Attabad – locals taking the situation into their own hands
Several media outlets in Pakistan are reporting that the level of frustration amongst the displaced people at Attabad has reached the point that they have taken the situation into their own hands. The Pamir Times has a pictorial record of what they have chosen to do – a large group have been working on the banks of the channel in an attempt to widen it. There is a full gallery …

Attabad – remarkable stability on the spillway – and some thoughts on what to do next
I will shortly post the latest update on the monitoring site, which shows that the lake level is continuing to rise at about 5 cm per day as inflow exceeds outflow. The spillway continues to show a remarkable level of stability. These two images compare an image from Sunday (left side) with one taken 24 hours later on Monday (right side). Whilst it is tempting to play spot the difference, …
The strange similarity between the Attabad and the landslide in Oliver
Yesterday I posted in both the ongoing situation at Attabad (and I am glad to say that it now seems likely that the reported landslide at Shimshal was a false alarm) and the mud and debris flow at Oliver in Canada. It is now reported that the Oliver slide was caused by the failure of an embankment retaining a small irrigation lake. If that is the case then I assume …

Attabad – a further twist in the tail
Over the weekend the water level in the lake at Attabad has started to rise once again (see the monitoring site), presumably indicating that the warm weather in the Hunza region is increasing the rate of snowmelt, and therefore of inflow to the lake. The continued choke on flow being imposed by the large boulders in the channel is clear. The channel itself continues to evolve slowly through widening (image …

The continued threat posed by landslides at Attabad
Attention continues to be focused upon the state of the spillway at Attabad, and in particular the likely impact of the increase in flow we might see over the next few weeks. Yesterday’s images from Focus showed that slow evolution of the spillway continues, with the lake level reported to have dropped only by a:n inch (2.5 cm): However, we must not lose sight of the potential for other failure …

Attabad spillway video
Thanks to a number of people for drawing my attention to the Hunzaonline video on youtube that shows the spillway in action. The caption indicates that this was collected on the 8th June: Three observations about this video: It shows that the major restriction on flow is still the large boulder at the saddle of the spillway; A second boulder has formed substantive constriction downstream as well, but this is …

Slowing evolution of the spillway at Attabad
Once again I am grateful for Focus Humanitarian Assistance for sending the latest photos of the spillway at Attabad. The rate of change new seems to be slowing as flow is being controlled by the large boulders at the head of the channel. This pair show the downslope side of the channel – the left hand image was taken on 7th June and the right hand image a day later: …

Latest image of the spillway at Attabad
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 …
Attabad – an increasingly difficult hazard to manage
Apologies to all who emailed and left messages over the weekend requesting updates. FWO data collected at 8 am on Saturday suggests that the rate of flow was 124.6 cumecs, whilst the Pamir Times reported yesterday that it was 131.7 cumecs. If so, the discharge time graph looks like this: Thus, the discharge is apparently stabilising. Various media reports from the site itself suggest that downward erosion of the channel …

Attabad: spillway flow update of 08:30 this morning
There is a mass of confusing and contradictory information about the state of flow in the Attabad spillway, but the FWO data appears to be consistent at the moment. The latest data, again via Dr Sadiq, is that flow was 3700 cusecs (105 cumecs) at 08:00 local time this morning. This makes the graph look like this: This suggests that we are still seeing an incremental increase in flow. However, …
