It depends upon what type of waterfowl hunting you want to do. In recent years, we've found field hunting in picked small grain or corn fields very effective and a lot of fun, especially if you don't have a retrieving dog.
For this type of duck, goose hunting, scout the back roads in farm lands from about 3 pm to near sundown looking for numbers of geese and/or ducks feeding in picked grain or flying out following to where they land and feed. Mark the spot visually from 2 side alligning with power polls, signs. Then find and get permission from the land owner. Even sometimes posted land the landown might let you, if you are personable and ask.
You need a few Canada Goose shell decoys and a few silhouette goose decoys, some burlap to cover yourself with. Get out to the exact same spot you saw the field feeding geese / ducks the evening before light the next morning. Set up you decoys in family groups not to close and lay down among them covering up with burlap and any stubble around. Get you duck / goose calls read, lock n load. Give the birds enough calling to get them to commit to you but not to much. If you have a goose flag wave it when the birds are a long way off to get their attention, then put it down hidden. Expect ducks, usually will come in first nearly at first light. Geese usually within the first hour up to 11:00 am. Then pick up your spread and clean your birds. Do it over the next evening (scouting) for the next day's hunt!
