Novosibirsk Reservoir

BW

The Novosibirsk Reservoir (Russian Новосибирское водохранилище, Nowosibirskoje Wodochranilischtsche ), popularly Obskoje Morje ( Обское море, Ob - Sea) called, is an approximately 1082 km ² large reservoir near Novosibirsk on the Ob in Novosibirsk Oblast and Altai ( Siberia) in the Asian part Russia.

Geographical location

The Novosibirsk reservoir extends in the southeast part of the Novosibirsk Oblast and with its Southwest foothills in the north- western part of the Altai region. He averages about 90 km southwest of the city of Novosibirsk million with southern districts at the reservoir. Among other towns also Berdsk located on the banks; located near Iskitim. Is Bathed the reservoir from the Ob, one of the longest rivers in the world. Among the leading- rivers include the eastern Sawjalowo the Karakan and the northeastern Berdsk the Berdbucht flowing through Berd.

Reservoir

The Novosibirsk reservoir is about 1082 km ². He is a maximum of about 185 km long and 18 km wide and is located at 113 m altitude. On average, it is 8.2 m and maximum 25 m deep. Its capacity is 4.4 km ³ of storage space and 8.8 km ³ total storage space, its catchment area is 227.5 thousand km ² and its mean annual runoff is 54.5 km ³. Due to the investment of the dam approximately 284 km ² of arable land were flooded in the river valley, with 8,225 buildings had to be demolished or relocated. On the shore there are numerous beaches and tourist facilities.

Dam

The dam is located in Novosibirsk city, approximately 20 km south-southeast of the city center. It consists of overflow dam, ship lock, with access channel, left (318 m long) and right embankment ( 4,961 m) and right dam ( 1,023 m).

Spanning the dam road connects the district Schljusy ( Шлюзы, literally locks) and ObGES ( ОбьГЭС, literally: Whether hydroelectric power plant ). Just east of the dam is located Novosibirsk Akademgorodok Wissenschaftlerort.

Hydroelectric power station

The hydroelectric power plant, which has been integrated into the dam is 223.6 m long. His seven turbines á 65 MW supply a total of 455 MW. In mid-year the plant produced 1,687 million kWh of electrical energy. The maximum outflow of 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

First ideas to build a hydroelectric power plant to supply power from Novosibirsk, formed at the beginning of the 20th century, and first plans to build along smaller rivers were discarded. 1950 a working group was established in 1951 confirmed the project for the construction of the hydroelectric plant on the Ob. Construction began in 1953, in 1956 the Ob was dammed. From 1957, the series were taken after the seven generators in operation. 1961, the building was officially completed. Was projected the construction of the Institute " Lengidroprojekt ". In 1972, the performance of the generators has been increased from 400 to 455 MW.

Environmental problems

The damming of the Ob had significant environmental problems. Erosion, due annihilated (flooded ) forests, floods and flood occurred. The population of some fish species in Whether increased after construction of the dam dramatically.
