I would start sinking brush on the structure you mentioned. That will give you some good places to fish next summer. Place some on secondary channels leading to and from spawning areas. Those should be good for pre and post spawn fish. Place some on main lake drops near channel bends for summer fishing. Also look for flats or bays in the 10-15ft range that have lots of submerged vegetation. Drop some pallet beds in those areas and you should have a summer hot spot that is almost impossible to see on a fish/depth finder. For the upcoming months, look for shad schools in any deep bays, creeks that sort of thing. If your lake has any deep tributaries or narrows that shoot off of the main lake, that is where I would search for ledges and schools of bait fish this winter. If you don't have anything like that, search the main lake structure for shad. Hope this helps.
