I am not sure if the source of my euphoria on Friday, May 9, 2025 stemmed from the continuing outstanding productivity of the olive perdigon or the discovery of a new section of the Arkansas River. With highs in Denver predicted in the seventies, I checked potential fly fishing destinations and settled on the Buena Vista area of the Arkansas River, where the high was forecast to peak in the low sixties. On the previous week I made the drive to the same area, and I enjoyed a very satisfying day of fly fishing, so a return visit appealed to me.

New Water

Every year at this time that spans mid-April until early May, I chase the famed Arkansas River caddis hatch, and that also played into my planning. The fly shop report indicated that the hatch was centered over Salida after the recent cold snap. I surmised that progression to the Buena Vista area was a possibility.

Impressive Start

Love the Spots

I set my Google maps app to a new spot, and I gambled that there was fishing access. The map that I was using suggested that was the case, but there was a risk that I was wasting time seeking out an unknown fishing spot.

Looking Ahead

I arrived at the designated test location by 11AM, and by the time I pulled on my fleece hoodie and raincoat and assembled my Sage R8 four weight and hiked a short distance to the river, it was 11:30PM. I was flying blind, and I had no idea where to park, how far away the river was and what the fishing conditions were like. Fortunately I quickly found the designated parking lot, the walk to the river was short, and the section of the river in front of me looked amazing.

Sole Rainbow

I began my quest for trout with an amber ice dub body chubby Chernobyl, an iron sally and a bright green caddis pupa. I debated using the olive perdigon, but I wanted to experiment with the caddis pupa first. On the first two casts in a deep slot behind a boulder, I hooked and landed two respectable brown trout in the twelve to thirteen inch range; and, needless to say, I was impressed. Between 11:30 and noon, when I found a nice flat rock for my picnic lunch, I added two more browns to my netted fish tally to boost the total to four. Was this for real? All the late morning trout grabbed the iron sally.

Narrow Run Along the Bank Produced

After lunch, however, I endured a brief dry spell, so I reconsidered my offerings and exchanged the heretofore unproductive caddis for the olive perdigon. It was a master stroke. For the remainder of the day the chubby Chernobyl and perdigon were constants in my lineup, and my only change was to swap the iron sally for a go2 bright green caddis pupa midway through the afternoon.

Wide Moderate Depth Riffle Was Prime

Check Out All the Subsurface Rocks

What an afternoon it was! the fish count ballooned from four to thirty-one. In total the chubby Chernobyl accounted for five, the iron sally registered the first four, one fish fell prey to the caddis pupa and the remaining twenty-one hungered for the olive perdigon. I never spotted a caddis fly, but during two extended periods of heavy cloud cover, I noticed a few blue wing olives, but not enough to generate any surface feeding. Apparently there were active baetis nymphs, and the olive perdigon was a close enough representation. Another testament to my good fortune was my ability to fish for three plus hours without losing a fly, and with tungsten beads going for one dollar each, that was good news.

Big Flapper

The river was in prime condition. The flows in Nathrop downstream were around 400 CFS, and crystal clear was the clarity status. I fished upstream along the left bank, and prospected all the deep slots, troughs, pockets and riffles. All these types of structure produced, but the most dependable locations featured the tail end of deep slower moving slots just before the adjoining currents merged and accelerated. A lift at the end of these drifts seemed to be a deadly technique. I love the feeling of confidence, when I lock on to productive flies and identify the most likely fish holding lies. Before casting I could more or less predict the result, although I covered the water thoroughly and produced the occasional nice fish from fairly marginal spots.

Chubby Again

Once again I failed to greet the caddis hatch, but in exchange I discovered a new favorite section of the river, and I reinforced the effectiveness of the perdigon style of fly. I typically dislike tying flies during fishing season, but I may have to deviate from this position, and tie up some more. Other than the expense of the beads, the perdigons are a straightforward tie with minimal materials. A thirty-one fish day is very appreciated, and although the largest probably stretched the tape to thirteen inches, quite a few were in that twelve to thirteen inch range, and all but one outlier rainbow were marvelous vividly colored wild fish. Could I sneak in another day on the Arkansas before the run off thwarts my success? Stay tuned.

