Lake Victoria is one of the African Great Lakes. The lake was named after Queen Victoria of the United Kingdom, by John Hanning Speke, the first European to discover this lake.
With a surface area of 68,800 square kilometers (26,600 sq mi), Lake Victoria is Africa’s largest lake by area, and it is the largest tropical lake in the world. Lake Victoria is the world's 2nd largest freshwater lake by surface area; only Lake Superior in North America is larger. In terms of its volume, Lake Victoria is the world's ninth largest continental lake, and it contains about 2,750 cubic kilometers (2.2 billion acre-feet) of water.
Lake Victoria receives most of its water from direct precipitation or from thousands of small streams. The largest stream flowing into this lake is the Kagera River, the mouth of which lies on the lake's western shore. Two rivers leave the lake, the White Nile (known as the "Victoria Nile" as it leaves the lake), flows out at Jinja, Uganda on the lake's north shore, and the Katonga River flows out at Lukaya on the western shore connecting the lake to Lake George.
Lake Victoria occupies a shallow depression in Africa and has a maximum depth of 84 m (276 ft) and an average depth of 40 m (130 ft). Its catchment area covers 184,000 square kilometers (71,040 sq mi). The lake has a shoreline of 4,828 km (3,000 mi), with islands constituting 3.7% of this length, and is divided among three countries: Kenya (6% or 4,100 km2/1,600 sq mi), Uganda (45% or 31,000 km/12,000 sq mi) and Tanzania(49% or 33,700 km2/13,000 sq mi)
