⭐ Core Definition: Endorheic lake

An endorheic lake (also called a sink lake or terminal lake) is a collection of water within an endorheic basin, or sink, with no evident outlet. Endorheic lakes are generally saline as a result of being unable to get rid of solutes left in the lake by evaporation. These lakes can be used as indicators of anthropogenic change, such as irrigation or climate change, in the areas surrounding them. Lakes with subsurface drainage are called cryptorheic.

Endorheic lake in the context of Lake Van

Lake Van (Turkish: Van Gölü; Armenian: Վանա լիճ, romanizedVana lič̣; Kurdish: Gola Wanê) is the largest lake in Turkey. It lies in the Eastern Anatolia region of Turkey in the provinces of Van and Bitlis, in the Armenian highlands. It is a saline soda lake, receiving water from many small streams that descend from the surrounding mountains. It is one of the world's few endorheic lakes (a lake having no outlet) of size greater than 3,000 square kilometres (1,200 sq mi) and has 38% of the country's surface water (including rivers). A volcanic eruption blocked its original outlet in prehistoric times. It is situated at 1,640 m (5,380 ft) above sea level. Despite the high altitude and winter averages below 0 °C (32 °F), high salinity usually prevents it from freezing; the shallow northern section can freeze, but rarely.

Endorheic lake in the context of Lake Urmia

Lake Urmia is an endorheic salt lake in Iran. The lake is located in the Armenian Highlands, between the provinces of Azerbaijan in Iran, and west of the southern portion of the Caspian Sea. At its greatest extent, it was the largest lake in the Middle East. It is the sixth-largest saltwater lake on Earth, with a surface area of approximately 6,000 km (2,300 sq mi), a length of 140 km (87 mi), a width of 70 km (43 mi), and a maximum depth of 20 m (66 ft).

By late 2017, the lake had shrunk to 10% of its former size (and 1/60 of water volume in 1998) due to persistent general drought in Iran, but also the damming of the local rivers that flow into it, and the pumping of groundwater from the surrounding area. This dry spell was broken in 2019 and the lake began filling up once again, due to both increased rain and water diversion from the Zab River under the Urmia Lake Research Programme. The trend reversed again in early 2020s, and a combination of drought and administrative mismanagement caused a renewed acute drop in water levels. Based on NASA's satellite imagery, the lake has almost entirely dried up by September 2025.

Endorheic lake in the context of Aral Sea

The Aral Sea was an endorheic salt lake lying between Kazakhstan to its north and Uzbekistan to its south, which began shrinking in the 1960s and had largely dried up into desert by the 2010s. It was in the Aktobe and Kyzylorda regions of Kazakhstan and the Karakalpakstan autonomous region of Uzbekistan. The name roughly translates from Mongolic and Turkic languages to "Sea of Islands", a reference to the large number of islands (over 1,100) that once dotted its waters. The Aral Sea drainage basin encompasses Uzbekistan and parts of Afghanistan, Iran, Kazakhstan, Kyrgyzstan, Tajikistan, and Turkmenistan.

Formerly the third-largest lake in the world with an area of 68,000 km (26,300 sq mi), the Aral Sea began shrinking in the 1960s after the rivers that fed it were diverted by Soviet irrigation projects. By 2007, it had declined to 10% of its original size, splitting into four lakes: the North Aral Sea, the eastern and western basins of the once far larger South Aral Sea, and the smaller intermediate Barsakelmes Lake. By 2009, the southeastern lake had disappeared and the southwestern lake had retreated to a thin strip at the western edge of the former southern sea. In subsequent years occasional water flows have led to the southeastern lake sometimes being replenished to a small degree. Satellite images by NASA in August 2014 revealed that for the first time in modern history the eastern basin of the Aral Sea had completely dried up. The eastern basin is now called the Aralkum Desert.

Endorheic lake in the context of Lake Eyre

Lake Eyre (/ɛər/ AIR), officially known as Kati Thanda–Lake Eyre, is an endorheic lake in the east-central part of the Far North region of South Australia, some 700 km (435 mi) north of Adelaide. It is the largest ephemeral endorheic lake on the Australian continent, covering over 9,000 km (3,500 sq mi). The shallow lake is the depocentre of the vast endorheic Lake Eyre basin, and contains the lowest natural point in Australia, at approximately 15 m (49 ft) below sea level. The lake is most often empty, filling mostly when flooding occurs upstream in Channel Country, but almost always partially. On the rare occasions that it fills completely (only three times between 1860 and 2025), it is the largest lake in Australia, covering an area of up to 9,500 km (3,668 sq mi). When the lake is full, it has the same salinity as seawater, but becomes hypersaline as the lake dries up and the water evaporates. To the north of the lake is the Simpson Desert.

