A number of natural lakes throughout the world are drying or completely dry due to irrigation or urban use diverting inflow. [1] [2]
The Aral Sea was an endorheic lake lying between Kazakhstan in the north and Uzbekistan in the south which began shrinking in the 1960s and had largely dried up by the 2010s. The name roughly translates as "Sea of Islands", referring to over 1,100 islands that had dotted its waters. In the Mongolic and Turkic languages, aral means "island, archipelago". The Aral Sea drainage basin encompasses Uzbekistan and parts of Tajikistan, Turkmenistan, Kyrgyzstan, Kazakhstan, Afghanistan, and Iran.
The Karakum Desert, also spelled Kara-Kum and Gara-Gum, is a desert in Central Asia. Its name in Turkic languages means "black sand": "kum" means sand; "kara" is a contraction of garaňky: "dark" or may pre-date that in this language family. This refers to the shale-rich sand generally beneath the sand of much of the desert. It occupies about 70 percent, 350,000 km2 (140,000 sq mi), of Turkmenistan.
Lake Maracaibo is a lagoon in northwestern Venezuela, the largest lake in South America and one of the oldest on Earth, formed 36 million years ago in the Andes Mountains. The fault in the northern section has collapsed and is rich in oil and gas resources. It is Venezuela's main oil producing area and an important fishing and agricultural producing area. It is inhabited by a quarter of the country's population and is also the place with the most frequent lightning on earth. The famous Catatumbo lightning can illuminate nighttime navigation, and eutrophication caused by oil pollution is a major environmental problem facing the lake.
An endorheic basin is a drainage basin that normally retains water and allows no outflow to other external bodies of water, such as rivers or oceans, where drainage converges instead into lakes or swamps, permanent or seasonal, that equilibrate through evaporation. They are also called closed or terminal basins, internal drainage systems, or simply basins. Endorheic regions contrast with exorheic regions, where surface waters eventually drain into the ocean. Endorheic water bodies include some of the largest lakes in the world, such as the Caspian Sea, the world's largest inland body of water.
Artemia is a genus of aquatic crustaceans also known as brine shrimp. It is the only genus in the family Artemiidae. The first historical record of the existence of Artemia dates back to the first half of the 10th century AD from Lake Urmia, Iran, with an example called by an Iranian geographer an "aquatic dog," although the first unambiguous record is the report and drawings made by Schlösser in 1757 of animals from Lymington, England. Artemia populations are found worldwide in inland saltwater lakes, but not in oceans. Artemia are able to avoid cohabiting with most types of predators, such as fish, by their ability to live in waters of very high salinity.
The Salton Sea is a shallow, landlocked, highly saline body of water in Riverside and Imperial counties at the southern end of the U.S. state of California. It lies on the San Andreas Fault within the Salton Trough, which stretches to the Gulf of California in Mexico.
Lake Balkhash is a lake in southeastern Kazakhstan, one of the largest lakes in Asia and the 15th largest in the world. It is located in the eastern part of Central Asia and sits in the Balkhash-Alakol Basin, an endorheic (closed) basin. The basin drains seven rivers, the primary of which is the Ili, bringing most of the riparian inflow; others, such as the Karatal, bring surface and subsurface flow. The Ili is fed by precipitation, largely vernal snowmelt, from the mountains of China's Xinjiang region.
The McMurdo Dry Valleys are a row of largely snow-free valleys in Antarctica, located within Victoria Land west of McMurdo Sound. The Dry Valleys experience extremely low humidity and surrounding mountains prevent the flow of ice from nearby glaciers. The rocks here are granites and gneisses, and glacial tills dot this bedrock landscape, with loose gravel covering the ground. It is one of the driest places on Earth and has not seen rain for nearly two million years.
A salt lake or saline lake is a landlocked body of water that has a concentration of salts and other dissolved minerals significantly higher than most lakes. In some cases, salt lakes have a higher concentration of salt than sea water; such lakes can also be termed hypersaline lakes, and may also be pink lakes on account of their colour. An alkalic salt lake that has a high content of carbonate is sometimes termed a soda lake.
