AnswerThere are snakeheads in Texas, just not recorded. There is a pond that is connected to Lake Ray Hubbard that I have caught snakeheads in and they are in the lake too would be my guess since they are connected. It is just a matter of time before they start going out of control. I reported to tpwd but they didn't do anything.
