With it being full, i was also wondering if there is something we can do to attract ducks to the river this late in the year.
Too late to plant anything. And river bank not really a good place to plant anyway (seed gets washed away, and not really a drawdown like a pond). Your best bet is to just go scout it, see if and where the ducks want to be. Then set-up in that spot the next day and shoot’m in the face. That is what duck hunting is all about.
If you scout it and there are no ducks, you could pick a spot and try and pull down some ducks, but set your expectations low.
You could also think about getting a backhoe down there and make a flooded area.
