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.
Next Step• Based on high EPT values, and• Brock Allen’s sampling from 2007
• Evaluate Upper Reaches and Tributaries Teton River
• Detailed Macro-invertebrate survey• Fish Inventory
Intention to re-introduce/expand Cutthroat Trout
Next Step
• Based on the results for the Dearborn River
