The lake is Kangârssûp Taserssua and the ice holding it back seems to be about 500m across. I don't think it will hold for very many years.

Not recently atleast. It had taken the lake many years to fill that high. Older images I see on Sentinel-Hub show the lake mostly filled with broken ice and at lower water level. Now that the big flood has carved large channels in that ice I doubt the lake will ever fill very high again.

Location is east of Maniitsoq. Can't seem to edit my first post to add location.

Another one bites the dust. A lake this time. Lots of sediment gone from downstream too. The days inbetween were cloudy on Sentinel-Hub playground.

That is a different, smaller lake in the area, about 20km northwest from the big one. There are quite the number of lakes in the area and they seem to be high as the whole western Greenland is melting like crazy.

The lake in the study actually seems to be draining at the moment(unless it has gone empty in 2 days)

This lake stays frozen most of the year but everything is warming and the icesheet holding it back will melt one day and the lake should drain, atleast partly. Might even be a big flood in a few years(decades?) as the lake is 10km wide. It's looks to be draining to north-west now, but if there is solid ground under that ice there the water level could stay high and later drain from north-east or south.

Anyone know if the lake has a name or what the mountains to it's north and west are called? I'm thinking the one to west is Sukkertoppen?

Picture is from end of august 2016 when the lake was mostly ice free.

So much sediment flowing to the fjords already. And new dark ground being uncovered every day. Looks like it could be a bad year for Kangerlussuaq harbor.

Do the meltwater streams hitting the ice stream from the side have any real effect on the rate of ice export through Jakobshavn Isbræ? There seem to be some clearer areas where larger streams join in.

And it looks like a new stream might be forming close to the calving front too.
