Fill your tank up as full as you can....EXCEPT make sure it's not so full that the turtle can reach the edge and escape. Turtles are very strong and athletic. If they can, for instance, stand on their basking platform and get their front paws on the edge, they can probably lift themselves all the way out.
RES in the wild live in lakes and ponds where they love to swim and dive. They will be happier with deep water. If they aren't used to deep water, you'd probably better introduce them to it slowly. For example, add an inch every few days until you reach the level you want.
