AP, mine was open about the same as yours (only round) a couple of weeks earlier. Checked again this moring and it is still frozen over. We are supposed to go back into the deep freeze again this weekend. I may have to get a rock ready to luanch.
I see your adding water again to your pond. I guess the soil teatment you did last summer didn't help with your leak? Where are you getting your water from, if your source dosen't flow in the winter?
