The Karatoya, known as the
Fuleswari which source in the ᤘᤠᤖᤰ ताल of
Himalayas in
Nepal, 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 the Phuljhur. It leaves Bogura at the 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 the Hurasagar and passing close by Shazadpur and Hera joins the
Jamuna near Bera.
Course changes The Karatoya is one of the rivers that has changed over the years. Previous rivers that the Karatoya connected to included the
Teesta and
Kosi. 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. ==History==
