I'm afraid youre out of luck... that is about as good as they come. Atlantic GPS maps are the best you can get that show great detail and even creek channels... but they only make those for Dale Hollow, Kentucky, and Barkley for our lakes here in Kentucky. You might want to take the hotspots you get at wally world and compare it to the online maps you find at the angling technoligies they mention on this site or fishidy.com and plug in some extra or missing info.
