I did dive at Lake Murray this last weekend, though on Sunday instead of Saturday. There was a noticeable absence of divers!! Perhaps it was the 4 or so foot vis....The water temp was fairly toasty in the upper regions though it was around 66 degrees at 52 feet. The boat was pretty full with 8 students working on their OW. I dove with a couple of guys who were with their friends but were already certified. After one dive, we were celebrating our navigational skills in that we surfaced right by the boat. That is until we noticed that it had come untied and drifted away from it's original mooring!! It was certainly good for a laugh.
