  • maximum dam thickness at the base is 47 metres thinning to 6 metres thick at the top
  • 1,510,000 cubic metres of cement were used to build the dam
  • the maximum level reached by water is 1,969 m a.s.l.
  • 105 million cubic metre is the dam capacity.

The dam exterior is always open to the public, but upon reservation it is possible to enjoy a guided tour inside in the period from May to September. The dam can be inspected on several levels that lower even under the lake waters and are connected by stairs and an elevator. Numerous machines and equipment tied to dam operations and safety controls are to be found inside.
