Hooghly River The Hooghly River (Hugli; Anglicized alternatively spelled Hoogli or Hugli) or the Bhāgirathi-Hooghly, traditionally called 'Ganga', is an approximately 260-kilometre-long (160 mi) distributary of the Ganges River in West Bengal, India.[1] The Ganges splits into the Padma and the Hooghly near Giria, Murshidabad. The Padma flows eastward into Bangladesh, whereas the Hooghly flows south through West Bengal. The river flows through the Rarh region, the lower deltaic districts of West Bengal, and eventually into the Bay of Bengal. The upper riparian zone of the river is called Bhagirathi while the lower riparian zone is called Hooghly. Calcutta and Hugli-Chinsura, the headquarter of Hooghly (district), is located on the banks of this river.[2]
