Fly fishing is a science or an art form depending on who you talk to. Many, including myself, will even gladly label it as both. The true pinnacle of both the science and the art is found in match the hatch dry fly fishing. Most good fly anglers have a favorite hatch, especially those who are blessed to reside in a region with rich trout waters supporting a variety of quality hatches to fish.
Many anglers here in east Tennessee have a favorite hatch, but just as many don't want to hem themselves in. This is a product of our relatively infertile mountain streams where a truly memorable blanket hatch is rare although not impossible. Local anglers often gravitate towards generic patterns that resemble of variety of currently hatching bugs. Our hatches tend to be sparse but complex, with sometimes as many as 5 species of mayflies hatching, not to mention the caddis and stoneflies that the fish also love to eat.
I'll never forget the first time I got on a real hatch. Back in 2005 I was blessed to spend time fly fishing in Yellowstone for the first time. I arrived in early June for a week or two of exploring and fishing. My timing could not have been better. The Firehole was just about perfect while the Gibbon was still a tad high but readily fishable.
The first day I headed to the Firehole, I did not really know what to expect. The week or so prior to my trip had been spent tying Blue-winged Olive and Pale Morning Dun Sparkle Duns, two simply elegant flies that still find an honored place in my boxes. I wasn't sure if the hatch would come off, but all of the guide books recommended being prepared for these hatches and the Sparkle Duns were high on the list of accepted patterns for matching the hatches. The Firehole had rising trout in the first place I stopped, somewhere in the first 2-3 miles above the canyon stretch. I quickly tied on a PMD Sparkle Dun and began targeting risers. As it turned out, catching the fish proved relatively easy so long as I could make an accurate cast and prevent drag. That last item was not as easy.
I caught more quality brown trout than is probably fair for anyone to enjoy. At the time, I was thrilled to be catching 8-14 inch browns all day. For that matter, I would still take that kind of fishing now. That trip to Yellowstone quickly fell into an easy routine. Breakfast every morning would be attended by a family of ground squirrels who were hoping for some of the Honey Nut Cheerios I enjoyed. Then it was off for fishing, mostly on the Firehole or Gibbon, but I also explored some of the hike in lakes. Getting spoiled without knowing it, I eventually found it necessary to head for home. Although a piece of me would have preferred to stay in Yellowstone indefinitely, duty called, and I had to get a summer job to help pay for college in the fall.
Arriving back in Tennessee, I soon found myself missing the daily hatches and rising trout on the Firehole. It wasn't until several years later, perhaps four or five, that I enjoyed a great hatch on my home waters in the Smokies. That is not to say that I never experienced hatches or rising trout because I enjoyed both, but a heavy hatch is somewhat unusual around here.
Despite my appreciation for heavy blanket hatches of mayflies, I think I've come to prefer those that are sparse instead of those rare events where the water is covered in bugs. The fish seem to be much more willing to rise to most anything during these hatches we normally experience here in southern Appalachia. That is part of the charm. Each year, my favorite dry fly seems to vary a bit. Some years it will be a Yellow Stimulator in size #14 or #16. Other years it may be a Parachute Adams. This year, I've been on a yellow Parachute Adams kick.
Early on, of course, I stayed with the darker colors of a standard Parachute Adams, sometime switching out for a Spundun or even a tiny Blue-winged Olive Parachute for particularly picky trout. Yes, difficult fish do exist here, but they tend to be easier to figure out than the fish on streams like the Paradise Valley Spring Creeks where anglers have been known to reach madness or the next thing to it while trying to figure out a difficult trout.
Lately, with the transition to the lighter colored bugs of late spring and summer, I kept it a bit more simple than I sometimes do. Instead of elaborate bugs with perfect hair wings and shucks of Zelon, I've kept the Parachute Adams theme going but changed the body color to yellow. The fish approve heartily, but have also rose just as convincingly to a Parachute Sulfur and a Parachute Light Cahill. Like I said, the general idea is more important than the exact bug.
The best days for bugs happen to be the same days that most anglers prefer to not go fishing. Rain or high water keeps the streams open, and if you are adventurous like me, expect some great fishing. Last week, I enjoyed one evening after work where I stood in one spot and caught 8 or 10 fine trout before deciding that it was time to quit. Most were rainbows, but a few of the fish that got away flashed golden brown. One little brown couldn't quite throw the hook before I landed it, but otherwise all the fish were feisty rainbows from 8-11 inches in length. There were just enough natural bugs on the water to get the fish looking up, but not so many that they would miss my imitation as it bobbed downstream in the choppy current. That is a good hatch if you ask me.
