1. Lake Baikal, Russia
File:Lake Baikal-Listwjanka.jpg
Lake Baikal (Russian: о́зеро Байка́л, tr. Ozero Baykal, IPA: [ˈozʲɪrə bɐjˈkal]; Buryat: Байгал нуур, Mongolian: Байгал нуур, Baygal nuur, meaning "nature lake";) is a rift lake in the south of the Russian region of Siberia, between the Irkutsk Oblast to the northwest and the Buryat Republic to the southeast.
Lake Baikal is the most voluminous freshwater lake in the world, containing roughly 20% of the world's unfrozen surface fresh water, and at 1,642 m (5,387 ft), the deepest. It is also among the clearest of all lakes, and thought to be the world's oldest lake at 25 million years. It is the 7th largest lake in the world by surface area.

2. Lake Tanganyika, Tanzania, Congo, Burundi, Zambia

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, the Democratic Republic of the Congo, Burundi, and Zambia, with Tanzania (46%) and the DRC (40%) possessing the majority of the lake. The water flows into the Congo River system and ultimately into the Atlantic Ocean.
It extends for 676 km (420 mi) in a general north-south direction and averages 50 km (31 mi) in width. The lake covers 32,900 km2 (12,700 sq mi), with a shoreline of 1,828 km (1,136 mi), a mean depth of 570 m (1,870 ft) and a maximum depth of 1,470 m (4,820 ft) (in the northern basin). It holds an estimated 18,900 cubic kilometres (4,500 cu mi).[4] It has an average surface temperature of 25°C and a pH averaging 8.4.

3. Caspian, Iran, Russia, Turkmenistan, Kazakhstan, Azerbaijan Sea

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 sea has a surface area of 371,000 km2 (143,200 sq mi) (not including Garabogazköl Aylagy) and a volume of 78,200 km3 (18,800 cu mi). It is in an endorheic basin (it has no outflows) and is bounded to the northwest by Russia, to the west by Azerbaijan, to the south by Iran, to the southeast by Turkmenistan, and to the northeast by Kazakhstan.
The ancient inhabitants of its coast perceived the Caspian Sea as an ocean, probably because of its saltiness and seeming boundlessness. It has a salinity of approximately 1.2%, about a third the salinity of most seawater.
The Southern Caspian is the deepest, with oceanic depths of over 1,000 metres (3,300 ft), and maximum depth of 1,025 m (3,360 ft).

4. Lake Vostok, Antarctica

Lake Vostok (Russian: озеро Восток, Ozero Vostok, lit. "Lake East") is the largest of Antarctica's almost 400 known subglacial lakes. Lake Vostok is located at the southern Pole of Cold, beneath Russia's Vostok Station under the surface of the central East Antarctic Ice Sheet, which is at 3,488 m (11,444 ft) above mean sea level. The surface of this fresh water lake is approximately 4,000 m (13,100 ft) under the surface of the ice, which places it at approximately 500 m (1,600 ft) below sea level. Measuring 250 km (160 mi) long by 50 km (30 mi) wide at its widest point, and covering an area of 12,500 km2 (4,830 sq mi) and an average depth of 432 m (1,417 ft), it has an estimated volume of 5,400 km3 (1,300 cu mi). The lake is divided into two deep basins by a ridge. The liquid water over the ridge is about 200 m (700 ft), compared to roughly 400 m (1,300 ft) deep in the northern basin and 800 m (2,600 ft) deep in the southern. 
Max. depth 900 m (3,000 ft).

5. Lago O'Higgins / San Martin, Chile and Argentina

It has a surface area of 1,013 km², an elevation of 250 metres above mean sea level, and a shoreline length of 525 km. Viewed from above, the lake consists of a series of finger-shaped flooded valleys, of which 554 km² are in Chile and 459 km² in Argentina, although sources differ on the precise split, presumably reflecting water level variability. The lake is the deepest in the Americas with a maximum depth of 836 metres near O'Higgins Glacier, and its characteristic milky light-blue color comes from rock flour suspended in its waters. It is mainly fed by the Mayer River and other streams, and its outlet, the Pascua River, discharges water from the lake towards the Pacific Ocean at a rate of 510 m³/s. The O'Higgins Glacier flows eastwards towards the lake, as does the Chico Glacier. Both of these glaciers are part of the Southern Patagonian Ice Field which extends for approximately 350 kilometres in a north-south direction to the west of Lake O'Higgins.
Immigrants did not settle in the arid windy area around the lake until the 1910s, when British, Scandinavians and Swiss started raising sheep for wool.
The most common tourist route for visiting the lake is that between El Chaltén in Argentina and Villa O'Higgins in Chile, including a ferry through the lake on the Chilean side.
Water from lake O'Higgins flows into Pacific Ocean through the Pascua River.

6. Lake Malawi, Malawi, Mozambique, Tanzania

Lake Malawi (Lake Nyasa, or 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. The third largest and second deepest lake in Africa, it is also the ninth largest in the world. It is reportedly the habitat of more species of fish than any other body of freshwater, including more than 1000 species of cichlids, and was officially declared a reserve by the Government of Mozambique on June 10, 2011. Lake Malawi is a Meromictic lake; permanent stratification and the oxic-anoxic boundary are maintained by moderately small chemical and thermal gradients.
Max. depth 706 m.

7. Issyk-Kul, Kyrgyzstan
File:Issyk-Kul Monument Aug 2006.JPG
Issyk Kul (also Ysyk Köl, Issyk-Kol: Kyrgyz: Ысык-Көл [ɯsɯqkœl]; Russian: Иссык-Куль) is an endorheic lake in the northern Tian Shan mountains in eastern Kyrgyzstan. It is the tenth largest lake in the world by volume 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 (Chinese: 熱海; literally "Hot Sea" in Chinese texts).
Lake Issyk Kul has a length of 182 kilometres (113 mi), a width of up to 60 kilometres (37 mi), and covers an area of 6,236 square kilometres (2,408 sq mi). This makes it the second largest mountain lake in the world behind Lake Titicaca in South America. Located at an altitude of 1,607 metres (5,272 ft), it reaches 668 metres (2,192 ft) in depth.

8. Great Slave Lake, Canada

Great Slave Lake (French: Grand lac des Esclaves) is the second-largest lake in the Northwest Territories of Canada (after Great Bear Lake), the deepest lake in North America at 614 metres (336 fathoms; 2,014 ft), and the tenth-largest lake in the world. It is 480 km (300 mi) long and 19 to 109 km (12 to 68 mi) 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 (260 cu mi) to 1,580 km3 (380 cu mi) and up to 2,088 km3 (501 cu mi) making it the 10th or 12th largest.

9. Crater Lake, United States

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 caldera that was formed around 7,700 (± 150) years ago by the collapse of the volcano Mount Mazama. Human interaction is traceable back to the indigenous Native Americans witnessing the eruption of 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. At 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.

10. Lake Matano, Indonesia

Lake Matano (Indonesian: Danau 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 (cryptodepression). It is located at 2°29′7″S 121°20′0″E. It is one of the two major lakes (the other being Lake Towuti) in the Malili Lake system.
