58 free Lake Victoria trivia questions with answers — geography quiz, new questions added Sep 2026.
This Lake Victoria trivia quiz covers Africa's largest lake from every angle: geography, exploration, wildlife, fisheries and the people who live around it. The easy questions are the ones any geography fan can handle: which continent, which countries share it, which river flows out and which queen it was named for. From there the set moves into the numbers that surprise people, such as how shallow the lake really is, how much of its water arrives as rain, how many times it has dried up completely and how many people live in its catchment. The harder questions are for East Africa buffs and natural-history fans: the local names in Luganda and Dholuo, Speke's quarrel with Burton and his death on the eve of their debate, the newspaper that paid Stanley to circumnavigate the lake, the 500 haplochromine cichlid species and the predator introduced in the 1950s that wiped out hundreds of them, the water hyacinth invasion, the Ssese Islands, the agreed curve at the Jinja dam and the ferry sinkings that rank among Africa's worst maritime disasters. Every answer was checked against encyclopaedia entries for the lake, its explorers, its fish and its ferries before publishing, and the supporting sentence is stored with each question.

Q 01Lake Victoria's only outlet is the Nile, so where does the lake's water finally meet the sea?
The Mediterranean Sea
The Mediterranean Sea: the Nile carries the lake's water north, though most of the river's flow by then comes from Ethiopia rather than the lake.
Q 02Lake Victoria is usually ranked the world's second-largest freshwater lake by area, behind which lake?
Superior
Superior comes from the French for 'upper lake', a name about the lake's position rather than its size.
Q 03Which country holds the largest share of Lake Victoria's surface, about half?
Tanzania
Tanzania holds about half the lake, while Rwanda, a tempting guess, has no shoreline at all, though its rivers drain into the lake.
Q 04Some of whose ashes were scattered at Lake Victoria's Nile outlet?
Gandhi
Gandhi: a portion of his ashes went into the Nile here after his assassination in 1948, and the memorial on the spot has made it a place of pilgrimage for Indian visitors.
Q 05Which wildlife park's western corridor stretches almost to the shore of Lake Victoria?
Serengeti
Serengeti: the great wildebeest migration funnels west along this corridor each year, crossing the crocodile-filled Grumeti River, which drains into the lake.
Q 06Near which Ugandan town does the Nile leave Lake Victoria?
Jinja
Jinja sits at the lake's only outflow, where the water once spilled over a natural ridge of black rock that held the lake back.
Q 07Which future British prime minister, visiting Lake Victoria in 1907, urged harnessing its Nile outflow to drive turbines?
Winston Churchill
Winston Churchill, then a junior colonial minister, wrote that the Nile should begin its journey by leaping through a turbine; a dam finally made it do so nearly half a century later, during his last term as prime minister.
Q 08Which Ugandan leader backed the hijackers holding hostages at Entebbe, on Lake Victoria's shore, in 1976?
Idi Amin
Idi Amin, humiliated by the Israeli rescue, believed Kenya had helped, and hundreds of Kenyans living in Uganda were killed in reprisal.
Q 09Which insect-borne epidemic killed more than 200,000 people in Uganda, ravaging Lake Victoria's shores, in the early 1900s?
Sleeping sickness
Sleeping sickness, spread by tsetse flies, wiped out about two-thirds of the people in the worst-hit lakeshore areas.
Q 10Which American newspaper co-funded Stanley's 1874 expedition to Lake Victoria alongside London's Daily Telegraph?
The New York Herald
The New York Herald co-sponsored the trip, and Stanley's 1875 appeal for missionaries to Buganda brought the first Protestant ones there in 1877.
Q 11At which falls on Lake Victoria's northern shore did Stanley report the lake's outflow into the Nile?
Ripon Falls
Ripon Falls, named by Speke after a president of the Royal Geographical Society, vanished underwater when the Owen Falls Dam was completed in 1954.
Q 12Which explorer set out in 1866 to settle the Nile-source debate over Lake Victoria, but wandered into the Congo system?
