Yellow Smoke is a man made lake, has some decent diving most of the year, if it storms the lake gets mucked up for about a week. There are some great underwater forest that were left when the lake was built, they house some good life, they are great to dive threw. Best diving is over by the damn, and the handicap fishing dock. Decent practice diving around the boat entry dock and the swimming area. To check the visability i go to the end of the boat dock and look down there is a large bolder at the bottom if it can be seen the visablity is around 10 feet plus.. If you want to give the lake a try hit me up and i am more than happy to go diving!! Good Diving! 24-medic7@live.com
