In the world today, there are four known lakes in the world that go beyond 1 km of depth.
Lake Baikal. With a maximum depth of 1,637m, Lake Baikal is the deepest lake in the world and largest freshwater lake by volume in the world. Located in Siberia, it is also considered the world's oldest lake, dating to some 25-30 million years back, and contains more water than the North American Great Lakes combined.

Lake Tanganyika. At second place with a maximum depth of 1,470m, Lake Tanganyika is also the world's second oldest freshwater lake. It is an African Great Lake and outflows into the Congo River system and ultimately into the Atlantic Ocean. Lake Tanganyika is shared by four countries - largely by Tanzania (46%) and the DRC or Democratic Republic of Congo (40%), with Burundi and Zambia covering less than 15% of the lake.
