The reason I decided that today's fishing was notable is that it showed a clear lesson on fly selection. The water is still low and clear, and I was fishing The Bridge Pool. There were 3 patterns used. One was a size 14 caddis worm pattern with a chenille body twice the length of the hook shank, 2 wraps of black neck hackle for legs, and a bead head. It was allowed to sink then was retrieved with via figure eight. Two fish took on the fall, three or four took on the retrieve. If the fly was allowed to sink while being followed the fish would loose interest.
The other two patterns were a McPhail Pupa (a very imitative caddis pattern) and a generic light colored Hair's Ear Nymph with crystal flash ribbing.
Which did the fish eat? ONLY the Hair's Ear. You can draw your own conclusions, I have mine. I will say that the biggest take-away is that every fly tying book and fly fishing book I have read (those ones that suggest an impressionistic pattern over an imitative one) is right. At lest in this circumstance.
