'''Lake Baikal''' ({{lang-ru|о́зеро Байка́л ''Ozero Baykal''}}, {{pronounced|ˈozʲɪrə bʌjˈkɑl}}, {{lang-bxr|Байгал нуур ''Baygal nuur''}}) sits in Southern [[Siberia]] in [[Russia]], located between [[Irkutsk Oblast]] to the northwest and the [[Buryatia|Buryat Republic]] to the southeast, near the city of [[Irkutsk]]. Also known as the "Blue Eye of Siberia," it contains more water than all the North American [[Great Lakes]] combined. At {{m to ft|1637|precision=0}}, Lake Baikal constitutes the deepest lake in the world, and the [[List of lakes by volume|largest freshwater lake]] in the world by volume, holding approximately 20 percent of the world's total surface fresh water.

Like [[Lake Tanganyika]], Lake Baikal formed in an ancient [[rift valley]] and  therefore has a long, and crescent shape with a surface area (31,500 km²) less than half that of [[Lake Superior]] or [[Lake Victoria]]. Baikal serves as home to more than 1,700 species of plants and animals, two thirds found only in the lake zone. [[UNESCO]] designated Lake Baikal a [[World Heritage Site]] in 1996. At more than 25 million years old, it has been declared the oldest lake in the world. The successful dive of [[Mir-1]] and [[Mir-2]] [[mini-submarine]]s to the deepest place in Baikal on 29 July 2008, at over one mile, has opened the prospect of new discoveries of ancient lake life.
  
'''Lake Baikal''' ([[Russian language|Russian]]: ''Байка́л'', [[International Phonetic Alphabet|pronounced]] {{IPA|['ozʲɪrə bʌj'kɑl]}}; [[Buryat language|Buryat]] and [[Mongol language|Mongol]]: ''Dalai-Nor'') lies in Southern [[Siberia]] in [[Russia]] between [[Irkutsk Oblast]] to the northwest and [[Buryatia]] to the southeast near the city of [[Irkutsk]]. The origin of the name Baikal comes from ''Baigal'' or Байгал which is translated from the [[Mongolian language]] as "[[nature]]".  It is also known as the ''Blue Eye of Siberia''.<ref>{{cite web

While known as the "North Sea" in historical Chinese texts, Lake Baikal had been located in the then Xionu territory. Lake Baikal had been out of the public eye until the Russian government built the [[Trans-Siberian railway]] between 1896 and 1902. The scenic loop encircling Lake Baikal needed 200&nbsp;bridges and 33&nbsp;tunnels. As under construction, [[Fedor Kirillovich Drizhenko|F.K. Drizhenko]] headed a hydrogeographical expedition that produced the first detailed atlas of the contours of Baikal's depths. The atlas demonstrated that Lake Baikal has more water than all of [[North America]]'s [[Great Lakes]] combined—{{km3 to mi3|23600}}, about one fifth of the total fresh water on the earth.<ref name=facts>[https://lakebaikal.org/lake-baikal-facts/ Lake Baikal Facts] ''Lake Baikal''.

At {{km to mi|636}} long and {{km to mi|79}} wide, Lake Baikal has the largest surface area of any freshwater lake in [[Asia]] ([[1 E10 m²|31,494 km²]]), constituting the deepest lake in the world (1,637 meters, previously measured at 1,620 meters). The bottom of the lake measures 1,285 meters below sea level, but below that lies some {{km to mi|7|precision=1}} of [[sediment]], placing the rift floor some 8–9 kilometers (more than 5 miles) below the surface: the deepest continental [[rift]] on [[Earth]].<ref name="oddities"/> In geological terms, the rift, young and active, widens about two centimeters per year. The [[fault zone]] experiences frequent [[seismic activity]]. New [[hot springs]] appear in the area and notable [[earthquake]]s happen every few years.

Its age, estimated at [[1 E14 s|25–30 million years]], makes it one of the most ancient lakes in [[geology|geological]] history. Unique among large, high-latitude lakes, its [[sediment]]s have been unscoured by overriding continental ice sheets. U.S. and Russian studies of core sediment in the 1990s provide a detailed record of climatic variation over the past 250,000 years.

