60 free Ganges trivia questions with answers — geography quiz, new questions added Aug 2026.
The Ganges is a river, a goddess and the spine of northern India all at once, and this quiz treats it as all three. It starts in the ice at Gomukh and follows the water down through Devprayag, Rishikesh and Haridwar to the great confluence with the Yamuna, then on past Varanasi and Patna into the delta shared with Bangladesh, where the river changes its name and joins the Brahmaputra before reaching the Bay of Bengal. Along the way you will meet the mythology (why the river is caught in Shiva's hair, which king's penance brought her down, whose mother she is in the Mahabharata), the wildlife (a blind river dolphin, a pot-nosed crocodilian, a shark that swims upriver, tigers in the mangroves), and the engineering and politics: the Ganges Canal of 1854, the Farakka Barrage, the treaty with Bangladesh, and the long, expensive attempts to clean up the sewage of Varanasi and the tanneries of Kanpur. Easy questions suit anyone who has looked at a map of India; the expert tier asks about Victorian canal engineers and comic-book mascots. Every answer was checked against Wikipedia's articles on the river, its cities, tributaries and wildlife, and the supporting sentence is attached to each question.

Bay of Bengal
It arrives there as part of the vast Ganges Delta, the largest river delta on Earth.

Q 06Which headstream is the source of the Ganges in Hindu mythology, though the Alaknanda is longer?
Bhagirathi
Hindus consider it the true source; the Alaknanda merely wins on length.

Gangotri
The glacier is about 30 km long and holds more than 27 cubic kilometres of ice.

Saraswati
The Ganges is described as flowing white and the Yamuna dark blue or green where they meet.
Q 12At their confluence, the Yamuna actually carries more water than the Ganges. Roughly what share of the combined flow does it contribute?
58.5%
The Yamuna is 1,444 km long and averages roughly 2,948 m³/s at the junction.
Q 13Which river, known as the Karnali in Nepal, is the largest tributary of the Ganges by discharge?
Ghaghara
In its lower Indian reaches through Awadh it is also called the Sarayu.

Around 274 million people live on the delta despite floods and cyclones.
Q 23Which animal has the Government of India declared its National Aquatic Animal?
Ganges river dolphin
It is nearly blind and hunts by echolocation in the muddy water; a 2021-23 survey counted about 6,300.
Including the Ganges' own species, how many kinds of dolphin in the world live only in fresh water?
Q 14What was the main purpose of India's Farakka Barrage diverting Ganges water?
Flushing silt out of Kolkata's harbour
The diverted flow proved inadequate for the job, and the barrage remains a source of friction with Bangladesh.

1975
Construction had begun in 1962; the barrage is roughly 2.3 km long with 109 gates.
Q 16In which year was the 30-year Ganges water-sharing treaty at Farakka signed with Bangladesh?
1996
Within a year the flow at Farakka fell far below the historic average, making the guaranteed shares impossible to deliver.

Hooghly
Most of its water now arrives through the man-made Farakka feeder canal rather than its natural offtake at Giria.

Almost nobody uses the new name; it is still the Howrah Bridge to the 150,000 pedestrians who cross it daily.
Q 19What is unusual about how Kolkata's Howrah Bridge, opened in 1943, was put together?
It was riveted, with no nuts and bolts
It is described as the busiest cantilever bridge in the world.
Q 20The Ganges Delta contains the world's largest mangrove forest. What is it called?

Q 25The gharial, the fish-eating crocodilian of the Ganges, takes its name from the Hindustani word for what?
