The Nonnenbach is a nearly 17 km long, a total of about west-southwest of ongoing tributary of Lake Constance in Kressbronn in Baden-Württemberg Bodenseekreis . Its name is derived from the old German word Ungenbach = Unkenbach .
course
The stream rises southwest of the village of Isigatsweiler, which belongs to the municipality of Achberg, and initially flows in a southwestern direction, past Siberatsweiler , Rudenweiler , Saßenweiler , Dentenweiler , Rengersweiler and Hörbolz . From Bechtersweiler and passing under the federal highway 31, it flows - forming the municipalities ( Wasserburg districts Hengnau and Selmnau - Kressbronn ) and the state border (Bavaria – Baden-Württemberg) - in a westerly direction to Kressbronn on Lake Constance. Past the districts of Krummensteg and Arensweiler, the Nonnenbach flows through the center of Kressbronn and finally flows into Lake Constance at the lido.
In old maps, the Nonnenbach in the middle course is also referred to as Gränzbach or Grenzbach .
On the way to the mouth, the stream is consistently accompanied by lush bank vegetation, mainly alder , ash and willow . It largely crosses small forests and agricultural land. The roots of the trees, some of which protrude into the stream, provide a habitat for young fish and small organisms such as river flea shrimp .
Tributaries
From the source to the mouth, the Nonnenbach takes in the following tributaries in addition to many unnamed streams:
- Outflow of the Hermannsberger Weiher (l), near Rudenweiler
- Drainage of the Degersee (r), near Hörbolz
- Ditch from the Burgstallmoos (l), northwest of Hengnau
- Fallenbach (r), center of Kressbronn
use
tannery
A tannery was once operated on what is now the green space on Kressbronner Hauptstrasse . To water the hides and skins, the tanner needed a lot of water that was taken from the Nonnenbach. The wastewater reached Lake Constance unhindered and treated with the Nonnenbach.
Mills
Four mills are or were operated on the course of the Nonnenbach . The Martinsmühle is located just outside of Bechtersweiler ; electrical energy is still generated here with the help of water power. In the municipality of Kressbronn, the water of the Nonnenbach used to drive three mills. The upper , middle and lower mill are still there, the middle mill is still in operation. A street name, a weir system and the former mill pond bear witness to the Untermühle - its history can be traced back to around 1400.

Renaturation
In the winter and spring of 1996, work began in Kressbronn to renature the Nonnenbach, which had been partially built as a canal over thirty years earlier . Between Bodanstrasse and the confluence with Lake Constance, the solid brook bottom and the solid side walls were first removed. The subsequent dredging gave the stream more space and a slightly curved course. Small trees, bushes and reeds were planted. In the second section, the area above Bodanstrasse along Irisstrasse was renatured in 1998 . As a result of the work, the stream now has pools again , small gravel banks at low tide and an increased fish population.
bad luck
On July 21, 2004 a disaster occurred on the upper reaches of the Nonnenbach: When liquid manure was being pumped over, a pipe connection burst and many liters spilled into the creek and ultimately into Lake Constance. Due to the late arrival after 6 p.m. there was no need to issue a bathing ban. Numerous dead fish remained in the Nonnenbach: streams , minnows and brown trout - the former were on the red list of fish species in Baden-Württemberg - were wiped out, grayling , bullheads and other fish species were severely decimated.
The Nonnenbach in literature
The German writer Martin Walser (* 1927 in Wasserburg on Lake Constance) mentions the Nonnenbach both in his 1979 novel Seelenarbeit :
“He saw bends in the Nonnenbach, deep under the corner wood, litter meadows, alder trees. What dark resting places are created by the fact that the brook eats away the bank in places, but then has to leave it behind at the next group of alders. Pure dark mirrors emerge behind the root associations of such alder pulpits. (...) As a child, Xaver was often down by the Nonnenbach for days and preferred to bend over the quiet, dark spots in the bends in the brook. I reached in my arm and let it break from the water level. "
as well as in the 1998 novel Ein springender Brunnen
“... and from Hengnau to Kümmertsweiler it's a maximum of three kilometers. Beeline. In reality it goes uphill behind Hengnau, then through the Atzenbohl forest deep down to the Nonnenbach, over the Krummen Steg and immediately up again very steeply to the hamlet called Kümmertsweiler. "
and in his 1966 novel Das Einhorn :
"... Tough, said Anselm, as you can see, punctuated by too many alders, the Nonnenbach winds its silent tale down through the valley."
Others
- In today's Kressbronn, both the Nonnenbach School and the footpath " Am Nonnenbach " from the train station to Seestrasse are named after the Nonnenbach.
- The municipality of Kressbronn emerged in 1934 from the previously independent offices of Hemigkofen and Nonnenbach .
