Rescue agencies are using underwater sonar system to locate bodies in muddy waters downstream of Rishiganga dam site, especially in the waters of Srinagar dam, said officials. The rescuers have also been drilling a hole in the Tapovan Dam tunnel vertically downwards since morning so that a camera can be installed to know the status of another underground tunnel, nearly 11 metres below the existing one, said officials.

Chamoli Police have also issued an alert of rising water level in Alaknanda and appealed to people to remain vigilant, especially those living near its banks.

A senior official, wishing not to be named, said, “From the tunnel we are approaching now, we have to reach 180 metres, then take right, where there is a pocket, where the NTPC officials are expecting trapped workers. At around 74 metre in the approaching tunnel, there is another tunnel around 11 metres below. We are trying to put a camera into that tunnel… But it is taking time”, said a senior officer involved in the rescue operation, wishing not to be named.

SDRF commandant Navneet Bhullar said 25 to 35 workers are still trapped inside the Tapovan dam tunnel, where rescue operation is underway. He said the muck has been removed from over 100-metre length of the tunnel so far.

He said downstream, SDRF personnel are using underwater sonar systems on a boat to track bodies in muddy waters in the vast waters of Srinagar Dam reservoir. “SDRF has two drones which are being used for geo-mapping of the Tapovan dam tunnel. NDRF has also brought some high endurance drones which are also being used. So we are using all possible means- drones, dog squad, binoculars in the search operation,” he said.
