There's actually I think four in Venango, 2 of which are in the same watershed. I've only fished 2 of them.
The closest one to Franklin has been on my list for quite a while, but I have yet to fish it although I have fished another stream in the watershed and have caught wilds. That popular one Pennkev is talking about does see it's share of people, but it has fish. The other one is a PITA to fish(brush!!!), and is also mostly private property.
