Lots of people are scared of things that they don't know or understand.

I use Clethodim for control of grass in clover food plots. According to the label, you can't spray it on the water or let the spray drift go on the water. Don't spray heavy enough that it runs off the plant, and don't spray within an hour prior to a rainstorm or any irrigation. It's similar to Post, different chemical, but Post is also a grass specific herbicide.

I'd use it, being careful to apply it at the labeled rate, and be very mindful of the spray near the water, and I'd pay a lot of attention to wind direction and wind drift of the spray.
