Tips and Other Information: The flows are perfect right now!  The fish are feeding hard in the riffles, runs, and pocket water.

The dry fly fishing has been good with pale morning duns, Tricos, and caddis in the slower pools and tailouts.  Crowds are heavy due to its easy access and great fishing this time of year. You can escape some of the crowds by fishing the lower river or targeting the pocket water stretches.

Tips and Other Information: Fishing has been good in Elevenmile Canyon.  Anglers should prepare themselves for a good midge-bite in the a.m. followed by a nice blue-winged olive hatch in the afternoon. Stock your fly boxes with plenty of midge pupa and Baetis nymphs. The fish are moving back into the riffles and feeding hard.  As far as the surface feeders are concerned, its hard to go wrong with a size 24-26 Parachute Adams for the midges and a size 20 Mathew’s Sparkle Dun for imitating the “olives”.
