lake tanganyika location

[19] Tanganyika cichlids are generally benthic (found at or near the bottom) and/or coastal. According to a legend of the indigenous people from some parts of the Fiji islands in the South Pacific Ocean, the Fijians originated from Tanganyika. [9] The Malagarasi River, which is Tanzania's second largest river, enters the east side of Lake Tanganyika. Comparatively narrow, varying in width from 10 to 45 miles (16 to 72 km), it covers about 12,700 square miles (32,900 square km) and forms the boundary between Tanzania and the Democratic … [21] Storm's water cobra, a threatened subspecies of banded water cobra that feeds mainly on fish, is only found in Lake Tanganyika, where it prefers rocky shores. The central began to form 9–12 million years ago (Mya), the northern 7–8 Mya and the southern 2–4 Mya.[11]. It drains into the Congo River system and ultimately into the Atlantic Ocean. This outflow is apparently not more than 12,000 years old, and resulted from lava flows blocking and diverting the Kivu basin's previous outflow into Lake Edward and then the Nile system, and diverting it to Lake Tanganyika. Tanganyika, historical eastern African state that in 1964 merged with Zanzibar to form the United Republic of Tanganyika and Zanzibar, later renamed the United Republic of Tanzania. The lake may also have at times had different inflows and outflows; inward flows from a higher Lake Rukwa, access to Lake Malawi and an exit route to the Nile have all been proposed to have existed at some point in the lake's history. [12][20], Lake Tanganyika and associated wetlands are home to Nile crocodiles (including famous giant Gustave), Zambian hinged terrapins, serrated hinged terrapins, and pan hinged terrapins (last species not in the lake itself, but in adjacent lagoons). It has been described as "practically endorheic" for this reason. Ring in the new year with a Britannica Membership, This article was most recently revised and updated by, https://www.britannica.com/place/Lake-Tanganyika, Official Site of the Conservation Lake Tanganyika, Africa, Tanganyika, Lake - Children's Encyclopedia (Ages 8-11), Lake Tanganyika - Student Encyclopedia (Ages 11 and up). It is the deepest lake in Africa. Historically, Lake Tanganyika levels have oscillated between 773 and 776 m, and there is no evidence of long-term decreasing trends. Lindqvist, O.V. Lake Tanganyika’s location is also notable for lying in the floral regions between Western and Eastern Africa. [19] A unique evolutionary radiation in the lake is the 15 species of Mastacembelus spiny eels, all but one endemic to its basin. Its waters tend to be brackish. The lake stretches from the north to the south and has the total area close to 89 thousand square miles. [7], The catchment area of the lake is 231,000 km2 (89,000 sq mi). Be on the lookout for your Britannica newsletter to get trusted stories delivered right to your inbox. The vessel was later raised in 1924 and renamed MV Liemba (see transport). [citation needed]. It holds an estimated 18,900 km3 (4,500 cu mi). On Dec. 12, 2014, the ferry MV Mutambala capsized on Lake Tanganyika, and more than 120 lives were lost. Lake Tanganyika is a famous lake situated in the eastern part of African continent, between the countries of Tanzania, Zambia, the Democratic Republic of Congo, and Burundi. The one major outflow is the Lukuga River, which empties into the Congo River drainage. [15], The lake is stratified and seasonal mixing generally does not extend beyond depths of 150 m (490 ft). Lake Tanganyika - Burundi, Democratic Republic of the Congo, Tanzania, Zambia. Its three basins, which in periods with much lower water levels were separate lakes, are of different ages. At least 90% of the water influx is from rain falling on the lake's surface and at least 90% of the water loss is from direct evaporation. Elevation. Tetra Press, Germany. [28][29] Some of the endemics do occur slightly into the upper Lukuga River, Lake Tanganyika's outflow, but further spread into the Congo River basin is prevented by physics (Lukuga has fast-flowing sections with many rapids and waterfalls) and chemistry (Tanganyika's water is alkaline, while the Congo's generally is acidic). Hutter; Yongqi; and Chubarenko (2011). [71], Crustaceans are also highly diverse in Tanganyika with more than 200 species, of which more than half are endemic. Two ferries carry passengers and cargo along the eastern shore of the lake: MV Liemba between Kigoma and Mpulungu and MV Mwongozo between Kigoma and Bujumbura. [18][38] Six catfish genera are entirely restricted to the lake basin: Bathybagrus, Dinotopterus, Lophiobagrus, Phyllonemus, Pseudotanganikallabes