Found small green tree frog near the water edge at Grand Falls Park.

Yesterday evening while walking my dog at Grand Falls Park in Joplin, I noticed a small green tree frog hopping around near the edge of the water. It seemed a bit lost and didn't want to jump back into the water. I carefully picked it up and brought it home, but I'd like to find its owner if someone has been missing it. I'm keeping it safe in a small terrarium for now.
