Knowing the area where you are launching from would help out alot.
As others have mentioned, the bass are everywhere holding on structure. Dragging tubes, jigging spoons, crankbaits, etc.
The walleye are deeper, but starting off of Port Maitland, Port Colborne would be a good start. Everyone has their favorite lures, but I never seem to go wrong with harnesses. Just finding the hot color can be some work.
Don't know where you are located, but talking to other anglers at the launch you use will no doubt point you in the right direction.
