Notes

Troy and I started off on the run a little below the Anderson's bridge. He had a sculpin pattern on and got a vicious hit from a huge fish that promptly broke off the fly after his reel froze and line wrapped around his glove. I fished upstream at the next run and feel in the water after about 1/2 an hour of fishing. My upper body didn't get wet but water ran down to my feet so my feet were numb most of the afternoon. I had no luck nymphing the first run.

We then had lunch and went downstream to a run a little above Indian rock. There were some fishing rising to midges in a back eddy in the foam. Troy started there and I tried nymphing the run with various stonefly and midge nymphs. Nothing. Troy had a couple hits but never hooked anything on the surface. He did a face plant in the water and went back to the truck to change and I rerigged with an olive PME. It was real hard to find my fly among the foam in the backwater, but I ended up catch 3 small rainbows and missing 4 or 5 other fish.

The midge hatch was a gray-bodied midge. The olive PME I used was close but not exact.
