Subansiri Lower Hydroelectric Project (SLHP), a mega river dam project being built by NHPC at Gerukamukh in the Assam-Arunachal border area of Dhemaji district, has completely failed to withstand natural disasters before it is commissioned. Despite the fact that one of the main goals of the mega project was to control the massive flood and erosion problems caused by the Subansiri River, the largest tributary of the mighty Brahmaputra, the project’s main dam is unable to control the catchment area’s overflown water.

Since Thursday, the overflowing water has been pouring down over the project’s main dam for the third day. The water level of the Subansiri River began to overflow in the catchment area of the SLHP in recent days, owing to heavy rains in the state of Arunachal Pradesh. As a result, water has been pouring over the project’s main dam since Thursday, wreaking havoc in the river’s downstream area.

The guard wall that was built to protect the project’s main dam has reportedly collapsed due to the rapid surge of overflowing water. Until the time of filing this report, the overflowing water of Subansiri was rolling down three metres high over the project’s main dam.
