Baetis

Tiny Baetis mayflies are perhaps the most commonly encountered and imitated by anglers on all American trout streams due to their great abundance, widespread distribution, and trout-friendly emergence habits.

I caught this tiny larva without a case, but it seems to key pretty clearly to to Glossosomatidae. From there, the lack of sclerites on the mesonotum points to either Glossosoma or Anagapetus. Although it's difficult to see in a 2D image from the microscope, it's pretty clear in the live 3D view that the pronotum is only excised about 1/3 of its length to accommodate the forecoxa, not 2/3, which points to Glossosoma at Couplet 5 of the Key to Genera of Glossosomatidae Larvae.
27" brown trout, my largest ever. It was the sub-dominant fish in its pool. After this, I hooked the bigger one, but I couldn't land it.

alot of people talk alot of shit about penns not being fishable in the summer
im sure that in the lower sections this is true, however there is alot of canopy covering the creek in upper sections as well as cool under ground springs on some peoples property where the water never exceeds 58
also maybe near the the entrance of elk creek maybe cool aswell but i have never taken a temp reading so i cant verify.
one thing is true, the water is often real low this summer and real clear.

thats interesting, I read about and hear a lot of penns hitting the 80F mark in late summer and I scratch my head and wonder how in the heck trout can survive that, given penns is supposed to be one of the better wild trout streams in pa. I think you said you live near penns so your probably a better source as to what is true and what isnt.

Smallstream,
I would venture to say given the schizophrenic nature of Penns both situtations are possible.
I have been at Poe Paddy when the water temp at 9:00am was already in the mid 70's. This is basically the midsection of the regs and there have been very few cold tribs of any significance for several miles.
From his description IEat is fishing well above Spring Mills which still catches water from subterranean sources so it would be cooler. The same day I took the above temp I was at Coburn 45 minutes later and the water at the confluence with Elk/Pine was solidly 10 degrees cooler.

As for trout survival I have read and heard of trout surviving water temps approaching 80 provided it is thoroughly oxygenated. The problem is any added stress (read fishing) is a guarenteed death sentence. This is where the moral issues of fishing cold water refuges comes in..
