I recently moved to Glenside, Montgomery County from Warminster, Bucks County. There is very little trout fishing in Bucks County. I know that a stream like the Neshaminy gets stocked early in the year, but it doesn't sustain trout through the summer. As was stated above, you might find a few holdovers here and there, but very few. The only legitimate trout stream with some reproduction and decent fishing throughout the season that I'm aware of in Bucks County is Cooks Creek, located in the very northernmost part of the county. You'll find some wild browns in Cooks, though I've never been able to find more than one access point.
