The world’s deepest lake is the Lake Baikal, which has a depth of 1,642 meters (5,387 feet). It is a rift lake in the south of the Russian region of Siberia. Its bottom is at 4,215 feet (1,285 meters) below the sea level. In terms of volume, Lake Baikal is also the world’s largest freshwater lake; it contains roughly 20% of the world’s unfrozen surface fresh water with 23,615.39 cubic kilometers (5,700 cubic miles). It contains more water than that of all the North American Great Lakes combined.

Lake Baikal facts

• Lake Baikal is home to more than 1,700 species of plants and animals, two-thirds of which can be found nowhere else in the world and was declared a UNESCO World Heritage Site in 1996.
• A rift lake is a lake formed as a result of subsidence related to movement on faults within a rift zone, an area of extensional tectonics in the continental crust. They are often found within rift valleys and may be very deep. Rift lakes may be bounded by large steep cliffs along the fault margins.
• Lake Baikal is covered with ice every winter, typically between January and May. In some places, the ice can be more than 2 meters (6.56 feet) thick.
• The water of Lake Baikal is extraordinarily clean, transparent and saturated with oxygen. The high transparency is thanks to numerous aquatic organisms purifying the water and making it similar to distilled water.
• As mentioned above, Lake Baikal contains roughly 20% of the world’s unfrozen surface fresh water with 23,615.39 cubic kilometers (5,700 cubic miles). It contains more water than that of all the North American Great Lakes combined.
• At 25 million years old, this remarkable lake is also the oldest lake in the world.
• Lake Baikal is also known as the Galapagos of Russia because its age and isolation produced a rich and unusual water wildlife That’s why the lake is so important for the evolutionary science. Occasionally, new species are discovered and it has been estimated that we know of only 70-80% of all the species inhabiting the lake.
• It is surrounded by mountain-taiga landscapes, which are also protected to preserve their natural state.

For a comparison, the deepest lake in the United States is Crater Lake, a volcanic crater in southern Oregon. It’s deepest measured depth is 594 meters (1,949 feet). It is the ninth deepest lake in the world.
