Well where do I start. For first time visitors to the lake I would recomend the area on Highway 229 just west of the visitor center. There is a turn out on the left (if you're traveling west) close to the base of the hill. That is where you want to park. You must go past it and turn around then come back. You can't turn left while going down the hill. The water temperature will vary depending on the depth you choose to dive. For the most part if you plan on going below the thermocline (almost always at 27') you will need full protection. I wear 6mill from the top of my head to the tip of my toes. Above the thermo almost any level of protection will do. Most who dive above, shed the hood and gloves and keep the zipper 3/4 down on the jacket. I know that there is a zillion methods to calculate the required weight but it boiles down to body mass, water displacement, and gear configuration. With my out fit (single tank, very high quality wet suit, stainless back plate and a steel 80) I only need a 6 pound weight belt and I'm not a small guy. I may be short but not small. My wife feeds me well. Wearing the exact same set up and a lower quality suit I need 12 pounds. So I guess the short answer is take the time to adjust you weight before your first dive. Oh ya if the old highway enters the water you're at the right spot. I MAY be there Saturday morning. The Vis is good. If you want to see a few of the bigger bass dive by the curtain (obvious when you're there). If you dive along the road look under the rocks for the crawdads. Some of the bass will take them tail first right from your finger tips. Good luck and have fun.
