It's an extremely mellow dive, the max depth is only 12', so you are basically swimming in a giant swimming pool with fish, a current and the potential for tuber loot.
I'm going in the morning again, I will probably be going most weekends that I don't have a dive someplace else going on.
You definitely want to get there early. I get there around 7AM, park in Solms park (you can park very close that early), gear up at the car (make sure you have a key you can take under water with you or that is in a water proof container), lock everything in the car, go down the hill and hop in. Watch the steps, they are slicker than snot.
By they time you run out of air (I generally get a total of 85ish minutes out of a tank, leaving it at 400psi), it will be about 9AM assuming you got in at about 7:30 or so. Tubers and whatnot are just showing up, so you will only be out there with the occasional fisherman and other divers (some mornings their are 7 or 8 surprisingly).
It is a very mellow place to dive and I probably like it a little too much for what it is.
Fish were especially friendly today, I had a school of about 20 following me around wondering what the hell I was doing.
