I'd be up, but I'm busy all weekend, and it's closed on Labor Day.
I was there Saturday morning, and the visibility was surprisingly good (until all the students came through
); I'd say about 15 feet. As in, I could see things and divers 15ft away. I could even see dive lights 30 some feet away. But after the rain, I'm not sure that visibility is still so good.
