That’s what I first thought too. Looks like the strain that is common in some of the CV limestoners. The strain(s) that are established in some of the small freestone streams in NW PA, the Laurel Highlands, and the Upper D watershed look completely different.
That said, the background of that photo suggests a stream that is larger than the CV limestoners. I have a pretty good guess I think, but out of respect for the OP, who chose not to reveal the location, I’ll refrain from posting my guess.
Edit: The below are three wild Bows from three different small freestone streams in PA. For comparison. I don’t have a lot of CV wild Bow pics, as I don’t fish that area often, but maybe someone can post a few of those for comparison.
