Most of the high country lakes here in Colorado are clear of ice and the fishing has been outstanding, as usual! Our high elevation waters are absolutely brimming with aquatic bug life...this makes up for the rather short fish growing season. The trout are usually more than eager to eat, but I certainly have some GO TO flies in my box when I am heading for the high ground.
I have chosen three of my favorite high country flies... The Pandemic Callibaetis in either #16 or #14, available at most Colorado fly shops. The Moody Damsel #16 and, for the fly tiers, the DLS Leech available only from your own fly tying desk! Use a TMC 777sp #10 hook, thread on a 5/32" pearl white bead, use dark olive arctic fox fur for the tail and build a dubbing loop using dirty olive Sparkle Leech dubbing for the body. Wrap the dubbing loop up 2/3rds of the hook shank and whip finish, then slide the bead down over the knot. Then build a separate dubbing loop (a short one) to finish the front end of the fly. Use a dubbing brush to comb back the long dubbing fibers.
