Lake, central East Africa.
Located between Rwanda and the Democratic Republic of the Congo (Zaire), it occupies 1,040 sq mi (2,700 sq km), is 55 mi (90 km) long and 30 mi (48 km) wide, and has a maximum depth of 1,558 ft (475 m). Containing many islands, it was part of a larger body of water until volcanic outpourings along its northern shore created a dam that separated it from Lake Edward .
