The Perlbach is a brook in the Upper Palatinate that joins the Wiesent south of Wörth an der Donau from the left .

The stream has its origin in the Falkensteiner Vorwald near Niederroith in the municipality of Wiesenfelden . The upper course bears the name Gschwellbach up to the mouth of a nameless brook west of Weihern . The Perlbach and its upper course Gschwellbach flow through the communities of Wiesenfelden, Rettenbach and Wörth adDonau.

course

The Perlbach flows as a torrent through the Perlbachtal , also called Gschwelltal after an older name , initially towards the southwest and takes in several rivulets. Shortly before Wörth it flows through the "paradise" with the 407 m high Jägerbuckel in the west and the 443 m high Gschwellberg in the east. At the northern entrance to the city it feeds the forest pool , a natural pool, and then divides. While the eastern reaches of Bach's partly natural, partly in a fixed stream bed, which the Reich Labor Service was extended from 1933 to 1935, the city flows through the south and the Wörther Peter's Square , the main road in 2146 under crosses, flows the western running, even Mühl- or city Bach called, through the city center to reunite with the eastern run in the district of Sand . As early as the end of the 19th century and into the 1960s, large parts of the western Mühlbach or Stadtbach were laid under the surface in an artificial creek bed. In the district of Sand , the eastern part crosses under the state road 2125 shortly before the confluence , and then reunites to cross under the federal motorway BAB 3 , flow a good two kilometers further south and flow into the Wiesent at a triangular lake area.

history

Historically, the middle course was also called Schwellbach , Gschwellbach or Gschwell . The underflow was also Osterbach called

Pearls

The name Perlbach goes back to earlier stocks of the river pearl mussel between the beer cutter mill and the city of Wörth. It was one of four pearl brooks in the former Stadtamhof rent office .

Historical economic importance

For centuries, the Perlbach was of great economic importance for the Woerth market at the time . In a physics report around 1860, it says: "This Perlbach drove the trades in the Roth, Gschwöll or Sägmühl, the Lasermühl and then the two mills in Wörth" . In fact, according to today's knowledge, there were eight mills , three sawmills and three engines. Until the end of the 15th century there were no mills or paths in the Gschwell Valley. Up to this time the "Gschwöll", as the stream was called in the vernacular at the time, was dammed for wood production. The first mill on the stream was built in Schmalzgrub, it was dismantled before the turn of the last century. Photo documents of the beer cutter mill have survived to the present day. In 1976 this wasteland was deleted from the list of place names. The property was uninhabited for a long time and was derelict. Today only a few remains of the wall remind of it. Other well-known mills in Wörth am Gschwellbach, as it is still called in Wörth, were the court and sand mill. The Hofmühle (a purveyor to the Regensburg prince-bishops at Wörth Castle ) was the last mill on the Gschwellbach to close in 1963; the sandmill is the last mill in the city that has been completely preserved to this day; its operation was discontinued in 1956. For a long time there was a water branch from the Perlbach to the “Bachweiher” in front of the Hofmühle . This is where the ice for cooling beer from the Wörther Zierer brewery was extracted in winter. After the Hofmühle , the stream flowed in the direction of the earlier bathing pond, which was finally filled in in 1926, and from there to the former location of the “Zur Walch” engine (stands for drifting and kneading) that pumped the water up to Wörth Castle. The water of the Perlbach was also used in a tannery in the south of what was then the market.

environment

Due to the good water quality, it is a salmonid water and home to various crustaceans and mussel species. In paradise, the beaver has settled at the brook and created a biotope with wet meadows . Shortly before the mouth, the municipal sewage treatment plant of the ZV Wörth (expansion size 7750) uses the stream as a receiving water .

economy

Apart from the fact that it supplies the water for the Wörther Waldbad , the stream no longer has any economic significance for the city of Wörth.
