I found this interesting-looking fish in Lake Frances in Nescopeck State Park in Pennsylvania. The PA Fish and Boat Commission stock Lake Frances with brown trout and native brook trout. This looks like it might be a tiger trout, Salmo trutta x Salvelinus fontinalis, which is a hybrid of those trout. It was about 1.5 ft. long.
