Hey Scott,
Its been a number of years but you and I used to email a lot long ago. I have a friend who built a nice large enclosure where he kept EBTs and other sympatric aquatics including spotteds and painteds.
He had a filtered shallow pond, about 8" at the deep end with plenty of slope for the box turtles to find their way in and out easily.
Good to run into you again and glad to see you still keep your boxies.
Cheers,
Paul
