The Mono River is the major river of eastern Togo.
Approximately 400 km (250 mi) long, and draining a basin of about 20,000 km2 (7,700 sq mi), it rises between the town of Sokodé and the border with Benin, and flows south. Along the southern portion of the river towards its mouth, it forms the international boundary between Togo and Benin. The river drains into the Bight of Benin through an extensive system of brackish water lagoons and lakes, including Lake Togo. [1] Only the part of the river nearest its mouth is navigable. Most of the river's basin on the upper tableland is cultivated for maize, yams, rice, cotton and cassava. [2]
The river is dammed 160 km (99 mi) from its mouth by the Nangbeto Dam, a partnership between Benin and Togo completed in 1987. Studies have reported economic benefits from the dam, including tourism and fishing in the lake behind it. The dam's construction displaced between 7,600 and 10,000 people, however, and studies indicate that it has substantially modified the ecology of the lagoon system at the river's mouth by reducing the natural seasonal fluctuations in river flow. A second dam project, Adjarala Dam, was proposed to be built on the river between Nangbeto and the river's mouth during the 1990s [3] but did not receive financing until 2017 when the China-Africa Development Fund agreed to support the project. [4] The dam's construction is part of the government's plan to increase Benin's domestic power generation capacity from 20 to 70% as most of Togo and Benin's electricity currently needs to be imported from the Akosombo Dam in Ghana. [5]
About 35 km (22 mi) from its mouth, there are six series of rapids. Below this, the river becomes slow-moving and flows over a swampy floodplain, and there is a large area of contiguous wetland in both Togo and Benin. This area has a rich growth of reeds, sedges and grasses, and manatees, crocodiles and hippopotamus occur in the river. [6]
Ghana is a West African country in Africa, along the Gulf of Guinea.
Togo is a small Sub-Saharan state, comprising a long strip of land in West Africa. Togo's geographic coordinates are a latitude of 8° north and a longitude of 1°10′ east. It is bordered by three countries: Benin to the east, with 644 km (400 mi) of border; Burkina Faso to the north, with 126 km (78 mi) of border; and Ghana, with 877 km (545 mi) of border. To the south Togo has 56 km (35 mi) of coastline along the Bight of Benin of the Gulf of Guinea in the North Atlantic Ocean. Togo stretches 579 km (360 mi) north from the Gulf and is only 160 km (99 mi) wide at the broadest point. In total, Togo has an area of 56,785 km2 (21,925 sq mi), of which 54,385 km2 (20,998 sq mi) is land and 2,400 km2 (927 sq mi) is water.
The Volta River is the main river system in the West African country of Ghana. It flows south into Ghana from the Bobo-Dioulasso highlands of Burkina Faso. The main parts of the river are the Black Volta, the White Volta, and the Red Volta. In the northwest, the Black Volta forms the international borders between the Ivory Coast, Ghana, and Burkina Faso. The Volta flows southward along the Akwapim-Togoland highlands, and empties into the Atlantic Ocean at the Gulf of Guinea at Ada Foah. One of its smaller tributaries, the Oti River, enters Ghana from Togo in the east. The Volta River has been dammed at Akosombo for generating hydroelectricity. The reservoir named Lake Volta stretches from Akosombo Dam in the south to the northern part of the country, and is the largest man-made reservoir by area in the world.
Benin, a narrow, key-shaped, north–south strip of land in West Africa, lies between the Equator and the Tropic of Cancer. Its latitude ranges from 6°30′ N to 12°30′ N and its longitude from 1° E to 3°40′ E. It is bounded by Togo to the west, Burkina Faso and Niger to the north, Nigeria to the east, and the Bight of Benin to the south.
The Zambezi is the fourth-longest river in Africa, the longest east-flowing river in Africa and the largest flowing into the Indian Ocean from Africa. Its drainage basin covers 1,390,000 km2 (540,000 sq mi), slightly less than half of the Nile's. The 2,574 km (1,599 mi) river rises in Zambia and flows through eastern Angola, along the north-eastern border of Namibia and the northern border of Botswana, then along the border between Zambia and Zimbabwe to Mozambique, where it crosses the country to empty into the Indian Ocean.
The White Nile is a river in Africa, the minor of the two main tributaries of the Nile, the larger being the Blue Nile. The name "White" comes from the clay sediment carried in the water that changes the water to a pale color.
The Tigris–Euphrates river system is a large river system in Western Asia that discharges into the Persian Gulf. Its principal rivers are the Tigris and Euphrates, along with smaller tributaries.
