Deepest lakes in the world

The Caspian Sea is the largest enclosed inland body of water on Earth by area, variously classed as the world's largest lake or a full-fledged sea. The ancient inhabitants of its coast perceived the Caspian Sea as an ocean, probably because of its saltiness and large size. It has a salinity of approximately 1.2% (12 g/l), about a third of the salinity of most seawater

Lake Matano, also known as Matana, is a natural lake in South Sulawesi, Indonesia. With a depth of 590 m (1,940 ft), it is the deepest lake in Indonesia (ranked by maximum depth), and the 10th deepest lake in the world. The surface elevation from mean sea level is only 382 m (1,253 ft), which means that the deepest portion of the lake is below sea level (cryptohollow). It is one of the two major lakes (the other being Lake Towuti) in the Malili Lake system

Russian scientists discovered an underwater lake 1,200 meters under Arctic ice. Microorganisms that were found in thew water of the ice lake used to live on planet Earth millions of years ago.The lake was named Vostok, after Russia's Vostok Arctic scientific station

The Great Slave Lake is the second-largest lake in the Northwest Territories of Canada (after Great Bear Lake), the deepest lake in North America at 614 metres and the tenth-largest lake in the world. It is 469 km (291 mi) long and 20 to 203 km wide. It covers an area of 27,200 km2 (10,502 sq mi) in the southern part of the territory. Its given volume ranges from 1,070 km3 to 1,580 km3 and up to 2,088 km3making it the 10th or 12th largest.

Crater Lake is a caldera lake in the western United States, located in south-central Oregon. It is the main feature of Crater Lake National Park and is famous for its deep blue color and water clarity. The lake partly fills a nearly 2,148-foot (655 m)-deep calderathat was formed around 7,700 (± 150) years ago by the collapse of the volcano Mount Mazama. There are no rivers flowing into or out of the lake; the evaporation is compensated for by rain and snowfall at a rate such that the total amount of water is replaced every 250 years. With a depth of 1,943 feet (592 m), the lake is the deepest in the United States, and the seventh or ninth deepest in the world, depending on whether average or maximum depth is measured

Lake Tanganyika is an African Great Lake. It is estimated to be the second largest freshwater lake in the world by volume, and the second deepest, in both cases, after only Lake Baikal in Siberia; it is also the world's longest freshwater lake. The lake is divided among four countries - Tanzania, Democratic Republic of the Congo, Burundi, and Zambia, with Tanzania (46%) and DRC (40%) possessing the majority of the lake. The water flows into the Congo River system and ultimately into the Atlantic Ocean.

Issyk-Kul is an endorheic lake in the northern Tian Shan mountains in eastern Kyrgyzstan. It is the tenth largest lake in the world by volume (though not in surface area), and the second largest saline lake after the Caspian Sea. Although it is surrounded by snow-capped peaks, it never freezes;hence its name, which means "hot lake" in the Kyrgyz language

Lake Malawi, also known as Lake Nyasa in Tanzania and Lago Niassa in Mozambique, is an African Great Lake and the southernmost lake in the East African Rift system, located between Malawi, Mozambique and Tanzania. It is the ninth largest lake in the world and the third largest and second deepest lake in Africa. It is home to more species of fish than any other lake including about 1000 species of cichlids

Lake Baikal is a rift lake in Russia, located in southern Siberia, between Irkutsk Oblast to the northwest and the Buryat Republic to the southeast. Lake Baikal is the largest (by volume) freshwater lake in the world, containing roughly 20% of the world's unfrozen surface fresh water.With a maximum depth of 1,642 m (5,387 ft), Baikal is the world's deepest lake.  It is considered among the world's clearest lakes and is considered the world's oldest lake - at 25 million years. It is the seventh-largest lake in the world by surface area. With 23,615.39 km3 (5,700 cu mi) of fresh water, it contains more water than all the North American Great Lakes combined
