The 13.2 MW Rishiganga hydropower project near Jashimath was completely washed away; the 520 MW NTPC hydro project on the Dhauliganga river near Raini was partially damaged and at least five bridges were impacted by the surge of water that was unleashed, cutting access to a number of villages in the area.
The State Emergency Operation Centre said, of the missing persons, 148 were in the NTPC hydropower site whereas 22 were at the Vishnugad project. Most of them are believed to be workers involved in the hydropower projects.
“The maximum water level at the Tapovan barrage is 1,803 metres, but as per initial reports, the water level crossed 1808 metres, causing the breakage,” said Piyoosh Rautela, executive director of the state’s disaster mitigation and management centre (DMMC).
The water level of the Dhauliganga river at Joshimath breached all records, Central Water Commission (CWC) officials said. “At 11am, the water level recorded at Joshimath was 1,388 metres,” Saumitra Haldar, chairman, Central Water Commission told agencies. During the 2013 Uttarakhand flash floods, the highest flood level at Joshimath was 1,385.54 metres, he added.
Chief minister Trivendra Rawat, who conducted an aerial survey and went to areas near the disaster site, announced Rs 4 lakh relief to the next of kin of those killed. PM Modi also announced an ex-gratia of Rs 2 lakh for the families of the deceased. Later in Dehradun, Rawat said a team of 100 Armypersonnel, including those from the engineering task force, and 250 personnel from ITBP’s 1st battalion are engaged in rescue operations.
Officials monitoring the situation said that water flow in the Alaknanda river gradually stabilised ahead of Nandprayag in Chamoli district though a high alert has been issued and people living along the Alaknanda and Ganga river banks on all the districts — from Chamoli to Haridwar — have been asked to evacuate.
Earlier, as a precautionary measure, flow of the Bhagirathi river was stopped and reservoirs of GVK dam in Srinagar and Veer Bhadra dam in Rishikesh were emptied in order to manage flow of the surging Alaknanda.
