Victoria, Lake (redirected from Lake Victoria)

Victoria, Lake, or Victoria Nyanza (nēăn`zə, nī–), largest lake of Africa and the world's second largest freshwater lake, c.26,830 sq mi (69,490 sq km), E central Africa, on the Uganda-Tanzania-Kenya border. Lake Victoria (c.255 mi/410 km long and c.155 mi/250 km wide) occupies a shallow depression (c.250 ft/75 m deep) on the Equatorial Plateau (alt. 3,725 ft/1,135 m) between two arms of the Great Rift Valley. It has an irregular shoreline and many small islands. Numerous streams, including the Kagera River, feed Lake Victoria, which is one of the chief headwater reservoirs of the Nile; the Victoria Nile drains the lake to the north. At Owen Falls Dam on the Victoria Nile the lake's waters are used to generate hydroelectricity. The lake basin is densely populated and intensely cultivated, and the lake is an important fishery, but fish stocks and diversity have declined since the 1980s as a result of overfishing and the introduction of the Nile perch. The lake has also suffered uncontrolled water hyacinth proliferation. Ships regularly call at lakeside towns, including Entebbe, Mwanza, Bukoba, and Kisumu. The first European to see Lake Victoria (originally called Ukerewe) was John Speke, the British explorer, in 1858; Henry Stanley explored the region in 1875.

Victoria, Lake

 or Victoria Nyanza

Largest lake in Africa and chief reservoir of the Nile River, east-central Africa. The southern half lies in Tanzania, the northern half in Uganda; it borders Kenya in the northeast. With an area of 26,828 sq mi (69,484 sq km), it is the second largest freshwater lake in the world (after Lake Superior in North America). It is about 210 mi (337 km) long, 150 mi (240 km) wide, and up to 270 ft (82 m) deep. Though the Kagera River is its largest tributary, the most important source of water for the lake is rainfall. Its only outlet is the Victoria Nile. John Hanning Speke, searching for the source of the Nile in 1858, was the first European to sight it. He named it for Queen Victoria; the Arabs had called it Ukerewe. Henry Morton Stanley circumnavigated it in 1875. It became a reservoir when the water level was raised after completion of Owen Falls Dam (now the Nalubaale Dam) in 1954.
