GK Quiz: Which River In India Is Known As The Red River?

India is often called the land of rivers, with hundreds of waterways supporting livelihoods, agriculture, and centuries-old cultures. While many rivers are celebrated for their length or volume, one stands out for a different reason: its colour. During the monsoon, this river transforms into a striking reddish-brown, earning it the nickname India’s ‘Red River’.

Do you know which river we’re talking about? It’s the Brahmaputra. Famous for its vast width and mighty flow, the river turns a striking reddish-brown during the monsoon as it carries heavy silt and soil, making it a unique and iconic symbol of Northeast India.

Origin And Course Of The Brahmaputra

The Brahmaputra originates near Lake Mansarovar in Tibet, emerging from the Chemayungdung Glacier, where it is known as the Yarlung

Tsangpo. It flows eastward across Tibet before making a dramatic bend and entering India through Arunachal Pradesh, where it is called the Siang.

The river then travels through the fertile plains of Assam as the Brahmaputra, before entering Bangladesh as the Jamuna. There, it merges with the Ganges and eventually empties into the Bay of Bengal.

Why Does The Brahmaputra Turn Red?

The reddish colour of the Brahmaputra is mainly due to the iron-rich soil along its banks, particularly in Assam and surrounding regions.

During the monsoon, intense rainfall washes large amounts of this soil into the river, giving the water its distinctive reddish-brown appearance. This natural phenomenon is why the Brahmaputra is popularly known as India’s Red River.
