Congo River

The great Congo River (Kongo: Nzâdi Kôngo; French: Fleuve Congo; Portuguese: rio Congo), formerly known as the Zaire River under the Mobutu regime, is the second longest river in Africa, shorter only than the Nile, as well as the second largest river in the world by discharge volume, following only the Amazon. It is also the world's deepest recorded river, with measured depths in excess of 220 m (720 ft).[2] The Congo-Lualaba-Chambeshi River system has an overall length of 4,700 km (2,920 mi), which makes it the world's ninth-longest river. The Chambeshi is a tributary of the Lualaba River, and Lualaba is the name of the Congo River upstream of Boyoma Falls, extending for 1,800 km (1,120 mi).

Measured along with the Lualaba, the main tributary, the Congo River has a total length of 4,370 km (2,715 mi). It is the only river to cross the equator twice.[3] The Congo Basin has a total area of about 4,000,000 km2 (1,500,000 sq mi), or 13% of the entire African landmass.

The name Congo/Kongo river originates from the Kingdom of Kongo once located on the southern bank of the river. The kingdom in turn was named for the indigenous Bantu Kongo people, known in the 17th century as "Esikongo".[4] South of the Kingdom of Kongo proper lay the similarly named Kakongo kingdom, mentioned in 1535. Abraham Ortelius in his world map of 1564 labeled as "Manicongo" the city at the mouth of the river.[5]

The tribal names in Kongo possibly derive from a word for a public gathering or tribal assembly. The modern name of the Kongo people or Bakongo was introduced in the early 20th century.

The name Zaire is from a Portuguese adaptation of a Kikongo word, nzere ("river"), a truncation of nzadi o nzere ("river swallowing rivers").[6] The river was known as Zaire during the 16th and 17th centuries; Congo seems to have replaced Zaire gradually in English usage during the 18th century, and Congo is the preferred English name in 19th-century literature, although references to Zahir or Zaire as the name used by the inhabitants remained common.[7]

The Democratic Republic of the Congo and the Republic of the Congo are named after it, as was the previous Republic of the Congo which had gained independence in 1960 from the Belgian Congo.

The Republic of Zaire during 1971–1997 was also named after the river, after its name in French and Portuguese.

Basin and course

The Congo's drainage basin covers 4,014,500 square kilometres (1,550,000 sq mi),[1] an area larger than India. The Congo's discharge at its mouth ranges from 23,000 to 75,000 cubic metres per second (810,000 to 2,650,000 cu ft/s), with an average of 41,000 cubic metres per second (1,400,000 cu ft/s).[1]

The river and its tributaries flow through the Congo Rainforest, the second largest rain forest area in the world, second only to the Amazon Rainforest in South America. The river also has the second-largest flow in the world, behind the Amazon; the third-largest drainage basin of any river, behind the Amazon and Plate rivers; and is one of the deepest rivers in the world, at depths greater than 220 m (720 ft).[2][8] Because its drainage basin includes areas both north and south of the equator, its flow is stable, as there is always at least one part of the river experiencing a rainy season.[9]

The sources of the Congo are in the highlands and mountains of the East African Rift, as well as Lake Tanganyika and Lake Mweru, which feed the Lualaba River, which then becomes the Congo below Boyoma Falls. The Chambeshi River in Zambia is generally taken as the source of the Congo in line with the accepted practice worldwide of using the longest tributary, as with the Nile River.

The Congo flows generally toward the northwest from Kisangani just below the Boyoma falls, then gradually bends southwestwards, passing by Mbandaka, joining with the Ubangi River, and running into the Pool Malebo (Stanley Pool). Kinshasa (formerly Léopoldville) and Brazzaville are on opposite sides of the river at the Pool, where the river narrows and falls through a number of cataracts in deep canyons (collectively known as the Livingstone Falls), running by Matadi and Boma, and into the sea at the small town of Muanda.

The Congo River Basin is one of the distinct physiographic sections of the larger Mid-African province, which in turn is part of the larger African massive physiographic division.

