The wonderful people at Focus have provided an image of the state of the spillway at Attabad that is very instructive. This was taken today:
The current state of play is I think as follows. Flow appears to be constrained by two blockages but, as a commenter has noted, one is a rock spur out of the channel. The blockage appears to have formed a small waterfall / rapid. Downstream of the blockage the channel has widened dramatically - and indeed a section of the track has now been lost.
To me this suggests that the crisis may be far from being over. In particular, the loss of this barrier could cause a rapid increase in flow rate that could be highly erosive. It is however important to stress that interpreting the state of play from photos is difficult.
