Top 7 in Top 10 largest lakes on the planet you may not know.
Lake Baikal is located in the Northern hemisphere, Lake Baikal, also known as the Natural Lake, the Rift Lake (the lake formed due to the shift in the Ant Rift area). It is located north of the Mongolian border, in the southern Siberian region of Russia, between the States of the Buryat Republic and Irkutsk Oblast. Lake Baikal is the largest non-glacial freshwater lake in the world, and contains about 20% of the world's fresh water. It is also regarded as one of the world's most obvious lakes. Along with being the 7th largest lake in the world, with a total surface area of 31,500 km², it is also the world's largest lake and the deepest lake in the world. It may even be one of the oldest lakes on our planet, with an estimated age of not less than 25 million years. The average depth of the lake is 744.4 m, with the deepest point to 1642 metres (the Rift lake is usually deeper than the non-rift lake, due to the depth of the rift formed by the reactivity and water filling). Thanks to the isolation with people and long-standing, the world's most varied and unusual freshwater fauna has been created. The basin of the lake is located entirely in Russia and the main water supply is the Barguzin, Selenge and Upper Angara rivers. It was drained by the Angara River.
