River Rangpo is a river in the Indian state of Sikkim. A tributary of the Teesta River,[1] it originates from Menmecho Lake and flows through Rongli and Pakyong subdivision villages in East Sikkim towards Rorathang and Rangpo. The river demarcates the border between East Sikkim and Kalimpong district of West Bengal from Rorathang to Rangpo. At the town of Rangpo the river joins river Teesta. River Rangpo is the third largest river of Sikkim after Teesta and Rangeet.
The river runs through most of East Sikkim and a few parts of the Kalimpong District of North Bengal. This tributary flows mainly from east to west with a variable channel pattern including braided, meandering, straight, gorge and blocked lake. Landslides are very common along the river bank as cliff-like bedrocks are significantly exposed along the river valley wall.
During Monsoon season especially from June to September, the volume of water in the river and its tributaries rises heavily due to continuous rainfall in Sikkim.
The important towns along the route of this river are Rangpo, Rorathang, Rongli etc in East Sikkim.
Its confluence with Teesta River is immediately downstream of Rangpo town, the confluence point is known as Indrakil Prayag.
