Teesta River

description Teesta River Overview

The Teesta is a Himalayan river that rises in the Indian state of Sikkim and flows through West Bengal before entering Bangladesh. Its course is approximately 315 kilometres long, descending through steep mountain valleys and then crossing the plains before joining the Brahmaputra river system. The river supplies irrigation and hydroelectric projects, while its seasonal flow and allocation are important issues for communities in both India and Bangladesh.

help Teesta River FAQ

Where does the Teesta River flow?

The Teesta rises in Sikkim, flows through West Bengal, and then enters Bangladesh. In Bangladesh it continues toward the Jamuna, the local name for the Brahmaputra's main channel.

Why does the Teesta change from a mountain river to a plain river?

Its upper course descends through steep Himalayan valleys in Sikkim and northern West Bengal. Farther south, the river spreads across the flatter alluvial plains of West Bengal and Bangladesh. [Teesta overview](https://en.wikipedia.org/wiki/Teesta_River)

Which major river does the Teesta join?

After crossing into Bangladesh, the Teesta ultimately joins the Jamuna, the Bangladeshi name for the Brahmaputra. The confluence is associated with the northern Bangladesh districts around Sundarganj and Chilmari.

Why is the Teesta important in India-Bangladesh relations?

The river is transboundary, so its seasonal water supply affects irrigation, floods, and river communities in both countries. Bangladesh's Teesta Barrage is one visible part of the river's farming and water-management system.
