THE situation in Hunza is dire to say the least. Indeed, the lake, which has already taken a heavy toll on life and infrastructure of the region, even inundating a large chunk of the Karakorum Highway, now threatens to devour thousands of lives and hundreds of villages down the valley. But we are being told by Army engineers and the National Disaster Management Authority that the rock debris that is acting as a natural embankment would not break and water would just overflow it and go down through the spillway that is currently under construction. Only a breach may occur, they have warned nonetheless, which is a tacit acceptance of the possibility of the barrier’s breakdown.
Their claim that the dam would not break is absurd because the debris that now constitutes this barrier largely consists of shale rocks and pebbles. Shale rocks are weak rocks and a water flow easily carries them away. The sheer pressure of water gushing from the glaciers in a downhill direction is like that of a bulldozer and it is only nonsensical to assume that this embankment would be strong enough to bear that.
The engineers are also saying that the only option available is to rely on the spillway, which would slowly transport the water downstream without causing a major catastrophe. Unfortunately, this is too little too late. Given the huge size of the reservoir, which continues to rise about 2 feet per day owing to melting glaciers and rainwater, the water would be a little too much for the spillway to take. Experts have warned that the wave resulting from breakdown of the bank could be as high as 200 feet. If life and property is to be saved, human settlements and areas coming in the way of the stream should be evacuated. Secondly, in order to limit the damage, it should be ensured that Tarbela Dam is able to absorb the floodwater.
Again this Hunza lake fiasco shows the laidback attitude of our rulers. Much before January, when the landslide occurred, Geographical Survey of Pakistan had warned the government to blow up the rocks through dynamite so as to prevent the formation of the lake. But nobody paid heed because no one seems to care.
Please make dua for our brothers and sisters there. May Allah(swt) protect them from any harm.....
