And anyone want it? Lol. I haven't a clue about water turtles. Any info about this? Dropped off by a friend. I need to rehome it soon.

We have a 2000 gallon pond. We could give the turtle a home. We live in Southern California. Where are you?

I'm in central CA near modesto. Any chance you're coming up this way soon?

Looks like a Yellowbelly Slider, Trachemys Scripta Scripta, to me.
