The Volta River is the main river system in the West African country of Ghana. It flows south into Ghana from 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 Akwapim-Togoland highlands, and it empties into the Atlantic Ocean at the Gulf of Guinea at Ada Foah. It has a smaller tributary river, the Oti, which enters Ghana from Togo in the east. The Volta River has been dammed at Akosombo for the purpose of 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. [4]

Contents

Volta was named by the Portuguese, meaning twist or turn.

The reservoir

Lake Volta is a reservoir impounded by the Akosombo Dam on the lower Volta River in southern Ghana. It is one of the largest reservoirs in the world. It extends from the Akosombo Dam in southeastern Ghana to the town of Yapei in the Central Gonja District, Northern Region of Ghana, some 400 kilometres (250 mi) to the north.

The dam's power plant generates electricity for the Volta River Authority, and the reservoir also provides water transport routes. It may be a resource for irrigation and fish farming.

The depth of the river is about 45 feet (14 m) below Lake Volta. The Volta River is crossed by the Adome Bridge just below the Akosombo Dam.

History

The Volta River was named by Portuguese gold traders in Ghana. It was their farthest extent of exploration before returning (volta is Portuguese for "twist" or "turn"). [5] "River of return" (perhaps because it was where ships turned around and headed for home) or “river of the bend”, in reference to its curved course. [5] [6]

Angara River in Irkutsk Oblast and Krasnoyarsk Krai, south-east Siberia, Russia

The Angara is a major river in Siberia, which traces a course through Russia's Irkutsk Oblast and Krasnoyarsk Krai. It drains out of Lake Baikal and is the headwater tributary of the Yenisey. It is 1,849 kilometres (1,149 mi) long, and has a drainage basin of 1,039,000 square kilometres (401,000 sq mi). It was formerly known as the Lower or Nizhnyaya Angara. Below its junction with the Ilim, it was formerly known as the Upper Tunguska and, with the names reversed, as the Lower Tunguska.

Songhua River River in China and North Korea

The Songhua River is one of the primary rivers of China, and the longest tributary of the Amur. It flows about 1,434 kilometres (891 mi) from the Changbai Mountains on the China–North Korea border through China's northeastern Jilin and Heilongjiang provinces.

Akosombo Dam Dam in Akosombo, Ghana

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. The flooding that created the Lake Volta reservoir displaced many people and had a significant impact on the local environment. 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 is located between Zimbabwe and Zambia in Southern Africa and contains 185 cubic kilometers of water.

Paraná River River in South America

The Paraná River is a river in south Central South America, running through Brazil, Paraguay, and Argentina for some 4,880 kilometres (3,030 mi). It is second in length only to the Amazon River among South American rivers. The name Paraná is an abbreviation of the phrase "para rehe onáva", which comes from the Tupi language and means "like the sea". It merges first with the Paraguay River and then farther downstream with the Uruguay River to form the Río de la Plata and empties into the Atlantic Ocean.

Black Volta

The Black Volta or Mouhoun is a river that flows through Burkina Faso flowing about 1,352 km (840 mi) to the White Volta in Dagbon, Ghana. The source of the Black Volta is in the Cascades Region of Burkina Faso, close to Mount Tenakourou, the highest point of the country. Further downstream it forms part of the border between Ghana and Côte d'Ivoire and Burkina Faso. Within Ghana, it forms the border between the Savannah Region and the Bono Region. The Bui Dam is built on the river in Ghana. The river bisects Bui National Park in Ghana.

Lake Volta Largest artificial reservoir, in Ghana

Lake Volta, the largest artificial reservoir in the world based on surface area, is contained behind the Akosombo Dam which generates a substantial amount of Ghana's electricity. It is completely within the country of Ghana and has a surface area of 8,502 square kilometres. It extends from Akosombo in the south to the northern part of the country.

White Volta Headstream of the Volta River

The White Volta or Nakanbé is the headstream of the Volta River, Ghana's main waterway. The White Volta emerges in northern Burkina Faso, flows through North Ghana and empties into Lake Volta in Ghana. The White Volta's main tributaries are the Black Volta and the Red Volta.

Oti River

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.

Río Negro (Uruguay)

The Río Negro is the most important river in Uruguay. It originates in the southern highlands of Brazil, just east of Bagé, and flows west across the entire width of Uruguay to the Uruguay River. The course of the Río Negro across Uruguay effectively divides the south of the country from the north. The Río Negro's principal tributaries are Yí River and Tacuarembó River.

Bui Dam Dam in On the border of the Savannah Region and the Bono Region "`UNIQ--ref-00000000-QINU`"

The Bui Dam is a 400-megawatt (540,000 hp) hydroelectric project in Ghana. It is built on the Black Volta river at the Bui Gorge, at the southern end of Bui National Park. The project is a collaboration between the government of Ghana and Sino Hydro, a Chinese construction company. Construction on the main dam began in December 2009. Its first generator was commissioned on 3 May 2013, and the dam was inaugurated in December of the same year.

Electricity sector in Ghana

Ghana generates electric power from hydropower, fossil-fuel, and renewable energy sources. Electricity generation is one of the key factors in order to achieve the development of the Ghanaian national economy, with aggressive and rapid industrialisation; Ghana's national electric energy consumption was 265 kilowatt hours per capita in 2009.

Kpong Dam Dam in Akuse

The Kpong Dam, also known as the Akuse Dam, is a hydroelectric power generating dam on the lower Volta River near Akuse in Ghana. It is owned and operated by Volta River Authority. It was constructed between 1977 and 1982. Its power station has a capacity of 148 megawatts (198,000 hp) with all four units running, though the total nameplate capacity is 160 megawatts (210,000 hp).

North Fork Kings River

The North Fork Kings River is a 40.3-mile (64.9 km) tributary of the Kings River, in the U.S. state of California. The river's main stem is entirely within Fresno County, and its watershed drains about 387 square miles (1,000 km2) of the southern Sierra Nevada mountain range.

Madden Dam

The Madden Dam, completed in 1935, impounds the Chagres River in Panama to form Lake Alajuela, a reservoir that is an essential part of the Panama Canal watershed. The lake has a maximum level of 250 feet (76 m) above sea level. It can store one third of the canal's annual water requirements for the operation of the locks. Since the reservoir is not part of the navigational route, there are fewer restrictions on its water level.
