Lachung River

Course

The river has its source in a lake, deep in the Himalayas near the Indo-China border. The ragged reaches of the mountain make the place almost inaccessible. From here, the river flows down in a south-westerly direction and joins with another unknown river at a place just above Lachung village. The tributary river is also a slender one with little water in the winter. The river continues its course downwards through the Lachung valley till it meets River Lachen near Chungthang. After the confluence, it takes the name of River Teesta and flows further down. It becomes wider while travelling to Singhik and drops from altitude of 1,550 to 750 metres (5,090 to 2,460 ft). At Singhik another tributary river joins it, called the Talung Chug. After this point the river flows to Dikchu through a deep ravine and drops to a height of 550 metres (1,800 ft). Then it cambers and reaches Singtam, which is at a height of 200 metres (660 ft). After Rangpo, the Teesta widens and meets the River Rangeet at Melli Bazaar.
