Prefers the deep or shallow parts of slow-moving rivers, large streams and lakes. Needs plenty of vegetation, muddy bottoms and abundant basking sites.
How to Find
This turtle is rarely seen away from water. In the spring, males can be seen swimming in front of females as part of the courtship dance. Use binoculars to survey basking sites along slow rivers. If you get too close, the turtles will drop back into the water.
