Despite these extraordinary times, it is still possible to safely – with social distancing – enjoy paddle sports on Michigan’s many wonderful water trails and lakes. Kayakers, paddleboarders and canoeists can also be key in the fight to protect the waters they love by identifying and reporting aquatic invasive species they encounter.

What is an aquatic invasive species?

Aquatic invasive species are plants, fish, snails, viruses, and other organisms that move into and colonize ecosystems where they don’t belong, usually damaging native species and water quality in the process.

Often, aquatic invaders are transported by humans —  as live bait, planted in flower gardens, imported for fish ponds, carried in the bellies of shipping freighters — or plant material snagged on kayak rudders and stranded in puddles at the bottom of poorly drained canoes. If a non-native stowaway is still alive when the boat splashes into the next water body, the invader could find itself in fresh territory.

Program now free for all registrants

The MI Paddle Stewards new online program from Michigan Sea Grant and Michigan State University Extension will help paddlers learn about important invasive species, how to properly clean a watercraft, and how to report invasive species. The MISIN (Midwest Invasive Species Information Network) app is a tool used by Michigan’s Department of Natural Resources and others to locate invasive species of concern. Using this app allows paddlers to help with the early detection of invasive species in their area. 

Become an ambassador for Michigan waters in five short sessions (approximately 30-45 minutes to complete each session) and spread the word on invasive species to your friends and fellow paddlers. The MI Paddle Stewards course is now free for all registrants, thanks to funding from the state's Michigan Invasive Species Grant. Participants will receive a bucket hat, stickers and more for registering.  They also will have access to complete all 5 sessions of the course until Dec. 31, 2020. Register online.

Looking for new water trails?

The Michigan Great Lakes Water Trails Working Group, comprised of staff from Michigan Sea Grant, Land Information Access Association and a variety of state agencies, local governments, paddlers, and more hosts a Michigan Water Trails website (, where users can find trail maps, safety information, and plenty of other paddling resources. The site catalogs more than 3,000 miles of trails across the state, from a loop around Isle Royale in northern Lake Superior to a Lake Erie trail that crosses the border into Ohio. Many trails move along or toward a lake shore, while others are fully inland.
