Where is this Lake? I have never heard of it? But on the lakes around here...they may be frozen around the edge but the middle be clear ( unfrozen ).Ducks and other waterfowl will tend to paddle in water to keep an area open for drinking purposes. When they can no longer keep the area from freezing, they fly somewhere else to get water.
