Lake Baikal is the world’s deepest lake. It has a maximum 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 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 freshwater with 23,615.39 cubic kilometers (5,700 cubic miles). It contains more water than that of all the North American Great Lakes combined.
For comparison, the deepest lake in the United States is Crater Lake, a volcanic crater in southern Oregon. Its deepest measured depth is 594 meters (1,949 feet). Crater Lake is the ninth deepest lake in the world.
Lake Baikal facts
Here are 10 amazing facts about Lake Baikal:
- 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. During the winter, the water transparency in open sections can be as much as 30-40 meters (100-130 feet), but during the summer it is typically 5-8 meters (15-25 ft), which is still very impressive!
- As mentioned above, Lake Baikal contains roughly 20% of the world’s unfrozen surface freshwater 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 rich and unusual water wildlife . That’s why the lake is so important for 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.
- There are more than 30 rocky islands in Lake Baikal. One of them, the Olkhon island is the world’s third-largest island in a lake. Its surface area is 730 km2 (280 sq mi). The lake-islands larger than Olkhon are:
- Manitoulin Island in Lake Huron, Canada – 2,766 km2 (1,068 sq mi)
- René-Levasseur Island in the Manicouagan Reservoir, Quebec, Canada – 2,000 km2 (770 sq mi)
- Lake Baikal’s average surface temperature has risen by almost 1.5 °C (2.7 °F) in the last 50 years. As a result, the period when the lake is covered by ice is shorter now.
