Among the splendor of Russian nature, it is impossible not to pay attention to the vast freshwater lakes.
We present to your attention 7 the cleanest lakes of the country.
Location: the South of Eastern Siberia, Irkutsk region.
The first in this list simply can not be called, this unique reservoir. Apart from the fact that it is the deepest (1700 m.), largest (more than 30 thousand sq. m.) the lake, it is also filled with very clean water.
To see the bottom at 20 meters depth do nothing! Its water has an unusual blue color, and even the ice when the lake freezes over, almost completely transparent! The purity of the water remains a mystery to modern scientists, the lake gradually gets covered with sludge, but not Baikal!
Some researchers suggest that the reason lies in the location of the reservoir — at the junction of tectonic plates — it is constantly updated with fresh groundwater, due to the movement of these plates.
The exact answer about the age of the lake, nor the purity of its water is not able to give one today, however, thanks to these inexplicable factors in the lake inhabited by such animals, which are not found in any other corner of our great planet.
Location: southern Urals, Chelyabinsk region.

WISCONSIN, on November 16. In canadian-American shore of lake superior, the largest area of freshwater lake in the world, over the last 20 years have seen major changes. Professor of Ankur Desai from the University of Wisconsin and his colleagues came to an unexpected conclusion: the increase in the temperature of atmospheric air in the summer has led to the fact that the speed of the winds blowing over the lake, has increased, reports Infox .
According to scientists, for the same reason, the increased speed and currents. Naturally, such changes could not but affect the inhabitants of the water.
While in sight of limnologen (Ostrovidov) managed to get only the phytoplankton. The scientists conducted their research since 1985. Based on data collected using three hydrological buoys and satellite imagery, Professor Desai and his colleagues have figured out what is going on with the Top.
According to scientists, the temperature in the surface layers of the lake during the summer period increased at a rate of 1.2°C in one decade. And the water heats up 15% faster than the air over the lake. “The fact that the temperature regime of a lake depends largely on the amount Continue reading
All the continents of our Earth can be found lakes, both large and small, both artificial and natural. According to preliminary calculations, their number is about 5 thousand pieces. And now we will talk about the largest lake in the world and its features.
The largest lake in the world and its paradox
No matter how surprising and ironic as it may sound, but the largest lake in the world is the sea. Indeed, the Caspian sea, which is so named because of its enormous size (its area is over 370 thousand square kilometers), has no outlet to the ocean and not freshwater, and therefore are actually recognized by the lake.
By the way, the biggest lake boasts big depth: the maximum level reaches 1025 meters. Thus, it is smaller than lake Baikal is more than 600 meters. It is conditionally possible to say that this sea found 2 parts of the world: Asia and Europe . Its shores are washed by 5 countries.
The largest freshwater lakes in the world
If we consider the rating of: “The largest freshwater lake in the world “, is the leader lake superior. It is located on the border of Canada and the United States. It belongs to the Great lakes system. Continue reading
