The Novosibirsk Reservoir ( Russian Новосибирское водохранилище , Nowosibirskoje Wodochranilischtsche), in the vernacular Obskoje Morje ( море Обское , Ob-Sea), is an approximately 1,082 km² large artificial lake near Novosibirsk on Whether in the Novosibirsk Oblast and Altai ( Siberia ) in the Asian part Of Russia .
Geographical location
The Novosibirsk Reservoir extends in the southeast part of the Novosibirsk Oblast and with its southwest foothills in the northwest part of the Altai region. It is on average around 90 km southwest of the metropolis of Novosibirsk with its southern districts on the reservoir. Berdsk is also located on the bank, along with other localities ; Iskitim is nearby . The reservoir is traversed by the Ob , one of the longest rivers on earth . Among the leading-flowing waters include the eastern Sawjalowo the Karakan and the northeastern Berdsk of the Berdbucht flowing through Berd .
Reservoir
The Novosibirsk reservoir is about 1,082 km². It is a maximum of 185 km long and 18 km wide and is 113 m high. On average it is 8.2 m and a maximum of 25 m deep. Its capacity is 4.4 km³ storage space and 8.8 km³ total storage space , its catchment area is 227,500 km² and its mean annual discharge is 54.5 km³. Due to the construction of the reservoir, around 284 km² of arable land in the river valley was flooded, with 8,225 buildings having to be demolished or relocated. There are numerous beaches and tourist facilities on the shore.
dam
The dam is located in the Novosibirsk urban area, around 20 km south-southeast of the city center. It consists of an overflow dam, ship lock with access channel, left (318 m long) and right embankment (4,961 m) and right dam (1,023 m).
The road leading over the dam connects the districts of Schljusy ( Шлюзы, literally: locks) and ObGES ( ОбьГЭС, literally: Ob hydroelectric power station). A little to the east of the dam is Novosibirsk's academic site, Akademgorodok .
Hydroelectric power plant
The hydropower plant that was integrated into the dam is 223.6 m long. Its 7 turbines of 65 MW each deliver a total of 455 MW. The power plant produces 1,687 million kWh of electrical energy on average over the year . The maximum discharge over the generators (0.1%) is 15,900 m³ / s, the length of the wall under pressure is 5.33 km and the maximum static pressure is 19.6 m.
history
The first ideas to build a hydropower plant to supply electricity to Novosibirsk arose at the beginning of the 20th century, and the first plans to build along smaller rivers were rejected. A working group was founded in 1950 and the project for the construction of the hydroelectric power station on the Ob was confirmed in 1951. Construction began in 1953, from 1956 the Ob was dammed. From 1957 onwards, the seven generating sets were put into operation one after the other. Construction was officially completed in 1961. The building was planned by the "Lengidroprojekt" institute. In 1972 the output of the generators was increased from 400 to 455 MW.
environmental issues
The damming of the Ob resulted in considerable environmental problems. Erosion, due to destroyed (flooded) forests, floods and floods occurred. The population of some fish species in the Ob decreased dramatically after the dam was built.