and Tanganikallabes. It was from there, in June 1916, that they launched a bombing raid on German positions in and around Kigoma. The BBC documentarian Michael Palin stayed on board the MV Liemba and travelled across the lake. Lake Tanganyika, second largest of the lakes of eastern Africa. Salonen; Högmander; Langenberg; Mölsä; Sarvala; Tarvainen; and Tiirola (2012). (1992). The southerly winds are slowing down which limits the ability for the mixing of nutrients. They are referred to as thalassoids, which can be translated to "marine-like". [14] Southern winds create upwells of deep nutrient-rich water on the southern end of the lake. Thus, it depends on a high inflow through the Ruzizi out of Lake Kivu to keep the lake high enough to overflow. It extends for 676 km (420 mi) in a general north-south direction and averages 50 km (31 mi) in width. multipunctatus. Congo, Tanzania, and Zambia. [34] Others have proposed splitting the Tanganyika cichlids into as many as 12–16 tribes (in addition to previous mentioned, Bathybatini, Benthochromini, Boulengerochromini, Cyphotilapiini, Eretmodini, Greenwoodochromini, Perissodini and Trematocarini). Longitude of center. Omissions? Though fed by a number of rivers, the lake is not the centre of an extensive drainage area. 3:25-8:45S, 29:10-31:10E; 773 m above sea level. Lake Tanganyikan Cichlids, pp. Please refer to the appropriate style manual or other sources if you have any questions. [30][32] This is linked to the high age of Tanganyika, as it is far older than the other lakes. P. 11. Encyclopaedia Britannica's editors oversee subject areas in which they have extensive knowledge, whether from years of experience gained by working on that content or via study for an advanced degree.... Where would you travel to reach the world’s second deepest lake? Similar Images . The project is scheduled to take five years at a total cost of US$27 million. [13] At depths greater than 400 m (1,300 ft), the temperature is very stable at 23.1–23.4 °C (73.6–74.1 °F). [8], The lake has a complex history of changing flow patterns, due to its high altitude, great depth, slow rate of refill, and mountainous location in a turbulently volcanic area that has undergone climate changes. It occupies the southern end of the Western Rift Valley, and for most of its length the land rises steeply from its shores. [38] Among the endemic species are two of the world's smallest cichlids, Neolamprologus multifasciatus and N. similis (both shell dwellers) at up to 4–5 cm (1.6–2.0 in),[39][40] and one of the largest, the giant cichlid (Boulengerochromis microlepis) at up to 90 cm (3.0 ft). The lake's connection to the sea is dependent on a high water level allowing water to overflow out of the lake through the Lukuga River into the Congo. The lake covers 32,900 km (12,700 sq mi), with a … The pH value varies between 7.5 and 9.2, the total hardness between 10 and 12, and the water temperature between 24.5 and 25.5 degrees. These nutrients that are in deep water are vital in maintaining the aquatic food web. Precipation and evaporation play a greater role than the rivers. The cichlid pick up the eggs in their mouth as if they were their own. ", "Evolution of a unique predatory feeding apparatus: functional anatomy, development and a genetic locus for jaw laterality in Lake Tanganyika scale-eating cichlids", "Colour-assortative mating among populations of Tropheus moorii, a cichlid fish from Lake Tanganyika, East Africa", "Systematic revision of the formerly monotypic genus Tanganikallabes (Siluriformes: Clariidae)", "Mastacembelid eels support Lake Tanganyika as an evolutionary hotspot of diversification", "Reticulate phylogeny of gastropod-shell-breeding cichlids from Lake Tanganyika — the result of repeated introgressive hybridization", "Sub-Decadal Resolution in Sediments of Late Miocene Lake Pannon Reveals Speciation of Cyprideis (Crustacea, Ostracoda)", "Composition and seasonal variations in abundance of Copepod (Crustacea) populations from the northern part of Lake Tanganyika". [9] When not overflowing, the lake's exit into the Lukuga River typically is blocked by sand bars and masses of weed, and instead this river depends on its own tributaries, especially the Niemba River, to maintain a flow.