Upon completion of green drake patterns, my winter fly tying routine normally transitions to pale morning dun imitations. After many years of success I settled on two patterns that generally fulfill my needs during a pale morning dun hatch. Comparaduns represent an accurate low riding likeness, and cinnamon and light gray bodies seem to cover nearly all pale morning dun scenarios. Another variable in the pale morning dun hatch matching game is size, and I typically stock size 18 and size 16 comparaduns, and these two sizes and colors seem to satisfy all my needs.
I collected my fly storage containers and counted my supply of cinnamon and light gray comparaduns in the two prevalent sizes, and I was pleased to determine that I possessed adequate quantities for the upcoming season. This raised the question of why I did not deplete my supply during 2019. The late and heavy run off during 2019 overlapped with the normal hatching time period of pale morning duns on freestone rivers and streams. I sat out the high murky conditions, and consequently missed the bulk of the pale morning dun hatch activity. Another dependable provider of pale morning dun entertainment is the Frying Pan River, but for some reason I never made the trek to the popular tailwater in the Roaring Fork Valley in 2019.
