Lakes and dams Jizerské hory

The Vodní nádrž Souš reservoir is situated on the Černá Desná river above the town of Desná in the Liberecký kraj region. The road along the Soušská přehrada dam connects the Frýdlantsko and Tanvaldsko regions on the other side of the Jizerské hory mountains; however, it should be noted that the road is not maintained in winter and is closed. In the summer months, however, the area around the reservoir invites visitors for trips.

A settlement of the same name, which even featured a glassworks, stood on the site of today's Souš reservoir as early as the 18th century. However, the settlement had to give way to the construction of two dams—one on the Bílá Desná and the other on the Černá Desná—connected by a tunnel. The dams were built between 1911 and 1915 as flood protection for the Jizerské hory mountains. However, the dam on the Bílá Desná burst just 10 months after its completion in 1916, sweeping away 100 houses and claiming 65 lives. After this disaster, local residents insisted on draining Souš and only refilling it after a thorough inspection of the reservoir's condition to ensure that such a catastrophe would not happen again. The Souš dam was therefore only refilled after reconstruction between 1924 and 1927. In the 1970s, the dam originally served, among other things, for recreation, but since 1973 it has served as a drinking water reservoir for the Tanvaldsko and Jablonecko regions. Fishing and swimming are therefore understandably prohibited, and the area around the Souš reservoir is strictly protected.

The Souš dam covers an area of nearly 86 hectares. Its embankment is earth-fill, and the concrete wall reaches a depth of 8 metres. A 19.1-metre-high tower structure stands in the reservoir, used for water abstraction for water supply purposes. As this is a drinking water reservoir, a water treatment plant stands on its right bank, where water hardness is reduced and its oxidisability and colour are adjusted. Only once treated in this way does the water continue through pipes to the water reservoir in Tanvald and from there to Jablonec nad Nisou.
