IF, and that is a big IF at this point....the weather stays as forecast for the week, I highly doubt you will be hunting any flooded timber. Finding running water in the timber maybe even more unlikely. All the rivers are down and falling, making ANY flooded timber trapped and still water. Still water in 3-5 nights of 20 degree weather usually spells LOCKED TIGHT.
Now the further South your located, the better your odds are of finding water not frozen. So as in all things duck hunting it will be about location, location, location. Right now I can tell you from Hwy 64, North most flds are frozen, rivers are well within their banks and falling, and ducks are a bit thin. Where there are ducks, they are quite thick, they are concentrated and not scattered at all.
If your coming, I'd say watch the weather, hope for a warm up, and be flexible to change.
