There are still hatches going on then, but it's a bit early for trico's. Terrestrials will also be working by then.
Browns and Rainbows in the East are not native, but naturalized. There are many waters with self - sustaining populations of Browns and a lesser number with Rainbows. I know of one feeder stream of the LJ that has reproducing Rainbows.
Can't disagree about Donny Beaver. He basically is against free public access to streams, leases access and makes it available to his club members for big bucks. He lost a highly publicized lawsuit over access to the Little J.
The successful Little J access victory and the court mandated removal of the state hatchery that was screwing up Big Spring in Cumberland County were probably the two biggest victories for trout enthusiasts in over 20 years. The problem is that the threats just keep coming. There are things that need to be done to protect access and the fisheries going forward :
I cannot emphasize how much I totally disagree with you regarding stocked trout. Maybe, you guys in central Pa. could get along nicely without them, but here in western Pa., there would be very little trout fishing without stocking. We have a camp in the ANF and even in that heavily forested area, wild trout fishing, with a few exceptions, is limited to small streams and small fish. You would be putting a very high % of the trout fishermen out of business and overcrowd the streams that are left.
When you stock hatchery trout on top of wild trout, there are a mountain of studies that show the population of fish in the stream goes down. Hatchery fish bring disease and stress the existing population. The introduced fish have little chance of surviving for very long. Now, if you're talking about stocking trout in an otherwise fishless stream, that's a different story.