As I contemplated options for a day of fly fishing on Friday, May 2, I could not erase thoughts of the Arkansas River caddis hatch from my memory. My young friend, Ben, and I visited lower Bighorn Sheep Canyon on 04/25/2025, and although we had decent success, we did not witness the massive caddis event that we were seeking. We saw two caddis during our entire day on the river. Were we above or below the main emergence, or was the caddis hatch perhaps a non-event in 2025?

Clear Conditions

The cool weather early in the week confined me to short trips to the Front Range, so I was open to a longer drive on Friday. The forecast for Friday was only moderately more favorable with highs in the mid-sixties for Denver. I searched around for possibilities, and I identified the Arkansas River with highs in Salida in the low sixty degree range.

Not a Bad Start

Next I researched the DWR site for flows, and the Nathrop gauge registered 360 CFS. That was encouraging. Finally I visited the fly shop web sites, and the local experts suggested that the main body of the hatch was between Big Bend and Rincon in the Salida area. I like the river structure in the Buena Vista area, and the fly shop reported clear conditions, so I decided to make the drive. Buena Vista is a bit closer than the Salida stretch, and I speculated that perhaps the caddis would advance to Buena Vista, and I would miraculously hit the leading edge of the hatch. One can always hope.

Salivating

I departed on Friday in a westward direction and made the drive on US 285 to the Buena Vista area. When I arrived at my chosen pullout, the air temperature was 53 degrees, and the wind was a very significant factor, and it would remain one throughout my day. Unfortunately it was a headwind, and this played havoc with my upstream casts resulting in significant neck and shoulder fatigue by the end of the day.

Very Respectable

Above the Water

I wore my Brooks long sleeve undershirt and added my fleece hoodie and rain shell. For head gear I wore my billed hat with earflaps, and the choice suited me well, when the wind blasted in my face. I strung my Sage R8 four weight, and I ambled downriver for .25 mile. Along the way I saw a large tent, and this caused me concern that I would be sharing my section of the river with another fisherman or group of fishermen.

Slow Current and Depth Were Key

When I arrived at the edge of the river, I tied a size 8 yellow fat Albert with missing legs to my line. I was using the fat Albert as a strike indicator, so I was not concerned about the missing appendages. Beneath the foam hopper I knotted my 2025 favorite, the olive perdigon, and below that fly I added a bright green sparkle caddis pupa. In the first deep run where I cast, I momentarily hooked up with two fish, but then I persisted and nailed a pair of brown trout, before I found a nice lunch spot. One of the morning browns nabbed the caddis pupa, and the other snatched the perdigon.

On Display

After lunch I continued up the river, until I was just beyond my parking space by 3:30PM, and I boosted the fish count from two to eighteen. By 12:45 I concluded that the caddis pupa was not effective, so I exchanged it for a size 22 sparkle wing RS2, and the fat Albert, olive perdigaon and sparkle wing RS2 remained in place as my offerings for the rest of my time on the river.

Portends Success

Of the eighteen fish landed, one crushed the fat Albert, one grabbed the bright green caddis pupa, and four chased and nipped the sparkle wing. All the remaining trout favored the perdigon, and it was a testament to how effective the simple tungsten bead fly has become to my spring time success. All but one of the trout were browns. The average size of the trout in this section of the river was smaller than that which I experience downstream; however, I did land a couple thirteen inch browns. Most of the other browns and the single rainbow were in the ten to twelve inch range.

Nice One

Surprised by One from the Narrow Space Between Exposed Rocks

What sort of river structure produced trout? By far the best places were deep slots and troughs where currents merged or cushions in front of rocks at the tail of pockets or riffles. I wasted a lot of time fishing marginal spots along the bank, but the fish seemed to place a premium on water depth. I saw only a handful of caddis, so I concluded that the main hatch had not yet reached the Buena Vista area. I did spot a few blue wing olives, but the hatch, if there was one, was very sparse and failed to initiate any surface feeding.

Spots and Colors Superb

I encountered one other angler, and I mounted the steep bank and circled around him. When I approached the tent that I noticed on my inbound trek, I realized that the inhabitant was a gold prospector. We exchanged nods, and he did not seem to care about my presence near his campsite.

