Manitoba Natural Resources and Northern Development is reminding boaters, anglers and other people who are out enjoying the province’s lakes and rivers to remain vigilant and help play an important role in protecting waterways.

Manitobans are reminded to ensure they properly inspect and remove aquatic invasive species ( before transporting watercraft, such as boats, canoes, kayaks and jet skis. These rules also apply to water-related equipment such as fishing gear, anchors and inflatables.

Several provincial watercraft inspection stations have started operations for the season to assist with decontamination. It is a legal requirement for all watercraft to stop at all watercraft inspection stations when they are open. Operators should ensure to plan their travel accordingly.

Manitobans are reminded it is illegal to transport AIS or remove samples from waterways and take them home. Water users must be free of AIS before leaving the shore of a water body. An open-water season checklist is available at to help comply with requirements.

If AIS cannot be removed from watercraft or water-related equipment before leaving the shore, contact the Manitoba government before transporting the equipment. This also applies to contaminated items such as docks and buoys that have been kept in an invaded water body. Further information is available at

The spread of AIS is preventable and the department reminds water users to follow the AIS legal requirements: clean, drain, dry and pull the boat plug whenever leaving a water body in Manitoba. Watercraft and water-related equipment must also be decontaminated before placing the items into another water body if they were last used in:

  • an AIS control zone (;
  • an invaded water body such as Lake Manitoba or Assean Lake; or
  • a tributary to the first impassible barrier or connected water body of a control zone or an invaded water body.

Failure to do so can result in fines. Examples of set fines for AIS offences include $1,296 for possessing or transporting AIS and $2,542 for failing to decontaminate prior to entering another water body.

The province is reminding water users zebra mussels were detected in Lake Manitoba by the Narrows. All watercraft, including canoes, kayaks and jet skis, as well as all equipment that enters the water, including fishing gear, anchors and inflatables, must be decontaminated before placing them into another water body.
