DOLAHAT TINIALI, Nowboisa (North Lakhimpur), July 9 - Work is in progress to block diversion of the river Singra and to bring it back to its original course at Dolahat Tiniali in Nowboisa.
The Water Resources Department has been involved round the clock to tame the river since flash floods changed the Singra�s course and submerged NH-15 by breaching the Nowboisa-Dolahat PWD (Rural) Road on June 28.
The Water Resources Department of Lakhimpur district has been trying to build a coffer dam about a metre higher than the water level on the diversion portion of Singra for more than a week as the water current is considerably strong.
The unusual nature observed in Singra this time has baffled many local residents. Though the river often overflows during the monsoon season in many areas of Nowboisa, away from the bridge on NH-15, this time the Singra overflowed near NH-15, took a sharp turn to the right and breached the PWD road and inundated a wide residential-cum-agricultural area and submerged NH-15 at Raj Ali.
What has caused concern among the local people is the continuous flow of water in the river despite receding rainfall in the area since the last couple of days.
It was earlier assumed that a blockade in the course of the river Singra in the hills of Arunachal Pradesh due to landslide and its subsequent release caused the flash flood on June 28. But the quantum of river water since the breaching incident has raised many questions.
The memory of breaching of Ranganadi�s right side embankment at Aamtola and left side embankment at Bogoleejan last year due to the dam-induced flood of NEEPCO�s Ranganadi Hydro-Electric Power Plant at Yazali in Arunachal Pradesh is still very fresh among the people in Lakhimpur.
The possibility of diverting water of the Ranganadi to Singra inside Arunachal Pradesh cannot be ruled out by observing the present status of the river at Dolahat Tiniali.
