Decision to Blast at Attabad

Dave Petley reports that there has been a decision to blast out some of the rocks in the channel at Attabad, but there is no information about which boulders are to be blasted. The large "boulder" at the top of the spillway is shown at the right. There has been considerable erosion around it in the past few days.  For those who raft in the Grand Canyon, the image conjures up nightmares of the bad waves of Lava Falls in the Grand Canyon!

There is, however, a second big boulder downstream and it's not clear to me that blasting the first one will do anything but move the choke point downstream to this boulder.
