Top 5 Dams Functioning In Africa
Africa’s need for water has not been exempt from the rise in population and the drive for industrial growth.
A recent count put the number of dams in Africa up high as this has become a major source of generating power.
There are 980 large dams in total, with approximately 589 in South Africa, the majority of which are located along the Nile.
Dams are simply obstructions constructed to stop or limit the flow of surface water or underground streams.
They are built for significant reasons, such as relieving flooding, producing hydropower (electricity), putting away water for agriculture (irrigation and fishing), and domestic utilization, etc.
Let’s take a look at the five top dams in Africa are listed below:
List of the Top 5 Dams in Africa
1. Grand Renaissance Dam (Ethiopia)
The first one on our list is the Great Renaissance Dam!
The Grand Ethiopian Renaissance Dam, earlier known as the Millennium Dam, is a gravity dam on the Blue Nile River in Ethiopia under development since 2011.
With a capacity of 6,450MW, it will be Africa’s largest hydropower project. It is about 750 kilometers northwest of Ethiopia’s capital, Addis Ababa, and 40 kilometers from Sudan.
The development of the $4.5bn hydropower project began in April 2011. The Ethiopian Government is executing the undertaking through the Ethiopian Electric Power (EEP).
The hydropower project is relied upon to produce 15,128GWh of force a year when operational, expanding the power limit of Ethiopia by multiple times.

2. Katse Arch Dam (South Africa)
Second, on the list of the top dams in Africa is the katse Arch Dam!
This is one of the most ambitious engineering projects ever undertaken in South Africa. Katse is the continent’s second-largest double-curvature arch dam.
The Katse Dam is about 710-metres long and 185-meters in height. It impounds a deep, squiggly reservoir that extends back more than 30km along the Malibamat’so River.
Katse Dam (reputedly named after a wealthy local farmer, Katse) was constructed in the early 1990s as the centerpiece of the Lesotho Highlands Water Project (LHWP).
Water from Katse is funneled through an 82km underground tunnel into the Ash River near Clarens, South Africa.
From where it flows along a succession of natural waterways into the Vaal Dam, the main reservoir in the industrialized and densely populated South African province of Gauteng.
3. The Aswan High Dam (Egypt / Sudan)
Third on the list is the Aswan High Dam!
The Aswan High Dam is a stone-filled dam situated on the northern line between Egypt and Sudan. This magnificent was developed in 1898 under the direction of Sir William Willcocks.
The dam was finished in 1902 and was raised twice somewhere in the range of 1907 and 1912, trailed by a further two somewhere in the range of 1929 and 1933 to additionally ease the Nile from flooding.
With a supply limit of 132km3, it provides water to approximately 33,600km2 of water system land.
It meets Egypt’s and Sudan’s water system needs, controls flooding, produces, and aids in the improvement of Nile routes.
Egypt and Sudan agreed in 1959 that saw the assignment of 18.5 cubic kilometers of water to Sudan.
Nonetheless, the Aswan Low Dam was not sufficient to control the yearly flooding, which brought about building a higher dam in 1952.
4. The Cahora Bassa Dam (Mozambique)
fourth on our list of the top dams in Africa is the Cahora Bassa!
Cahora Bassa, also known as Cabora Bassa, is a curved dam and hydroelectric power station on the Zambezi River in western Mozambique.
The dam, situated around 80 miles (125 km) northwest of Tete, is 560 feet (171 m) high and 994 feet (303 m) wide at the peak.
It is anything but a volume of 667,000,000 cubic yards (510,000,000 cubic m). The dam appropriates Lake Cahora Bassa, which is 150 miles (240 km) long and 19 miles (31 km) wide at its vastest point.
The lake has a capacity of 51,075,000 sections of land feet (63,000,000,000 cubic meters) and extends to the Zambia-Mozambique border.
A consortium of Portuguese, German, British, and South African organizations worked on the dam. The development of the dam started in 1969 and was finished in 1974.
Cahora Bassa dam supplies power to South Africa over an 870-mile-(1,400-kilometer-) long, double 530-kilowatt transmission line and to Maputo, Tete, and the Moatize coal mineshafts close to the town of Tete.
Force transmission to South Africa was intruded on during the Mozambican civil conflict, but it continued during the mid-1990s.
5. Gibe 111 Dam (Ethiopia)
Gibe III is the third phase of the Gibe-Omo hydroelectric course, which includes Gibe I and Gibe II (both in operation) and Koysha (under development).
The Ethiopian government has launched a massive program to significantly improve the country’s food supply. Scoff III incorporates the world’s most elevated RCC gravity dam, over 250 m high.
With his record-breaking stature, the dam included significant specialized endeavors, and it has ended up being probably the greatest test undertaken by our architects to date.
The enormous spillway of the dam is anything but a flood peak separated into seven bayous, It is also constrained by outspread doors, and flip cans on the chute intended for somewhat disseminating the energy in the air.
In the streambed, a pre-unearthed plunge pool is predicted between the d/s toe of the dam and the force to be reckoned with.
Each door has complete freedom of movement, ensuring exceptional adaptability for activity and support.
Two center outlets are inserted in the dam body. These are intended to permit the control of the supply seizure and are estimated to adapt to the wet season flood discharge, as indicated by the suggestions of the ESIA consideration.
A few massive actual pressure-driven models demonstrated the activity of these massive water-powered works.
Remarkable water-powered conditions were also replicated, and the results of these tests demonstrated that the spillway could function in a variety of antagonistic conditions.
