well heres how it looked at 3.30 this arvo. The weather is even colder here today with more ice about.
I didnt leave the carpark at Elinor ( Bl**Dy freezing when that sun dropped) but it looked like the dam wall had a sheet of ice going out 30 or 40 yds out to the big copse ( you can see it on the photo below).
And the western ends (either side of the pylon) were both solid with ice. It looked like 2/3 of the surface was free of Ice.
I would definately ring before you go.
The track into Elinor at 3.30 today.
