Africa's jaw-dropping 250-mile-long man-made lake that's the world's largest
The project came at a huge cost with entire forests submerged and 78,000 people forced to relocate.
When people think of massive man-made projects, artificial lakes aren’t usually the first thing that comes to mind. Skyscrapers, bridges, and tunnels tend to dominate discussions about amazing engineering. But while these structures often steal the spotlight, there is something fascinating about the world’s largest man-made lake based on surface area.
Created by flooding entire villages and forests, this enormous reservoir completely reshaped the landscape, forcing thousands of people to relocate while generating power and transforming transportation in the region. Lake Volta, located in Ghana, spans a staggering 8,502 square kilometres - about 3.6% of the country’s total land area.
Stretching approximately 250 miles (400km) from north to south, it was formed in the 1960s when the Akosombo Dam was built to harness the power of the Volta River.
The dam generates 912 megawatts of electricity, supplying most of Ghana’s power and even exporting energy to neighbouring countries such as Togo and Benin.
But the creation of the lake came at a significant cost. Entire forests were submerged, and 78,000 people were forced to relocate when 15,000 homes and 740 villages were flooded.
The project aimed to modernise the region and boost fishing, but it also disrupted traditional farming and livelihoods.
Despite these challenges, Lake Volta has become a crucial waterway, providing a cheap transport link between Ghana’s northern savanna and the coast.

One of the lake’s most striking features is its islands. Dodi, Dwarf, and Kporve islands sit within its huge expanse, with Dodi Island attracting tourists for boat cruises.
The lake’s western shore is also home to Digya National Park, a protected area with rich biodiversity.
In addition to tourism and transportation, Lake Volta has become the site of an unusual industry - harvesting submerged timber.
Logging companies extract tropical hardwood from the trees that were swallowed when the lake was created, producing a supply of environmentally sustainable wood without cutting down existing forests.
