The Lake Baikal in south-east Siberia contains 20% of all fresh running water on the planet. The Lake Baikal was formed as an ancient rift valley, having the typical long crescent shape with a surface area of 31'722 square kilometres. It is 636 km long and 79 km wide and is the deepest lake in the world at 1'642 m.

Soviet Union 1966, 50th anniversary of Barguzinsky State Biosphere Nature Reserve.
The Barguzinskiy Reserve was established on 29 December 1916 (11 January 1917) to research, conserve and restore the sable. It is situated on the north-eastern shore of the Lake Baikal, on the western slopes of the Barguzin Range. Its area is 366,870 hectares. The Barguzinskiy Reserve is the first state natural reserve in Russia. There were only 20–30 specimens in the reserve at the time of its creation, whereas now there are 1–2 specimens per 1 sq. km. All natural objects and complexes, such as minerals, waters, soils, wildlife, air basin and vegetation, are subject to preservation and study. It is one of the few places where primeval forests still thrive.
The Barguzinskiy Reserve has been a part of UNESCO World Network of Biosphere Reserves since 1986. It is a sign of an international recognition of its efforts in sable research and restoration, as well as in preserving natural biodiversity of the Baikal Region. The Reserve territory was wholly included into the Lake Baikal UNESCO World Heritage Site in 1996.
