Lake Victoria
With
a surface area of 68,800 sq km (26,600 sq mi), Lake Victoria is Africa’s
largest lake. In addition, it's the largest tropical lake in the world, and the
planet's second largest freshwater lake. Only North America's Lake Superior is
larger.
An
irregular quadrilateral in shape, its shores, save on the west, are deeply
indented. Its greatest length from north to south is 210 miles (337 km), its
greatest breadth 150 miles (240 km). Its coastline exceeds 2,000 miles (3,220
km). Its waters fill a shallow depression in the centre of the great plateau
that stretches between the Western and Eastern Rift Valleys. The lake’s surface
is 3,720 feet (1,134 metres) above sea level, and its greatest ascertained
depth is 270 feet (82 metres). Many archipelagos are contained within the lake,
as are numerous reefs, often just below the surface of the clear waters. Lake
Victoria has more than 200 species of fish, of which the Tilapia is the most
economically important. The lake’s basin area covers 92,240 square miles
(238,900 square km).
The
lake’s shores vary in aspect. The lake’s southwestern coast is backed by
precipices 300 feet (90 metres) high, which give way on the western coast to
papyrus and ambatch swamps marking the delta of the Kagera River. The lake’s
deeply indented northern coast is flat and bare. A narrow channel leads into
the Kavirondo Gulf, which has an average width of 16 miles (25 km) and extends
for 40 miles (64 km) eastward to Kisumu, Kenya. The Ugandan cities of Kampala
and Entebbe lie along or near the northern coast. At the lake’s southeastern
corner is Speke Gulf, and at the southwestern corner Emin Pasha Gulf. Of the
numerous islands in the lake, Ukerewe, north of Speke Gulf, is the largest,
with wooded hills rising 650 feet (200 metres) above the lake. It is densely
populated. At the lake’s northwestern corner are the 62 islands of the Sese
archipelago, some of them of striking beauty.
The
Kagera River, the largest and most important of the lake affluents, enters the
western side of Lake Victoria just north of latitude 1° S. The only other river
of note entering from the west is the Katonga, north of Kagera. The lake’s only
outlet is the Victoria Nile, which exits from the northern coast.
The
search by Europeans for the source of the Nile led to the sighting of the lake
by the British explorer John Hanning Speke in 1858. Formerly known to the Arabs
as Ukerewe, the lake was named by Speke in honour of Queen Victoria of England.
A detailed survey of the lake was made by Sir William Garstin in 1901. Plans
for gradually raising the level of the lake’s waters were completed in 1954
with the construction of the Owen Falls Dam (now the Nalubaale Dam) on the Victoria
Nile at Jinja, Uganda. The dam provides hydroelectric power on a large scale
and made the lake a vast reservoir. A second dam, Kiira, was later constructed
0.6 mile (1 km) from Nalubaale. It was completed in 1999 and began producing
hydroelectric power the next year.
The
Lake Victoria region is one of the most densely populated in Africa; within 50
miles (80 km) of its shores live several million people, nearly all
Bantu-speaking. There are local steamer services around the lake.
