A further section notes that Canadian populations are found in the St. Lawrence River watershed, from Ivy Lea, Ontario to Saint-Pascal, Quebec.

To the right of the infographic, a map of Ontario shows, by an overlaying rectangle, where the related population is found. Another map on the left of the infographic shows a magnified view of where the population is found by use of splotch markings, with lakes Ontario, Erie, and Huron labelled.

A final section on the infographic notes that activities in or near water can harm aquatic species, and lists what you can do:

  • prevent contaminants from entering water
  • report any invasive species sightings to DFO
  • keep your shorelines natural
  • protect sensitive habitat; contact DFO before doing any in-water work
