However, because it is also the deepest lake, [6] with a maximum depth of 1,642 metres (5,387 feet; 898 fathoms), [1] Lake Baikal is the world's largest freshwater lake by volume, containing 23,615.39 km 3 (5,670 cu mi) of water [1] or 22–23% of the world's fresh surface water, [7] [8] more than all of the North American Great Lakes combined.

For aquatic habitat, the park is in the "Lake Baikal" freshwater ecoregion (WWF ID#601), a region that covers the immediate drainage basin of the lake. The water of the lake itself is characterized by oxygen saturation over 70% (even at maximum depths), high levels of clarity, and low calcium. Ice cover lasts from January–February to May each ...
Academician Ridge is an underwater, structural high separating two of Lake Baikal's three basins, the Central and North basins Situated in the central part of the Baikal Rift, it serves as an "accommodation zone", transferring "motion between faults of similar displacement but different orientation" (Hutchinson et al., 1992).
Lake Tanganyika (32,900 square kilometres (12,700 sq mi), elevation 773 metres (2,536 ft)) is the largest and deepest of the Rift Valley lakes (more than 1,400 metres (4,600 ft)), and is the second deepest fresh water lake on the planet (after Lake Baikal). [1]
A frozen Lake Baikal, near Olkhon Island. Russia, home to over 100,000 rivers, [1] is divided into twenty watershed districts. It has one of the world's largest surface water resources, with its lakes containing approximately one-quarter of the world's liquid fresh water. [21] Russia is second only to Brazil by total renewable water resources. [22]
The Baikal seal (Pusa sibirica), also known as Lake Baikal seal or Baikal nerpa, is a species of earless seal endemic to Lake Baikal in Siberia, Russia. Like the Caspian seal, it is related to the Arctic ringed seal. The Baikal seal is one of the smallest true seals and the only exclusively freshwater pinniped species. [2]
Freshwater lakes contain about 87% of this fresh surface water, including 29% in the African Great Lakes, 22% in Lake Baikal in Russia, 21% in the North American Great Lakes, and 14% in other lakes. Swamps have most of the balance with only a small amount in rivers, most notably the Amazon River .
This article lists lakes with a water volume of more than 100 km 3, ranked by volume. The volume of a lake is a difficult quantity to measure. [1] Generally, the volume must be inferred from bathymetric data by integration. Lake volumes can also change dramatically over time and during the year, especially for salt lakes in arid climates.
