GILGIT: Supra-Glacial Lake formed at the Shisper Glacier in GilgitBaltistan has started receding with a water discharge of 200 cusecs to 220cusecs per day below the surging glacier which ruled out risk of glacialflooding, citing Gilgit Baltistan Disaster Management Authority state radioreported.
According to the GBDMA, it is routine flow of water which usually pours insummer season at 400 cusecs.
The satellite images received by Pakistan Meteorological Department showthe glacial lake at Shisper Glacier to be contracting which had mitigatedthe disaster risk, an official said.
There might be two reasons for plummeting size of the glacier, mainly undersurface discharge of water and the upward movement along with thepenetration of the glacier into lake which consequently got submerged intothe glacier, official said.

The isotopic analysis would help determine the source of water dischargingbeneath the glacier as at present it was not for sure either the waterrolling down was glacial lake or the glacier’s melting water.
