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.

>>The other constant is that you'll find trout and often large trout on feeding stations in spring creeks that you won't find in the freestone streams. You can actually get these trout to rise in the winter even if there is nothing coming off!

There is one major exception to this and that is Yellow Creek in Bedford County. In the fly zone the fish tend to rise even in the winter on this stream for Baetis.... You can usually find rising trout on this stream all winter. I know guys that fish this stream with a little Pheasant Tail nymph or Baetis nymph and just clean up all winter.>>

I don't think that is so much an exception as it is simply another example of the point you were making. I wouldn't consider Yellow Creek a "freestone stream". It's more of a freestone/spring creek hybrid given the geology of its watershed. The same could be said of a pile of other PA streams like the Kishacoquillas, Big Fishing Creek, Penns, the Easton Bushkill, Saucon Creek, Spruce Creek, etc. etc. All of which provide the sort of fishing you describe, and the main reason it is so are the temperature and fertility similarities these waters all share to some extent with those of a "spring creek" as traditionally defined.

Just a viewpoint...

Rlee,
I would classify the current incarnation of the Saucon as a spring creek as it draws 75% or more of it's regular flow from a substantial undergound holding through springs in the more superficial limestone.
The floded mine that feeds the Saucon is approximatly 1.5 miles deep and snakes all over the place. The township which owns that water supply will likely never go dry.

Rleep:

I agree that Yellow is spring fed (and so are the other streams you mention) especially in the upper areas but the way the trout hold feeding stations in the fly area and other parts of the stream is a bit different than how the fish hold a feeding station in a stream like Big Spring.

Also, the volume of water in those streams is mostly dependent upon the rainfall patterns which is not immediately true when it comes to a true spring creek. The volume of water in a true spring creek is extremely stable and depends more on a long term basis over all climatic conditions( such as a drought for 2 years etc.).

The temps on the spring creeks are always the same --usually within 2-3 degrees. The temps. on Yellow and similar streams (especially in the fly zone) can change rapidly.

Also, the turbidity is a factor. Rain seldom bothers most spring creeks but it does change Yellow Creek and other in a hurry some days. The turbidity also plays a factor in fly selection and approach. The spring creeks are alway the same..you know what you are going to get.

I love Yellow and some of those other streams you mentioned. I wish I could get up there more but I'm about 1 hr and 45 mins away. I sometimes leave here and it's 50 degrees in the winter and when I get to Yellow.....it's snowing!

Tight lines and great end of the season fishing...maybe I'll just see you on stream
