Olive and Tan Caddis Nymphs 10-16, Dark Micro Stones 14-16, BWO Nymphs 18-20, Pheasant Tails 12-18, Hares Ear10-14, Hot Spot Nymphs 10-16, GD Czech Catnip 8-14, San Juan Worms and Eggs would all be good choices right now. Olive, Brown and Black Buggers 6-10 fished deep will produce also. 2-3 strips and a pause is what has been working for me lately. A sinking RIO VersiLeader in the 4-7 ips range or a 200gr sink tip line is the most effective technique for getting down to the fish.
Tan Caddis Nymphs were producing well this week. Water temps are 36-38 degrees on the upper catch and release sections and have remained at 42 degrees on the lower stretches.
