Lake Albert, also called Albert Nyanza, is one of the sources of the Nile River. It lies between Uganda and the Democratic Republic of the Congo. It covers about 1,640 square miles (4,248 square kilometers). It is about 100 miles (160 kilometers) long and about 20 miles (32 kilometers) wide. Lake Edward flows into Lake Albert from the south through the Semliki River. Waters from Lake Victoria reach Lake Albert by way of the Victoria Nile River after flowing over Murchison Falls, also known as Kabalega Falls. The waters of Lake Albert drain north and form the Albert Nile. Lake Albert was named for the husband of Queen Victoria of the United Kingdom.