The lake was named in honour of Edward John Eyre, the first European to see it in 1840. It was officially renamed in December 2012 to include its Aboriginal Arabana name, Kati Thanda, in accordance with a policy of dual naming. The native title over most of the lake and surrounding region is held by the Arabana people, with the eastern portion allocated to the Dieri people.

Endorheic lake in the context of Great Salt Lake

The Great Salt Lake is the largest saltwater lake in the Western Hemisphere and the eighth-largest terminal lake in the world. It lies in the northern part of the U.S. state of Utah and has a substantial impact upon the local climate, particularly through lake-effect snow. It is a remnant of Lake Bonneville, a prehistoric body of water that covered much of western Utah.

The area of the lake can fluctuate substantially due to its low average depth of 16 feet (4.9 m). In the 1980s, it reached a historic high of 3,300 square miles (8,500 km), and the West Desert Pumping Project was established to mitigate flooding by pumping water from the lake into the nearby desert. In 2021, after years of sustained drought and increased water diversion upstream of the lake, it fell to its lowest recorded area at 950 square miles (2,500 km), falling below the previous low set in 1963.

Endorheic lake in the context of Lake Xochimilco

Lake Xochimilco (Spanish pronunciation: [sotʃiˈmilko]; Nahuatl languages: Xōchimīlco, pronounced [ʃoːtʃiˈmiːlko] listen) is an ancient endorheic lake, located in the present-day Borough of Xochimilco in southern Mexico City. It is the last remaining habitat of the axolotl.

The lake is within the Valley of Mexico hydrological basin, in central Mexico.

Endorheic lake in the context of Salton Sea

The Salton Sea is a shallow, landlocked, highly saline endorheic lake in Riverside and Imperial counties in Southern California. It lies on the San Andreas Fault within the Salton Trough, which stretches to the Gulf of California in Mexico. The lake is about 15 by 35 miles (24 by 56 km) at its widest and longest. A 2023 report put the surface area at 318 square miles (823.6 km). The Salton Sea became a resort destination in the 20th century, but saw die-offs of fish and birds in the 1980s due to contamination from farm runoff, and clouds of toxic dust in the current century as evaporation exposed parts of the lake bed.

Over millions of years, the Colorado River had flowed into the Imperial Valley and deposited alluvium (soil), creating fertile farmland, building up the terrain, and constantly moving its main course and river delta. For thousands of years, the river alternately flowed into the valley or diverted around it, creating either a salt lake called Lake Cahuilla or a dry desert basin, respectively. When the river diverted around the valley, the lake dried completely, as it did around 1580. Hundreds of archaeological sites have been found in this region, indicating possibly long-term Native American villages and temporary camps.

Endorheic lake in the context of Karatal River

The Karatal (Russian: Каратал) or Qaratal (Kazakh: Қаратал, lit.'Black Steppe') is a river of the Balkhash-Alakol Basin, Kazakhstan. It originates in the Dzungarian Alatau Mountains near the border with China and flows into the endorheic Lake Balkhash. It is the easternmost of two large rivers that flow into the lake; the other is the Ili. The Karatal is one of the main rivers of the historic region of Zhetysu. The river is 390 kilometres (240 mi) long and has a basin area of 19,100 square kilometres (7,400 sq mi).

The river flows west-southwest from the border with China before turning northwestward south of Taldykorgan and then northward when it reaches the Saryesik-Atyrau Desert, a large sand desert south of Lake Balkhash. The river empties into Lake Balkhash near the centerpoint of its southern side. Karatal freezes up in December and stays icebound until March. Because of diversions for irrigation, the river's flow into Lake Balkash is limited.

Endorheic lake in the context of Turkana Basin

The greater Turkana Basin in East Africa (mainly northwestern Kenya and southern Ethiopia, smaller parts of eastern Uganda and southeastern South Sudan) determines a large endorheic basin, a drainage basin with no outflow centered around the north-southwards directed Gregory Rift system in Kenya and southern Ethiopia. The deepest point of the basin is the endorheic Lake Turkana, a brackish soda lake with a very high ecological productivity in the Gregory Rift.

A narrower definition for the term Turkana Basin is also in widespread use and means Lake Turkana and its environment within the confines of the Gregory Rift in Kenya and Ethiopia. This includes the lower Omo River valley in Ethiopia. The Basin in the narrower definition is a site of geological subsidence containing one of the most continuous and temporally well controlled fossil records of the Plio-Pleistocene with some fossils as old as the Cretaceous. Among the Basin's critical fossiliferous sites are Lothagam, Allia Bay, and Koobi Fora.
