Geography of Jaldhaka River
Globally, Jaldhaka River can be pinpointed at coordinates 27.0297 degrees north and 88.8747 degrees east.
Course of Jaldhaka River
The course of the River Jaldhaka has a length of about 192 kilometers. This river originates from the Kupup (also known as Bitang Lake
), a small glacial lake in southeastern Sikkim
in the eastern Himalayas
. It is formed by the union of three streams namely, Bindu
Khola, Dudh Pokhri and Jaldhaka. The location of the confluence is Bindu, which is a small hamlet or the last village
on the Indian side bordering Bhutan in the Darjeeling district
of West Bengal. A riverine boundary is thus formed by this river with India and Bhutan on the left bank. It journeys through Bhutan and three districts of West Bengal namely, Darjeeling, Jalpaiguri
and Cooch Behar
. In the district of Cooch Behar, the river takes the name Singimari. The river enters Bangladesh through the Lalmonirhat District. It then amalgamates with the Dharla River and is therefore known as the Dharla. The Dharla heads towards the Brahmaputra River
near the Kurigram District. The river traverses only for a small length in Bangladesh. The river thus can be said to journey over several international borders.
