Construction
Start of preparation work in the construction occurred in 1974 and start of major construction works in 1976. The major capacity of Cierny Vah hydroelectric power plant was put into operation in 1981. The last turbogenerator was put into operation in 1982.
The water work has been built up above Svarin village. Backwater reaches Cierny Vah village. The upper reservoir interfere with the Turkova State natural reservation (it occupies approximately 14 ha of 137 ha total area). The complex is located in the region of Low Tatra National Park.
Major sites
Major sites of the water work are as follows: upper reservoir with dams, inlet site and inclined lift, lower reservoir dam, feeders, hydroelectric power plant, lower reservoir and waste canal.
Hydrologic and climatic conditions
The upper reservoir has no inflow in elevation above sea-level of 1130 – 1160 m n. B., where the temperature drops below 0o C during more than 130 days in a year (annual average 4.1 °C).

Structural solution and site description
The upper reservoir is located in table-land of irregular shape and this in massif, which divides valley of Čierny and Biely Vah in elevation of approximately 1,150 m above sea-level. The reservoir is of irregular tapered shape (level length maximum approximately 500 m). It is partially embedded in terrain. Natural rock environment of water and ground rock contact was replaced by artificial bitumen concrete environment of water impervious cover in the whole reservoir area. The reservoir is created by circumferential dams, which were bulked by excavation material. In regard to ground morphology and situation solution three separated dams had to be practically bind into rock massifs. The highest bank in coomb is high up to 75 m.
Sealing of slopes and reservoir bottom is solved as a bitumen concrete cover. Drainage layers are of crushed stones and potential nursling through AB – sealing is led out by tubes into the check corridor, where they can be monitored. Inlet site with hall and covered access to the upper station of the inclined lift are located in one edge of the upper reservoir. This improves conditions of reliable operation in hard climatic conditions. Access road 7,5 km road was built up in mountain landscape for accessing the upper reservoir during construction and operation.
