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. It is an endorheic basin (a basin without outflows) located between Europe and Asia. It is bounded by Kazakhstan to the northeast, Russia to the northwest, Azerbaijan to the west, Iran to the south, and Turkmenistan to the southeast.
Chott Melrhir also known as Chott Melghir or Chott Melhir is an endorheic salt lake in northeastern Algeria. It the westernmost part of a series of depressions, which extend from the Gulf of Gabès into the Sahara. They were created between Miocene and Early Pleistocene as a result of compression accompanying the formation of the Atlas Mountains. With the maximum area of about 6,700 km2 (2,600 sq mi), Chott Melrhir is the largest lake in Algeria. It lies almost entirely below the sea level and contains the lowest point in Algeria, −40 meters (−130 feet). Its size varies over the year and is usually larger than 130 km (81 mi) from east to west. The nearby cities are Biskra (60 km north-east), El Oued and Touggourt (85 km south).
Chott Ech Chergui is a large endorheic salt lake in Saïda Province, northwestern Algeria. It is located at 34.35°N 0.5°E in the level terrain of the Hautes Plaines region between the Tell Atlas and the Saharan Atlas and is one of the largest lakes in Algeria.
The Chott el Hodna is a very shallow saline lake in Algeria. It is located within an endorheic basin in the Hodna region, towards the eastern end of the Hautes Plaines. The Chott el Hodna includes seasonal brackish and saline pools and marshes, but the central zone of the lake is characterized by a complete absence of vegetation.
The Sebkha Azzel Matti is an endorheic basin in central Algeria, North Africa.
The Tunisian salt lakes are a series of lakes in central Tunisia, lying south of the Atlas Mountains at the northern edge of the Sahara. The lakes include, from east to west, the Chott el Fedjedj, Chott el Djerid, and Chott el Gharsa.
Chott el Djerid (Arabic: شط الجريد Šoṭṭ el-Jarīd) also spelled Sciott Gerid and Shott el Jerid, is a large endorheic salt lake in southern Tunisia. The name can be translated from the Arabic into English as "Lagoon of the Land of Palms".
The Qattara Depression (Arabic: منخفض القطارة Munḫafaḍ al-Qaṭṭārah) is a depression in northwestern Egypt, specifically in the Matruh Governorate. The depression is part of the Western Desert of Egypt. The Qattara Depression lies below sea level, and its bottom is covered with salt pans, sand dunes, and salt marshes. The depression extends between the latitudes of 28°35' and 30°25' north and the longitudes of 26°20' and 29°02' east.
The Siwa Oasis (Arabic: واحة سيوة, Wāḥat Sīwah, Berber languages: Isiwan, ⵉⵙⵉⵡⴰⵏ) is an urban oasis in Egypt between the Qattara Depression and the Great Sand Sea in the Western Desert, nearly 50 km (30 mi) east of the Libyan border, and 560 km (348 mi) from Cairo.
The Chad Basin is the largest endorheic basin in Africa, centered on Lake Chad. It has no outlet to the sea and contains large areas of desert or semi-arid savanna. The drainage basin is roughly coterminous with the sedimentary basin of the same name, but extends further to the northeast and east. The basin spans seven countries, including most of Chad and a large part of Niger. The region has an ethnically diverse population of about 30 million people as of 2011, growing rapidly.
Lake Barombi Koto, also known as Lake Barombi Kotto or Lake Barombi-ba-Kotto, is a small lake in the volcanic chain in the Southwest Region of Cameroon. It is a volcanic lake with a diameter of about 1.2 km (0.75 mi). There is a small island in the middle, which is densely inhabited by the Barombi, a tribe of fishers.
Lake Barombi Mbo or Barombi-ma-Mbu is a lake near Kumba in the Southwest Region of Cameroon. It is located in the Cameroon volcanic chain, and is the largest volcanic lake in this region. It is one of the oldest radiocarbon-dated lakes in Africa, with the youngest lava flow in it being about one million years old. On old colonial maps the area was known as Elefanten Sea (Elephant Lake), but the elephants living in the area were extirpated due to ivory trading.