[8]. Among the chain of lakes on the bottom of the Western Great Rift Valley, Lake Tanganyika is outstanding for its extraordinary north-south extension (670 km) and depth (1,470 m). Lake Tanganyika is an African Great Lake. EAST AFRICA SAFARI BOOKING TRIP IDEA FOR LAKE TANGANYIKA IN WESTERN TANZANIA When visiting Lake Tanganyika, we recommend combining it with offbeat parks in Southern and Western Tanzania such as Selous, Ruaha or Katavi ending with a … [37] Two additional lates are found in the lake, the Tanganyika lates (L. angustifrons) and bigeye lates (L. mariae), but both these are primarily benthic hunters, although they also may move into open waters. You would be hard pressed to find a more exclusive and secluded location on the shores of Lake Tanganyika. Lake Tanganyika, also known by the name of Tanganyika, is a body of water found on the African continent, specifically in the central area. [33] Tanganyika has the largest number of endemic cichlid genera of all African lakes. He noted the name "Liemba" for its southern part, a word probably from the Fipa language, and in 1927 this was chosen as the new name for the conquered German First World War ship Graf von Götzen which is still serving the lake up to the present time.[92]. Lake Tanganyika is the second largest fresh water lake in the world by volume and the second deepest lake after Lake Baikal in Siberia. One canoe was stationary with a lantern while another canoe holds one end of the net and the other circles the stationary one to meet up with the net. Aquarium Fish. [18][19] The oxygen-devoid deepest sections contain high levels of toxic hydrogen sulphide and are essentially lifeless,[4] except for bacteria. [12], Surface temperatures generally range from about 24 °C (75 °F) in the southern part of the lake in early August to 28–29 °C (82–84 °F) in the late rainy season in March—April. Under the command of Lieutenant Commander Geoffrey Spicer-Simson the British Royal Navy achieved the monumental task of bringing two armed motor boats HMS Mimi and HMS Toutou from England to the lake by rail, road and river to Albertville (since renamed Kalemie in 1971) on the western shore of Lake Tanganyika. [93], The war on the lake had reached a stalemate by this stage, with both sides refusing to mount attacks. Cumberlidge, N.; and Meyer, K. S. (2011). [12] Below this, it is around 8.7, gradually decreasing to 8.3–8.5 in the deepest parts of Tanganyika. [69] The latter is the largest Tanganyika snail and its shell is often used by small shell-dwelling cichlids. Articles from Britannica Encyclopedias for elementary and high school students. [78] Among these, Limnocaridina iridinae lives inside the mantle cavity of the unionid mussel Pleiodon spekei, making it one of only two known commensal species of freshwater shrimp (the other is the sponge-living Caridina spongicola from Lake Towuti, Indonesia). Lake Tanganyika is an African Great Lake. [93], As a result of their strengthened position on the lake, the Allies started advancing towards Kigoma by land, and the Belgians established an airbase on the western shore at Albertville. Even its current outlet is intermittent, thus may not have been operating when first visited by Western explorers in 1858. The Ruzizi (also sometimes spelled Rusizi) is a river, 117 kilometres (73 mi) long, that flows from Lake Kivu to Lake Tanganyika in Central Africa, descending from about 1,500 metres (4,900 ft) to about 770 metres (2,530 ft) above sea level over its length. A TIMELESS SANCTUARY ON THE SHORES OF LAKE TANGANYIKA. In order to avoid his prize ship falling into Allied hands, Zimmer scuttled the vessel on July 26, 1916. The location. In 1992 Lake Tanganyika featured in the British TV documentary series Pole to Pole. It is the longest freshwater lake in the world (410 miles [660 km]) and the second deepest (4,710 feet [1,436 metres]) after Lake Baikal in Russia. It is the largest rift lakein Africa and the second-largest lake by volume in the world. The lake reaches a maximum depth of 4,820 feet, while its average depth is about 1,870 feet. Burundi Bujumbura lake Tanganyika, windy cloudy sky and sand beach at sea lake in East Africa, Burundi sunset with boat. Nevertheless, others of these features are not consistent within the lakes and have not been adequately explained.…. This is correlating with less productivity in the lake. 767 metres (2516 feet) Geo­Names ID. Froese, Rainer and Pauly, Daniel, eds. [93], In 1965 Argentinian revolutionary Che Guevara used the western shores of Lake Tanganyika as a training camp for guerrilla forces in the Congo. Because of increasing global temperature there is a direct correlation to lower productivity in Lake Tanganyika. The steepest gradients occur over the first 40 kilometres (25 mi), where hydroelectric dams have been built. Lake Tanganyika is also a well-renowned venue for fresh water angling with the sheer number of fish in the lake rivalling the variety of species. CS1 maint: multiple names: authors list (. Tanganyika means "a great lake spreading out like a plain." Hippopotamuses and crocodiles abound, and