The Springbach is a right tributary of the Oker, which formed the former Braunschweiger Landwehr south of Melverode and was called Grenzgraben until 2006 . It was named after its source, the Mascheroder Spring .
course
Mascher or Spring
The source of the Springbach is the Mascheroder Spring in the Feldmark southwest of Mascherode near the state road L632 to Stöckheim . The spring water has a temperature of around 10 degrees all year round. The spring is located as a small pond directly on a dirt road and has had the status of a natural monument since 1977 . Part of the spring rises on the other side of the dirt road and is connected to the pond by a sewer pipe. The drainage from the spring pond into the trench takes place via a small bottom slope. The source emerges below the chalk limestone heights gently rising to the east and marks the beginning of the Stöckheimer Mulde .
Landwehr
The Springbach runs strongly straightened to the northwest and north to Mascheroder Holz ( Jägersruh ) and follows from the location of the former Kleiner Weghaus of the former Braunschweiger Landwehr to the west. In the entire course it is relatively straight and according to the water quality report of 2002 also poor in species. On its north side it delimits the area of the Heidbergsee and the settlements Heidberg and Melverode, while on the south side it is bordered by agricultural land. Between Melverode and Heidberg it crosses under the A 36 and flows into the Oker in the South Sea region.
The Springbach is about 3.5 kilometers long and its catchment area covers 12.1 km².
Renaturation
Since 2003 and 2007, the city of Braunschweig has had a catalog of measures for a natural remodeling of the Springbach, especially in the lower reaches of the Stöckheim settlement area. Some sections have been equipped with small swings in the stream and others with flood zones.
In the Stöckheim new development area, Breites Bleek , a shallow, natural and freely accessible rain retention basin was created to relieve the Springbach before the surface water was discharged from the settlement , while an extensive tree-lined flood zone was created on the Melveroder side.
A few hundred meters before the mouth, the stream has been provided with a 100-meter-long flood ditch in the area of a park-like facility. The original stream bed is closed off at the end with an earth wall and has been a still water since then . The new course of the brook is equipped with field stones and widenings in such a way that meandering courses and shallow water zones form. Stone benches were set up on the bank and the embankment was made relatively flat with a slope of 1: 5, so that children can safely access the shallow water areas. This installation was carried out as a compensatory measure in the course of the new construction of the Oker bridge at Berkenbuschstrasse .
Historical
From 1897 the spring water was bottled as mineral water for several years, for which a steam engine was used on site.
