I've been going out and trying to work on identifying structure, and how to fish it. I've been looking at satellite images to get hints, and then finding road beds, humps, ledges etc with my graph, but it got me thinking. If you were able to visit a lake that for the purposes of this discussion was void of all water and walk around with a GPS, what kind of stuff would you mark? Then once our hypothetical reservoir was refilled, how would you fish these areas?
