Collectively, Earth's lakes hold 199,000 km 3 of water. [7] Most lakes are in the high northern latitudes, far from human population centers. [8] [9] The North American Great Lakes, which contain 21% of the world's fresh water by volume, [10] [11] [12] are an exception. The Great Lakes Basin is home to more than 35 million people. [13]
Pangong Tso; Lake Baikal – Lake Baikal is located in Siberia in southeastern Russia, just north of Mongolia. Considered the oldest surviving freshwater lake on the planet, it is also the deepest body of water in Asia at 5,315 feet (1,620 m), and the largest freshwater lake by volume, containing 20% of the planet's fresh water.
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.
Other lakes are found in depressed landforms or along the courses of mature rivers, where a river channel has widened over a basin formed by eroded floodplains and wetlands. Some lakes are found in caverns underground. Some parts of the world have many lakes formed by the chaotic drainage patterns left over from the last ice age.
Fresh water can easily become polluted by human activities or due to naturally occurring processes, such as erosion. Fresh water makes up less than 3% of the world's water resources, and just 1% of that is readily available. About 70% of the world's freshwater reserves are frozen in Antarctica. Just 3% of it is extracted for human consumption.
The deepest area is oceanic rather than continental crust. However, it is generally regarded by geographers as a large endorheic salt lake. Of these registered lakes; 10 have a deepest point above the sea level. These are: Issyk-Kul, Crater Lake, Quesnel, Sarez, Toba, Tahoe, Kivu, Nahuel Huapi, Van and Poso.
Lake Tegano, previously known as Lake Te Nggano, is the largest lake in the Solomon Islands and the Pacific region. It is located on Rennell Island and is the largest raised coral atoll in the world. The lake has been recognized as a World Heritage Site by UNESCO since 1998 due to its biodiversity and geological values. [3]
