1man,
2015-2017 were nothing short of phenomenal. All classes of fish and plenty of larger fish (18+). 2018 was blown out from early spring into early July (I think). It then went crazy high and stayed there into late October. The PFBC did survey showing more fish 18+ surveyed in 2018 than 1997-2017... combined! This spring was blown out again, especially during the spawn. Also coming to light was the sewage releases. Over the last month, it's been low and clear. With the clear water, I'm seeing suckers in normal numbers, catfish in lower numbers, virtually no quillbacks, few carp. In the shallows, lots of small fish. Insect cases in the drift all day long. Turn over rocks and crayfish zoom away. The rocks are filthy with nymphs.
We fish ALL DAY and moving fish is spotty at best. The fish don't seem to be related to structure, weedbeds or islands. Many times, it seems void of fish. The ones caught are in very random spots. You'll occasionally spook a big bass in inches of water but that's about it.
Seems like they are gone until the sun dips and a sporadic hatch starts. A pool that was dead has 50 rising fish! One minute I'd swear something horrible has happened to the river and the next, I feel like they've been here the whole time and refusing to eat. I'm pretty confident that any new PFBC survey will show it's effed up again.
Other baffling things are the abnormal fish behavior. They follow the streamers to the boat several times but won't take the fly. I've also had many fish flee in terror when a small popper lands near structure. That's not like a smallie at all. They normally turn and destroy it without a second thought. I have observed much more normal behavior on the Juniata.
If you can figure it out or explain it, I'm all ears. I have clients going out Sunday. If I see something different, I'll post but I don't have high expectations at this point based on the last 8 weeks of substandard fishing for the Susky.
