South Platte River – 05/24/2025

Time: 10:30AM – 3:30PM

Location: Eleven Mile Canyon

South Platte River 05/24/2025 Photo Album

As I mentioned in my post of 05/20/2025, I was set to visit the South Platte River, when I was distracted by the temporary low flows on the Arkansas River and made that my destination on Monday. Friday was my day to follow through on my initial inclination. I made the trip to the South Platte River in Eleven Mile Canyon. The high temperature was projected to reach the low seventies in nearby Lake George, CO, and the flows were actually running a bit low at 58 CFS.

Looking Ahead

For this trip to Eleven Mile I decided to experiment with a new stretch of the river. I usually frequent the upper special regulation section below the dam, but I admire the open water area, as I drive by. Sure, the bait fishermen are able to ply the river with their offerings, but I have learned historically on other streams that wily fish remain that are able to avoid the drifting worms and power bait. The key is to probe out of the way and difficult to reach spots, and these types of water exist in abundant quantity in Eleven Mile Canyon.

Number Two

Typical Productive Water

I slowly drove up the canyon while scanning the river for faster sections, until I finally found an area that exhibited the characteristics that I was seeking. The temperature was in the low sixties, so I pulled on my rain jacket for extra warmth, and I rigged my Sage R8 four weight. By 10:30AM I was on the river, and I began my angling day with a size 8 tan-body pool toy hopper, an orange scud and an olive perdigon. Between 10:30AM and 11:45AM I prospected all the likely seams, slots, pockets and riffles; and I notched four trout in my fish count. Two were rainbows and two were brown trout. One aggressive rainbow crushed the pool toy hopper, and the others grabbed  the nymphs. After twenty minutes the orange scud failed to deliver, so I substituted a beadhead hares ear nymph, and it attracted one rainbow, while the other two trout favored the olive perdigon.

Did the Job

Colorful Rainbow

After lunch on a nice flat rock, I continued up the river, and I built the fish count to seven. The three additional trout chose the hares ear, and in the process of landing one of the nicer rainbows, the olive perdigon broke off. I always grieve the loss of a perdigon, and the expensive tungsten bead, and I did not wish to expose more to that risk, and the trout seemed to like the hares ear, so I dipped into my fleece wallet for a PMD supernova to replace the perdigon.

Pocket Water Delight

By one o’clock I encountered a group of elementary age kids splashing and playing on a huge exposed boulder in the middle of the river. The river in the upstream area was wide and shallow and slow moving, so I retreated to the car and advanced up the road for .2 mile. I parked and jumped into another narrow section that contained deep pockets, plunge pools and exposed boulders. This was exactly the type of structure that I was seeking.

Seams Always Good

For the remainder of my afternoon I probed the likely spots, and I increased the fish count from seven to seventeen. Two nice brown trout in the fourteen inch range graced my net during this phase of my day. Both of the large trout emerged from lies in front of large exposed boulders, where the current deflected off the upstream face. Part way through the afternoon time frame, the PMD supernova was separated from my tippet, and I replaced it with a salvation nymph. Of the ten trout landed, as I moved the fish count from seven to seventeen, two consumed the supernova, one mauled the pool toy, one nabbed the salvation nymph and the remainder picked off the hares ear.

One of the Better Fish

Emerged from the Current Seam

My theory held. The section featured fast water with pockets and slots and hidden seams, and I used my dry/dropper to probe each possibility. Most fishermen prefer the deep pools and the entering runs as obvious fish magnets, and I avoided these spots that are normally pressured by the bait dunkers. I would not characterize the fishing as sizzling, but rather steady. Not all promising locations yielded results, but if I moved at a steady pace and persisted, I was able to create adequate action.

Covered in Spots

Nice Brown from in Front of the Large Boulder

Aside from the two fourteen inch browns, I netted quite a few trout in the eleven to twelve inch range, and I recalled at least four decent fish that shed my fly hook after brief fights. On the day I estimate that the ratio of browns to rainbows was roughly 50/50.  Overall it was a fun day. I always enjoy discovering new streams or different sections of rivers that produce favorable results. I will definitely do more exploration of Eleven Mile Canyon.

Arkansas River – 05/20/2025

Time: 11:30AM – 3:30PM

Location: Near Buena Vista

Arkansas River 05/20/2025 Photo Album

As I waded through my options for fishing on Friday, May 16, 2025; I reviewed the flows on the various Front Range streams. This survey of the DWR flow data taught me that the South Platte River was the one remaining moving water alternative, and I decided Eleven Mile Canyon would be my choice on Tuesday, May 20, 2025. However, after a series of cool weather days, I checked the stream conditions on the Arkansas River at Nathrop, and I was surprised to learn flows dropped from the 800 CFS range to the low 500’s. Could I squeeze in one more day on the Arkansas, before it blew up again, when run off resumed? I called the fly shop in Buena Vista, and Thomas answered and told me that the river was indeed clear and dropping and a viable fishing option.

I succumbed to the allure of the new area of the Arkanasas River, and made the drive to Buena Vista. Along my route I saw digital signs warning of the danger of high wind. Was my decision to fish in severe weather conditions a good one?

Flows Were Up a Bit but Decent

I stopped at the Buena Vista fly shop and introduced myself to Thomas and purchased a spool of 4X tippet and continued on my way to the parking area near my chosen fly fishing location. The temperature, when I exited the Telluride was 56 degrees, but the wind was gusting and made it feel much chillier, so I pulled on my long sleeve thermal undershirt, my fleece hoodie and my North Face light down coat. I forgot to pack my rain shell, which I normally use as a windbreaker. I also decided against wearing my wide brimmed western hat in favor of my billed New Zealand hat with ear flaps. This may sound like overkill for 56 degrees, but I was comfortable for most of the morning and early afternoon. For a fly rod I pulled my Sage One five weight from its tube to combat the wind.