The Neman,Niemen or Nemunas is a river in Europe that rises in central Belarus and flows through Lithuania then forms the northern border of Kaliningrad Oblast, Russia's western exclave, which specifically follows its southern channel. It drains into the Curonian Lagoon, narrowly connected to the Baltic Sea. The 937 km (582 mi) long Neman is a major Eastern European river. It flows generally west to Grodno within 12 kilometres (7.5 mi) of the Polish border, north to Kaunas, then westward again to the sea.
The Akosombo Dam, also known as the Volta Dam, is a hydroelectric dam on the Volta River in southeastern Ghana in the Akosombo gorge and part of the Volta River Authority. The construction of the dam flooded part of the Volta River Basin and led to the subsequent creation of Lake Volta. Lake Volta is the largest man-made lake in the world by surface area. It covers 8,502 square kilometres (3,283 sq mi), which is 3.6% of Ghana's land area. With a volume of 148 cubic kilometers, Lake Volta is the world's third largest man-made lake by volume; the largest being Lake Kariba which contains 185 cubic kilometers of water.
The Kafue River is the longest river lying wholly within Zambia at about 1,576 kilometres (979 mi) long. Its water is used for irrigation and for hydroelectric power. It is the largest tributary of the Zambezi, and of Zambia's principal rivers, it is the most central and the most urban. More than 50% of Zambia's population live in the Kafue River Basin and of these around 65% are urban.
The Oti River or Pendjari River is an international river in West Africa. It rises in Benin, forms the border between Benin and Burkina Faso, flows through Togo, and joins the Volta River in Ghana.
The Komati River, also known as the Inkomati River or Incomati River, is a river in South Africa, Eswatini and Mozambique. Originating in north-western Eswatini, it is joined by the Crocodile River in the Lebombo Mountains, enters far south-western Mozambique below the border town of Komatipoort, and enters the Indian Ocean around 24 km (15 mi) north-east of Maputo.
The Rokel River is the largest river in the Republic of Sierra Leone in West Africa. The river basin measures 10,622 km2 (4,101 sq mi) in size, with the drainage divided by the Gbengbe and Kabala hills and the Sula Mountains. The estuary which extends over an area of 2,950 km2 (1,140 sq mi) became a Ramsar wetland site of importance in 1999.
The Togo Mountains is a mountain range which stretches across the central region of the West African country of Togo and across the eastern and western borders of that country into Ghana and Benin. In Ghana, the range is also known as the Akwapim Hills, and in Benin it is also known as the Atakora Mountains. Part of the range is associated with the country of Niger, where the W National Park is found. The African wild dog, Lycaon pictus, was historically found in this region but may now be extirpated from this locale.
The Ebro is a river of the north and northeast of the Iberian Peninsula, in Spain. It rises in Cantabria and flows 930 kilometres (580 mi), almost entirely in an east-southeast direction. It flows into the Mediterranean Sea, forming a delta in the Terres de l'Ebre region, in southern Catalonia. In the Iberian peninsula, it ranks second in length after the Tagus and second in discharge volume, and drainage basin, after the Douro. It is the longest river entirely within Spain; the other two mentioned flow into Portugal. It is also the second-longest river in the Mediterranean basin, after the Nile.
The Southern Ewaso Ng'iro is a river in the Great Rift Valley in Kenya. It plays an important role in the ecology of Lake Natron, the main regular breeding site for near-threatened lesser flamingos. Changes to land use in the river's headwaters or in the marshes before the river enters the lake could have a serious impact on this species.
Kellogg Creek is a tributary, about 4.5 miles (7.2 km) long, of the Willamette River in the Portland metropolitan area of the U.S. state of Oregon. It begins near Lake Lenore in Johnson City and flows northwest to meet the river at Milwaukie. Kellogg Creek is joined about midway along its course by Mount Scott Creek, its major tributary, which enters the main stem near North Clackamas Central Park.
The Yala River is a river in western Kenya, a tributary of Lake Victoria. It generally flows fast over a rocky bed through a wide valley before joining the Nzoia River to form the Yala Swamp on the border of Lake Victoria. The land along its course is mostly cultivated or used for grazing, with relatively few remnants of the original forest. Soil erosion is visible throughout the river basin, particularly in the lower parts. Projects are underway to exploit the river for hydroelectricity.
Tététou is a Togolese municipality located in the Haho Prefecture, in the Plateaux Region, southeastern Togo. The municipality is situated in the center of the protected forest of Tététou.