Riffle Section

Friday was a fun day, and I was pleased with my destination choice. Did I encounter the famed caddis hatch? No, I did not. Did I experience hot surface action to blue wing olive mayflies? No, that circumstance did not develop as well. In spite of this, I methodically worked my way along the right bank of the river and probed likely spots with my dry/dropper and netted eighteen wild fish. That, in my book, is an enjoyable day, and I beat the onset of snow melt.

Arkansas River 04/25/2025 Photo Album

Last summer I made a couple fishing trips with the grandson of a friend from Bucknell. Ben acquired some used fly rods from a co-worker of his father, and he was very interested in learning the art of fly fishing. Ben turned out to be a quality young man and an avid student of the sport, and I was interested in following his evolution in the world of fly tossing. I contacted Ben’s mother and asked if he had any weekdays, where he was free from school, and she replied with a couple dates. One of them was April 25, so we scheduled a fishing day for that Friday.

I have lived in Colorado for thirty-five years, and each year at this time I make the drive to the Arkansas River in search of the fabled Mothers’ Day caddis hatch. In Colorado the hatch actually commences around tax day and moves up the river at a variable pace, until it ends around Mothers’ Day on the upper river. The hottest fishing occurs at the leading edge of the hatch, as massive quantities of insects emerge, and this event brings the spectacle of hungry fish slashing on the surface. Caddis burst out of their pupa rapidly, and if the wind is strong, they skitter across the surface. Unlike most fly fishing scenarios, drag actually becomes a positive presentation technique. During all my years of chasing this hatch, I hit it two times, where I experienced crazy fishing to caddis adults. It is very difficult to locate the sweet spot, while living 2.5 hours away.

I have, however, on many occasions, arrived at the river in places behind the leading edge of the hatch. These instances are also quite an event to experience. Adult caddis fill the willows and bushes along the river, and a few constantly leave their perch and dap down on the surface for a quick drink. In the morning hours, I have had success picking off a few trout by prospecting the water along the banks with size 16 deer hair caddis. If the conditions are favorable, the caddis leave their roosting spots in the early afternoon and swarm above the river and fall to the water. The trout capitalize on this opportunity, but my fly is one of hundreds, and it takes an extreme amount of luck to fool a trout into taking an artificial over the dense quantity of naturals.

In preparation for a day of fishing with Ben, I researched the 2025 caddis progression. The flows on the Arkansas River were favorable, and clarity was optimal according to the fly shop narratives. The two main fly shops near the river cited hatch activity in Canon City and through lower Bighorn Sheep Canyon as far as Texas Creek. The shop in Salida actually had it extending as far as the Vallie Bridge closer to their shop, of course. These ranges were so broad that they were not very useful in pinpointing the emergence. Finally, I checked the weather reports, and I discovered that Friday was projected to have a high temperature of 54 degrees in Canon City with light rain in the morning and overcast skies all afternoon. These were not the conditions that provide a catalyst to heavy caddis emergence. Caddis like sunny days that warm the river temperature to ideal levels in the mid-fifties.

Baetis, on the other hand, love chilly and overcast conditions. I concluded that I would introduce Ben to the Arkansas River caddis hatch, and the blue wing olives would be a solid fallback. Even if we were unable to find the leading edge of the caddis, he could witness the swarms of the tent-winged adults populating the riverside bushes and rocks.

Ben arrived at my house by 7:30, and we transferred his gear and made the drive. Ben was sporting new stocking foot waders and wading boots, and he was quite excited for a day of fly fishing. We drove through rain, mist and fog, until we exited Canon City, and the low clouds shifted into higher gray masses but lacking descending moisture. During our day on the river the sun barely appeared, and we only felt a light mist a few times.

Already on Its Way

The coolness and dampness prompted me to wear my long sleeved Under Armour undershirt and light down North Face coat with an outer layer of my rain jacket. I snugged on my billed hat with earflaps. I was pleased to have these layers for my entire day on the river. For my fly rod I once again pulled out my Sage One five weight. I was hopeful to need the extra strength of the five weight to handle larger fish.

Center Trough

By 11:00AM we were positioned along the river ready to find hungry and willing trout on the Arkansas River. As we bashed through willows and bushes near the river, I carefully observed in order to assess the status of the caddis hatch in our location. I saw none. Normally the adult flies flush into the air in abundance, when I disturb their habitat, but that was not the case on Friday.

