Hello Everyone!

June is off to a killer start as far as fishing goes on the Reef and the Mile. All areas are fishing very well. With the flows being higher on the Reef and Mile, be sure to be a little more cautious when wading; the currents can be stronger than they look. We are starting to see a BWO’s coming off in the mornings along with plenty of midges. We are also starting to see a few PMD’s and Caddis coming off. Rock worms and San Juans are always fishing well including all the popular midge patterns!

  • Midges ( MacGruber, Mayhem) #18-20
  • RS2 #18-20 (Chocolate, Gray)
