The origin of the lakes can be divided into waste (the deepest – type Topozero, Pyaozero), glacial, depression which wapahani the glacier and subglacial streams (lakes of medium and shallow depths), and Zapadno river, resulting from block of river valleys by glacial sediments (Ondozero, Gimolskoye).
Like rivers, all the lakes of Karelia belong to the basins of White and Baltic seas.

The cleanest and deepest lake — Baikal. Its length is 620 km, the width ranges from 32 to 74 kilometers. The depth of the lake in the deepest part of the crack length is equal to 1940 meters. The volume of fresh water in the lake is 2,300 cubic kilometers.
African sister of lake Baikal geographers call lake Tanganyika. It originated in Eastern Africa many millions of years ago. Under the influence of tectonic forces in the earth’s surface there were two giant cracks. And in the place where now splashing water of lake Tanganyika, formed two large abysses – trenches. Gradually they filled with water, and there were two closed lakes.
It took many millennia, and these reservoirs are connected, forming lake Tanganyika. In local dialect the name of the lake means “sail”. The similarities of lake Baikal and Tanganyika is that they are similar in size and shape, as well as the origin of their basins. In addition, these are two of the most ancient and deepest freshwater lake in the world, Tanganyika equal Depth of 1470 metres, almost 700 metres below sea level. The lake water remarkably clear and pure, and its surface is so smooth that reminds a mirror.
