What are AIS?
Aquatic Invasive Species, or AIS, are non-native plants, animals, or other organisms that invade freshwater and marine ecosystems causing harm to the environment, economy, recreation, and traditional resource use. Once introduced, these species can spread rapidly, outcompete native wildlife, and permanently alter aquatic habitats.
Two major threats to Northern Manitoba waters are Zebra Mussels and the Spiny Waterflea:
-
Zebra Mussels attach to boats, docks, and intake pipes, damaging infrastructure, and can harm fish populations.
-
Spiny Waterflea are a small freshwater invertebrate that consumes large quantities of zooplankton which are a vital part of the food chain.
AIS can be transported on boats, trailers, fishing gear, and other water-related equipment like beach toys. To prevent the spread, always Clean, Drain, and Dry your watercraft and gear before moving between water bodies.

What We Do
We lead a coordinated effort to prevent the spread of zebra mussels and other aquatic invasive species across Northern Manitoba. Through public awareness, ongoing lake monitoring, partnerships with local and provincial governments we help protect our region’s lakes and rivers for all to enjoy.
Government Liaison
02
We work closely with the Province of Manitoba and local municipalities to strengthen prevention efforts, and improve communication between government departments, enforcement officers, and the public. By acting as a liaison, we ensure that concerns are heard, updates are shared efficiently, and prevention strategies are aligned across all levels of authority.
03
Education is key to prevention. That’s why we develop and distribute easy-to-understand resource materials tailored for individuals, businesses, recreational users, and educators. Whether it’s signage along highways or at boat launches, tools and checklists for cottagers and owners of watercraft, we help ensure everyone has access to clear, accurate information about AIS and what they can do to help stop the spread.
Our work is made possible through funding opportunities, and the passion of dedicated volunteers. We apply for grants, seek partnerships with like-minded organizations, and gratefully accept public contributions to support our programs and outreach. We’re always looking for enthusiastic individuals to join us—whether it’s helping at events, sharing information, or lending skills behind the scenes. Every bit of support makes a big impact.

Who needs to stop for inspection?All motorized and non-motorized watercraft—including boats, canoes, kayaks, SUPs, and inflatables—must stop at open watercraft inspection stations along their route. Water-related equipment, such as anchors and fishing gear, that has been in a water body will also be inspected. For more information, please see the Province of Manitoba Website.
-
Where are the watercraft inspection stations located?Watercraft inspection stations are set up at key travel routes and high-traffic lake access points throughout Manitoba during the boating season. Locations may change based on risk levels and available resources. 📍 For the most current list of inspection station locations and hours, visit: Province of Manitoba Website Make sure to plan your trip accordingly—all watercraft must stop at open inspection stations along your route.

Why should I Clean, Drain & Dry?Cleaning, draining, and drying your watercraft and gear helps stop the spread of zebra mussels and other invasive species that can seriously harm our lakes. These simple steps remove hidden invaders before they travel to new waters. Watch this quick video to see how easy—and important—it is!
-
How do I Clean, Drain & Dry?After leaving any lake or river, follow these three steps: Clean – Remove all plants, mud, and debris from your watercraft, trailer, and gear. Drain – Empty all water from coolers, bilges, live wells, and any other compartments. Dry – Let everything dry completely before launching into another body of water. These simple actions help stop zebra mussels and other invasive species from hitching a ride to new waters. Watch this quick video to see exactly how it’s done:
-
What should I do if I suspect or find zebra mussels?If you think you’ve found zebra mussels—or any aquatic invasive species—report it immediately to Manitoba's Aquatic Invasive Species program. Early detection is critical to preventing further spread. Call: 1-87-STOP AIS-0 (1-877-867-2470) Email: AIS@gov.mb.ca Online reporting form: gov.mb.ca/stopais If possible, take a photo, note the exact location, and avoid disturbing the area until authorities respond.
-
What is decontamination, and when is it required?Decontamination is a more thorough process used to remove or kill any zebra mussels or other aquatic invasive species that may still be attached to watercraft or gear after use. It involves hot water treatment, high-pressure spraying, or drying times of up to 30 days, depending on the species and water body visited. In Manitoba, decontamination is required if: Your watercraft has been in a zebra mussel–infested water body, It cannot be fully drained, or You’ve been ordered to decontaminate at an inspection station. Learn more about what’s required and how to prepare: Province of Manitoba

Awareness & Outreach
01
We increase public awareness about the threat of zebra mussels and other aquatic invasive species through both online campaigns and in-person events. From social media education to booths at community gatherings, our goal is to inform and inspire responsible action. Every conversation helps spread the word about how simple habits—like Clean, Drain, Dry—can prevent the spread of invasive species and protect our lakes for future generations.
