Best Locations and Seasons for Sightings
I saw this turtle species only once in Rapids Park Lachine at a spot which is usually occupied by Painted Turtles.

"x" indicates the species was observed, while "-" indicates no observation. Lack of observation doesn't necessarily imply that the species is absent. Data is derived from my park visit journals.
Identification and Similar Species
Tricky to identify as this species looks very similar to the Painted Turtle. The lack of red color on skin and along the border of the carapace is a hint. The turtle shows clearly viewable light markings on skin.
