The Zaufensgraben is an approximately 3 km long, northeast and orographically right tributary of the Gessenbach in the area of the independent city of Gera in Thuringia .
course
The Zaufensgraben rises about 1,000 m southwest of the Gera-Leumnitz airfield at about 290 m above sea level. NN . The stream flows mainly in a south-westerly direction through Gera. In the middle section it forms a narrow notch valley in which the Zaufensgraben landscape protection area is located, which is the smallest of its kind in Gera with an area of 11 hectares. He passes the Ronneburger Höhe ( 296.8 m above sea level ) with the Ferberturm observation tower there . In the lower section, the trench is piped under Meuselwitzer Strasse . Finally the stream flows out at about 195 m above sea level. NN into the Gessenbach , which flows a little further west of it into the White Elster .
Geology and hydrology
The Zaufensgraben essentially flows through areas of the Zechstein and the Rotliegend . Some of the water flows directly over the rock. Only in the lower reaches he could deposit some clay himself. With an average gradient of more than 3%, it is one of the steepest rivers in the river system of the White Elster in the Gera area. The water flow is irregular. In some years water is carried all year round, in others the lower reaches dry up for half a year.
biology
In the gorge-like, uncultivated valley sections on the Zaufensgraben there are huge trees, mainly pastures. Apart from occasionally observed mallards, the fauna is not very water-specific. Bird species seen include goldfinches, long-tailed titmouse, golden grouse, nuthatch, jay, treecreeper, wren, hawfinch, great spotted woodpecker, green woodpecker, buzzard and sparrowhawk. In the case of reptiles and amphibians, one encounters the slow worm, sand lizard, grass snake, common toad, common frog and pond newt.
History
Surname
The name Zaufensgraben comes from the Middle High German zauche, which can mean both “dry” and “border”. Both are suitable, as the ditch does not carry water permanently and also forms the southeastern border of the Gera district.
General
In the period from the 16th to the 18th century there were mining attempts on copper ore in the Zaufensgraben. A small limestone quarry is from later times. Around 1900 there was also a brick factory in Zaufensgraben. From 1901 to 1969 the Gera-Meuselwitz-Wuitzer Railway , a meter-gauge small railway on the orographic left side, ran through the valley of the Zaufensgraben. The planned cessation of operations on December 31, 1970 was preceded by a storm on May 3, 1969. The Zaufensgraben caused such strong flooding that the railway line was washed away in several places. The Gera-Pforten station area was flooded and completely silted up, aided by the rather undersized piping of the Zaufensgraben in the lower area. After that, operations were not resumed and the station was converted into a bus station for more than 20 years. This function also disappeared with the Icarus buses. Nowadays there is a housing estate on the company premises, which, as if May 3, 1969 had never happened, shows no signs of flood protection. The same applies to the piping, which still dates from this time.
Striking
There are striking points along the Zaufensgraben, for example, at the following locations (viewed roughly downstream):
- Slightly below the source begins below the road rating the conservation area Zaufensgraben ( ⊙ ), which at some points by unauthorized construction of CJDS was affected and approximately up to the Meusel Witzer road ( ⊙ extends).
- In the upper reaches of the source near the source, the bridge of the Südosttangente stands along the federal road 92 : Stadtring Süd-Ost ( ⊙ ).
- A little southwest of the bridge of the B 92 is one of the former Gera-Meuselwitz-Wuitzer Railway ( ⊙ ).
- A Zechstein reef ( ⊙ ) extends north of the arch bridge (see below) on the Dorfstrasse in Zschippern .
- There is an arched bridge ( steht ) on the road from Zschippern , which was closed to automobile traffic due to static problems.
- A little east of the end of the street Am Südhang there was a small bridge in the course of "Colliser Straße" that collapsed and was replaced by a small footbridge ( eten ) unsuitable for cyclists .
- There is a bridge ( ⊙ ) on the footpath An der Bornhohle .
- The Lindenthaler Hyänenhöhle was located on the nearby Pfortener Straße , a height that was inhabited in the Paleolithic .
- In its lower area, the stream flows in a tunnel between its (underground) piping start ( ⊙ ) on Meuselwitzer Straße and its (underground) piping end near Wasserkunststraße ( ⊙ ).
hike
Meuselwitzer Straße leads through Zaufensgraben on the orographic right side, which turns into a hiking trail (unsuitable for bicycles). Another hiking trail runs on the route of the former Gera-Meuselwitz-Wuitzer railway , which overcame the incline from Gera-Pforten to Gera-Leumnitz along the trench. The mostly shady hiking trails are partly marked. The main hiking trail along the stream crosses it several times; in the upper part it moves away from the stream.
