Live stock tanks would not work for a turtle as they need a safe place to bask
in the sun for hours a day.
We constructed an island in the middle of our pond for turtle basking, we also
had several sheltered places around the edge of the pond for them to get out
and bask. They were hidden enough that the two labradors never noticed them and
the turtles would continue basking every time a gallumping labrador went on by.
