The Qapshaghai Dam ( Kazakh Қапшағай бөгені ; also Kapshaghai Dam (derived from Russian)) is located north of Almaty , the former capital of Kazakhstan , near the city of Qapshaghai (Russian Капшагай ) on the Ili River .
The associated reservoir (Qapschaghai Lake) with an approximate size of 110 km × 30 km has a water surface of 1847 km² and a storage space of 28,140 million m³. It supplies Almaty with water and, after the Buchtarma reservoir, is one of the two largest reservoirs in Kazakhstan. Electricity is generated in a hydropower plant.
The dam has two barricades, two dams , one with a length of 470 m and one with a length of 370 m. The length of the crown is given elsewhere as 1900 m. The greatest height is 56 m, but 35.41 m and 52 m are also mentioned as alternatives. Further characteristics of the two structures are:
- Length: 470 m, height: 50 m; Base width: 450 m, building material: ash sand
- Length: 370 m, height: 56 m, base width: 270 m, building material: sandy soil
In 1965, construction of the hydropower plant began. On September 29, 1969, the Ili was cordoned off for the first time and in May 1970 the filling of the reservoir began. The first turbine started work on December 22, 1970, the fourth on December 22, 1971. The last construction work was completed in 1980. The four turbines and generators deliver an output of 4 × 91 MW = 364 MW. (Elsewhere, 4 × 108.5 MW = 434 MW is spoken of.)
There are bathing beaches on the lake, which are visited, for example, by excursionists from Almaty.
