High siltation changes river’s course at Mantam Silt to be excavated to the left bank


Mangan, 02 Nov:

Area MLA Sonam Gyatso Lepcha, along with District Collector, North, Karma R Bonpo, Sub Divisional Magistrate, Dzongu, Tshering Dorjee Bhutia, and officials from Roads & Bridges Department inspected Mantam Lake in North Sikkim on 01 Nov in a bid to find measures to commence vehicular movement to the cut-off areas of Tingvong, Lingzya and several other villages beyond the landslide-dammed lake here in Dzongu.

Due to high siltation, the course of Rongyong Chu has diverted towards the right bank, throwing the alignment of the sliding bridge constructed across the lake last year off kilter. Technically, there is no lake left at Mantam anymore with the entire stretch behind the landslide covered by silt and the river now flowing through a channel it has carved out along the right bank.

Engineers from the Road & Bridges Department have suggested excavating some silt on the left bank making the river flow so that the sliding bridge can be realigned at its original place and the vehicles provided access to the cut-off areas.

The DC North informed that once vehicles start plying, stock of essential commodities for six months will be stored in Tingvong like last year so that the public do not face any problems.

The area MLA directed the concerned department and the district administration to start the work at the earliest so that people did not face any problems in connectivity.
