I found this on the net.
What do turtles do in the winter time?
Thousands of turtles prepare for winter by going deep into the water or by digging a deep burrow. They will slow down and hibernate for as long as the weather is cold. Then when the spring comes, the turtles will warm up and become active again. Once again, they will look for nice warm places to sit and enjoy the sun.
I have a lined pond and would not appreciate a turtle trying to burrow in the bottom of my pond with his very long sharp claws.
