I've got a Fishing Hot Spots map, actually there are two of them for the Rock, east and west sections. I bought mine a couple of years ago at Walmart, or you can order them online at www.fishingmaps.com. The maps show depth contours, road beds, sunken bridges, timber, bank composition, such as chunk rock or gravel, boat ramps, in addition to creek names etc., I use mine a lot, much better than my Navionics maps on my GPS.