Although the Livingstone Falls prevent access from the sea, nearly the entire Congo above them is readily navigable in sections, especially between Kinshasa and Kisangani. Large river steamers worked the river until quite recently. The Congo River still is a lifeline in a land with few roads or railways.[10]

Railways now bypass the three major falls, and much of the trade of Central Africa passes along the river, including copper, palm oil (as kernels), sugar, coffee, and cotton. The river is also potentially valuable for hydroelectric power, and the Inga Dams below Pool Malebo are first to exploit the Congo river.

Hydro-electric power

The Congo River is the most powerful river in Africa. During the rainy season over 50,000 cubic metres (1,800,000 cu ft) of water per second flow into the Atlantic Ocean. Opportunities for the Congo River and its tributaries to generate hydropower are therefore enormous. Scientists have calculated that the entire Congo Basin accounts for 13 percent of global hydropower potential. This would provide sufficient power for all of sub-Saharan Africa's electricity needs.[11]

Currently there are about forty hydropower plants in the Congo Basin. The largest are the Inga dams, about 200 kilometres (120 mi) southwest of Kinshasa. The project was launched in the early 1970s, when the first dam was completed.[12] The plan as originally conceived called for the construction of five dams that would have had a total generating capacity of 34,500 megawatts. To date only the Inga I and Inga II dams have been built, generating 1,776 MW.[11]

In February 2005, South Africa's state-owned power company, Eskom, announced a proposal to expand generation through improvements and the construction of a new hydroelectric dam. The project would bring the maximum output of the facility to 40 gigawatts (54,000,000 hp), twice that of China's Three Gorges Dam.[13]

It is feared that these new hydroelectric dams could lead to the extinction of many of the fish species that are native to the river.[14]

Natural history

Chutes Livingstone
The beginning of the Livingstone Falls (Lower Congo Rapids) near Kinshasa

The current course of the Congo River formed 1.5–2 million years BP, during the Pleistocene.[15]

The Congo's formation may have led to the allopatric speciation of the bonobo and the common chimpanzee from their most recent common ancestor.[16] The bonobo is endemic to the humid forests in the region, as are other iconic species like the Allen's swamp monkey, dryas monkey, aquatic genet, okapi, and Congo peafowl.[17][18]

In terms of aquatic life, the Congo River Basin has a very high species richness, and among the highest known concentrations of endemics.[19] Until now, almost 700 fish species have been recorded from the Congo River Basin, and large sections remain virtually unstudied.[20] This is by far the highest diversity of any African river system (in comparison, the next richest are the Niger, Volta and Nile with about 210, 140 and 130 fish species, respectively).[21] Due to this and the great ecological differences between the regions in the Congo basin, it is often divided into multiple ecoregions (instead of treating it as a single ecoregion). Among these ecoregions, the Lower Congo Rapids alone has more than 300 fish species, including approximately 80 endemics[14] while the southwestern part (Kasai Basin) alone has more than 200 fish species, of which about a quarter are endemic.[22] The dominant fish families – at least in parts of the river – are Cyprinidae (carp/cyprinids, such as Labeo simpsoni), Mormyridae (elephantfishes), Alestidae (African tetras), Mochokidae (squeaker catfishes), and Cichlidae (cichlids).[23] Among the natives in the river is the huge, highly carnivorous giant tigerfish. Three of the more unusual endemics are the whitish (non-pigmented) and blind Lamprologus lethops, which is believed to live as deep as 160 metres (520 ft) below the surface,[14] Heterochromis multidens, which appears to be more closely related to cichlids of the Americas than other African cichlids,[24] and Caecobarbus geertsii, the only known cavefish in Central Africa.[25] There are also numerous endemic frogs and snails.[23][26] Several hydroelectric dams are planned on the river, and these may lead to the extinction of many of the endemics.[14]

Several species of turtles, and the slender-snouted, Nile and dwarf crocodile are native to the Congo River Basin. African manatees inhabit the lower parts of the river.[27]

In this 1853 map of Africa, the remaining Unexplored Region essentially corresponds to the Congo basin

The entire Congo basin is populated by Bantu peoples, divided into several hundred ethnic or tribal groups (see ethnic groups of the Democratic Republic of the Congo). Bantu expansion is estimated to have reached the Middle Congo by about 500 BC, and the Upper Congo by the first century AD. Remnants of the aboriginal population displaced by the Bantu migration, Pygmies/Abatwa of the Ubangian phylum, remain in the remote forest areas of the Congo basin.

