Lipno Reservoir

Lipno lake - the largest water surface in the Czech Republic

The Lipno Reservoir was built on the Vltava River between 1950 and 1959. During the construction, the favourable natural environment was taken advantage of, in particular the landscape character and the fall of the Vltava. Plans for regulation and energetic exploitation of the Vltava had been produced since the end of the 19th century. The Lipno Hydroelectric Power Plant was constructed as the fourth oldest reservoir of the Vltava Cascade, being the first one counted downstream. Lipno is the largest water surface in the Czech Republic, which is of essential economic importance: it is a water reservoir, constitutes protection against floods, is an important source for the generation of power and forms an attractive environment for recreation and the development of tourism.

Lipno lake - parts

The reservoir was built in two parts: Lipno I – the main reservoir, and Lipno II further down stream – the equalising reservoir. The power plant is located in an artificial cave 171 metres under ground. The generation of power is provided by two Francis turbines and the spill water flows through a 3.6 km long underground discharge tunnel to the equalising reservoir, which houses a Kaplan turbine. It is possible to visit the power plant.

Lipno Reservoir - basic specifications

  • elevation of the surface: 725.6 m above sea level
  • length of the reservoir: 44 km (some sources say 40 or 48 km)
  • width at the widest point (Černá v Pošumaví): 10 km (some sources say 16 km)
  • average depth: 6.5 metres
  • maximum depth: 21.5 metres
  • area: 48.7 km²
  • capacity: 306 million m³
  • drainage area: 950.56 km²

(Note: Some of the data are different in available literature and on the Internet. This is probably because the length and width of the reservoir was measured at different water levels).
