Before you drive to ames farm you may want to call them. They are on the web. I believe you can no longer launch there unless you are staying there. Some issue with the town of Gilford I think.
There is some open water at the end of the river on both Little Squam and big Squam.
I've seen a boat in little Squam for the past week. Not much room, but getting bigger.
Still solid ice in most places.
