Lake Victoria, in the countries of Kenya, Tanzania, and Uganda, is the largest lake in Africa and the world’s second largest freshwater lake, after Lake Superior on the U.S. Canadian border.
Lake Victoria covers 26,828 square miles (69,484 sq km), about the same area as the country of Ireland.
Lake Tanganyika, also in eastern Africa and touching the countries of Zaire, Tanzania, and Zambia, is the longest freshwater lake in the world.
It is 420 miles (680 km) long and more than 4,700 feet (1,430 m) deep.
Like many other long, deep lakes in this part of Africa, it was formed in the bottoms of rift valleys.
