So huge that it is often erroneous for a sea, Russia’s Lake Baikal is the deepest and oldest lake in the world, and the biggest freshwater lake by size. famed for its crystal clear waters and sole wildlife, the lake is under threat by pollution, poaching and growth.
More than 5,000 ft . profound (1637m) at its most deep, with another four-mile-thick layer of residue further down, the lake’s cold, oxygen-rich waters teem with bizarre life-forms.
One of those is the seals’ beloved food, the golomyanka, a pink, partly translucent fish which gives birth to live young. Geologists estimate that Lake Baikal formed somewhere 20-25 million years ago, during the Mesozoic.
bounded by mile-high snow-capped mountains, Lake Baikal still offers vistas of unrivalled beauty. The mountains are still a haven for wild animals, and the little villages are still outposts of tranquillity and self-reliance in the remote Siberian taiga, as the forest is called.
The lake is sited in Eastern Siberia, between Irkutsk Oblast to the northwest and Buryatia to the southeast. It is the planet’s deepest (1637m) and oldest lake, as well as its biggest body of freshwater, containing over one fifth of the world’s deliver. The origins of the name are unidentified, but several hypotheses are these: profound water (Yakut), rich lake (Turkic), rich fire (Mongolian), and northern sea (Chinese). Russians occasionally call the lake Baikal sea because of its size.
The lake’s geological pattern started around 20-25 million years ago, making it one of the oldest lakes in geological history and even at the present time its rift is continuing to widen 2cm a year. The first talk about of its name appeared in Chinese writings in 110 year B.C. as “Beihai” (Northern Sea). some cultures have appeared on its shores, including the Buryat.
Baikal Rivers and Island
Half the water fluid into the lake comes down the Selenga River in the southeast.
The rest comes from additional 330 other rivers and streams, many of them fluid from the surrounding mountains.
Lake Baikal’s single outlet is the Angara River, which flows westward from the lake’s southwestern end.
Lake Baikal has about 45 islands and islets, of which the two largest are Olkhon, about 270 square miles (700 square kilometres) in part, and Great Ushkany, which covers only about 3.6 square miles (9.4 square kilometres).
Olkhon is a area of forests and grasslands that supports deer, brown bears, and a wide range of birds.
Great Ushkany is rocky, the site of the biggest rookery of Baikal seals. Many of the other islands are little more than rocks, used as roosts by water birds.
Lake Baikal’s water is very clear because it contains very few mineral salts.
From the surface it is possible to observe objects 130 feet (40 meters) under!
This clearness is maintained by huge numbers of planktonic animals eating floating debris. In spite of its large deepness the water in the lake is well mixed, and oxygen is plentiful even in the bottom waters.
The water mass is a key issue to the climate of the lake’s banks. Winters are often milder, summers are chillier. Spring-time is late 10-15 days than the outer regions and fall is slightly long. The area is characteristic for sunshine longevity which is record-high for the whole of Russia. Exact traits are added to the climate of the Baikal by winds: barguzin, sarma, verkhovik, kultuk. It is a ordinary thinking that the Baikal is most excellent for visit in July, when temperatures and winds arrive at favourable condition. The water in summer is cold, normally +8..+9C and can reach +15C in bays. It’s so pellucid that one can see the bottom 40m down.
