Information Bulletin - Enhancements to Aquatic Invasive Species program for Clear Lake

Issued: May 16, 2023

Parks Canada will be strengthening its Aquatic Invasive Species (AIS) program in Riding Mountain National Park for 2023. These changes are in response to the positive test result confirmed from Clear Lake, for zebra mussel environmental DNA (eDNA).

The boating season will start on June 1, 2023.

To obtain a permit to use a trailered boat in Clear Lake for 2023 boat users must:

  1. NOT have been in any other water body in 2023
  2. PASS an initial inspection before June 15

Parks Canada will also be bolstering the inspection and decontamination program for self-propelled watercraft, beach toys, etc. All canoes, kayaks, stand-up paddle boards, inflatables, beach toys and all other items to be used in the waters of the national park will be required to undergo an inspection, and if needed, decontamination process before being allowed to launch inside the park.

This balanced approach will help ensure the long-term health of Clear Lake remains intact. Parks Canada appreciates the strong connections people have to this lake and area. Parks Canada sought input from Indigenous partners, governments, and stakeholders including the tourism industry, local business community, and townsite cottage and cabin owners. The overarching message we heard is to protect the health of Clear Lake.

This enhancement to the existing AIS program helps mitigate the threat from aquatic invasive species while allowing visitors to access the lake in a safe and sustainable manner.

These measures are in place for the 2023 season and are subject to further change should conditions require.
