Often, another good bet for finding bigger trout can be the transitional sections of a stream where it is no longer good cold water habitat, but isn't quite decent warm water habitat yet either. I don't know enough about Franklin County to give you local examples, but over the years, friends and I have taken some really large browns out of a number of NW Pa. streams while fishing them for smallmouth. Usually, these fish will come out of the lowest stocked section of the stream or the next section below where stocking ceases. As a general rule, this sort of fishing is a closer cousin to musky or big pike fishing than regular trout fishing in the sense that there is a high hours expended to fish hooked ratio and in many cases, you'll locate the fish long before you actually catch him. I also tend to think that the more fertile the stream is overall, the better candidate it will be for this sort of big fish hunting. That is to say, the transitional water in a relatively fertile stream like Oswayo Creek or a large limestone like the Bald Eagle will provide better big fish hunting than someplace like lower Kettle, the Loyalhanna or the Loyalsock, etc. for example...
