  • Lake formation at Rishi Ganga river poses bigger threat than Sunday flood

    Express News Service
    TAPOVAN: A lake that was formed in the absence of flow in the Rishi Ganga river now poses a greater risk of disaster, if it bursts, than that of the Sunday flashfloods, rue experts. 

    However, the scientists familiar with the landscape said that the water from the lake started draining on Friday which minimizes the chances of bursting of the water body.

    YP Sundariyal, head of the department of geology department of Hemvanti Nandan Bahuguna Garhwal University said, “The lake is around 250-300 meters long, 80-100 meters wide and of about 25-30 meters height. The lake has a big volume of water and hypothetically speaking if it bursts, it can cause more damage than earlier. Big relief is that the water is slowly draining from the lake so it will not burst. The authorities should try to drain the lake without trying to burst it using experts.”

    Sundariyal, a geologist by profession told The New Indian Express that a similar kind of lake but of a bigger size was formed in 1998 in Madkakini river in Madmeshwar valley which had drained without causing any damage.

    “There was panic but the lake drained and the danger was averted. We hope same thing will happen to this lake too as it is already draining,” added.

    Uttarakhand Chief Minister Trivendra Singh Rawat confirming the lake formation said, “We know about the lake and we are keeping an eye on it through our satellites. We need not panic but stay alert. Our team of scientists have been dispatched for the lake. We are trying to get them to the spot of the lake formation to assess the ground situation.”

    A team of Indo-Tibetan Border Police, scientists from DRDO, Uttarakhand Space Application Centre (USAC) conducted and aerial survey of the lake but were not able to reach the lake through ground.

    D P Dobhal, glaciologist who worked at Dehradun’s Wadia Institute of Himalayan Geology said, “I saw the pictures. The lake formation is dangerous but now that the water is draining slowly the threat has minimized but not diminished.

    The rubble is huge and holding the water while drainage is on but if the lose material is pushed away by water it will be a big threat.”

    Commenting if the forecast of rainfall up to 1 cm and snowfall up to 10 cm over the northern parts of the disaster-hit Uttarakhand early next week by India Meteorological Department (IMD) will be a factor in amplifying the tgreat, Dobhal said, “The threat will depend on the magnitude of snowfall and if its 10cm then it will add in 1cm of water which won’t be much threat but again we need to stay alert as situation is developing and volatile.” 

    Incidentally, on Thursday a video featuring a geologist from the same varsity surfaced claiming lake formation in higher reaches in Rishi Ganga river.

    Geologist Naresh Rana of the the Hemvanti Nandan Bahuguna Garhwal University, Srinagar, in the video, explained that “the flood created a temporary damming which blocked Rishi Ganga from forming the lake.”

    A slight breach to this temporary situation can unleash havoc to those downstream, he added.

    “This can hamper the rescue efforts and it can hurt people who are involved in rescue operations. I am going to inform the administration so that they can conduct and aerial survey so that the correct size of the lake is determined,” said Rana.

    Geologist Naresh Rana of the the Hemvanti Nandan Bahuguna Garhwal University, who released a video from the vicinity of the lake said, “What I understood from a bit of distance that the water has been accumulating for some days now. There are chances that the water will be drained with time but still it poses grave threat. There will be more clarity only after ground assessment which is being done.”

  • Chamoli disaster: Sirens, confusion ensue at rescue spot after water levels of Rishi Ganga rise

    Express News Service
    TAPOVAN: At the spot of the Tapovan tunnel rescue mission located near the Dhauli Ganga, more than 50 journalists and top officials were caught off guard by a warning call at around 2:10 pm. 

    “They said water levels are rising. Bhago Bhago yahan se!,” screamed a man amidst the gathering.

    “I saw muddy water flowing rapidly. That meant there was a huge inflow from the higher mountains. I was scared for myself and for everyone. I called up and told my friend in Tapovan. I did not want what happened on Sunday repeat,” said Sohan Rana from Raini village who alerted people in Tapovan.

    Mohan Singh, another resident of the village where the Chipko Movement started in 1973, said, “We saw a lot of water flow in Rishi Ganga. This was not the case yesterday. The dry patch was now overflowing with muddy water. This cannot be without water flowing in from the upper reaches like it did on Sunday flash floods. We cannot take any chances right now. We started making calls to everyone we knew was anywhere near the river.”

    The people fled the spot while sirens, whistles and shouts filled the area struck by one the worst flashfloods of Uttarakhand.

    The rescue operations were suspended temporarily only to resume after two hours at around 4 pm with excavators clearing the tunnel and the multi-agency rescue mission starting work.

    Rescue personnel, workers and engineers trying to install a trolly bridge on river Dhauli Ganga started running towards high slopes.

    “I got a call that the water was rising in Rishi Ganga at an alarming rate. I disconnected the call and shouted ‘Bhago Bhago’. I could not think of anything else,” says Rajesh Singh of Joshimath who was at the rescue spot with a friend.

    Ravinath Raman, commissioner of Garhwal division who was one of the officials conducting the press conference which got disrupted said, “I immediately ordered everyone to leave the spot. We cannot take any chance,” said Raman.

    The officials who were present in the press conference included commissioner of Garhwal division, district magistrate of Chamoli district Swati Bhadauria, the commissioner, Yashwant Singh Chauhan the superintendent of police, Neeru Garg the deputy inspector general, Colonel DS Negi from the Indian Army, Ujjawal Bhattacharya, RP Ahirwar from NTPC Limited and atleast 30 men from State Disaster Response Force and various other departments.

    Chauhan, who was the only one refusing to budge even after the siren went off shouted on top of his voice, “Pehle andar (inside the tunnel) walon ko bahar nikalo. Sab beh jaenge. (Get the men working in the tunnel first else they will be washed away.)”

    When asked why he did not leave, he said, “Did you see the Army men leaving or any men from any other forces. We are trained to try to save others first. We know how to act instead of panic. Of course I was careful and confident that I can run and climb the high ground fast enough.”

    Meanwhile, the news of a formation of a lake from the blockage of Rishi Ganga river trickled later in the day.

    This was later confirmed by the officials.
