Ditto what PMaloney said.
I can attest Burnett's Pond (Savoy) and K of C Pond (Plainfield/Hawley) had 4 to 5 inches of ice this past weekend, and presumably have more by now.
Given the lower elevation, larger size and "flow" on Cheshire Lake, I would expect the ice there would be thinner than the others I've just mentioned, but (partly for that reason) I haven't been out on it or checked it out yet.
