The Teesta River originates from the Teesta Khangtse Glacier in the eastern Himalayas at an altitude above 5,400 metres. It flows for approximately 414 km total — roughly 305 km through India (Sikkim and West Bengal) and 109 km through Bangladesh — before joining the Jamuna River at Phulchhari Upazila. The Teesta is the largest river in Sikkim and the second largest in West Bengal.
- The basin lies across Sikkim (72.43% of drainage area) and West Bengal (27.57%).
- Total drainage area: approximately 12,540 sq. km across India and Bangladesh.
- In Bangladesh, the river irrigates five northern districts, making it critical for dry-season agriculture.
- The river is fed by Himalayan glaciers and snowmelt, making its flow highly seasonal.