The Kingdom of Kongo was formed around 1400 on the left banks of the lower Congo River. Its territorial control along the river remained limited to what corresponds to the modern Bas-Congo province. European exploration of the Congo begins in 1482, when Portuguese explorer Diogo Cão discovered the river estuary[28] (likely in August 1482), which he marked by a Padrão, or stone pillar (still existing, but only in fragments) erected on Shark Point. Cão also sailed up the river for a short distance, establishing contact with the Kingdom of Congo. The full course of the river remained unknown throughout the early modern period.[29]

The upper Congo basin runs west of the Albertine Rift.[28] Its connection to the Congo was unknown until 1877. The extreme northeast of the Congo basin was reached by the Nilotic expansion at some point between the 15th and 18th centuries, by the ancestors of the Southern Luo speaking Alur people. Francisco de Lacerda following the Zambezi reached the uppermost part of the Congo basin (the Kazembe in the upper Luapula basin) in 1796.

The upper Congo River, known as the Lualaba was first reached by the Arab slave trade by the 19th century. Nyangwe was founded as a slavers' outpost around 1860. David Livingstone was the first European to reach Nyangwe in March 1871.[28] Livingstone proposed to prove that the Lualaba connected to the Nile, but on 15 July, he witnessed a massacre of about 400 Africans by Arab slavers in Nyangwe, which experience left him too horrified and shattered to continue his mission to find the sources of the Nile, so he turned back to Lake Tanganyika.[30][31]

The middle reaches of the Congo remained unexplored from either the east or west, until Henry Morton Stanley's expedition of 1876–77. At the time one of the last open questions of the exploration of Africa (or indeed of the world) whether the Lualaba River fed the Nile (Livingstone's theory), the Congo[32] or even the Niger. Financed in 1874, Stanley's first trans-Africa exploration started in Zanzibar, and reached the Lualaba on October 17, 1876. Overland he reached Nyangwe, the centre of a lawless area containing cannibal tribes at which Tippu Tip based his trade in slaves. Stanley managed to hire a force from Tippu Tip, to guard him for the next 150 kilometres (90 mi) or so, for 90 days. The party left Nyangwe overland through the dense Matimba forest. On November 19 they reached the Lualaba again. Since the going through the forest was so heavy, Tippu Tip turned around with his party on December 28, leaving Stanley on his own, with 143 people, including 8 children and 16 women. They had 23 canoes. His first encounter with a local tribe was with the cannibal Wenya. In total Stanley would report 32 unfriendly meetings on the river, some violent, even though he attempted to negotiate a peaceful thoroughfare. But the tribes were wary as their only experience of outsiders was of slave traders.

On January 6, 1877, after 640 kilometres (400 mi), they reached Boyoma Falls (called Stanley Falls for some time after), consisting of seven cataracts spanning 100 kilometres (60 mi) which they had to bypass overland. It took them to February 7 to reach the end of the falls. Here Stanley learned that the river was called Ikuta Yacongo,[33] proving to him that he had reached the Congo, and that the Lualaba did not feed the Nile.

