The way this (completely predictable and preventable) man-made disaster is being covered is both ridiculous and infuriating.
Every news outlet is dutifully reporting that a “cloudburst” over Lhonak Lake led to a “flash flood” which then (somehow?!) took out a 25,000 crore ($3 billion) dam in a brief 10 minutes.
What happened in Sikkim is emphatically NOT a simple little cloudburst nor a simple flash flood.
What is really was: A huge glacial-moraine dammed lake that first appeared in 1962 and that has massively grown in size the past few years - all due to global warming - finally breached the moraine. About 2/3 of the water of the lake poured through the breach in a short while.
Pro tip: That is not a “flash flood”. That is a glacial lake outburst flood - which, given the size of the lake, is several orders of magnitude larger than a simple flash flood caused by a thunderstorm.
This massive bolus of water then struck the massive, $3 billion Teesta 3 dam at Chungthang, 60 meters high and just recently completed, washing it away in 10 minutes flat and causing an even LARGER flood due to the dam breech and loss of the entire, massive reservoir. This released an additional 5.08 million cubic meters of water to wreak havoc downstream.
So a few points:
None of this is a “cloudburst” or a “flash flood”
Rather it is a completely foreseeable and preventable man-made disaster
The danger of the bursting of the Lhonak Lake moraine has been well known for quite some time
That danger must have been well known to designers of the Teesta 3 dam, yet they clearly made the decision to do nothing about it
The creation and growth of Lhonak Lake starting in the 1960s is due to increased glacial melting clearly attributable to global warming
The recent growth of the lake is, likewise, clearly attributable to increased global warming
The bursting of the glacial moraine at the end of the hottest summer in recorded history can scarcely be coincidental. The lake was visibly growing in size just in the very recent past.
Again, this was a well known danger in the region and the decision to do nothing to ameliorate the danger - while actually moving ahead with projects downstream that only multiply the risk - can only be attributed to some combination of negligence and incompetence.
Heavy rains in the region only added to the problem - but from heavy rain alone it is very hard to imagine the bursting of the Teesta 3 dam, which led to the major flooding, damage, and death.
In short: Don’t blame the cloudburst. This was an entirely human created, human caused, disaster that could have been averted, or at least greatly minimized, with by relatively simple means and a little bit of foresight.
So why is every mainstream news outlet in India erroneously referring to the disaster as a “flash flood” caused by a “cloudburst”? It took me literally 2 minutes of googling to find out the actual cause.
