Well I can not help you on the ice conditions of the followings lakes I mention here. But if you are in the Dover , Nh area you can access the border lakes just a few miles north of Dover via the Spaldding Turnpike/Rt 16 easily. They are Milton Three Ponds, Horn Pond and Great East Lake. A little further east into Maine try Square Pond or Mousam Lake in Acton ,Maine area. These 2 are also accessible from The Great East Lake area via the back roads.
