Analyzing Statements about the Teesta River

Let's carefully examine each statement provided regarding the Teesta river to determine its accuracy.

Statement 1: The source of river Teesta is the same as that of Brahmaputra but it flows through Sikkim.

• The Teesta river originates from the Pahunri (or Tso Lhamo) lake in the Sikkim Himalayas.
• The Brahmaputra river originates from the Chemayungdung glacier near Kailash Mansarovar in Tibet.
• Clearly, the sources of the Teesta river and the Brahmaputra river are different.
• The Teesta river is indeed a major river flowing through the state of Sikkim in India.

Based on the different origins, the first part of the statement is incorrect. Therefore, Statement 1 is incorrect.

Statement 2: River Rangeet originates in Sikkim and it is a tributary of river Teesta.

• The Rangeet river is a major river in Sikkim. It originates in the Singalila range in West Sikkim.
• The Rangeet river is the largest tributary of the Teesta river. They merge at Melli on the border between Sikkim and West Bengal.

Both parts of Statement 2 are correct. The Rangeet river originates in Sikkim and is a significant tributary of the Teesta river. Therefore, Statement 2 is correct.

Statement 3: River Teesta falls into Bay of Bengal at the border of India and Bangladesh.

• The Teesta river flows through West Bengal in India and then enters Bangladesh.
• In Bangladesh, the Teesta river joins the Brahmaputra river, which is known as the Jamuna river there.
• The Jamuna river (Brahmaputra) then joins the Padma river (Ganga) further downstream.
• Finally, the combined flow of the Padma and Jamuna rivers, along with the Meghna, falls into the Bay of Bengal.
• The Teesta river itself does not directly flow into the Bay of Bengal. It merges with the Brahmaputra (Jamuna) river well within Bangladesh, not directly at the India-Bangladesh border where it enters Bangladesh.

Since the Teesta river is a tributary of the Brahmaputra (Jamuna) and doesn't directly enter the Bay of Bengal, Statement 3 is incorrect.
