooker and the upper ear for fish through again.

Renaturation for the state horticultural show

In preparation for the state horticultural show in 2016, the Ohrn between Cappelaue and Hofgarten was renatured. In the Hofgarten, the earlier course of the Ohrn along the city wall was made visible again by an artificial stream.
