About Baikal Lake Lake Baikal is the world's oldest and deepest lake. The amazing purity of its waters, huge territory and deep make it the most famous and exiting lake in the world. It lies in southern Siberia, almost in the center of Asia. Its watershed extends over the Mongolian border for 636 km. Its area is about 31,500 square kilometers and equal to the area of such countries as Belgium, Switzerland, Netherlands or Denmark. The coastline of Baikal is almost 2000 km long, which is equal to the distance from Arkhangelsk to Rostov. Lake Baikal contains one-fifth of the world's surface water resources, and four-fifth of fresh waters of Russia. Its basin could hold waters of all five American Great Lakes, which are 8 times bigger.

The Baikal is surrounded by mountain chains which are covered with taiga lifting turned to bushes and mountain tundra. The southern hills are generally unforested.

More than 300 Siberian rivers fall into Lake Baikal and only one flows out – the powerful and quick Angara carrying its waters to the Yenisei. There are 22 islands in the Lake. The biggest one Olhon is 729 square km.

Flora and Fauna The Baikal is also one of the most interesting biotopes in the world. As it is quite an isolated lake, the nature there could develop balanced and varied. The animal world of the lake forms a remarkably complementary and harmonies system. The flora and fauna of the lake are mostly endemic. It is inhabited by over 58 fish species. The most well-known species are: the omul, Siberian whitefish, the grayling, the taimen, the sturgeon, the Baikal oil fish, and goldilocks. More than 2000 plants grow on the lake coasts. Lake Baikal forms an ideal habitat for typical sea mammal –the nerpa (the Baikal seal). Still not all organisms inhabited Baikal are explored. Scientists continue to discover more and more unknown species.
