What is the possiblility of catching a Yakima resident rainbow measuring 24 inches? I measured a fish of this size for a friend last Saturday. After releasing it, the thought came to me, could it have been a steelhead (technically speaking it was since it was over 20 inches)? As we sat back and contemplated the event, I was sure it was a steelhead whereas he claimed it to be non-anadromous. Granted he is a guide and has seen a thousand Yakima trout where I have only seen several dozen. I know WDFW shocks the river and they find 20+ inch trout. I also know there is a small run of steelhead. The interesting point was the fish was missing the eye on the left side. Another example of how tough fish can be if they get a chance to do their thing. I took some pics before we measured it, assuming it was a large trout as we had caught and released many trout and whitefish before this last fish. We both thought it was around the 20 inch mark and we were surprised to see the results of the tape. Had we, at the time, considered it a steelhead, we wouldn't have taken pics. I currently don't have access to the pics but I wanted to discuss the potential of the Yakima growing 24 inch trout.
