What about bird of prey? Do you think they will get to him? That is what I would be concerned about.Cool find and great rescue!
If you live near the lake, or any body of water, and you have a rubbermaid tote , you can sink it in the water in a shady spot (so long as it gets shade all day!!) and put the little guy in. That's plenty of room for him to recover, safety and will be the temps he's used to.
Once he's fully recovered, you can just tip it over!
