Need help identifying this stonefly. I am located in Northern California, Siskiyou county. We get the salmon fly hatch and the golden stone hatch in the spring time, but this stonefly hatch happens in the fall. This hatch only happens on Burney creek

1ncidentally, Doroneuria baumanni does indeed have a common name, which is Cascades Stone.
However, rather than it having been acquired via the fly fishing community, both it and all other N. American stonefly species known at the time, were assigned common names by an ad hoc group led by Dr. Bill Stark.

Welcome to the forum!
The time of year suggests another possibility. Claassenia sabulosa (Short-winged Stone) is the only perlid well known for hatching in the Fall. The other genera of perlids are usually Spring and Summer emergers. The males have stubby wings well short of their abdomen tips. Even though the females have longer wings, the ones on your specimen (that I believe to be female) seem a little long. Is the anomaly the slightly longer wings or the time of year?
Fortunately, western perlids are relatively easy to identify. This can be done with the naked eye if any spcimens were retained. Check out our encyclopedia for info on how to do this. Are there any closeups of the head, associated male abdominal ventrals or some associated nymph dorsals?

In case anyone is having trouble tracking with the posts in this (somewhat convoluted) thread, for purpose of adult stonefly comparison, the 1st image below is a cropped and slightly lightened version of the 1st photo from Uppersac (Brian Theriot's) id request.
And, the 2nd image below is a cropped version of the 1st photo from RiverKeeper (John Kreft's) wonderful blog, The Golden Stonefly Cousin – Doroneuria baumanni, which was (most helpfully) linked to in Millcreek (Mark Melton's) post.

In order to add an image to an existing post, it must first be uploaded to a server somewhere, like on photobucket, or elsewhere.
Once the photo resides on a server, it's simply a matter of editing an existing post, and then inserting the web address of the image (surrounded by image begin and image end codes) wherever desired in the post.

If you kept the specimen it shouldn't be a problem to ID it. It's a Perlidae species. There are only a few in California. Hesperoperla and Claasenia have anal gills and it doesn't appear that yours does. Doroneuria and Calineuria can be separated by the following features. Doroneuria has the dorsum of body with median, longitudinal row of fine, silky setae. Calineuria does not have the dorsum of body with median, longitudinal row of fine, silky setae.
