ISLAMABAD Despite three-month efforts, authorities seemed helpless on Tuesday in tackling the looming danger that has emerged from a monster lake formed after a landslide in Hunza Valley on January 4. Well-placed sources informed TheNation that 15 kilometres long and 60 metres deep lake with addition of 2,500 cusecs meters water daily had gone out of control and was about to burst and could wreak havoc all the way down to Tarbela Dam. The sources informed that local authorities had already directed the residents of Attabad town and its adjacent areas to move quickly to safer places, adding an elaborate relief and rescue plan had been evolved to meet the eventuality. Hunza Lake has reached alarming proportion and shaken the government, sources informed. Since the landslide, the Hunza Lake had not only led to closure of KKH but also claimed lives of 20 people. Environmentalists and civil society have demanded of the Government to seek technical assistance from neighbouring China to reduce threat and mitigate sufferings of the people. Meanwhile, Chief of Army Staff (COAS), General Ashfaq Parvez Kayani, Tuesday visited the site of landslide that blocked Hunza River near Attabad. He was briefed about the progress of work on spillways, being undertaken by Frontier Works Organisation (FWO). The COAS appreciated the efforts being made by FWO for safe restoration of Hunza River. He also interacted with the people of affected area. Earlier on his arrival, Lieutenant General Shahid Niaz, Engineer-in-Chief and Lieutenant General Tahir Mehmood, Corps Commander Rawalpindi, received the COAS in the area. Army Engineers and FWO have been successful in constructing 415 metres long, 40 metres wide and 20 metres deep spillway cut as an immediate remedial measures, but unfortunately there has been no let-up in plugging the breaches. FWO, which is still working with full vigour, has reduced the danger of damages by 56 percent. However, environmentalist lobbies insist that in case the lake bursts, it would throw up a large flood wave that could travel downstream as far as Tarbela Dam, adding water level is constantly rising by two feet daily as Hunza river feeding the lake.
