Lake Baikal is a rift lake and the deepest lake in the world. It is situated in southern Siberia, Russia, between the federal subjects of Irkutsk Oblast to the northwest and the Republic of Buryatia to the southeast. At 31,722 km2 (12,248 sq mi)—slightly larger than Belgium—Lake Baikal is the world’s seventh-largest lake by surface area, as well as the second-largest lake in Eurasia after the Caspian Sea. However, because it is also the deepest lake, with a maximum depth of 1,642 metres (5,387 feet), Lake Baikal is the world’s largest freshwater lake by volume, containing 23,615.39 km3 (5,670 cu mi) of water or 22–23% of the world’s fresh surface water, more than all of the North American Great Lakes combined. It is also the world’s oldest lake at 25–30 million years, and among the clearest. It is estimated that the lake contains around 19% of the unfrozen fresh water on the planet. Lake Baikal is home to thousands of species of plants and animals, many of them endemic to the region. It is also home to Buryat tribes, who raise goats, camels, cattle, sheep, and horses, on the eastern side of the lake within Buryatia, where the mean temperature varies from a winter minimum of ?19 °C (?2 °F) to a summer maximum of 14 °C (57 °F). The region to the east of Lake Baikal is referred to as Transbaikalia or as the Transbaikal, and the loosely defined region around the lake itself is sometimes known as Baikalia. UNESCO declared Baikal a World Heritage Site in 1996.
