The Preßnitz Dam (Czech Vodní nádrž Přísečnice) is a reservoir in the Ústecký kraj (Aussig region) in the Czech Republic, on the Bohemian side of the central Ore Mountains and near Jöhstadt.
The reservoir is around 50 m deep and serves as a drinking water reservoir for the people in the Egertal and northern Bohemia. The Preßnitz, which then flows into German territory and flows into the Zschopau, is dammed. Water from the Jöhstädter Schwarzwasser (Černá Voda) is also fed into the dam through a transfer.
At the Preßnitz was the old mining town of Preßnitz (Přísečnice), which 1973–1974 including the neighboring towns of Reischdorf (Rusová) and Dörnsdorf (Dolina) was given up in order to build a drinking water reservoir in its place by damming the Preßnitz.
The 50 m high dam was built as early as 1970–1971 and in 1976 the construction was completed. The dam designer was Hydroprojekt Praha; The operator is Povodí Ohře in Chomutov.
The dam is a rubble dam with a central, interior clay seal. An inspection corridor runs under the dam. The water is extracted through two extraction towers in the storage space, one of which also serves as a flood relief.
