When I first caught this trout, I thought it was a cuttbow, however, people on fishbrain have been saying it might be a snake river cuttthroat trout. Both of these species are in the dream stream where I caught it so Iím not sure. What do you guys think?
Nice catch! To my eye that looks like a cut-bow. The snake river cutthroats that I've caught had more yellow coloration and a larger spot count. I'm not a biologist though. :) *Attached graphic is from the Wyoming Game and Fish Department
The fine spots are not a dead giveaway. Cutbows and pure rainbows can have awfully fine spots. There are also parasitic organisms that cause fish to be covered in fine black spots...a phenomenon seen often on the Teton River and other high-productivity rivers in the West.
White tips are the only reasonable cue for telling if your fish is a hybrid or not.
All this back-and-forth really doesn't really matter much for the Dream Stream. the OP caught a nice fish, and it matters little if it's a cut, a rainbow, or a cutbow. It's a nice fish that was probably stocked by the CPW a few years back. But it matters a whole hell of a lot on the South Fork and other places where it's important to release the pure cuts and kill the cutbows to maintain breeding populations of pure cuts.
It does matter the original post was asking what people thought and answers were provided. I never had the chance to fish the teton river, however the cutthroats from the snake river were/are Snake River cutts. The fine spots towards the tail are a "dead giveaway" when iding a snake river cutthroat vs yellowstone vs rio grande vs colorado river vs green back. I think there are other factors to consider when comparing a snake river cutthroat to a rainbow, brown, pike, bass, tuna or shark.

Ah, I gotcha BWallace. It appears we were on separate pages of the same book.
Yes, you are 100% correct that the "snake river cutthroat" has finer spots than most other cutthroat species. Interestingly, depending on who you talk to, snake river cutthroat are either considered a separate species from Yellowstone Cutthroat (generally the position of WY fish and game) or are not considered a separate subspecies but rather just a color morph of the yellowstone cutthroat (generally the position of ID fish and Game and the Federal Government).
