If you’ve been on the Mississippi River, you’ve likely seen Wisconsin DNR conservation wardens teaming up with the U.S. Fish and Wildlife Service and conservation law enforcement officers from Minnesota or Iowa.
The river is a massive draw for outdoor enthusiasts, boaters, anglers, researchers, tourists, and residents. With that influx of activity comes the need for lots of education and, when necessary, some enforcement. It is also so big that it crosses state borders and is home to federal refuge areas.
The most common time agencies form teams is during waterfowl hunting season. Having a partner is especially beneficial on season openers and busy weekends. Working together also keeps us on the same page when it comes to providing valuable education and, again, if necessary, enforcement actions.
Whatever agency you see us doing partner patrols with, know that each agency shares the goal of keeping the public safe and protecting our natural resources.
Bucket List Reputation Draws Many, Unwritten Rules Help
The Mississippi River is a common “bucket list” hunting destination for many waterfowl hunters. The vast amount of publicly accessible waterfowl habitat draws hunters from across the country during peak migration. This also means there can be overcrowding issues and user-conflicts during peak times.
Federal and state law enforcement officers often get called to address these user conflicts. Most of these conflicts can be avoided with common sense. However, here are some unwritten rules to help everyone enjoy their waterfowl hunts and respect others on the water.
DNR conservation wardens look forward to hearing your hunting stories this fall in the field.