the bird life is varied. [15][87] Currently, there are around 100,000 people directly involved in the fisheries operating from almost 800 sites. Lowe-McConnell, R.H. (1987). By the start of the war, the Germans had two warships on Lake Tanganyika: the 60 t (59 long tons; 66 short tons) Hedwig von Wissmann, and the 45 t (44 long tons; 50 short tons) Kingani. [91], The first known Westerners to find the lake were the British explorers Richard Burton and John Speke, in 1858. They located it while searching for the source of the Nile River. The lake of Usukuma would be called Tanganika, but the little lakes in Uhha (Musunya) would be called Kitanga. Lake Tanganyika and its Diverse Cichlids. Page (2006). Amongst the favourites are the nkupi, the goliath tigerfish and, perhaps above all, the Nile perch, which can reach up to 80kg in weight. Lake Tanganyika is situated within the Albertine Rift, the western branch of the East African Rift, and is confined by the mountainous walls of the valley. By signing up for this email, you are agreeing to news, offers, and information from Encyclopaedia Britannica. Later David Livingstone passed by the lake. 26, p. 203. How … [15] Former industrial fisheries, which boomed in the 1980s, have subsequently collapsed. [81] For example, the only other Rift Valley lake with endemic freshwater crabs are Lake Kivu and Lake Victoria with two species each. What is the lowest body of water on Earth? Our editors will review what you’ve submitted and determine whether to revise the article. stappersii). pp. With intriguing decor combining African artefacts and European antiques, Kalambo Falls Lodge is a celebration of diversity, capturing the wealth of Zambia's history. Loiselle, Paul (1994). 213–214. [51][66] Although not endemic on a genus level, six species of Chrysichthys catfish are only found in the Tanganyika basin where they live both in shallow and relatively deep waters;[51] in the latter habitat they are the primary predators and scavengers. [69] There are about 30 species of non-thalassoid snails in the lake, but only five of these are endemic, including Ferrissia tanganyicensis and Neothauma tanganyicense. The Lake Tanganyika Development Project (LTDP) is formulated within the framework of the Zambian Long Term Vision (known as Vision 2030) with which the country aims at becoming “A Prosperous Middle Income Nation by 2030”. Springer. [36] Some of the deep-water cichlids (e.g., Bathybates, Gnathochromis, Hemibates and Xenochromis) have been caught in places virtually devoid of oxygen, but how they are able to survive there is unclear. The lake is shaped in a rift, so it is long and somewhat narrow, lying in a valley about 2,000 feet below the tops of the surrounding mountains. [38][42], Bathybatini (E): Bathybates ferox is benthic and piscivorous, but the genus also includes pelagic species. [68] Many of the snails are unusual for species living in freshwater in having noticeably thickened shells and/or distinct sculpture, features more commonly seen in marine snails. Another German vessel, the Hedwig, was sunk in February 1916, leaving the Götzen as the only German vessel remaining to control the lake. The majority of the lake is located in the DRC and Tanzania. It extends for 676 km (420 mi) in a general north-south direction and averages 50 km (31 mi) in width. [13] The mixing mainly occurs as upwellings in the south and is wind-driven, but to a lesser extent, up- and downwellings also occur elsewhere in the lake. Lake Tanganyika is situated within the Albertine Rift, the western branch of the East African Rift, and is confined by the mountainous walls of the valley. DESCRIPTION. 9-10. Lake Tanganyika is another great filming location in DR Congo it is the second-largest freshwater lake in the world by volume and the second deepest lake after Lake Baikal in Siberia. [90], There are many methods in which the native people of the area were fishing. Many of the numerous peoples (predominantly Bantu-speaking) living on the lake’s eastern shores trace their origins to areas in the Congo River basin. [82][83], The diversity of other invertebrate groups in Lake Tanganyika is often not well-known, but there are at least 20 described species of leeches (12 endemics),[84] 9 sponges (7 endemic), 6 bryozoa (2 endemic), 11 flatworms (7 endemic), 20 nematodes (7 endemic), 28 annelids (17 endemic)[26] and the small hydrozoan jellyfish Limnocnida tanganyicae. Archaeological evidence attests to a long history of settlement in the area; by the 10th century ce, Most of them included using a lantern as a lure for fish that are attracted to light. [citation needed], Lake Tanganyika fish can be found exported