If you can find me any species of trout that is native to Missouri and still existing in the waters there, I will concede. There is NO native trout to the midwest. Hell, there are no native rainbows east of Nevada. There are no native Cutthroat outside of the Rockies, and there are no native Brookies west of the Appalachians
I know for a fact that Crane was stocked in the late '60s. Don't think for a moment that they brought trout from the McCloud River multiple times in the 1900s to stock a creek in Missouri. There is no way in hell that these fish are pure, despite what the state wants to claim or insinuate through their trout propaganda.
Beautiful, yes, wild, yes, 100% pure, hell no.