The lake is completely surrounded by mountains, with the [[Baikal Mountains]] on the north shore and the [[taiga]] technically protected as a national park. It contains 22 islands; the largest, [[Olkhon]], measures {{km to mi|72}} long. The lake has as many as three hundred and thirty inflowing [[river]]s, the main ones draining directly into Baikal include the [[Selenga River]], the [[Barguzin River]], the [[Upper Angara River]], the [[Turka River]], the [[Sarma River]] and the [[Snezhnaya River]]. The [[Angara River]] serves as its single drainage outlet.<ref name=facts/> Despite its great depth, the lake's waters have excellent oxygenation throughout the water column compared to the [[Stratification (water)|stratification]] that occurs in such bodies of water as [[Lake Tanganyika]] and the [[Black Sea]].
Very little was known about Lake Baikal until the [[Trans-Siberian railway]] was built between 1896 and 1902. The scenic loop encircling Lake Baikal needed 200 bridges and 33 tunnels. As this railway was being built, a large hydrogeographical expedition headed by [[Fedor Kirillovich Drizhenko|F.K. Drizhenko]] produced the first detailed atlas of the contours of Baikal's depths. The atlas demonstrated that Lake Baikal has as much water as all of [[North America]]'s [[Great Lakes]] combined — 23,600 km³, about one fifth of the total fresh water on the earth. However, in surface area, it is exceeded by the much shallower Great Lakes [[Lake Superior|Superior]], [[Lake Huron|Huron]] and [[Lake Michigan|Michigan]], as well as by the relatively shallow [[Lake Victoria]] in [[East Africa]].<ref>{{cite web

At 636 [[kilometre]]s long and 80 km wide, Lake Baikal has the largest surface area of any freshwater lake in [[Asia]] ([[1 E10 m²|31,494 km²]]) and is the deepest lake in the world (1637 metres, previously measured at 1620 metres). The bottom of the lake is 1285 metres below sea level, but below this lies some 7 km (4 miles) of [[sediment]], placing the rift floor some 8–9 km (more than 5 miles) below the surface: the deepest continental [[rift]] on [[Earth]]. In geological terms, the rift is young and active — it widens about 2 centimeters per year. The fault zone is also seismically active: there are hot springs in the area and notable earthquakes every few years. It drains into the [[Angara]] tributary of the [[Yenisei]].

The lake is completely surrounded by mountains. the [[Baikal Mountains]] on the north shore and [[taiga]], is technically protected as a national park and contains 22 small islands, the largest, [[Olkhon]] (also spelled 'Olchon'), being 72km long. The lake is fed by some 300 inflowing rivers, the six main ones being [[Selenga]], the source of some of Baikal's pollution, [[Chikoy]], [[Khiloh]], [[Uda River, Buryatia|Uda]], [[Barguzin]] and [[Upper Angara River]], and is drained through a single outlet, the [[Angara River]].
+
The extent of [[biodiversity]] present in Lake Baikal surpasses all except a few lakes. Lake Baikal hosts over 2,500 species of plants and varieties of animals, with over 80 percent of animals [[Endemic (ecology)|endemic]].  The [[Baikal Seal]] or [[nerpa]] ''(Phoca sibirica)'', found throughout Lake Baikal, constitutes one of only three entirely freshwater [[phocid|seal]] species in the world, the other being the two subspecies of freshwater [[Ringed Seal]]. The [[omul]] ''(Coregonus autumnalis migratorius),'' a smallish endemic [[salmonid]], may be the most important local species.<ref>Deborah Byrd,  Lake Baikal: Earth’s deepest, oldest lake ''EarthSky'', June 4, 2019.</ref> Local people catch and [[Smoking (food)|smoke]] the salmonid, selling it widely in markets around the lake.
  
Despite its great depth, the lake's waters are well-mixed and well-oxygenated throughout the water column compared to the [[stratification]] that occurs in such bodies of water as [[Lake Tanganyika]] and the [[Black Sea]].  
+
The two species of [[golomyanka]] or Baikal oil fish (''Comephorus baicalensis'' and ''C. dybowskii'') have earned special note. Those long-finned, translucent fish, living in depths of 700 to 1600 feet, serve as the primary prey for the Baikal seal, representing the largest fish biomass in the lake. The Baikal oil fish have become famous for disintegrating into a pool of oil and bones when withdrawn rapidly from the high pressures of the deep water. The Baikal [[Grayling (genus)|grayling]] ''(Thymallus arcticus baicalensis),'' a fast swimming [[salmonid]] popular among anglers, and the [[Baikal sturgeon]] ''(Asipenser baerri baicalensis)'' both constitute important endemic species with commercial value.
  
Despite muted protests, a wood pulp and cellulose processing plant was built at the south end of the lake (at Baikalsk). The plant still pours industrial effluent into Baikal's waters.  The overall impacts of watershed pollution on Baikal and similar watersheds are studied annually by the Tahoe-Baikal Institute,<ref>{{cite web

The extent of [[biodiversity]] present in Lake Baikal is equaled by few other lakes. Lake Baikal hosts 1085 species of plants and 1550 species and varieties of animals. Over 80% of animals are  [[Endemic (ecology)|endemic]]. The [[Baikal Seal]] (''Phoca sibirica''), the only mammal living in the lake, is found throughout the whole area of the lake but nowhere else.  
+
Several organizations have been conducting natural research projects on Lake Baikal, mostly governmental or groups associated with governmental organizations.  
  
