Strange goings on at Attabad

The NDMA daily report for today (22nd July) reports a dramatic decrease in lake level – 19 inches (48 cm) in the last 24 hours.  This is by far the largest fall recorded to date, producing a lake level the looks like this: This is quite surprising.  Assuming that the surface area of the lake is 1202 hectares (in fact it is probably a little larger in reality), this implies …
