Current River Flow Updates

Latest update: 6/29/2020 -- 11 Mile canyon is currently at 265 CFS. With the higher flows you can fish bigger flies and tippet. 4x and 4x Fluouro will work great for tandem rigs. Bigger (12-14) Pat's rubberlegs, Stone's, and Hare's ears will give you weight as your first fly. Drop caddis or Baetis off your point fly. Buckskins, Splatte rollers and wired caddis in 18's will do the trick. Make sure you are adjusting your depth and weight until you are in the zone. If you are Euro nymphing use the flies listed above as droppers and add a jigged Rainbow Warrior or your choice of Perdigon as a point fly. Feel free to call the shop for more information on 11 Mile Canyon.
