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.

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.

The total surface is 94,250 square miles (244,106 km 2), and the total volume (measured at the low water datum) is 5,439 cubic miles (22,671 km 3), slightly less than the volume of Lake Baikal (5,666 cu mi or 23,615 km 3, 22–23% of the world's surface fresh water).
A reliable volume figure requires a bathymetric survey. [9] Therefore, mean depth figures are not available for many deep lakes in remote locations. [9] The average lake on Earth has the mean depth 41.8 meters (137.14 feet) [9]
Below are the reservoirs (artificial lakes) in the world with a surface area exceeding 500 km 2 (190 sq mi). Reservoirs can be formed conventionally, by damming the outlet of a canyon or valley to form a lake; the largest of this type is Ghana's Lake Volta, with a water surface of 8,500 km 2 (3,300 sq mi).
Historically it was an ancient lake. Now, it is a large tidal bay/inlet rather than a lake in the traditional sense. It is saline and directly connected to the Caribbean Sea, leading many to consider it a large lagoon or bay.

The volume of water inflow into Lake Baikal during the 1897 flood is estimated to have been approximately 22.2 cubic kilometres (5.3 cu mi). [10] Based on the observations of increased water level during floods, it has been deduced that flooding from the Selenge River can affect the environment of Lake Baikal.
