The Mühlenriede is a brook on the northeastern edge of the Papenteich plateau with an approximately 50 km² catchment area west of the city of Wolfsburg and southeast of the city of Gifhorn . The brook belongs to the Aller river system . It flows into the Allerkanal not far from the Tankumsee .

Renatured area near Fallersleben

The brook arises in the west of the city of Wolfsburg. The source streams are now completely piped, so that their source and their upper reaches are no longer recognizable. The stream comes to the surface on the A 39 near the Wolfsburg districts of Mörse and Ehmen . On the southern outskirts of these two places the Mühlenriede initially flows westwards before it bends north on the western outskirts of Ehmen. The Mühlenriede flows past Fallersleben and then covers the Mittelland Canal at Sülfeld . After crossing under the canal, the stream turns northwest towards Calberlah . After the Mühlenriede has passed the village, it bends slightly north on the county road to the Kranichsmoor and covers the Elbe Lateral Canal . It is led in an artificially created bed southwest around the Tankumsee and reaches the Allerkanal in a relatively straight line .

Tributaries

The Klein Brunsroder Riede is a left source stream of the Mühlenriede. The stream rises north of Groß Brunsrode in Flechtorfer Holz. It feeds itself from several small springs and drains both the forest area and the surrounding arable land. The water had been well developed and straightened over a long period of time. The moat has not been maintained since the 1990s, so it is partially renatured. The stream flows through intensively used arable land and is only protected in a few places by wood on the banks. In addition, over the are receiving water a pond treatment plant the wastewater discharged into the creek.

The Mühlenriede is a largely developed and straightened body of water with very little water at times. Most of the stream runs through green areas and is only shaded by trees in a few areas. Today the stream is slowly developing back to its natural state, supported in parts by renaturation measures. The first renaturation measures were completed some time ago in the Auewiesen between Ehmen and Fallersleben. In 2004, the relocation of the river bed and renaturation began in the section between Mörse and Ehmen.

Running water organisms are largely absent in the Mühlenriede. Nevertheless, there are nine animal species that are on the Red List of Lower Saxony:

Water quality

As is usual in the Lüneburg Heath, the bottom of the water consists of sand and fine gravel. The Lower Saxony water quality report from 2004 rated the chemical water pollution of the Mühlenriede in the upper and middle reaches as moderately polluted (quality class II). The underflow is critically polluted (quality class II-III).
