The most interesting facts about lake Baikal


Baikal is not only the lake, but also a unique natural phenomenon. This reservoir is the object of endless interest from researchers, travellers and writers. About the lake written hundreds of books and filmed dozens of films. Everyone at school knows that this lake is a true heritage of not only Russia, but all over the world. In the end, Baikal – this is definitely the place where you should visit once in your life. And while we offer you 10 most interesting facts about this legendary lake.

10. Baikal is the deepest lake on our planet

And for zatravochka here's a well known fact, which is familiar from geography lessons. Indeed, Baikal is not only soda, but also the deepest of the lakes, located on the planet. In a kind of ranking the Baikal is in the lead, ahead of the predecessor (lake Tanganyika) by 172 meters. The deepest point of the great Russian of the reservoir is located at the level of 1642 meters below the horizon. For the first time this fact was established in 1983 in the study of the lake bottom, and then in 2002 during the compilation of a bathymetric map of lake Baikal's maximum depth was confirmed.

9. The lake is so large that it would fit about a hundred and Azov seas

Many people, especially the locals (recall that the object of our present interest is located in the Irkutsk region) tend to call the Baikal lake is not a lake but a sea. Well, it is quite reasonable, especially given the fact that lake Baikal's volume is much more of some bodies of water, nominally considered to be seas. The greatest contrast can also be seen if you compare the lake to the sea of Azov. The volumes of these two reservoirs differ nearly a hundred times! It is not surprising, given that the maximum depth of the Azov sea is only 13.5 metres. See paragraph above — yeah, that's our hundreds-and was.

8. Water temperature of the upper layers in the summer is only 8-10 degrees

However, with the seas (warm, of course, as we all love) Baikal can compete except that the volume of water. Because the lake is very cold. No joke, if during the period of freeze-up (and it lasts 4 months, from January to may), Baikal turns into a giant block of ice with just one ice-free area. Not warming up the water to a comfortable swimming temperature, even in mid-summer the temperature of the upper layers of the lake never rises above 10 degrees. Record high happened one day, when the water in some parts of lake Baikal warmed up to 23 degrees, but this was a big exception. Well, what do you want from a Siberian lake?

7. The lake is located in a seismically active area

The land on which lake (Baikal rift zone), there is a high seismic activity. There are regular earthquakes, however in most cases the power of the aftershocks no more than 2 points. However, there are cases most of these natural disasters. The most ambitious is considered Taganskoe earthquake, which occurred in 1862, when the tremors reached 10 points, and under water literally washed away as much as 200 square meters of land along with the residents. Over the past 100 years in the area of lake Baikal there were 6 earthquakes, the average power of which ranged from 9 points.

6. The water is so transparent that in some places you can see the bottom at depths of up to 38 meters

All used that water in our seas and lakes, quite frankly, not the most transparent. But the Baikal is absolutely not concerned. Here you can look through the water surface, though it is not at all. Indeed, in some areas in the spring, the visibility reaches 40 meters. Imagine you see the bottom or the rocks just as you see the asphalt from the roof of a 12-storey building. Truly fantastic! However, it is only in the first few weeks after freeze-up. In summer and autumn, as the origin in the warm (relatively of course) Baikal water numerous living organisms, the visibility starts to decrease and stops at around 8 metres, which in General is also very good.

5. Age is about 25 million years

In fact, the origin and age of lake Baikal is subject to controversy many scientists. Some people tend to believe that the lake is rather young and its depth of only 150 000 years, while others called the number to 35 million years, and others are not in a hurry with a great insights and stick to the traditional version. She says that the lake appeared about 25 million years ago. The man whose life expectancy of about a century, it is extremely difficult to estimate the time in this scale. However, even if we take at least 150 000 years, the lake Baikal is a unique lake because the water bodies of glacial origin, there are usually no more than 15 000 years.

4. Flow into Baikal 336 rivers, and follows only one river – Angara

This scientifically proven fact is taken traditionally at the basis of all kinds of legends about the lake. The most familiar story of the myth is as follows. Baikal had 336 sons, all of them nourished and filled father. But was the lake and the one and only daughter Angara, who fell in love with the Yenisei river and gave the one to his father's water. For this father cursed the daughter, leaving her in the Shaman rock (this rock is considered the beginning of the Angara). Judging from the current situation, the daughter is not stopped. Anyway, the Baikal from all sides is filled with 336 waterways, the largest of which are the Selenga, Barguzin and Kichera Tyya. Flows out of lake only the Hangar.

3. On the coast grow 700-year-old larch trees and 600-year-old cedars

Baikal is not only a giant lake, but no less ambitious a source of life for various species of flora and fauna. The territory of Baikal – one of the few places on the planet where truly virgin nature, untouched by man and is not inferior to him. The average age of the trees that dot the coast of the lake ranges from 6 centuries. Just think, how many things have happened during the lifetimes of these larches and cedars! And they continue their quiet life on the shores of lake Baikal, the father. By the way, even the cedars continue to bear fruit.

2. The water contains almost no minerals

However, that is enough to mark on the shore, because the main focus of research and conversations is the Baikal water is a lake after all. Above, we touched upon the subject of its unique transparency. This phenomenon has a logical explanation – the water in the lake is extremely poor in minerals and practically no organic impurities. In addition, the liquid has a quite low salt content – they're not more than 100 milligrams per liter. But the Baikal water is very rich in oxygen, resulting in every summer and autumn is here for real life.

1. In Baikal is concentrated 10% of all fresh water reserves on Earth

The volume of water in the lake is so large that meticulous Analytics are not lazy and made the following calculation. If conditionally divide all the water from the lake between the people of Russia, each had 150 000 tons of liquid (about 2 700 rail tank cars 60 tonnes). To say that a lot – not to say anything. The uniqueness of lake Baikal is that it is a lake full of fresh water. Therefore, each drop represents the world's supply of this precious liquid. According to official data in the lake is a tenth of the total freshwater resource on our planet.
