Etymology
The name of the river is formed of two Sanskrit words ''kar'' (hand) and ''toa'' (water).
Course
The Karatoya, known as Phuljhur rises in the Baikunthapur jungles in the extreme north-west of Jalpaiguri district (West Bengal, India) and forms for some distance the boundary between Dinajpur and Rangpur districts. It, then, meanders through Rangpur and Bogura. In the south of Bogura district, it receives the Halhalia and the united stream is then known as Phuljhur. It leaves Bogura at Chanda kona and flowing in a southerly direction past Raiganj and Shujapur is joined by the
Ichhamati at Nalka. The Phuljhur then flows south past the important village of Ullapara, a few miles below which it joins the
Hurasagar at Narnia after a course of about in this district. After this junction, it takes the name of Hurasagar and passing close by Shazadpur and Hera joins the Jamuna near Bera.

The map (''right'') shows the main rivers in North Bengal and adjoining areas. Not shown are numerous tributaries and distributaries, which connect the main rivers, and allow the main rivers to change course. Therefore, the river-system pattern undergoes continuous changes. Such changes have not been reflected in the map. Moreover, many of the rivers have local names for sections of the course, adding to the complexity of the river system.
The Karatoya is made up of four parts and connects adjoining rivers.

It is shown in Van Den Brouk's map of Bengal (C, 1660) as flowing into the Ganges and in fact. before the destructive floods of 1787 it brought down to the Atrai and to the Ganges a great volume of Teesta water. Since the main stream of the Teesta was diverted to the east in 1787, the Karatoya and the Phuljhur have gradually silted up. and they are at the present day rivers of minor importance. One channel, which joins the Baral, east of Pabna. is still called indifferently the Buri Teesta or old Teesta and the Karto or Karatoya. Traces of an old channel, for which the name of the Karatoya is claimed, are also pointed out in the Chatmohar thana, where it appears to have been obliterated by the Baral.
