As you can see

 The area of open water continues to expand, even with the temperatures dropping like a rock. Yesterday morning there had to have been at least a thousand ducks and geese around or in the open water first thing in the morning. Not good for lake nutrient loading. Not much we can do about it. Today there are many less. Flocks cleared out shortly after daybreak as usual. The dark line to the right of the picture on the ice are all geese.
