Saline lake in the context of "Issyk Kul"

Issyk-Kul (Russian: Иссык-Куль) or Ysyk-Köl (Kyrgyz: Ысык-Көл [ɯ̀sɯχ cʰɵl]; lit. 'Hot Lake') is an endorheic saline lake in the western Tianshan Mountains in eastern Kyrgyzstan, just south of a dividing range separating Kyrgyzstan from Kazakhstan. It is the eighth-deepest lake in the world, the eleventh-largest lake in the world by volume (though not in surface area), the deepest lake whose deepest point is above sea level (939 meters or 3,080 feet), and the second-largest saline lake. Although it is located at a lofty elevation of 1,607 metres (5,272 ft) and subject to severe cold during winter, it rarely freezes over due to high salinity, hence its name, which in the Kyrgyz language means "warm lake".

The lake is a Ramsar site of globally significant biodiversity and forms part of the Issyk-Kul Biosphere Reserve.

Üüreg Lake (Mongolian: Үүрэг нуур, ᠡᠭᠦᠷᠭᠡ ᠨᠠᠭᠤᠷ, Üüreg nuur) is a saline lake in an endorheic basin in Sagil, Uvs Province, Mongolia, north-west of the Great Lakes Hollow, near the western edge of the Uvs Nuur basin. The Tsagaan river gorge (Tsagaan Shuvuut Uul) lies on the west side of the lake.

Nahcolite is a soft, colourless or white carbonate mineral with the composition of sodium bicarbonate (NaHCO₃) also called thermokalite. It crystallizes in the monoclinic system.

Nahcolite was first described in 1928 for an occurrence in a lava tunnel at Mount Vesuvius, Italy. Its name refers to the elements which compose it: Na, H, C, and O. It occurs as a hot spring and saline lake precipitate or efflorescence; in differentiated alkalic massifs; in fluid inclusions as a daughter mineral phase and in evaporite deposits.

Lake Poopó (Spanish: Lago Poopó Spanish: [ˈlaɣo po.oˈpo]) was a large saline lake in a shallow depression in the Altiplano in Oruro Department, Bolivia, at an altitude of approximately 3,700 m (12,100 ft). Due to the lake's length and width (90 by 32 km; 56 by 20 mi), it made up the eastern half of Oruro, known as a mining region in southwest Bolivia. The permanent part of the lake body covered approximately 1,000 square kilometres (390 sq mi) and it was the second-largest lake in the country. The lake received most of its water from the Desaguadero River, which flows from Lake Titicaca at the north end of the Altiplano. Since the lake lacked any major outlet and had a mean depth of less than 3 m (10 ft), the surface area differed greatly seasonally.

In 2002, the lake was designated as a site for conservation under the Ramsar Convention. By December 2015, the lake had completely dried up, leaving only a few marshy areas. Despite the lake rebounding from two previous recorded drying instances, as of 2016, the lake's recovery is considered unlikely. Suggested causes of the decline are the melting of the Andes glaciers and loss of their waters, because of a drought due to climate change, as well as continued diversion of water for mining and agriculture.

Qinghai Lake is the largest lake in China. Located in an endorheic basin in Qinghai Province, to which it gave its name, Qinghai Lake is classified as an alkaline salt lake. The lake has fluctuated in size, shrinking over much of the 20th century but increasing since 2004. It had a surface area of 4,317 km (1,667 sq mi), an average depth of 21 m (69 ft), and a maximum depth of 25.5 m (84 ft) in 2008.