From this point, the tribes were no longer cannibals, but possessed firearms, apparently as a result of Portuguese influence. Some four weeks and 1,900 kilometres (1,200 mi) later he reached Stanley Pool (now Pool Malebo), the site of the present day cities Kinshasa and Brazzaville. Further downstream were the Livingstone Falls, misnamed as Livingstone had never been on the Congo: a series of 32 falls and rapids with a fall of 270 metres (900 ft) over 350 kilometres (220 mi). On 15 March they started the descent of the falls, which took five months and cost numerous lives. From the Isangile Falls, five falls from the foot, they beached the canoes and Lady Alice and left the river, aiming for the Portuguese outpost of Boma via land. On August 3 they reached the hamlet Nsada. From there Stanley sent four men with letters forward to Boma, asking for food for his starving people. On August 7 relief came, being sent by representatives from the Liverpool trading firm Hatton & Cookson. On August 9 they reached Boma, 1,001 days since leaving Zanzibar on November 12, 1874. The party then consisted of 108 people, including three children born during the trip. Most probably (Stanley's own publications give inconsistent figures), he lost 132 people through disease, hunger, drowning, killing and desertion.[34]

Kinshasa was founded as a trading post by Stanley in 1881 and named Léopoldville in honour of Leopold II of Belgium. The Congo basin was claimed by Leopold II as Congo Free State in 1885.

Bridges in the Congo Basin

The Congo river basin is notable for the lack of bridges crossing the main rivers, although there are a number of ferries available for crossing the great Congo river and the major tributaries. The main reasoning is the mere width of the Congo river and main rivers, and the second is the lack of funds to set up permanent river crossings, this is however slowly changing to the better.

Bridges on the Congo proper and Lualaba

There are only two bridges on the Congo river proper and main tributaries, which both are found in the DR Congo:

Bridges on the Uele and Kibali rivers

There is one bridge on the Uele River, and two on the Kibali River, which all lies in the northern province Haut-Uele of DR Congo:

  • The Niangara Bridge on the Uele, some 2,000 km along the tributary from the rivermouth, near the town Niangara.
  • The Dungu Bridge on the Kibali, some 2,050 km along the tributary from the rivermouth, near the town Dungu, at the confluence of Dungu and Kibali rivers, where the Uele river is formed.
  • The Kalimva Bridge on the Kibali, some 2,250 km along the tributary from the rivermouth, near the town Kalimva.

Bridges on the Lulua river

There are at least four bridges on the Lulua river in the province of Kasai of DR Congo:

  • Between the towns of Luebo and Tshimpumpu.
  • Near the town of Kananga.
  • At the town of Sanduwa.
  • West of the town of Diongo (also the location of a railway bridge on the Benguela Railway).

Aruwimi River

The Aruwimi River is a tributary of the Congo River, located to the north and east of the Congo.The Aruwimi begins as the Ituri River, which arises near Lake Albert, in the savannas north of the Kibale River watershed. It then runs generally south southwest until it is joined by the Shari River which flows by Bunia. The Ituri then turns west, through the Ituri Forest, becoming the Aruwimi where the Nepoko (or Nepoki) River joins it, at the town of Bomili. The river continues westward, joining the Congo at Basoko. The length of the Aruwimi–Ituri is about 1,030 kilometres (640 mi), with the Ituri being about 650 kilometres (400 mi) and the Aruwimi about 380 kilometres (240 mi). The Aruwimi is about 1.5 kilometres (0.93 mi) wide where it joins the Congo.

The watershed of the Ituri/Aruwimi is almost entirely dense forest, with just a handful of villages along its course, and crossed by roads in about four places. The Kango language (SIL code KZY) is spoken by several thousand villagers just south of Avakubi, and upper reaches of the Ituri are inhabited by the Mbuti (Pygmies).

The Aruwimi was explored by Henry Morton Stanley during his 1887 expedition to "rescue" Emin Pasha. The cataracts above Yambuya made it impossible to use the river for navigation, and the expedition had to go by land, with tremendous difficulty.














Baptist Community of the Congo River

The Baptist Community of the Congo River (French: Communauté Baptiste du Fleuve Congo) is a Baptist Christian denomination in Democratic Republic of the Congo. It is affiliated with the Church of Christ in the Congo and the Baptist World Alliance. The headquarters is in Kinshasa.

