Jalpaiguri, Jan. 16: The Centre has released nearly Rs 13 crore for the construction of spurs on the Teesta a few kilometres from here, where the river changed its course last monsoon and threatened to flood Jalpaiguri town. River expert Kalyan Rudra has termed the measure temporary and suggested that dredging could be an option. Subdivisional engineer of the irrigation department Keshab Roy said the Teesta had broken its bank at Gourikone last year and veered to the right, 5km off course towards Rangdhamalirhat, a densely populated area.
