I live on the Marlborough/Glastonbury line. Consider it central east of the river. Closest water to me is Marlbough Lake(private,residents only) but I stopped to see how the ice was doing as a guide to other spots.
Ice was not safe as the edges were still showing water. There was ice but it is definitely not safe.
I could see open water in the middle of pond.
Last week the lake was wide open and there were two guys fishing from yaks.
Be safe out there.
