Checked a couple of ponds in Western Ma today. Each place had about equal amounts of black ice to snow ice ratio.
Center Lake - Becket, MA: 6-7" (edges by the beach was open about a foot. one guy fishing but said it was slow.)
White Lilly - Otis, MA: 7-9" (Recent holes drilled on top)
Norwich Lake - Huntington, MA: 6-8", (couple of groups, quads on the ice.)
***Creepers suggested at each of them!
