Hard to see from the pic, but what added to the confusion is that there were only spots on the upper part of the tail. Some of the teeth had white around the base and a couple of them had a little black/gray.Tough call without better photos. First photo is look like the gum line is white where the teeth emerge, second, can't tell. Tail looks Coho. I'm going with Coho. Might make a different call on the river bank.
