Attabad – draining operations

Posted by Dave Petley

Over the last week there has been a temporary dam in place blocking the spillway at Attabad to allow the Frontier Works Organisation to undertake excavations on the spillway.  It is unclear as to the intention of these operations – i.e. whether these are to deepen the spillway, to widen it, and/or to reinforce it.  However, the Pamir Times reports that the temporary dam was removed today and that the water level is now reducing at a rate of about 7 inches (18 cm) per hour.  Flow through the spillway is reported to be 22,000 cubic feet per second – i.e. about 600 cubic metres per second.

Can anyone provide any more information?
