The Černé jezero (German: Black Lake) is the largest glacial lake in the Bohemian Forest . It is located on Czech territory in the area of ​​the town of Železná Ruda ( cadastral municipality Hojsova Stráž ) and is the largest natural lake in the Czech Republic. It is framed by the 320-meter-high Jezerní stěna rock face . The bedrock is mica slate , covered by a nine-meter-thick layer of mud that has formed over thousands of years from the pollen of the surrounding trees.

The Black Lake is less than a kilometer east of the German border. Therefore, the area was barely accessible to the public until the fall of the Iron Curtain . This circumstance was exploited by the Czechoslovak secret service in 1964 when, together with the KGB , they sank boxes with old Nazi documents from the Reich Security Main Office in order to subsequently “discover” them there. As part of the secret service Operation Neptune , this operation was supposed to expose West German agents who were active in Eastern Europe and to induce the West German secret services to stop working with these agents.

The nature reserve Black Lake and Devil's Lake ( Černé a Čertovo jezero ) was established in 1911 when the area belonged to Austria-Hungary .

The oldest pumped storage power plant in the Czech Republic was built here between 1929 and 1930, with the lake as the upper storage basin. The power plant is located at the Pod Černým jezerem deep basin on the Úhlava .

The main European watershed runs between Černé jezero and Čertovo jezero , just 1.5 km to the south-east . While the Černé jezero, like many other Czech lakes , drains towards the Elbe , the Čertovo jezero, like the Bavarian cirque lakes , lies on the Danube side of the watershed.
