If I'm getting your question right, I would assume that as long as no water treated with rotenone made it's way to the next pond there would be no need to neutralize it. Additionally if there is enough time for the rotenone to break down, that would work too. As you know that depends on water temperature.

If pigs could fly bacon would be harder to come by and there would be a lot of damaged trees.
