Using only reliable reports in the media (mostly information from the Pamir Times) and those from NDMA, the following graph shows the reported flow through the spillway at Attabad. There is a huge caveat here regarding the reliability of the reports. However, the most recent figure is the NDMA reported value. Times are local to Pakistan (UT +5 hours)
It is clear that flow is now increasing quite rapidly. However, do not be panicked by this – it is as we would expect and does not indicate anything in particular at this stage. Meanwhile of course the water level in the lake is still rising at about 2.5 cm per hour, which will be increasing the impact on the upstream communities. We must not forget them is this crisis.

Upstream communities: "We must not forget them in this crisis." yes Dave. Thank you for reminding us. Keep up the great posts.
