Early History

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 Bogra. In the south of Bogra district, it receives the Halhalia and the united stream is then known as Phuljhur. It leaves Bogra at Chanda kona and flowing in a southerly direction past Raiganj and Shujapur is, as already mentioned, joined by lchhamati 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 40 miles 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 Karatoya is mentioned in the Puranas and had a high repute for sanctity. It was the eastern boundary of the old kingdom of Paundravardhana, the country of the Paundras which it separated from Kamrupa. 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 dirverted 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, 30 miles 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.

Etymology

The name of the river is formed of two Bengali words kar (hand) and toa (water), signifying, in Hindu mythology, that the river was formed by the water which was poured on the hands of Shiva
Shiva
Shiva is a major Hindu deity, and is the destroyer god or transformer among the Trimurti, the Hindu Trinity of the primary aspects of the divine. God Shiva is a yogi who has notice of everything that happens in the world and is the main aspect of life. Yet one with great power lives a life of a...

Changes in the course of rivers

Great changes have taken place in the course of some of the rivers in Bengal

 and the adjoining areas, during the period since 1500 AD. Although positive evidence is lacking, similar changes can be assumed in the remoter past. The Karatoya is one of the rivers that has changed over the years.

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.

Tectonic disturbances have broken up the Karatoya into four distinct parts. The northern part, called the Dinajpur-Karatoya, is the main source of the Atrai
Atrai River

 in Jalpaiguri district, but also receives water from underground streams. In Khansama upazila its name changes to Atrai. In a second section, the Dinajpur-Karatoya was connected with the Rangpur-Karatoya north of Khansama, but very little water now passes down that channel. The upper part of Rangpur-Karatoya originates in the Jalpaiguri district and is known as the Deonai-Jamuneshwari up to Gobindaganj upazila. In a third section, the Jamuneshwari-Karatoya flows south-southeast to Gobindaganj upazila

. The portion of the former river passing through Shibganj upazila is dry most of the year. It effectively separates the Rangpur-Karatoya from the Bogra-Karatoya, which flows south past Bogra town till it joins the Bangali to make Phuljhor river, which falls into the Hoorasagar. The fourth part, the Pabna-Karatoya, is a moribund river bed near Handial. Various other channels are also pointed out as parts of the Old Karatoya.

In the Siyar-al-Mutakhkhirin it is recorded that the Karatoya was three times the size of the Ganges when Bakhtiyar Khilji invaded the northern parts of Bengal in 1115. In Ven den Brouck's map of Bengal, prepared in 1660, the Karatoya is shown as a large channel. Rennel made a survey between 1764 and 1777 and his maps are one of the earliest authentic maps of Bengal in existence. In these maps Teesta is shown as flowing through North Bengal in several branches – Punarbhaba, Atrai, Karatoya etc. All these streams combined lower down with the Mahananda, now the westernmost river in North Bengal, and taking the name of Hoorsagar finally discharged into the Ganges at Jafarganj, near modern Goalundo. The Hoorsagar river is still in existence being the combined outfall of the Baral
