found this today and thought i would share with you all,,while checking out the results of the just completed tournament on KY.lake i found a site called angling technologies mapping ,not sure if i like it just yet but pretty interesting to tinker with.i think you would need dsl or something other than dial-up to view correctly but see what u think...looks like you can zoom in to almost any lake of any size but not all lakes have much detail and then again some of the bigger lakes have lots of interesting stuff......
try this maybe it will work,,,,,www.findyourwater.com
looks like the same place....
