Fished Waterton on Wednesday....what a great day to be outside!!! I didn?t have much time to bike that far up so I only went a little past the pipeline. It seemed like behind every boulder and at the base of every plunging pool there was a fish ready to hit a prince (my point fly), RS2 (second fly) and especially any type of black midge pattern which I always use as my final fly. I run three flies and they all seemed to get hit fairly regularly. If I had to choose one though, a 22 black beauty is the fly to replace all flies at waterton. Surprisingly decent size fish as well for waterton. Usually I average 8-10 inches but this time I caught a dozen or so around 13 inches. As a final note, right at the base of a canyon I say a guy walking out with a real nice brown of around 20". Unfortunately that brown is probably in some poor shmucks freezer going to waste right now.
