Protect Your Waters (MN DNR website)

Prevent the transport of zebra mussels, Starry Stonewort, Curly-leaf pondweed, Eurasian watermilfoil and other aquatic invasive species (AIS).  Invasive species are species that are not native to Minnesota and cause economic or environmental harm or harm to human health.

Minnesota waters are threatened by aquatic invasive species. It is illegal to transport any aquatic plants, zebra mussels, New Zealand mudsnails or other prohibited invasive species, or to launch a boat or trailer with these species attached.
