It’s National Invasive Species Awareness WeekMontana’s waters are under the threat of invasive aquatic plants, animals, and diseases. These non-native species can flourish in new locations because there are no natural predators or environmental conditions to restrain them. Once established, AIS can harm our native plant and animal species and devastate aquatic habitats.

AIS can threaten boating and fishing opportunities, irrigation and ag production, hydropower, and water infrastructure systems. Recreational boats are the most common way AIS are spread.

All boat owners (both motorized and non-motorized) must stop at all watercraft inspection stations and always follow the steps of Drain. Dry.

  • Clean off all mud, plants, and animals from your boat and trailer.
  • Drain water from the bilge or anyplace that can hold water.
  • Dry your boat and gear to ensure AIS are eliminated.

Follow these steps every time you leave the water. Stop at all watercraft inspection stations you encounter. If a boat enters Montana from out of state, it must be inspected before launching. Prevention is our best defense against AIS.

Help protect Montana’s waters from Aquatic Invasive Species. Always Clean Drain and Dry you’re your boat, trailer, and fishing gear.  Stop at all watercraft inspections stations.
