Sayano-Shushenskoe Reservoir

Sent by Tanya from Krasnoyarsk Krai in Russia.

The Sayano-Shushenskaya Dam (Russian: Сая́но-Шу́шенская гидроэлектроста́нция, Sayano-Shushenskaya Hydroelektrostantsiya) is located on the Yenisei River, near Sayanogorsk in Khakassia, Russia. It is the largest power plant in Russia and the 12th-largest hydroelectric plant in the world, by average power generation. The full legal name of the power plant, OJSC [Open Joint-Stock Society] P. S. Neporozhny Sayano-Shushenskaya HPP [hydro power plant], refers to the Soviet era Minister of Energy and Electrification Pyotr Neporozhny. As of 2009 the head of the power plant was Valery Kyari.

The plant is operated by RusHydro. As of 2009, it was the largest power plant in Russia and the world's sixth-largest hydroelectric plant by average power generation. It provides more than a quarter of RusHydro's generation capacity. The plant operated ten type РО-230/833-0-677 hydro turbines manufactured at the Leningradsky Metallichesky Zavod, each with a capacity of 640 MW at 194-metre (636 ft) head. The total installed capacity of the plant is 6,400 MW; its average annual production is 23.5 TWh, which peaked in 2021 at 29.4 TWh.

The station's constructions include the dam, a power plant building located near the dam, and an additional spillway which is under construction. The arch-gravity dam is 242 metres (794 ft) high. It has a crest length of 1,066 metres (3,497 ft), crest width of 25 metres (82 ft), base width of 105.7 metres (347 ft) and maximum head of 220 metres (720 ft). It consists of a solid left-bank dam 246.1 metres (807 ft) long, a power dam 331.8 metres (1,089 ft) long, a spillway dam 189.6 metres (622 ft) long and a solid right-bank dam 298.5 metres (979 ft) long. It is by far the larger of only two gravity-arch dams in Russia. Water pressure for the dam is approximately 30 million tons, of which 60% is neutralized by the dam's own weight and 40% is carried to rock on the bank

The dam is constructed to "safely" withstand earthquakes up to 8 on the Richter scale, and was recorded by the Guinness Book of World Records for the strongest construction of its type (read more).

This is from Wikipedia : The Chuya Steppe in the Siberian Altai Mountains is a depression formed by tectonic movement of major faults in the Earths crust. The name 'Chuya Steppe' comes from the large river which runs through the steppe, the Chuya River.

Russia - Lake Baikal (1)

Lake Baikal in south-east Siberia, the deepest lake in the world at 1,700 m, contains 20% of all fresh running water on the planet, making it the single largest reservoir. The lake contains an outstanding variety of endemic flora and fauna, of exceptional value to evolutionary science. It is also surrounded by a system of protected areas that have high scenic and other natural values. The basin supports a variety of plant and animal species, a number being endemic; the most notable of which is the Baikal seal, a uniquely freshwater species. The great variety of plants in the basin is determined by its climatic asymmetry: the western part is occupied by light coniferous forests and mountain steppes; in the eastern part pine forests predominate; and the north is covered by deciduous forests. The formation of the geological structures in the basin took place during the Palaeozoic, Mesozoic and Cenozoic eras and there are a number of significant geological features. Various tectonic forces are still ongoing, as evidenced in recent thermal vents in the depths of the lake.

The lake itself is the centrepiece of the site and its largely unseen underwater features are the core of its value to both science and conservation. Baikal is one of the most biodiverse lakes on Earth, with 1,340 species of animal (745 endemic) and 570 species of plant (150 endemic). In the forests surrounding the lake there are an additional 10 threatened species along with the full complement of typical boreal species. The evolution of aquatic life that has taken place over this long period has resulted in an exceptionally unique and endemic fauna and flora. As the 'Galápagos of Russia', the lake is of exceptional value to evolutionary science.

The landscape surrounding the lake basin, with its mountains, boreal forests, tundra, lakes, islands and steppes, is exceptionally picturesque. The Baikal region has some 1,200 historical, archaeological and cultural monuments of which 1,000 have state protection. A number of these are considered sacred. There is also a mix of distinctive cultures in the region and an interesting human history.

However, there are serious threats to the biotic communities at Lake Baikal and there is a danger that its unique ecosystem properties could be lost. Various steps are being taken to address these issues of integrity with strong support from all levels of government and the Russian public. (Source)
