What can you do to prevent the spread of Aquatic Invasive Species?
Aquatic invasive species (AIS), including diseases, are easily spread from one water body to the other. Anglers, boaters, construction workers, pond owners, gardeners, seaplane pilots, field workers - virtually anyone who works or plays in or around water can unknowingly transport these pests on their boats and equipment or allow them to spread via improper management practices. It takes only one mistake to potentially infest a new water body. To protect Montana’s waters and native aquatic species, please follow the rules and guidelines at cleandraindry.mt.gov.
