Background

Situated between Frunții Mountains and Ghițu mountains, the lake collects the Capra, Buda, and some other smaller rivers (Râul Doamnei, Cernatu, Vâlsan, Topolog, Valea lui Stan, and Limpedea), with a total flow of about 5.5 million L/s. The total surface of the lake is 3,930,000 sq m, 10.3 km in length, with a maximum width of 2.2 km in the Valea Lupului – Călugărița zone. Normal level or water retention is 830 metres above sea level (mdM).

The dam's construction took 5 and a half years. It required 42 km of tunnels, excavation of 1,768,000 cubic metres of hard rocks, out of which approximatively 1 million had to be extracted from underground, 930,000 cubic metres of concrete, out of which 400,000 cubic metres were underground and required the installation of 6,300 tons of electro-mechanical equipment.

When completed, it ranked 5th in Europe, and 9th in the world. In an average hydrological year it can generate approximately of 400 GWh/year. As of 2019, Vidraru Dam is the 16th tallest dam in Europe.

The Vidraru Hydro Power Plant has an installed capacity of 220 MW.
