From high mountain basins to tectonic rifts, Asia’s lakes reflect a wide range of geology and climates. Many support unique ecosystems and have depths that tell stories about the landscape’s formation and history.
There are 28 Deepest Lakes in Asia, ranging from Baikal to Van; the list below shows the continent’s vertical variety. For each lake, entries are organized with Country,Max depth (m),Coordinates (lat, long), and you’ll find below.
Which lake is the deepest in Asia and how deep is it?
Lake Baikal is the deepest in Asia (and the world) with a commonly cited maximum depth around 1,642 m, though exact figures can vary slightly between surveys; its depth reflects its rift-basin origin and long geological history.
How reliable are the depth and coordinate figures in the list?
Depth and coordinate data come from hydrographic surveys, scientific papers, and official sources; while modern measurements are generally reliable, older or remote surveys can differ, so use the provided Country, Max depth (m), and Coordinates (lat, long) for cross-checking and further verification.

Baikal
The world’s deepest, oldest, and most voluminous freshwater lake, holding over 20% of the planet’s unfrozen surface fresh water. This Siberian rift lake is a UNESCO World Heritage site known for its unique biodiversity. (Source: ILEC, Russian Academy of Sciences).

Caspian Sea
The world’s largest lake by area, this endorheic saline basin is a remnant of the ancient Paratethys Sea. Its southern basin contains its deepest point, and it is a crucial feature of Eurasian geography. (Source: IHO, various national surveys).

Issyk-Kul
The world’s second-largest high-altitude lake and second-largest saline lake. Despite freezing winter temperatures in the Tian Shan mountains, its slight salinity prevents it from freezing over, earning it the name “Hot Lake”. (Source: Kyrgyz Academy of Sciences).

Matano
An ancient tectonic lake on Sulawesi island, this is Indonesia’s deepest lake. It is known for its exceptionally clear, ultra-oligotrophic waters and a large number of endemic fish species, making it a hotspot for biodiversity research. (Source: Indonesian Institute of Sciences).

Toba
The world’s largest volcanic lake, occupying the caldera of a supervolcano in Sumatra. A colossal eruption around 75,000 years ago formed the lake and is believed to have caused a decade-long global winter. (Source: Volcanological Survey of Indonesia).

Sarez
A geologically young lake formed in 1911 when a massive earthquake triggered a landslide, creating the 567-meter-high Usoi Dam—the tallest natural dam in the world. It is located high in the remote Pamir Mountains. (Source: Tajik Academy of Sciences).

Van
The largest lake in Turkey, Lake Van is a saline soda lake of tectonic origin with no outlet. It has a high pH, allowing only a few fish species to survive, and features underwater microbialites (stromatolites). (Source: Turkish State Hydraulic Works).

Poso
