The Schwarzach is a left tributary of the Naab in the Czech Republic and Bavaria. It is around 95 km long with its left, north-eastern upper course. This is sometimes seen as an independent river under the name Böhmische Schwarzach (Czech: Nemanický potok ).

course

The Schwarzach rises in the Czech part of the Upper Palatinate Forest (Czech. Český les) east of the village of Závist (German Neid , municipality Rybník ) directly on the European main watershed ; Only a few hundred meters north of the source is the source of the Radbuza , which drains over the Vltava and Elbe to the North Sea. Flowing almost exactly south in the upper reaches, the Schwarzach crosses the border to Bavaria shortly after the place Nemanice (German water soup ), from which its Czech name Nemanický potok is derived, where it follows the main westward direction from Waldmünchen .

Other places on the Schwarzach are Schönthal , Rötz , Neunburg vorm Wald and Schwarzach near Nabburg . To the west of the mouth of the river Naab is the Schwarzenfeld market .

The "Swarza" was mentioned as early as 1250. Numerous mills, saws, hammers and, in the middle of the 18th century, glass grinding and polishing works were built on the Schwarzach. Around 1850 there were over 30 grinding and polishing works on the Schwarzach, whose decline began before the Second World War.

Sometimes the approximately 24 km long upper course of the Schwarzach, which rises in the Czech Republic, up to the confluence of the Bavarian Schwarzach is also called the Bohemian Schwarzach and sees it as an independent river. With this view, the Schwarzach would only arise from the confluence of the left Bohemian and right Bavarian Schwarzach near the Waldmünchner district Kritzenast .

Flood regulation

The flow system goes through three reservoirs for flood control : the at Waldmünchen located Perlsee , the at Treffelstein located Silver (from the Bavarian Schwarzach is traversed, a tributary of the Schwarzach) and at Rötz located Eixendorfer reservoir . The Perlsee has an area of ​​about 21 hectares at the permanent damming destination, the Silbersee about 55 hectares. The Schwarzach is dammed between Neunburg vorm Wald and Rötz for flood protection and electricity generation to (in normal congestion) about 100 hectares of the Eixendorfer See . Eixendorf, Wutzschleife, Höllmühle, Obermühle, Seebarnhammer and a section of the former Bodenwöhr – Rötz railway sank into this lake . The dam was put into operation in 1975.
