Spinners and spoons do the trick. Rainbows enter streams to spawn in the spring, while the brook trout spawn in the fall. Rainbows are also relatively easy to catch, as they will eat almost anything. Bait works well. Rainbows find worms irresistible.
Minnows are also a good choice, as well as, corn, cheese and macroinvertebrates.
Figure out what works best for you. Lures are great. Spinners, spoons and plugs all work. Pick your favorite. Since flies are bows favorite, check the hatches and you will do well.
