The best lake maps I've seen are the ones that the U.S. Army Corps Of Engineers put out. They show the actual elevation of the contours, but you need to keep up with the lake elevation. No hot spots though, just a contour map with channel markers shown. The markers are not always exactly where shown, in some cases not there at all. My advice would be to pick out some of the larger bays with deep creeks, pick up the ledges on the depth finder and work them up to shallow water. You will find plenty of cover to fish. These lake claim several lives every year, unfortunately common sense would prevent most losses. The only time I have feared for my life was in a bass tournament on KY lake years ago, five boats went down that day. Luckily only some pride was hurt. I always heard the good Lord looked after small children and fools, he had his hands full that day.
