Right now the shad are running, if your lake has them, find an inflow with some current. The bass won't be far behind. We've been slamming them in 40-50ft of water suspended anywhere from 15-20ft down with vertical presentations.. Gotta find the bait balls but once you do hold on.. Was out again lastnight and put a few cows in the boat with a lot of smaller fish in the mix as well. Electronics are an absolute necessity when it comes to this type of fishing.
If you don't have electronics then look for fish actively feeding on the surface. Once you do, you'll want to run something like a Rapala DT10/14/20 in that area. Casting open water when the smallies are feeding on baitfish below can be a riot.
Flutter spoons would be another option as well.
