The expert’s discussion on the various websites seems restricted to the boulders visible on the surface and their expected movement, owing the flow of water and erosion thereof as seen in this video, in the newly formed shallow channel.
But the entire spillway is filled with hundreds of such big boulders, packed in between by the smaller boulders and the debris to have formed a strong long barrier.
Option of controlled explosions to ease the spillway is also being evaluated by DMNA.
All the efforts applied may reduce the lake level to an extent. This may give some relief to the upstream population but looks like this lake is now there to stay for good.
