Did I bet (reraise) too little on the Turn?

I doubt that your getting him to lay it down without a massive overbet (probably not at all since he's short - $9 with $3 invested). He's drawing to the nuts with top pair on the river. He had every reason in his mind to come along. I would have too, kicker would also have an influence on my call.

Also raising preflop and the flop doesn't really scream to him worry about the flush draw, so I don't think he felt that you had it even after the raise. Your flop raise was more designed to push out flush draws from his/my perspective for this level of play.
