not sure, and I'm not trying to start a riot, but that looks like a large cutthroat to me. The spots below the lateral line as well as the long maxillary (although obviously damaged) would indicate cutthroat. The photo is from too far away to be sure, and either way a nice fish!
i dont think so will....i blew up the pic and couldnt clearly see the maxillary...i also noticed the worn dorsal and thought hatchery fish....i think it may be a hatchery steelhead with either a half-pounder/estuary life history, or fluvial life history, either of which would account for its size and the spotting...just a guess though.
I am confident that this guy was a steelie, but a naturalized fish from hatchery stock, he had his adipose. I'm no biologist, but over the years I've landed many of these up there. I know the hatchery trucks excess fish into this section every year, and several times at that. These fish just do not have your standard RB qualities. I did get a bigger one last month 6/17/07, will post that pic soon.