Of note is an endemic subspecies of the [[omul]] fish (''Coregonus autumnalis migratorius''). It is fished, [[Smoking (food)|smoked]], and sold in markets around the lake. For many travellers on the [[Trans-Siberian railway]], purchasing smoked omul is one of the highlights on the long journey.

In July 2008, Russia sent two small submersibles, Mir-1 and Mir-2, to descend 1,592 m (5,223 ft) to the bottom of Lake Baikal to conduct geological and biological tests on its unique ecosystem. Russian scientist and federal politician [[Artur Chilingarov]], the leader of the mission, took part in the Mir dives.<ref>[https://sputniknews.com/russia/20080729115171121/ Russian mini-subs surface after record dive in Siberian lake] ''Novosti'', July 29, 2008 (in English) Retrieved January 28, 2020.</ref>

Investors from the [[tourism|tourist industry]] have been drawn to Lake Baikal since energy revenues sparked an economic boom. That represents an economic benefit to local residents but potential harm to the Lake Baikal site.

Lake Baikal (Russian: о́зеро Байка́л Ozero Baykal, pronounced [ˈozʲɪrə bʌjˈkɑl], Buryat: Байгал нуур Baygal nuur) sits in Southern Siberia in Russia, located between Irkutsk Oblast to the northwest and the Buryat Republic to the southeast, near the city of Irkutsk. Also known as the "Blue Eye of Siberia," it contains more water than all the North American Great Lakes combined. At 1,637 meters (5,371 ft), Lake Baikal constitutes the deepest lake in the world, and the largest freshwater lake in the world by volume, holding approximately 20 percent of the world's total surface fresh water.

Like Lake Tanganyika, Lake Baikal formed in an ancient rift valley and therefore has a long, and crescent shape with a surface area (31,500 km²) less than half that of Lake Superior or Lake Victoria. Baikal serves as home to more than 1,700 species of plants and animals, two thirds found only in the lake zone. UNESCO designated Lake Baikal a World Heritage Site in 1996. At more than 25 million years old, it has been declared the oldest lake in the world. The successful dive of Mir-1 and Mir-2 mini-submarines to the deepest place in Baikal on 29 July 2008, at over one mile, has opened the prospect of new discoveries of ancient lake life.

Geography and hydrography

The peninsula of Svyatoy Nos.

While known as the "North Sea" in historical Chinese texts, Lake Baikal had been located in the then Xionu territory. Lake Baikal had been out of the public eye until the Russian government built the Trans-Siberian railway between 1896 and 1902. The scenic loop encircling Lake Baikal needed 200 bridges and 33 tunnels. As under construction, F.K. Drizhenko headed a hydrogeographical expedition that produced the first detailed atlas of the contours of Baikal's depths. The atlas demonstrated that Lake Baikal has more water than all of North America's Great Lakes combined—23,600 cubic kilometers (5,662.4 cu mi), about one fifth of the total fresh water on the earth.[1] In surface area, the much shallower Great Lakes Superior, Huron and Michigan in North America, as well as by the relatively shallow Lake Victoria in East Africa exceeded it. Known as the "Galápagos of Russia," its age and isolation have produced some of the world's richest and most unusual freshwater fauna of exceptional value to evolutionary science.[2]

Lake Baikal lies in a rift valley created by the Baikal Rift Zone where the crust of the earth pulls apart.[3]

The Yenisei River basin, Lake Baikal, and the settlements of Dikson, Dudinka, Turukhansk, Krasnoyarsk, Irkutsk.

At 636 kilometers (395.2 mi) long and 79 kilometers (49.1 mi) wide, Lake Baikal has the largest surface area of any freshwater lake in Asia (31,494 km²), constituting the deepest lake in the world (1,637 meters, previously measured at 1,620 meters). The bottom of the lake measures 1,285 meters below sea level, but below that lies some 7 kilometers (4.3 mi) of sediment, placing the rift floor some 8–9 kilometers (more than 5 miles) below the surface: the deepest continental rift on Earth.[3] In geological terms, the rift, young and active, widens about two centimeters per year. The fault zone experiences frequent seismic activity. New hot springs appear in the area and notable earthquakes happen every few years. It drains into the Angara tributary of the Yenisei.

Did you know?
Lake Baikal in Southern Siberia, Russia is the deepest lake in the world

Its age, estimated at 25–30 million years, makes it one of the most ancient lakes in geological history. Unique among large, high-latitude lakes, its sediments have been unscoured by overriding continental ice sheets. U.S. and Russian studies of core sediment in the 1990s provide a detailed record of climatic variation over the past 250,000 years. Geologists expect longer and deeper sediment cores in the near future. Lake Baikal has been confirmed as the only fresh water lake with direct and indirect evidence of gas hydrates existing.[4]

The lake is completely surrounded by mountains, with the Baikal Mountains on the north shore and the taiga technically protected as a national park. It contains 22 islands; the largest, Olkhon, measures 72 kilometers (44.7 mi) long. The lake has as many as three hundred and thirty inflowing rivers, the main ones draining directly into Baikal include the Selenga River, the Barguzin River, the Upper Angara River, the Turka River, the Sarma River and the Snezhnaya River. The Angara River serves as its single drainage outlet.[1] Despite its great depth, the lake's waters have excellent oxygenation throughout the water column compared to the stratification that occurs in such bodies of water as Lake Tanganyika and the Black Sea.

