Situated in south-east Siberia, the 3.15-million-ha Lake Baikal is the oldest (25 million years) and deepest (1,700 m) lake in the world. It contains 20% of the world's total unfrozen freshwater reserve. Known as the 'Galapagos of Russia', its age and isolation have produced one of the world's richest and most unusual freshwater faunas, which is of exceptional value to evolutionary science. |

Deepest Lake
The world's deepest lake is Lake Baikal, in Siberia, Russia. The deepest point of the lake, the Olkhon Crevice, has a depth of 1,637 m (5,371 ft), of which 1,181 m (3,875 ft) are below sea level. It is also the oldest freshwater lake on Earth, having formed between 20 and 25 million years ago. Baikal also contains one-fifth of all the world’s fresh surface water! The lake is roughly crescent-shaped, 636 km (395 miles) long, with a surface area of 31,500 km² (12,200 miles²). |
