I am a kayak fisherman with no electronics, so I have to rely on what I can see above water and depth maps. I am also limited on how much water I can access and cover since I'd prefer to stay away from main lake spots because of the crazy boat traffic. If I name some bodies of water, would anyone be able to help suggest any spots to target for pre-spawn/spawn, and even what I should look for once post spawn/summer rolls around? 

Summer is probably going to be just fishing the shallow lay downs and grass edges. Generally want to be above the thermocline but hard to tell without electronics. I would try going on navionics chart viewer to plan if you were making one.
