Lake Volta

Lake Volta is the largest artificial reservoir in the world by surface area. An artificial reservoir is a large body of water created by humans. This specific lake is located entirely within the country of Ghana. It sits near the Equator, about six degrees north of it. The lake stretches from the Akosombo Dam in the south toward the north. Its northernmost point is located near the town of Yapei.

The lake was created by the Akosombo Dam. This dam holds back two different rivers. These are the White Volta River and the Black Volta River. Before the dam was built, these two rivers met in the middle of the area. Now, they form the single Volta River. This river flows from the dam's powerhouse and spillways. It eventually reaches the Atlantic Ocean in southern Ghana. Several islands sit within the lake, such as Dodi, Dwarf, and Kporve. The western shore is home to Digya National Park.

History shows that the idea for the lake began in 1915. A geologist named Albert Ernest Kitson first conceived the plan. He wanted to use the river's energy to process bauxite. Bauxite is a mineral used to make aluminum. The idea became important again after World War II. This happened when Kwame Nkrumah became president of the Gold Coast. He wanted to modernize the land. Eventually, Kaiser Aluminum joined the project after long negotiations. This helped secure the necessary funding for construction.

The construction of the lake caused massive changes for local people. In 1964, the flooding of the area was very chaotic. The water covered 740 villages and 15,000 homes. This forced 78,000 people to relocate to new areas. The government tried to build 52 replacement towns. They hoped these towns would be models for modern living. However, the rush to finish caused significant hardship. Traditional farming and fishing practices were disrupted for many families. The project also led to a rise in water-related illnesses. These included malaria, schistosomiasis, and onchocerciasis.

Today, Lake Volta is vital to the economy of Ghana. The Akosombo Dam produces 912 MW of electricity. This power is used in Ghana and exported to nearby countries. These include Togo and Benin. This trade helps the country earn foreign exchange. The lake also serves as a major waterway. Ferries and cargo watercraft use it for transportation. Because the lake is in a tropical region, the water stays warm. This warmth supports a vast population of fish and large fisheries.

Tourism and new industries are growing around the lake. Dodi Island has been a major tourist site since 1961. In 2011, US$2.5 million was allocated to develop eco-tourism there. There is also a project to harvest submerged timber. This involves collecting high-value tropical hardwood from flooded forests. This method does not require cutting down new trees. It is considered an environmentally sustainable way to get wood. This project also helps by making navigation safer on the water.

There are complex social issues related to the lake's industry. An estimated 7,000 to 10,000 children work in the fishing industry. Some groups, like CNN, have described this work as slavery. Others, like academics Samuel Okyere and Betty Mensah, disagree. They suggest the children are actually apprentices. They note that many youths grow up to be self-sufficient fishermen. However, they also admit that many children may face exploitative work. Safety is also a concern for those traveling on the water. In October 2025, a boat accident near Kete Krachi killed 15 people. The Ghana Maritime Authority found the boat was grossly overloaded. They are now working to increase safety enforcement on the lake.
