The PreÃÂnitz () is a right-hand tributary of the Zschopau River in the state of Saxony in eastern Germany and in the Czech Republic. It rises in the Bohemian part of the Ore Mountains near HornàHalà ¾e.
The upper section of the PreÃÂnitz, through the mining areas of MezilesÃÂ to its confluence with the stream Hammerbach from Dolina, was formerly known as the Hammerlebach.
Along the rest of the PreÃÂnitz as it flows northwards are the old mining town of Pà ÂÃÂseÃÂnice, which was blown up in 1973 along with the neighbouring villages of Rusová and Dolina, in order to dam the PreÃÂnitz at that point and form a reservoir. In 1976, the Pà ÂiseÃÂnice Reservoir was completed.
At the first village in Saxony that the PreÃÂnitz flows through, Schmalzgrube, it is joined by the Schwarzwasser stream from Jöhstadt.
Above the town of Wolkenstein the PreÃÂnitz finally discharges into the Zschopau.
Due to the iron ore deposits in the area there were many hammer mills along the PreÃÂnitz in the past, for example in Schmalzgrube, Oberschmiedeberg, Mittelschmiedeberg und Niederschmiedeberg.
North of the dam on the border with Saxony is the village of Kryà ¡tofovy Hamry, in which one of the seven factories that manufactured cobalt blue paint in Bohemia, the Blaufarbenwerk St. Christoph, was located until 1874.
From 1955 to 2001 refrigerators were manufactured at Niederschmiedeberg. In 1993 the factory developed the first chlorofluorocarbon- and fluorocarbon-free refrigerators under the trade name of FORON.
On the way to Steinbach in the PreÃÂnitz Valley is the show mine of Andreas Gegentrum Stolln.
From 1892 to 1986 the Pressnitz Valley Railway ran between Wolkenstein and Schmalzgrube, parallel to the PreÃÂnitz River. After its closure a walking and cycling path was built between Wolkenstein and Steinbach on the old railway embankment along which the course of the river can be followed. Between 1995 and 2000 a museum railway was built between Steinbach and Schmalzgrube on the old embankment.
