The Jaldhaka River (Pron:/ˌdʒælˈdɑːkə/) (Bengali: জলঢাকা নদী), also known as Dichu River in earlier times,[1] is a trans-boundary river flowing through India, Bhutan and Bangladesh with a length of 192 kilometres that originates from the Kupup or Bitang Lake of Pangolakha Wildlife Sanctuary in East Sikkim in the Eastern Himalayas and flows in East Sikkim India than goes to Bhutan at Samtse District comes back to India at Bindu, Kalimpong district than further flows through Kalimpong, Jalpaiguri and Cooch Behar districts of West Bengal, India. Then the river enters Bangladesh through the Lalmonirhat District of Rangpur Division. It is known as Dharla River in Bangladesh until the Dharla debouches into the Brahmaputra River near the Kurigram District. Due to the river's wandering over several international borders, only a small length of the river lies within Bangladesh and Bhutan. In some places, this river is also known as Mansai river and Singhimari river.[2]
Geography[edit]
The Jaldhaka River gains volume by the conjunction of three streams at Bindu, the end point of the Jaldhaka Police Station at Kalimpong district in West Bengal. The three streams are known as Bindu Khola, Dudh Pokhri and Jaldhaka that originates from the Kupup Lake, a small glacial lake in Sikkim. The combined streams meet at Bindu to increase the volume of Jaldhaka River, thus forming a riverine boundary with India and Bhutan in the left bank. The main tributaries that join the river in its right bank are the Murti, the Jholung khola, the Naksal Khola, the Sutunga and the Jarda in the lower reach. The Diana, Rehti-Duduya and Mujnai are the main left bank tributaries.
The river flows through the three North Bengal districts of Kalimpong, Jalpaiguri and Cooch Bihar. The entire watershed is the most fertile agricultural zone along with the Teesta Basin. The upper course is famous for crops like ginger, medicinal herbs and fruits like oranges and pomegranate. The middle course comprising Jalpaiguri district is entirely tea and corn dominated and the lower course is dominated by rice, jute and tobacco. The inter-river formed lands are cultivated with crops like bamboo and mat sticks. In the lower basin, the inter-river lands are cultivated with banana.
The river enters Bangladesh at Ghoksadanga district to meet the Brahmaputra or the Jamuna as it is known there.
