Another interesting "level" is to mark waypoints on your Google Earth program then transfer them to your boat's electronics.
Ideally, if you happen to look at some of the historic images and find times when your target lake is really low, you'll be able to make out some things and mark those spots, too.
Take a look here . . . I happened to see it today.

Transfer waypoints from Google Earth to boat electronics Thanks for the tip Brad. Have you tried to do this yet? I did it today. Was way easier than I expected and worked great.
I never have, saw it and thought to myself what a wonderful idea to mark waypoints, to transfer them to electronics. As electronics get better and better, my guess is more and more "auto-pilot" features might allow boaters to navigate between a boat ramp and waypoints . . . to avoid stumps and more. I would suppose lake areas, say the north end of Palestine, would be fished more actively if one could navigate the "gauntlet" of obstacles. Anyway, I think Google Earth is a really good source to find spots . . . glad it was an easy transfer for you! Brad
