RE: Ice Conditions at Southeast PA Lakes
I fished Antietam Lake a week ago (Berks County, near Reading / Mt Penn) and the ice was at least 6" up to 10" - 12" in places. With this snow cover and cold temps it will only get better. I'm sure anything in the area is just fine right now. You just have to be careful on the lakes where there are flowing creeks feeding into them, those places on the lake will have thin or weak ice... look for where everyone else has been getting on the ice.
