Seen some BIG AZZ bear prints down near the mouth while doing the business, makes ya get that job done quickly, I swear they coulda been grizz prints, they were only slightly showing claw though.
I also think a eagle could easily pick off a steelhead and saw one eating a steelhead in another local river, we spooked it off and got pics of the half eaten carcass. In this river and how far up it was it could only have been a eagle or a otter that could have gotten it and possibly a Sasquatch, but they seem to have moved out of this valley lately.
The Vedder fish could easily have been a sport caught mortality with the way they have been holding up in certain areas and probably getting caught a little too often.
