I know this post is old but thought this may be helpful...May be a cutthroat trout or "cutbow". From my understanding resident rainbow trout have smaller teeth & none on their tongue. Their close cousin the cutthroat have larger teeth & also some wicked smaller teeth on their tongue. Rainbows and cutthroats are often found in the same waters and are capable of & sometimes do interbreed creating hybrids called "cutbows". We have both where i live in the pacific northwest & ive heard of local cutbows but never caught 1 forsure myself. Its always interesting to see the teeth on these guys...the steelhead & king salmon too. During spawning especially the male kings can get some gnarly fangs man!
