I was there this past weekend during Labor Day and the visibility was really good. The guy at the Brady Mountain dive shop said visibility was just starting to get really good. That was their last weekend for being open. Some places we dove had at least 10 to 15 feet of vis down to 30 feet, before it was kicked up by lots of divers, but below the thermocline, it really opened up. Some deep divers reported 30 to 40 feet plus or as far as their light would shine. The first thermocline was around 30 to 35 feet. I was diving with a big group from Dallas and we rented a big pontoon boat for 2 days from the "Spillway" shop.
