Several ways to get maps, punch in Cave Run Lake, KY on your PC , it'll bring up many sites. Find the one from the army corp of eng's , they'll send you a free map , it doesn't show depth or contour lines , but it's a start. The best map you can get is Hot Spots map, it'll show everything you need. If you dont want to send in to hot spots, you can purchase one from the guide services? there or the local bait shop. I'll be down there trying the same things in about a month, it'll be the first trip to the cave for us.
