Grumpy ponds
The Grummer Teiche , also popularly known as the Grummer Seenplatte , are a series of ten ponds in the Bochum district of Grumme , fed by the Grummer Bach and its tributaries Rottmannsbach, Schmalebecke and Albecke. They are primarily used to store rainwater or as flood protection. Due to the natural design of the facility, they are also a popular local recreation area. The city of Bochum has designated it as a landscape protection area.
location
Eight of the Grummer ponds are located in the valley of the Grummer Bach between the Kötterberg in the north and the Böckenberg in the south. Two ponds are a little higher on the slope of the Böckenberg.
history
The Grummer Bach was formerly called Grumbecke, which means something like 'Bach in the valley floor'. The valley was rich in water and swampy, and the whole area was densely forested.
The oldest Grummer pond is today's Kaiseraueteich. Even before 1900 there was a "basin" at this point, from which "the water was fed in pipes into the houses at the entrance to the Prattwinkel, into the mill and the Halsstricksche Schmiede".
In 1902, landowner Theodor Helf made the first Grummer leisure center out of the basin in his meadow. The pond was prepared for activities such as ice skating, boating, swimming, etc. and in July the excursion restaurant with terrace and garden was inaugurated. From then on, the "Kaiser-Aue" was not only a place of recreation for the citizens of Grummer, it became an attraction for the entire area. The concerts followed by fireworks, national swimming competitions and balloon rides were famous. The Kaiseraue remained a popular event location until the beginning of the 1960s, when the building became increasingly dilapidated and less used and was finally demolished in 1974.
The pond on the former Kaiseraue has been preserved and nine more reservoirs were built on the Grummer Bach in the 1970s. These are rain retention systems in earthworks that look like natural bodies of water. (Until then, Josephinenstrasse in Grumme had probably been flooded more often.)
In August 1977 the "Grummer Seenplatte" was inaugurated and since 1983 a lake festival has been held every summer. In 1989 the Grummer Teiche were baptized. Their names (from east to west): Rottmannsteich, Aggerteich, Biggeteich, Grumeteich, Kötterteich, Grumbeckteich, Kaiseraueteich, Constantinteich, Mühlenteich and Tipulusteich.
The ponds in detail
Rottmannsteich and Aggerteich
The Rottmannsteich is the highest Grummer pond and is fed by the Rottmannsbach. It is named after the farmer Rottmann, who had his farm here until 1960. Numerous beeches still grow on the slope of the Böckenberg - every now and then one falls over and is allowed to lie there, because the city maintains "close to nature". The Aggerteich is the closest pond to the Rottmannsbach. It was named after the neighboring Aggerstrasse.
Wet biotope
A few steps away from the point where the Rottmannsbach flows into the Grummer Bach, there is a small, shallow body of water that is referred to as a biotope in the city map . It is fed from nameless sources on the Böckenberg and is believed to have developed naturally. The runoff takes place in the Grummer Bach. In summer the biotope is overgrown with irises .
Bigge, Grume and Kötterteich
The Bigge pond is the uppermost pond on the Grummer Bach. It was named after the neighboring Biggestraße.
This is followed by the Grumeteich - "Grume" is also an old name for the Grummer Bach.
The next pond is the Kötterteich, named after the Kötterberg or after the Köttern ( Kotten owners ) who settled there. Opposite the Kötterberg, the Schmalebecke flows into the Kötter pond.
Grumbeckteich and Kaiseraueteich
Grumbeckteich and Kaiseraueteich are closest to the center of Grumme , directly behind the old Goeke restaurant. There is a children's playground and lots of Canada geese. The Kaiseraueteich is not only the oldest, but also the largest of the Grummer ponds. He has an island where the water birds are specially protected. Its name comes from the former Kaiseraue restaurant, in whose garden a bust of Charlemagne is said to have stood.
Constantin-, Mühlen- and Tipulusteich
The next pond at the Grummer Bach is the Constantinteich, whose name is supposed to remind of the former coal mine Constantin the Great , where many Grummer miners were employed until the beginning of the 1970s.
The mill pond is reminiscent of the mill that was in operation here on the Grummer Bach for about 400 years.
The last pond in the chain is the Tipulu pond. Its name goes back to the legend of the giant Tipulus, who shook off his shoes not far from here after an excursion into the countryside, which is how the Tippelsberg came into being.
Flora and fauna
Willows and black alders grow on the banks of the ponds, and numerous beeches and a few oaks and birches on the slopes of Kötterberg and Böckenberg . Between the trees you can find nettles and in some places horsetail . The Japanese knotweed has also spread here - it is fought by mowing it several times a year. The grass is kept short by a flock of sheep that occasionally visits the Grummer ponds.
The most common waterfowl are probably the mallards , but Canada geese and Egyptian geese have been encountering more and more Canada geese and Egyptian geese in summer . In addition, many pond fowl and some gray herons breed here . A few cormorants regularly fish at the two higher ponds on the Böckenberg .
Sports
The paths at the Grummer ponds can be used by walkers and joggers. The small pond round is a good 5 km long. The running route can be extended by making a detour to the monument to “Bone-Karl” or to the Bochum city park or to the Tippelsberg / Berger Mühle nature reserve.
Development plans
According to the 1998 landscape plan, the city plans to redesign the Grummer Bach “from the Harpener Feld to the confluence with the Hofsteder Bach in a natural way”. On this occasion, the ponds should "be placed in the shunt if possible". This means that the stream no longer flows through the ponds, but alongside. These are only let into the ponds if there are large amounts of water. This may also reduce the silting up of the ponds.
In 2019, residents founded the “Grummer Teiche Interest Group”, which aims to preserve the cultural landscape, promote the area's nutritional and recreational function, the climate-stabilizing effect of the green corridor and provide information to citizens. The wooded wetland is to be given special importance in the context of the climate emergency declared by the City Council of Bochum on June 6, 2019 , and its function is to be secured.
