If an olive perdigon is effective, why wouldn’t a brown version produce as well? I plan to find out. My salvation nymphs, pheasant tail nymphs, and supernova PMD’s are productive flies throughout the season, but particularly favored during pale morning dun time. It seems to me that a brown perdigon brings a similar size and color to the menu with the added benefit of extra weight to sink the nymph or sink a second fly on the dropper. What about pairing a brown perdigon with a PMD nymph imitation?

Look at the Taper

I get excited thinking about the possibilities. A month or so ago I tied three brown perdigons, but I never introduced them to the Colorado rivers during the fall. While my perdigon hooks and tungsten beads remained out on my tying tabletop, I decided to add seven additional brown perdigons to my storage boxes to bring my total to an even ten for 2026.

A Batch of Seven and Materials

I simply substituted brown thread for olive and brown spade hackle fibers for grizzly. I am now excited to test these flies and my theories on fly attractions.

Olive Perdigon – 11/08/2025

The olive perdigon is a relatively new addition to my fly box, but what a weapon it has become! Two years ago I possessed none, and I just finished building my supply from thirteen to thirty for the 2026 season. How did this happen?

On 10/03/2023 my friend, Dave G., invited me to join him on a private stretch of the Eagle River. Within the first hour, Dave G. was landing nice fish after nice fish, and I managed a couple dinks. I asked to borrow one of his productive flies, and it happened to be an olive perdigon with a tungsten copper-colored bead. My fortunes reversed, and I experienced a twelve fish day that included some very respectable fish.

Fast forward to the spring of 2025, and for some reason I began to experiment with the olive perdigon. I tied around ten of them over the winter of 2024-2025, and I was amazed with their productivity in the early season. They produced quantities of fish on all the Colorado rivers that I visited prior to run off. Their fish catching ability faded a bit in the post run off time frame, but when I returned to the large river valleys in the fall, their effectiveness resumed.

Side View

I attribute much of their success to the tungsten bead, I theorize that the very dense bead sinks the fly rapidly to the bottom of the river and provides a longer drift within the feeding range of the trout. When I combine it with another nymph in a three fly dry/dropper, it also sinks the paired nymph to the eye level of the trout. Although the density of the nymph is a positive for achieving long deep drifts, it also offers the disadvantage of snagging more frequently, and consequently I lost quite a few flies. The beads are quite a bit more expensive than the typical brass bead, so each lost fly is mourned by this frugal angler. The loss of flies forced me to approach my vise to tie additional perdigons during the fishing season; a task I normally try to avoid.

Opposite Side

The olive perdigon has climbed from absent to a top five mainstay in my fly box. I tie an olive perdigon to my line more frequently than my revered hares ear nymphs and salvation nymphs, so that is saying something. Given this new status as the top dog of my fly inventory, I kicked off my fly tying season yesterday by augmenting my olive perdigon supply. I counted thirteen among my fly boxes, and I decided to target a starting inventory of thirty. I can report that seventeen flies were added to my count.

Although more expensive than most nymphs due to the cost of the tungsten bead, these flies are relatively straightforward to tie. All that is required is a copper colored slotted tungsten bead, a jig hook, medium olive thread, spade hackles from a rooster neck, a black permanent marker, and UV resin and lamp.

Thread, Feather and Finished Product

Place the bead on the hook with the slot facing upward and toward the rear. Start your thread behind the bead and make tight wraps to lock the bead in place on the angled portion of the jig hook. Wrap the thread to the rear and then wrap forward to one hook eye behind the bead. Tie in six barbules from the grizzly feather to form a tail approximately three-fourths of the length of the hook shank and then wrap the thread to the bend. Wrap the thread forward to the bead and snip off the ends of the hackle. Now repeatedly wrap the thread to the rear and back to the bead to form a nice tapered body. Once you create the taper that flows nicely into the bead without leaving a gap, whip finish and cut off the thread. Grab your permanent black marker and carefully place a black spot on top of the body, where it meets the bead and then on the top of the bead. Get out your UV resin and apply a coat to the point where the bead meets the body of the fly and then coat and cover the entire thread body. Try to make the UV resin at the junction a bit thicker than the body coat. Fire up your lamp and cure the resin. You now have a new sleek olive perdigon.