Look at the Load on Ben’s Rod

To begin our day we chose dry/dropper rigs. We both applied chubby Chernboyls as our top flies. Ben added a go2 caddis pupa on a four foot dropper, and I chose an olive perdigon as the top fly and placed a g02 caddis beneath as my bottom nymph. We fished some attractive deep runs, and I managed to hook and land a nice thirteen inch rainbow, while Ben notched a refusal to his chubby.

Brown Trout Success

For the next hour we progressed up the river and shared the left side. I directed Ben to make some longer casts to a shelf pool on the other side of the swift center current, and he executed perfectly. His casting capabilities have advanced admirably since our two outings last summer.

Pocket Water Paradise

By lunch time, noon, we had covered the better water on the bottom of our beginning stretch, so we paused to eat. My initial rainbow trout was the only landed fish in the first hour. After lunch we continued in the same manner as the morning. Given the overcast conditions, I switched the go2 caddis for a sparkle wing RS2 in case the baetis nymphs became active. Ben began changing out flies as well, and at one point he added a sparkle wing RS2 as well as a third fly. Casting three flies is an invitation for tangles, and although he paused to unravel a few, his casting technique avoided the worst.

Covered with Ink Spots

Between 12:30PM and 3:30PM we prospected the most attractive water of the day. The sky remained dark and cloudy, and the wind kicked up from time to time. but we never saw fish rising to blue wing olives. Ben pointed to a pair of small insects at one point, and I identified them as BWOs, but we persisted with our dry/droppers through the sparse hatch.

Deep Slot

Over the course of the afternoon I landed seven additional trout to boost my fish count to eight. All except the first trout were browns, and I gripped a couple in the twelve and thirteen inch range. I estimate that the seven browns were evenly split between the olive perdigon and the RS2. In addition to the netted brown trout, I connected momentarily with four fish that were clearly larger rainbows. In each case the hook held fast long enough to feel the weight, and then the impulsive eaters turned their heads, and my fly catapulted free. I suspect they were on the tiny size 22 RS2 with the small hook gap.

Ben Focused

Ben meanwhile generated many opportunities, but he was unable to slide his net beneath them. I watched him play a very respectable brown trout for a decent amount of time, but when he extended his net to gather the bruiser, the net rim hit the brown, and it splashed downstream to freedom. According to my rules, this counted as a catch, but Ben lives by a stricter code.

I Love This View

In other cases he hooked wild rainbows, and these hot fish streaked about and eventually powered into downstream rapids and broke free. In a few cases the hooks remained, but Ben also broke off three sets of three fly rigs. It had to be frustrating for him, but even so, I was pleased that he encountered numerous opportunities throughout the day.

Late Afternoon Cloud Cover

As we ambled back along the river at 3:30PM, we paused at a long narrow shelf pool next to some fast moving current. As we gazed at the bubble line, we spotted several rises. Ben’s hands were stricken by stiffness, so I tied on one of his chubbies along with a prince nymph and sparkle wing RS2, and I observed, as he worked the seam with expert backhand casts. After quite a few casts, he connected with a fish for a moment, but once again it broke free. In this case I think it broke off the subsurface flies. I replaced them, and he resumed casting, while the rising trout continued to tantalize us with sporadic rises in the bubble line. After a few minutes Ben lifted his flies to make another backhand cast using the current drag to load his rod, and at that very same moment a fish grabbed the chubby Chernobyl. Needless to say the two opposing forces resulted in a another severed monofilament. Ben stated that he is going to purchase a new spool of tippet.

Ben Wading Deep

Friday was a fun day on the Arkansas River. Once again I failed to meet the Arkansas River caddis hatch, and Ben did not see the spectacle, as I had hoped. In fact I saw only one tiny caddis over the course of the day, and then one appeared in my car on the drive back to Denver! We did see some baetis and a few rising fish, but not enough to convert to dry fly fishing. On a positive note, we enjoyed lots of action, and Ben was introduced to fishing a large powerful river. Hopefully I imparted some additional tips and wisdom that he can deploy in his ongoing fly fishing evolution. The weather was as forecast, and we endured, and Ben’s waders did not leak, and he was satisfied with his new gear.

Behind the Boulder

Hopefully we can meet again this summer for some new adventures.
