Try to get a topo map of the lake. I know when I lived in VA the Fish and Wildlife website had very basic maps that would locate, the depths every 2 feet, docks, dams, man made structures. It wasn't the best but was helpful in locating drop offs, deep water coves etc. Also read up on what season you are in(spawn, post spawn etc.) in your area and use it as a guideline to locate the fish as well as identify what techniques may work well. And lastly, I know I keep posting it, but the big thing is to not get too close to where the fish are. if you can stand back off the bank do so, cast parrallel(forgive my spelling) to the shore etc. Hope this helps good luck.
