Trout will drive you nuts!!!! You NEVER know what they are going to do, or where they are going to swim.
I have caught them really deep......and I have caught them right under the ice (about two feet down in deep water).
My best suggestion would be to stagger your tip-ups, suspending some baits deep, some shallow, and see what happens. If the shallow baits start getting hit, move some of the deep ones up near the top.
Best results for me have been with shiners (medium size).
You can also try jigging (try a jigging Rapala, or Swedish Pimple tipped with shiner head or tail) at various depths until you locate fish.
Be sure to ask your local tackle shop owner for directions to Trout waters .... you have to know where they are first!!!!
Good Luck
