I just got emailed the survey from the MDNR with questions on the 2020 season, plus a chance to add comments about season dates, bag limits and other matters pertaining to waterfowl hunting in Michigan. I'm not sure how widespread the surveys are this year, but these results are used by the waterfowl workgroups to set dates, and reviewed at CWAC before the voting. The last survey had a 3% response rate, which is a little disappointing.
As an example of how this works, the 2018 survey results clearly showed that most hunters in the Saginaw Bay Area preferred that the bay move to the middle zone, so that option was presented to CWAC for vote. After CWAC voted in favor of this move, the Natural Resources Commission again used the survey information to approve the change.
Please take the time to fill out your post season survey if you get one!
