We didnt use to have ducks winter over in this stretch. last few winters, we have. 18 below, and there are about a dozen here, usu in the water; here some are in the far right tip of the dark cure of open water on the right of frame. A decade ago this entire stretch usually closed by around Jan 1. It will likely close in next hours, and open water will be hard to find. Not sure what the ducks will do.