Lake Bermin (sometimes spelled Bemin or Beme) is a small lake in the volcanic chain in the Southwest Region of Cameroon. It is a volcanic lake with a diameter of about 700 m (2,300 ft) and a crater rim that rises to a height of about 46 m (150 ft). This highly isolated lake is roughly circular in shape, lacks an inflow, but has an outflow into the Cross River system.
Lake Dissoni, also known as Lake Soden, is a small lake in the volcanic chain in the Southwest Region of Cameroon. This volcanic lake has diameter of about 1.25 km (0.78 mi) and is at the southeastern foot of the Rumpi Hills.
About 1 km (0.6 mi) south of Lake Barombi Koto is the even smaller Lake Mboandong, another shallow crater lake with a diameter of about 0.4 km (0.25 mi). There is no inflow and the only outflow is a small stream during the wet season.
The Makgadikgadi Pan (Botswana salt flats), a salt pan situated in the middle of the dry savanna of north-eastern Botswana, is one of the largest salt flats in the world. The pan is all that remains of the formerly enormous Lake Makgadikgadi, which once covered an area larger than Switzerland, but dried up several thousand years ago.
The Afar Triangle (also called the Afar Depression) is a geological depression caused by the Afar Triple Junction, which is part of the Great Rift Valley in East Africa. The region has disclosed fossil specimens of the very earliest hominins, that is, the earliest of the human clade; and it is thought by some paleontologists to be the cradle of the evolution of humans, see Middle Awash, Hadar.
Lake Abaya (Abaya Hayk in Amharic) is a lake in the Southern Nations, Nationalities, and Peoples' Region of Ethiopia. It is located in the Main Ethiopian Rift, east of the Guge Mountains.
Lake Turkana, formerly known as Lake Rudolf, is a lake in the Kenyan Rift Valley, in northern Kenya, with its far northern end crossing into Ethiopia. It is the world's largest permanent desert lake and the world's largest alkaline lake. By volume it is the world's fourth-largest salt lake after the Caspian Sea, Issyk-Kul, and Lake Van (passing the shrinking South Aral Sea), and among all lakes it ranks 24th.
Lake Logipi is a saline, alkaline lake that lies at the northern end of the arid Suguta Valley in the northern Kenya Rift. It is separated from Lake Turkana by the Barrier volcanic complex, a group of young volcanoes that last erupted during the late 19th Century or early 20th Century. Saline hot springs discharge on the northern shoreline of Lake Logipi and at Cathedral Rocks near its southern limit, and help to maintain water at times of extreme aridity.
Lake Baringo is, after Lake Turkana, the most northern of the Kenyan Rift Valley lakes, with a surface area of about 130 square kilometres (50 sq mi) and an elevation of about 970 metres (3,180 ft). The lake is fed by several rivers, Molo, Perkerra and Ol Arabel, and has no obvious outlet; the waters are assumed to seep through lake sediments into the faulted volcanic bedrock. It is one of the two freshwater lakes in the Rift Valley in Kenya, the other being Lake Naivasha.
Lake Bogoria is a saline, alkaline lake that lies in a volcanic region in a half-graben basin south of Lake Baringo, Kenya, a little south of the equator. Lake Bogoria, like Lake Nakuru, Lake Elmenteita, and Lake Magadi further south in the Rift Valley, and Lake Logipi to the north, is home at times to one of the world's largest populations of lesser flamingos. The lake is a Ramsar site and Lake Bogoria National Reserve has been a protected National Reserve since November 29, 1973. Lake Bogoria is shallow (about 10 m depth), and is about 34 km long by 3.5 km wide, with a drainage basin of 700 sq km.
Lake Nakuru is one of the Rift Valley soda lakes at an elevation of 1754 m above sea level. It lies to the south of Nakuru, in the rift valley of Kenya and is protected by Lake Nakuru National Park.
Lake Elmenteita, also spelled Elementaita, is a soda lake, in the Great Rift Valley, about 120 km northwest of Nairobi, Kenya.
