Starting July 1st, boaters will be required to drain all water from boats and equipment before leaving a body of water.
The drain plug must also remain removed or opened while transporting the equipment.
The DNR will post the new rules at area boat ramps to remind boaters.
The goal is to prevent the spread of invasive species such as zebra mussels and Eurasian watermilfoil. Both of which can threaten native fish.
