Crawdaddy, I waterfowl hunted in central MN every season for 24 years. Last year was the first time I didn’t go. During the course of those 24 years, the duck hunting slowly just got worse and worse. Some seasons were better than previous years and some were worse, but overall the pattern was evident to me: not as many ducks. I’m not going to blame it all on deteriorating habitat, weather, or migration shift because I know for a fact that much of it was my own fault, as I basically stopped scouting for birds ahead of time. I would just assume that they would be there at the same spots I always hunted, and over time that was just not the case. I never went a lot, but I’d go about 7 or 8 times/season and harvest about 40 ducks. Then it was about 3-4 times a season and 20 ducks. The last few years I went it was 1 or 2 times per season and maybe 5 or 6 ducks. I really enjoy a good waterfowl hunt and have all the gear, but I couldn’t justify the cost of the stamps and the time commitment anymore.
That being said, if you are willing to scout and look ahead of time, you can still succeed. The best way to scout is using your own eyes. If you see ducks there, obtain permission to hunt it if you can. With the drought this season, small potholes may honestly be completely dry so you may have to focus on bigger water. There does seem to kind of be a lull after all the local ducks have been shot at or migrated, and before the birds from up north arrive. If we get an early cold snap followed by a warm spell, that usually does it. Hopefully others will chime in an offer their advice on this as I’ve been out of the game for a season now. I know there is an early teal season in September followed by a youth waterfowl season, plus an early goose season, so pressure on birds before the general opener could also be a factor.