Boma, Democratic Republic of the Congo

Boma is a port town on the Congo River, some 100 km upstream from the Atlantic Ocean, in the Kongo Central province of the Democratic Republic of the Congo. It had an estimated population of 162,521 in 2012.Boma was the capital city of the Congo Free State and Belgian Congo (the modern Democratic Republic of the Congo) from 1 May 1886 to 1926, when the capital was moved to Léopoldville (since renamed Kinshasa). The port handles exports of tropical timber, bananas, cacao, and palm products.


Brazzaville (French pronunciation: ​[bʁazavil], Kongo: Balazavile) is the capital and largest city of the Republic of the Congo (Congo Republic). Constituting the financial and administrative centre of the country, it is located on the north side of the Congo River, opposite Kinshasa, Democratic Republic of the Congo (DR Congo). The population of the capital is estimated to exceed 1.8 million residents, comprising more than a third of the national populace, 40% of whom are employed in non-agricultural professions. During World War II, Brazzaville was also the capital of Free France between 1940 and 1942.

In 2013, Brazzaville was designated a City of Music by UNESCO, and has been a member of the Creative Cities Network since then.

Bushongo mythology

The Bushongo or Songora are an ethnic group from the Congo River and surrounding areas. The creation god(or chembe) in Bushongo mythology is called Bumba. He existed alone in darkness, the world consisting only of water. The god Bumba was said to appear like a gigantic man in form and white in color. The creation took place when he vomited forth the sun, moon, earth, plants and animals, and then humanity. Bomazi is the ancestor-god of the Bushongo.

Chambeshi River

The Chambeshi (or Chambezi) River of northeastern Zambia is the most remote headstream of the Congo River (in length) and therefore its source is in the Congo River. (However, by volume of water, the Lualaba River is the greater "source" of the Congo.)

The Chambeshi rises as a stream in the mountains of northeast Zambia near Lake Tanganyika at an elevation of 1,760 metres (5,770 ft) above sea level. It flows for 480 km into the Bangweulu Swamps, which are part of Lake Bangweulu, and by the end of the rainy season in May, it delivers a flood which recharges the swamps and inundates a vast floodplain to the southeast, supporting the Bangweulu Wetlands. The water then flows out of the swamps as the Luapula River.For more than 100 km of its length as it flows to the east of Kasama the river consists of a maze of channels in swamps about 2 km wide, in a floodplain up to 25 km wide. Further downstream, where it is bridged by the Kasama–Mpika road and the Tazara Railway, the permanent main channel is about 100 m wide, and up to 400 m wide in flood.

Congo Basin

The Congo Basin is the sedimentary basin of the Congo River. The Congo Basin is located in Central Africa, in a region known as west equatorial Africa. The Congo Basin region is sometimes known simply as the Congo.

The basin begins in the highlands of the East African Rift system with input from the Chambeshi River, the Uele and Ubangi Rivers in the upper reaches and the Lualaba River draining wetlands in the middle reaches. Due to the young age and active uplift of the East African Rift at the headlands, the river's yearly sediment load is very large but the drainage basin occupies large areas of low relief throughout much of its area. The basin is a total of 3.7 million square kilometers and is home to some of the largest undisturbed stands of tropical rainforest on the planet, in addition to large wetlands. The basin ends where the river empties its load in the Gulf of Guinea on the Atlantic Ocean. The climate is equatorial tropical, with two rainy seasons including very high rainfalls, and high temperature year round. The basin is home to the endangered western lowland gorilla.

The basin was the watershed of the Congo River populated by pygmy peoples, and eventually Bantu peoples migrated there and founded the Kingdom of Kongo. Belgium, France, and Portugal later established colonial control over the entire region by the late 19th century. The General Act of the Berlin Conference of 1885 gave a precise definition to the "conventional basin" of the Congo, which included the entire actual basin plus some other areas. The General Act bound its signatories to neutrality within the conventional basin, but this was not respected during the First World War.

Congo River Rapids (Alton Towers)

Congo River Rapids was a river rapids ride made by Intamin. It was located in the Katanga Canyon area of Alton Towers in Staffordshire, England.

The rapids course came close to the Runaway Mine Train as it passed through the tunnel. It featured twin waterfalls, and rafts passed between the two waterfalls.

