I have been busy lately moving house (hate moving ) but yesterday a friend and I climbed Fan Brycheiniog (http://en.wikipedia.org/wiki/Fan_Brycheiniog)
Here is a bit of background info on the lake:
Llyn y Fan Fawr (Welsh: 'lake of the big peak') is a natural lake in the county of Powys, Wales. It lies at the foot of Fan Brycheiniog, the highest peak of the Black Mountain range within the Brecon Beacons National Park.

This is the only photo I have had a chance to edit so far, a lot of them didn't come out that well because after this point it started to get really misty and at the peak, visibility was really bad and there was really fine snow.
C&C Welcomed, as always
