Flows and water temperatures at at ideal levels right now. I was fishing a three fly nymphing rig on a long leader just outside of Lyons. 90% of the fish were taking a size 20 black beauty with a mercury glass bed head in the trailer position. The middle fly was a Copper John alternative tied on a size 12 European scud hood with a tungsten head. The upper fly a was bright green size 16 midge with a white glass head. Nothing large just nice solid browns in the faster deep runs.
