This low-oblique, southeast-looking photograph of Lake Volta (Volta Reservoir) provides a rare opportunity to see almost the entire reservoir with very few obscuring clouds. Lake Volta, one of the world’s largest manmade lakes, occupies a large area of southern Ghana—approximately 3275 square miles (8480 square kilometers) 280 miles (450 kilometers) upstream of the Akosombo Dam. Water impounded in this reservoir is used to irrigate crops, regulate the flow of water in Volta River, and generate hydroelectric power that supports an aluminum industry in Ghana. The Sun reflecting off the surface of the water (sunglint) helps identify and map the land-water boundaries.
