Geographical Overview & Course

Rising from the Gangotri Glacier in the Uttarakhand Himalayas as the Bhagirathi River, the Ganges descends into the northern plains of India. It unites with the Alaknanda at Devprayag to form the Ganges proper, traveling east through one of the most densely populated and agriculturally fertile plains on Earth before merging with the Brahmaputra.
Measurement Discrepancies & Scientific Uncertainty

Official Survey of India measurement records 2,525 km from Gaumukh to the Bay of Bengal.

Ecological & Environmental Significance

Home to the critically endangered Ganges river dolphin (Platanista gangetica), the gharial crocodile, and the Sundarbans mangrove tiger sanctuary.

Economic Importance, Navigation & Human Settlement

Irrigates millions of hectares of rice, wheat, and sugarcane, underpinning the food security of South Asia.
