sorry I misssed that. Its current deepest point is 5 ft, and that is consistent around the edge so probably about 60 pc is at that depth. There is a ridge where the excavator couldn't reach which is about 2 feet deep.This is well covered with weed and the FHs seem to have moved in and breeding well.This overall depth will increase by about 4 ft during the winter, but then the ice must get at least 18 inches in thickness
