Turtle ID Help - Zoo Knoxville

Could be Pelomedusa subrufa? Not sure what other Pelomedusids are present in North American zoos.

@Swampy Of course it's the one sign I took a photo of that came out blurry.

I think I can make out Pelomedusa on the sign, but the word after that only has a few letters. They were also exhibited with Caiman Lizards if that helps - location wise.

Looks like a Podocnemis to me, perhaps unifilis?

@Ituri oh gosh you're right, even still got traces of the yellow spotting- Podocnemis unifilis it is.