Congo River Rapids shared its name with a ride at Busch Gardens Tampa in Tampa, Florida, but it has different layout.

Geography of the Democratic Republic of the Congo

The Democratic Republic of the Congo forms part of the Congo River Basin, which covers an area of almost 1,000,000 square kilometres (390,000 sq mi). The country's only outlet to the Atlantic Ocean is a narrow strip of land on the north bank of the Congo River.

The vast, low-lying central area is a plateau-shaped basin sloping toward the west, covered by tropical rainforest and criss-crossed by rivers, a large area of this has been categorized by the World Wildlife Fund as the Central Congolian lowland forests ecoregion. The forest center is surrounded by mountainous terraces in the west, plateaus merging into savannas in the south and southwest.

Dense grasslands extend beyond the Congo River in the north. High mountains of the Ruwenzori Range (some above 5,000 m or 16,000 ft) are found on the eastern borders with Rwanda and Uganda (see Albertine Rift montane forests for a description of this area).

Kasai River

The Kasai River (called Cassai in Angola) is a tributary (left side) of the Congo River, located in Central Africa. The river begins in central Angola and flows to the east until it reaches the border between Angola and the Democratic Republic of the Congo (DRC), where it turns north and serves as the border until it flows into the DRC. From Ilebo, between the confluences with Lulua river and Sankuru river, the Kasai river turns to a westerly direction. The lower stretch of the river from the confluence with Fimi river, is known as the Kwa(h) River, before it joins the Congo at Kwamouth northeast of Kinshasa. The Kasai basin consists mainly of equatorial rainforest areas, which provide an agricultural land in a region noted for its infertile, sandy soil. It is a tributary of Congo river and diamonds are found in this river. Around 60% of diamonds in Belgium go from Kasai river for cutting and shaping.


Kinshasa (; French: [kinʃasa]; formerly Léopoldville (French: Léopoldville or Dutch Leopoldstad )) is the capital and the largest city of the Democratic Republic of the Congo. The city is situated alongside the Congo River.

Once a site of fishing and trading villages, Kinshasa is now a megacity with an estimated population of more than 11 million. It faces Brazzaville, the capital of the neighbouring Republic of the Congo, which can be seen in the distance across the wide Congo River, making them the world's second-closest pair of capital cities after Rome and Vatican City. The city of Kinshasa is also one of the DRC's 26 provinces. Because the administrative boundaries of the city-province cover a vast area, over 90 percent of the city-province's land is rural in nature, and the urban area occupies a small but expanding section on the western side.Kinshasa is Africa's third-largest urban area after Cairo and Lagos. It is also the world's largest Francophone urban area (surpassing Paris in population), with French being the language of government, schools, newspapers, public services, and high-end commerce in the city, while Lingala is used as a lingua franca in the street. Kinshasa hosted the 14th Francophonie Summit in October 2012.Residents of Kinshasa are known as Kinois (in French and sometimes in English) or Kinshasans (English). The indigenous people of the area include the Humbu and Teke.

Lomami River

The Lomami River is a major tributary of the Congo River in the Democratic Republic of the Congo. The river is approximately 1,280 kilometres (800 mi) long. It flows north, west of and parallel to the upper Congo.

The Lomami rises in the south of the country, near Kamina and the Congo–Zambezi divide. It flows north through Lubao, Tshofa, Kombe, Bolaiti, Opala, and Irema before joining the Congo at Isangi.

Henry Morton Stanley reached the confluence of the two rivers on 6 Jan. 1877, "the affluent Lumami, which Livingstone calls 'Young's river,' entered the great stream, by a mouth 600 yards wide, between low banks densely covered with trees."In October 1889 M. Janssen, Governor-General of the Congo State, explored the Lomani river upstream from Isangi on the Ville de Bruxelles. After steaming for 116 hours he was stopped by rapids at a latitude of 4°27'2" S.The river has lent its name to a number of biological species, including the monkey Cercopithecus lomamiensis and the flowering plant Pavetta lomamiensis.