Hopefully thirty will suffice for the 2026 season. If not, it probably means that the olive perdigon demanded a lot of time on my line, and running out and having to tie more in season is a good problem to have.

 

 

Big Thompson River – 11/04/2025

Time: 12:00PM – 2:30PM

Location: Canyon downstream from Estes Dam

A forecast high of 77 degrees in Denver prompted me to complete a last gasp fly fishing excursion. I was not interested in a long drive, so I considered Clear Creek, South Boulder Creek and the Big Thompson River. According to my weather sources, highs of 62 were expected at all three spots. My intuition suggested that I should visit South Boulder Creek; however, I was averse to making the one mile hike to and from the creek, so I settled on the Big Thompson instead. Spoiler alert. It was a lackluster day.

I arrived at a pullout by 10:45AM, and I quickly prepared for a day on the river. The flows were tumbling along at 25 CFS, and the stream was low and clear, but it looked promising nonetheless. The dashboard temperature was 56 degrees, so I slipped on my fleece hoodie and assembled my Loomis two piece five weight. I like the slower action of the Loomis, and I expected to toss a dry/dropper most of the day.

I crossed the highway and found a fairly friendly route to the river, and then I knotted a Jake’s gulp beetle to my line. The beetle produced well on my last trip to South Boulder Creek, so I was anticipating a repeat on a different Front Range stream.

I completed two desultory casts, and then I decided to move to more attractive pools, but when I stepped with my left boot, it slipped and shot backward. I tipped forward and stopped my fall by bracing with my right hand, but it was not before a small amount of water spilled over the top of my waders. I felt the dreaded trickle down both legs, and then the wetness, as my right sock absorbed liquid. What now? I was wet and chilled, and I barely began to fish.

Had it been the summer, I would have fished on, but I was concerned about the cooler temperatures of autumn, so I scaled the bank and returned to the car. First I removed my fleece hoodie with a drenched right sleeve. Next I removed my undershirt and replaced it with a long sleeve version. I pulled off my waders and turned them inside out and placed them on the hood of the Telluride to dry in the sun. I removed my long underwear and socks and pulled on a dry pair of each. I wanted to provide adequate time for the inside of the waders to dry, so I ate my lunch early, and sure enough, after eating, the neoprene booties were dry, and I pulled them on and resumed my fishing. The sleeve of my fishing shirt was a bit wet, and the front pack was also showing the effects of being submerged, so I pulled on my raincoat to guard against additional soaking from the front pack.

Glare and Shadows Were a Challenge

I wish I could say it was worth it. I began fishing in earnest at noon and continued until 2:30, The beetle was ineffective, so I removed it and replaced it with a peacock hippie stomper and then added an olive perdigon on a two foot dropper. The perdigon registered two small trout barely beyond my six inch minimum for counting. I covered quite a bit of stream real estate to log two small fish, so I added a beadhead hares ear nymph hoping that it would extend the depth of the drift and attract more action.

Small Jewel

The move worked somewhat, as I raised the fish count from two to six by the time I quit at 2:30. The four additional trout were only slightly longer with the biggest extending to eight inches. It was a lot of casting for minimal return. I moved back and forth between the two banks, and the shade and sun glare were alternating hindrances to catching fish. Deep pools were not productive, although I continually attempted to cash in on their appeal.

Productive Spot

I fished around a large bend in the stream and continued into a canyon stretch. I was hoping that the canyon was not as easily accessed by anglers, as it required more rock hopping  and difficult wading, and I did manage to land four small trout, but it was not close to the unpressured bonanza that I envisioned. On the day, three of the landed fish were brown trout and three were rainbows. In the last hour I connected with two or three fish that felt slightly larger, when the flies began to swing at the tail of the run or pool, but in every case I only felt the weight of the fish for an instant.

Foam Pool

Tuesday was a bonus day for this fair weather angler, but it probably convinced we to refocus my efforts on stocking my fly boxes for 2026.
