My grandkids were skating on Ball Pond at the boat launch end. It is shallow at less than five feet out for a couple of hundred yards to where the pond gets wider so it freezes first and is safe now. The rest of the pond is controlled by springs so I would not trust the center of the pond. The outlet cove might be safe along the shore out to about fifty yards from shore. I don't like to be the first one on the ice though so be careful.
Ball Pond was safe in the cove where the boat launch is located. MY grandkids were ice skating there and one person dragged a sled at to the area where the shallow cove water drops to 20' but I think the ice was only about 3 inches out that far so we did not go out that far.
I was at Kettleltown this morning. Sloppy edges, and 4 inches 10 yards out. Only made it out another 200 feet or so and it was barely 3 inches in 3-4 feet of water. Gave it 10 minutes and left.