Lualaba River

The Lualaba River flows entirely within the eastern Democratic Republic of the Congo. It is the greatest river source (headstream) of the Congo River by volume of water. The Lualaba is 1,800 kilometres (1,100 mi) long. Its headwaters are in the country's far southeastern corner near Musofi and Lubumbashi in Katanga Province, next to Zambia. The Chambeshi River is the longest river source (headstream) of the Congo.


Matadi is the chief sea port of the Democratic Republic of the Congo and the capital of the Kongo Central province. It has a population of 245,862 (2004). Matadi is situated on the left bank of the Congo River, 148 km (92 mi) from the mouth and 8 km (5.0 mi) below the last navigable point before the rapids that make the river impassable for a long stretch upriver. It was founded by Sir Henry Morton Stanley in 1879.

Pool Department

Pool is a department of the Republic of the Congo in the southeastern part of the country. It borders the departments of Bouenza, Lékoumou, and Plateaux, and internationally, the Democratic Republic of the Congo. It also surrounds the commune district of the national capital, Brazzaville. The regional capital is Kinkala. Principal towns include Boko, Kindamba and Mindouli. In the early 2000s, the Pool region was the home of a low-level insurgency led by Pasteur Ntumi. The region is named after the Pool Malebo (formerly Stanley Pool), which is a particularly wide stretch of the Congo River.

Pool is divided into six districts:

Boko District

Kindamba District

Kinkala District

Mayama District

Mindouli District

Ngabe District

Pool Malebo

The Pool Malebo, formerly Stanley Pool, also known as Lake Nkunda by local indigenous people in pre-colonial times, is a lake-like widening in the lower reaches of the Congo River. The former name Stanley Pool was named after early European explorer and journalist Henry Morton Stanley.


Soyo (formerly known as Santo António do Zaire) is a city located in the province of Zaire in Angola, at the mouth of the Congo river. Soyo recently became the largest oil-producing region in the country, with an estimate of 1,200,000 barrels per day (190,000 m3/d).

Ubangi River

The Ubangi River (), also spelled Oubangui, is the largest right-bank tributary of the Congo River in the region of Central Africa. It begins at the confluence of the Mbomou and Uele Rivers and flows west, forming the border between Central African Republic (CAR) and Democratic Republic of the Congo. Subsequently, the Ubangi bends to the southwest and passes through Bangui, the capital of the CAR, after which it flows south – forming the border between Democratic Republic of the Congo and Republic of Congo. The Ubangi finally joins the Congo River at Liranga.

The Ubangi's length is about 1,060 kilometres (660 mi). Its total length with the Uele, its longest tributary, is 2,270 kilometres (1,410 mi). The Ubangi's drainage basin is about 772,800 square kilometres (298,400 sq mi). Its discharge at Bangui ranges from about 800 cubic metres per second (28,000 cu ft/s) to 11,000 cubic metres per second (390,000 cu ft/s), with an average flow of about 4,000 cubic metres per second (140,000 cu ft/s).Together with the Congo River, it provides an important transport artery for river boats between Bangui and Brazzaville.

From its source to 100 kilometres (62 mi) below Bangui, the Ubangi defines the boundary between the Central African Republic and the Democratic Republic of the Congo (DRC). Thereafter, it forms the boundary between the DRC and the Republic of Congo until it empties into the Congo River.

In the 1960s, a plan was proposed to divert waters from the Ubangi to the Chari River which empties into Lake Chad. According to the plan, the water from the Ubangi would revitalize that lake and provide a livelihood in fishing and enhanced agriculture to tens of millions of central Africans and Sahelians. Inter-basin water transfer schemes were proposed in the 1980s and 1990s by Nigerian engineer J. Umolu (ZCN) and the Italian firm Bonifica (Transaqua). In 1994, the Lake Chad Basin Commission (LCBC) proposed a similar project, and at a March 2008 summit the heads of state of the LCBC member countries committed to the diversion project. In April 2008, the LCBC advertised a request for proposals for a feasibility study.