Lake Urmia is an endorheic salt lake in Iran. The lake is located between the provinces of East Azerbaijan and West 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 and the sixth-largest saltwater lake on Earth, with a surface area of approximately 5,200 km2 (2,000 sq mi), a length of 140 km (87 mi), a width of 55 km (34 mi), and a maximum depth of 16 m (52 ft).
The Etosha Pan is a large endorheic salt pan, forming part of the Cuvelai-Etosha Basin in the north of Namibia. It is a hollow in the ground in which water may collect or in which a deposit of salt remains after water has evaporated. The 120-kilometre-long (75-mile-long) dry lakebed and its surroundings are protected as Etosha National Park, Namibia's second-largest wildlife park, covering 22,270 square kilometres (8,600 sq mi). The pan is mostly dry but after a heavy rain it will acquire a thin layer of water, which is heavily salted by the mineral deposits on the surface.
Mar Chiquita or Mar de Ansenuza is an endorheic salt lake located in the northeast of the province of Córdoba, in central Argentina. The northeast corner of the lake also extends into southeastern Santiago del Estero Province. It is the largest of the naturally occurring saline lakes in Argentina. The lake is located in parts of five departments in the two provinces.
Environmental issues in Turkmenistan are most visible in three significant areas: desertification, the drying of the Aral Sea, and chemical pollution. All three of these areas are directly linked to agricultural practices in the country.
The Sonny Bono Salton Sea National Wildlife Refuge is located in the Imperial Valley of California, 40 miles (64 km) north of the Mexican border. Situated at the southern end of the Salton Sea, the refuge protects one of the most important nesting sites and stopovers along the Pacific Flyway. Despite its location in the Colorado Desert, a subdivision of the larger Sonoran Desert, the refuge contains marine, freshwater, wetland, and agricultural habitats which provide sanctuary for hundreds of birds and wetland species, including several that have been listed as endangered or sensitive by the U.S. Fish and Wildlife Service.
The Murray Darling Depression , also known as the Murray-Darling woodlands and mallee, is a 19,717,651 HA biogeographic region and an ecoregion in southeastern Australia consisting of a wooded plain through which flow two of Australia's biggest rivers, the Murray and the Darling. There are several modern human settlements in the bioregion including Ivanhoe and Manilla, but the region also contains some of the oldest known human occupation sites in Australia.
The Salton Trough is an active tectonic pull-apart basin, or graben. It lies within the Imperial, Riverside, and San Diego counties of southeastern California, United States and extends south of the Mexico–United States border into the state of Baja California, Mexico. The northwestern end of the trough starts at the San Gorgonio Pass in Riverside County, and extends 115 miles (185 km) southeast to the Gulf of California. Major geographical features located in the trough include the Coachella Valley, the Salton Sea, and the Imperial Valley, in the United States, and the western side of the Mexicali Valley, and the Colorado River Delta in Mexico.
Imperial Valley Geothermal Project is a complex of eleven geothermal power stations located in the Salton Sea Geothermal Field, along the southeastern shore of the Salton Sea in the Imperial Valley of California. It is the second largest geothermal field in the United States after The Geysers in Northern California.
Miqan Wetland is a wetland located in Markazi province, Iran. In years with good rainfall, the wetland has significant water level and in the years with less rain, the surface of the wetland generally dries and becomes a desert. The height of the wetland is 1700 meters above sea level and the water inside of it varies in different seasons. Miqan is supplied from different water sources such as rainfall, water of three rivers known as Qarah Kahriz (Koohrood) River, Farahan River, Shahrab River, and Arak ‘s wastewater treatment sewage. The area of the wetland is about 25,000 hectares, which includes a lake with three islands in the middle and the surrounding plains. Archaeologically, the wetland's formation dates back to the Paleocene, which was due to the movement of the surrounding tectonic plates of the earth.
