Current River Flow Updates

Latest update: 11/23/2020-- Flows at 11 Mile Canyon have increased to 117 CFS. Using tungsten bead nymphs with a couple of size BB weights will help you maximize your drifts at these current flows. There are still a few fish looking up, so make sure you have a few small dries in your box. Midge adults, Mole flies, Roy's Emergers, and small parachute adams are all working for dries. Guide's choice hare's ears, BH pheasant tails, Twenty Inchers, or BH prince nymphs are working great for our "weight" flies. Our trailer flies consist of Juju Baetis & BH RS2s in sizes #18-24. At these current flows we will need to be using as light of tippet as possible.