throughout East Africa. [27] Almost all (98%) of the Tanganyika cichlids are endemic to the lake and it is thus an important biological resource for the study of speciation in evolution. [16] As a consequence of the stratification, the deep sections contain "fossil water". [67], Among the non-endemic fish, some are widespread African species but several are only shared with the Malagarasi and Congo River basins, such as the Congo bichir (Polypterus congicus), goliath tigerfish (Hydrocynus goliath), Citharinus citharus, six-banded distichodus (Distichodus sexfasciatus) and mbu puffer (Tetraodon mbu). However, the war on land was progressing, largely to the advantage of the Allies, who cut off the railway link in July 1916 and threatened to isolate Kigoma completely. [26][69][70] A total of 17 freshwater snail genera are endemic to the lake, such as Hirthia, Lavigeria, Paramelania, Reymondia, Spekia, Stanleya, Tanganyicia and Tiphobia. Barron's Educational Series. Stanley found also other names for the lake among different ethnic groups, like Kimana, Iemba and Msaga. Ecological Studies in Tropical Fish Communities. Of the 10 tribes in this subfamily, half are largely or entirely restricted to the lake (Cyprichromini, Ectodini, Lamprologini, Limnochromini and Tropheini) and another three have species in the lake (Haplochromini, Tilapiini and Tylochromini). From Limnology to Fisheries: Lake Tanganyika and Other Large Lakes. The largest rivers discharging into the lake are the Malagarasi, the Ruzizi, and the Kalambo, which has one of the highest waterfalls in the world (704 feet [215 metres]; see Kalambo Falls). Latitude and longitude coordinates are: -6.500000, 29.833332. Kigoma and Rukwa, Tanzania; Shaba and Kivu, Zaire; Northern, Zambia; and Burundi. Wright, J.J.; and L.M. [35][19] Tanganyika cichlids differ extensively in ecology and include species that are herbivores, detritivores, planktivores, insectivores, molluscivores, scavengers, scale-eaters and piscivores. While every effort has been made to follow citation style rules, there may be some discrepancies. This accounts for the many Bantu speaking natives living in the lake’s eastern region whose origins can be traced to the Congo River basin region. [10], Lake Tanganyika is an ancient lake. Apparently, it has rarely in the past had an outflow to the sea. Speke continued and found the actual source, Lake Victoria. It is the longest freshwater lake in the world (410 miles [660 km]) and the second deepest (4,710 feet [1,436 metres]) after Lake Baikal in Russia. [37], Among the more unusual fish in the lake are the endemic, facultatively brood parasitic "cuckoo catfish", including at least Synodontis grandiops[63] and S. LAKE TANGANYIKA This vast inland sea was first made known to the European world in the mid 1880’s by the English explorers Richard Burton and John Speke in their pursuit of the source of the Nile. Yucca Beach Restaurant and bar, with its array of imported, as well as locally-crafted beers, is the most popular spot among tourists. Due to the lake's tropical location, it has a high rate of evaporation. Lake Tanganyika is shared among four countries namely Burundi, Democratic Republic of Congo, Tanzania, and Zambia. Major commercial fishing began in the mid-1950s and has, together with global warming (limiting the habitat of temperature sensitive species), had a heavy impact on the fish populations, causing significant declines. This led the German commander, Gustav Zimmer, to abandon the town and head south. Physics of Lakes, volume 1: Foundation of the Mathematical and Physical Background. The 660-kilometer-long and 4,710-foot-deep Lake Tanganyika is the longest freshwater lake in the world, and the second deepest one after only Lake Baikal in Russia. [27][41], Many cichlids from Lake Tanganyika, such as species from the genera Altolamprologus, Cyprichromis, Eretmodus, Julidochromis, Lamprologus, Neolamprologus, Tropheus and Xenotilapia, are popular aquarium fish due to their bright colors and patterns, and interesting behaviors. [citation needed]. According to experts, lake level variations are both seasonal and interannual. There were three basic forms. [69] All the Tanganyika thalassoids, which are part of Prosobranchia, are endemic to the lake. The lake was the scene of two celebrated battles during World War I. Their appearance is now believed to be the result of the highly diverse habitats in Lake Tanganyika and evolutionary pressure from snail-eating fish and, in particular, Platythelphusa crabs. [30] All Tanganyika cichlids are in the subfamily Pseudocrenilabrinae. At somewhere between nine and 13 million years old, it’s also one of the oldest.
