DNR wardens and county sheriffs regularly patrol the Wisconsin River, especially on weekends. Bringing glass on the river can result in a fine of over $700. Typically, a warden will approach your boat and identify themselves as DNR officers. They may ask to look in your cooler, check for life jackets, and see how everyone is doing. They are very much just out to make sure everyone is safe and following the rules. We are extremely proud to have some of the best wardens in the state on this stretch of river. If you do happen to have a glass jar that was overlooked (pickle jars are the worst offenders), it’s likely the warden will choose to confiscate the glass rather than issue a ticket if it was an honest mistake. Trying to hide your glass bottle of Fireball will not go well.