Olkhon, the largest island in Lake Baikal, constitutes the fourth-largest lake-bound island in the world.

Wildlife

Omul Fish at the Listvyanka market.

The extent of biodiversity present in Lake Baikal surpasses all except a few lakes. Lake Baikal hosts over 2,500 species of plants and varieties of animals, with over 80 percent of animals endemic. The Baikal Seal or nerpa (Phoca sibirica), found throughout Lake Baikal, constitutes one of only three entirely freshwater seal species in the world, the other being the two subspecies of freshwater Ringed Seal. The omul (Coregonus autumnalis migratorius), a smallish endemic salmonid, may be the most important local species.[5] Local people catch and smoke the salmonid, selling it widely in markets around the lake.

The two species of golomyanka or Baikal oil fish (Comephorus baicalensis and C. dybowskii) have earned special note. Those long-finned, translucent fish, living in depths of 700 to 1600 feet, serve as the primary prey for the Baikal seal, representing the largest fish biomass in the lake. The Baikal oil fish have become famous for disintegrating into a pool of oil and bones when withdrawn rapidly from the high pressures of the deep water. The Baikal grayling (Thymallus arcticus baicalensis), a fast swimming salmonid popular among anglers, and the Baikal sturgeon (Asipenser baerri baicalensis) both constitute important endemic species with commercial value.

Hunters commonly track and shoot bear and deer along Baikal shores.

Research

Ice cover survey on the lake

Several organizations have been conducting natural research projects on Lake Baikal, mostly governmental or groups associated with governmental organizations.

In July 2008, Russia sent two small submersibles, Mir-1 and Mir-2, to descend 1,592 m (5,223 ft) to the bottom of Lake Baikal to conduct geological and biological tests on its unique ecosystem. Russian scientist and federal politician Artur Chilingarov, the leader of the mission, took part in the Mir dives.[6]

Environmental concerns

The lake in the winter, as seen from the tourist resort of Listvyanka. The ice becomes thick enough to support pedestrians and snowmobiles.

Baykalsk pulp and paper mill

The lake in the summer, as seen from Bolshiye Koty on the southwest shore.

Industrialists constructed the Baykalsk Pulp and Paper Mill (BPPM) in 1966 on the shore line. The BPPM bleaches its paper with chlorine, discharging the waste into Baikal. Despite numerous protests, the BPPM still operates. Environmental activists endeavor to make the pollution less harmful rather than end BPPM's production, since a plant shutdown would end jobs vital to the local economy.

East Siberia-Pacific Ocean Oil Pipeline

Russian oil pipelines state company Transneft planned to build a trunk pipeline that would have come within 800 meters (2,620 ft) of the lake shore in a zone of substantial seismic activity. Environmental activists in Russia, Greenpeace, Baikal pipeline opposition, and local citizens strongly opposed these plans, because an accidental oil spill would cause significant damage to the fragile lake environment. Russian president Vladimir Putin intervened, ordering the company to consider an alternative route 40 kilometers (24.9 mi) to the north to avoid such ecological risks. [7] Transneft agreed to alter its plans, moving the pipeline away from Lake Baikal. Work began on the pipeline two days after President Putin agreed to changing the route away from Lake Baikal.[8]

Uranium Enrichment Center

In 2006, the Russian Government announced plans to build the world's first International Uranium Enrichment Center at an existing nuclear facility in Angarsk, 95 kilometers from the lake's shores. Critics argue that could lead to a disaster for the region, urging the Government to reconsider.[9]

The Uranium Enrichment Center was opened in Angarsk in December, 2010.[10]

Tourism

Investors from the tourist industry have been drawn to Lake Baikal since energy revenues sparked an economic boom. That represents an economic benefit to local residents but potential harm to the Lake Baikal site. Viktor Grigorov, owner of the Grand Baikal in Irkutsk, a city with a population of about 600.000, numbers among the investors who planned to build three hotels, creating 570 jobs. In 2007, the Russian government declared the Baikal region a special economic zone. The popular resort of Listvyanka has a seven-story Hotel Mayak. Rosatom plans to build a laboratory in Baikal, in conjunction with an international uranium plant and to invest $2.5bn in the region and create 2,000 jobs in the city of Angarsk.[11] The harmful toll of hotels in the World Heritage site, Lake Baikal, looms as an environmental threat.
