You should have some great fishing Feb. There should be Olives and midges hatching at that time. You will also have suckers spawning at the time, although it might be a little early. Anywhere from Benner Springs hatchery north, since the stream flows north. I also like to fish it right up from Bald Eagle Creek. The fish density is lower there but the pressure is much less.
It's a fun stream. For flies I would have Walt's Worms, Many different Sow Bug patters, BWO nymphs and emergers as well as various types of midges.
