Walkers who walk from hainbad to suden these days will be surprised: the creek in the wildly romantic hollergraben has dried up over several hundred meters and the smell of rot hangs in the air.
If you continue on your way in the direction of buger spitze, you will find the explanation for the unusual lack of water in this otherwise lively little river. At the inlet of the hollergraben, under the bridge of the munchner ring, mountains of stones block off the creek. Construction fences shield the land from uninvited guests.
But the barrier will not be of much use. The curiosity of passers-by is rude, finally the river is turned upside down in the middle of the hain amusement park.
It is the second intervention that elderly people can witness there. 40 years ago, during the construction of the munchner ring, the now familiar paved river landscape was created by architect bernhard winkler. At that time, the former weir called steinwohrlein was also moved 200 meters downstream. As the horseshoe weir, it was to become a bathing paradise on warm summer days for generations of young bambergers.
The steep drop that delighted human water rats also had massive disadvantages, of course, as ecologists have known for some years now. For fish and other creatures, the horseshoe weir posed an insurmountable obstacle. It is now to be demolished and transformed into a torrent-like watercourse in one step with the river landscape under the bridge. The stream, into which up to three cubic meters of water per second flow, is to provide "passage for many creatures" at the groundbreaking ceremony, state secretary melanie huml (CSU) praised the project. Construction meets the requirements of the new EU water directive. Nevertheless, it was not self-evident that, after the highly praised fischpass on the erba peninsula, number 2 in the bamberger suden could now also be realized quickly.
It is thanks to the irresistible stimulating effect of a garden show, as OB andreas starke (SPD) stated. Several donors are needed to raise the total sum of 1.1 million euros for the project: the lowen share is contributed by the tiebwerksverband obere und untere muhlen and the landesgartenschau gmbh with 750,000 euros. Smaller sums paid by the upper franconia foundation and the free state of bavaria.
The project, which is technically accompanied by the water management office kronach, is to be locked still before the end of the horticultural show in october, which has probably also financial reasons. How will the upper course of the hollergraben look then? The fall of 1.5 meters is to be distributed on a ramp with an equal slope, extending downstream for 200 meters. It is interspersed with alternating stone barriers. Concrete and paved berms are replaced by gravel and natural stones. Both together, the mabige gefalle and the construction materials, allow the creatures to migrate and at the same time reduce the costly maintenance that the construction company had to provide here recently.
But the mud-covered basin under the bridge was not inactive either. Alfred gotz of the bamberg sportfischerverein paid for the fishing out ca. 18 species of fish, including long unseen ones such as the stichling or the bitterling. Bream and eels as thick as arms also wriggled in the kascher. They were abandoned in the regnitz.
