The Flaje Dam (Fláje Dam) The Flaje Dam is a major drinking water reservoir in the Czech part of the Ore Mountains. * Location: It is located in the Eastern Ore Mountains, northwest of the municipality of Český Jiřetín (Georgendorf) and southeast of the town of Fláje (Fleyh), after which it bears its name. It is relatively close to the German-Czech border. * Purpose: Its primary and most important function is to supply drinking water to the region around Most (Brüx) and other parts of Northern Bohemia. Therefore, access to the lake and swimming are strictly prohibited to protect water quality. * Construction: The dam was built between 1951 and 1964. Its construction was a feat of engineering, as it is the only pier dam in the Czech Republic. This means that the dam consists of individual, vertical piers, giving it an unusual and striking appearance.

Overall, a nice round and not as strenuous as expected due to the few meters in altitude. Attention: on the last part (after the Green Graben) the given path runs on a slope through the undergrowth. Not recommendable! You can reach your destination more safely by taking a detour along a larger path and a small road.