David Livingstone
David Livingstone ignored Stanley's urging to leave Africa after their 1871 meeting and kept searching until his death in 1873.
Q 13How did Speke die in 1864, just before a planned debate on whether Lake Victoria fed the Nile?
A gunshot wound while shooting
Q 21Which European power ruled Lake Victoria's southern shore until the First World War?
Germany
Germany held it as part of German East Africa, and in June 1915 British troops crossed the lake in steamers to storm a German lakeside town and wreck its wireless station.
Q 22Where had the chimpanzees released on Lake Victoria's Rubondo Island in the 1960s been living beforehand?
European zoos and circuses
European zoos and circuses held them first, yet they adapted so well that their descendants were living wild without being fed some 40 years later.
Q 23Female cichlids in Lake Victoria mainly choose mates by what, a cue that murkier water is now hiding?
The males' colours
A gunshot wound while shooting killed Speke, so the much-anticipated debate never happened; an inquest ruled his death accidental.
Q 14Man-eating lions at Tsavo halted work in 1898 on which colonial railway heading to Lake Victoria?
Uganda Railway
The Uganda Railway saw hundreds of workers flee in terror until engineer John Henry Patterson shot both lions in December 1898.
Q 15From which side did Speke first sight Lake Victoria in 1858?
The south
The south: Speke saw only a small part of the lake's southern end, yet still judged it the likely head of the Nile.
Q 16Which world leader's father came from a village near the shores of Lake Victoria?
Barack Obama
Barack Obama's father left Kenya to study at the University of Hawaii, and it was there that he met Obama's mother.
Q 17Where does most of Lake Victoria's water come from?
Direct rainfall
Direct rainfall supplies about three-quarters or more of the lake's water, while all the rivers flowing in add only the rest.
Q 18Which river, fed from Rwanda and Burundi, is Lake Victoria's largest inflow?
The Kagera
The Kagera carries water from the Nile's most distant headwaters, so the great river's true starting point lies far upstream of Lake Victoria.
Q 19Roughly how deep is vast but shallow Lake Victoria at its deepest point?
80 metres
80 metres or so, because the lake simply fills a broad, shallow dip in a high plateau.
Q 20Which imaginary line crosses Lake Victoria?
The Equator
The Equator crosses the lake, yet at about 1,134 metres above sea level its shores stay milder than you might expect.
The males' colours: as the water clouds, females grow less choosy, and some once-separate species now interbreed.
Q 24Which is the only lake in the world with more fish species than Lake Victoria?
Malawi
Malawi is less than half Lake Victoria's size, yet it holds at least 700 cichlid species against Victoria's 500-plus.
Q 25Smoking Nile perch from Lake Victoria has been blamed for worsening which problem on the surrounding land?
Deforestation
Deforestation: the perch's oily flesh won't sun-dry like native fish, so it is often smoked, and the firewood that takes has been blamed for stripping trees.
Q 26Roughly how heavy can the Nile perch introduced into Lake Victoria grow?
200 kg
200 kg is roughly the top weight for this giant predator, which was blamed for driving hundreds of the lake's native fish species toward extinction.
Q 27How do Lake Victoria's fishermen lure shoals of tiny silver dagaa into their nets?
With floating lamps
With floating lamps: the shoals rise to the light on moonless nights, and many crews have begun swapping their kerosene lanterns for solar ones.
Q 28The Nile perch was brought into Lake Victoria in the 1950s mainly to do what?
Boost the fish catch
Boost the fish catch was the aim: the lake's small, bony native fish were little valued, and the big predator was expected to turn them into a far more valuable catch.
Q 29Which 2004 documentary suggested that planes flying Lake Victoria's perch fillets to Europe came back carrying weapons?
Darwin's Nightmare
Darwin's Nightmare drew fire from French historian François Garçon, who wrote an article and then a whole book disputing the film's facts.
Q 30How do most of Lake Victoria's cichlid mothers protect their eggs and newly hatched young?
Carrying them in their mouths
Carrying them in their mouths starts at courtship, when the female scoops up her eggs, and she keeps the hatched larvae inside until they can swim freely.
