I know this report is a little late but I haven't had the time to post a report.
We hiked up from two pan trailhead to mirror lake on sunday morning. I fished the inlet of mirror lake at first and picked up a dozen or so brookies just on a small caddis fly. Later on in the evening I fished the main lake and picked up a few but none exceded 7 inches.
Next day we hiked to moccassin and I did some fishing off this one penninsula. The lake is surprisingly clear and deep. I used a royal humpy at first and picked up a few 9-10 inch brookies then I thought I would switch to a nymph as the wind picked up but I only had two small strikes on that. So I switched back to a terrestrial and i picked up some more after that.
Later that day we hiked back and picked up camp so we could camp down in the valley. I fished the east fork of the lostine that evening for about an hour and picked up about two dozen fish. That stream is chuck full of fish, you just have to be stealthy.

sorry for no pics of fish, I took a bunch of pictures of the mountains and lakes but totally forgot about the fish. All fish were released unharmed by the way.
