25. Conclusions Each stream had at least one non permissive indicator. Temperature is the leading limitation to re-establishing native fish along the Rocky Mountain Front. The waters are too warm for Bull Trout. None of the stream evaluated has potential to re-introduce Bull, Cutthroat, or Grayling below the sample sites. The upper sections of the Teton River has a native Cutthroat population.
