The Government has decided to open the Dam periodicly since it can no longer bear the water volume from the rivers flows into it. The sediment has raised up to 100 million m3 of 120 million m3 dam's capacity.
People in the lower course protest this policy, because it means they have to live in flood longer. But if it is not done, a bigger disaster might happen.
The dam might be broken down and let the water flow down uncontrolled.
What happened to mother nature?