More Clear Pockets

I hiked the .15 mile path to the top of the bank overlooking the river, and then I followed the trail downstream for .2 mile, before I negotiated the bank and positioned myself along the river’s edge. I wanted to explore the downstream area, since I did not start there on my earlier trip. To begin my search for trout, I selected an amber ice dub body size 8 chubby Chernobyl, and then I added an iron Sally and an olive perdigon.

A Winner

The river was a bit higher than my earlier visit, and this forced me to limit my casting to the west bank with minimal coverage of the center of the river. I prospected for thirty minutes until lunch at noon, and I managed to land three brown trout. Much to my amazement one crushed the chubby Chernobyl and the others grabbed the olive perdigon.

In Front of the Boulder Produced

After lunch I resumed my progress, and my success was limited to a couple temporary hookups. It was at this time that I waded to a spot, and when I placed my right foot between two rocks, it slipped causing me to temporarily lose my balance. My rod was in my right hand, and I reached down with that hand to prevent a fall, but I also placed the rod across two exposed rocks. Although I did not fall, I did suddenly lean to the right to rebalance, and this act snapped the Sage One in the butt section. Needless to say I was not happy, but after a bit of berating myself for my stupidity, I regained my composure. I removed the flies, broke down the rod, and returned to the car; which, fortunately was not far away. I returned the broken rod to its case and pulled out my back up five weight Loomis.

Promising

I returned to the river and resumed from the scene of my unfortunate accident. I exchanged the iron sally for a 20 incher and maintained the perdigon. These flies remained in place, until I snagged something in front of a large exposed rock, and the location was too precarious to allow a rescue, so I ended up snapping off all three flies. When I rigged anew, I substituted an olive-black Pat’s rubber leg for the 20 incher.

Chubby Eater

Using these fly combinations I increased the fish count from three to eight, before I called it a day around 3:30PM. The chubby Chernobyl accounted for two fish, the rubber legs logged one, and the remainder nabbed the olive perdigon. My day was rather slow, and I covered a lot of water to generate the eight fish day. The wind was a huge hassle. It gusted frequently from the north and created a frustrating headwind. My most effective casts were up and across with long drifts across from my position and downstream. Most of the landed fish appeared from deep lies in front of or next to large submerged or exposed boulders. I suspect that the lack of insect activity and the cold snow melt caused the fish to hug structure and not move very far for food.

One of the Better Fish

The size of the fish was quite favorable with nearly all being in the twelve to thirteen inch range. In one place I made a cast across a fast current to a wide slow moving pool below a large boulder, and as the flies began to swing, a fish grabbed one of the nymphs. I set the hook and turned the fish temporarily and exposed the side of a fairly long brown trout. I suspect it may have been the largest fish I’ve seen in my newly discovered stretch of the river.

Lovely Spot

I suspect I should have adhered to my original inclination and fished the South Platte, but high winds were in the forecast there as well. Breaking my rod was a bummer, but landing eight nice brown trout under challenging conditions during a lull in run off was actually a decent accomplishment  Nevertheless, tailwaters and lakes are in my future.

Pine Valley Ranch Lake – 05/16/2025

Pine Valley Ranch Lake 08/16/2025 Photo Album

After experiencing a skunking on Wednesday and enduring a continuing struggle with a cold, I considered my options for a day of fly fishing on Friday, May 16, 2025. My Tuesday outing involved a long drive to the South Platte River, so I filtered my choices to those close to Denver. I examined the DWR flow information, and I quickly discovered that all the Front Range streams were in the process of blowing out with rapid increases in volume. Even South Boulder Creek, a tailwater, was chugging along at 199 CFS.

The one drainage that was conspicuous as an example of favorable flows was the South Platte River tailwaters. Other than the Waterton Canyon stretch, however, they all involved relatively lengthy drives, and I was reluctant to undertake that, having made the trip on Tuesday to Eleven Mile Canyon.

I shifted my attention to lakes, and in a short amount of time, I settled on Pine Valley Ranch Lake. The travel time was reasonable, and I love the Pine Valley Ranch Park, and I enjoyed decent success at the lake in prior seasons. The stocking report indicated that a transfer of trout took place on March 28, and that was quite a while ago, but I gambled that hungry fish remained albeit perhaps a bit wiser and more spread out.

In the meantime, I received a text from the mother of my fly fishing student, Ben, and Ben had Friday off, so I invited him to join me. He jumped on the opportunity, and I picked him up at 9:30AM, and we continued our drive out US 285 from there. We arrived at the lower parking lot by 10:30AM, and six other cars were present. A fisherman was preparing to fish in one of the vehicles, but the others seemed to be hikers and dog walkers.

I wore my down coat and my rain jacket, and I fit together my four piece Sage R8 four weight. Ben assembled his gear and rods, and we hiked around the lake to a spot on the south shoreline. I selected the long way around to familiarize Ben with the surroundings, since it was his first visit.

Ben’s Early Catch

Initially I fished a peacock hippie stomper, salvation nymph and salad spinner midge pupa, and I managed one connection. The rainbow leaped from the water several times and then shed the hook, before I could gain control. Ben, meanwhile, was fishing with a balanced leech streamer that displayed shiny brown fibers and a tungsten bead. His choice proved fortuitous, as he hooked and landed three rainbows of above average size in the time period prior to lunch. In addition, he noted some follows and recorded a few temporary hook ups, so his action was quite impressive.

Ben with Fish Number One

We paused for lunch at noon, and after lunch we resumed our efforts to attract the attention of the lake dwellers. After seeing Ben’s success, I removed my dry/dropper setup, and I knotted a woolly bugger to my line and crimped a split shot right above the eye of the hook. The bugger had a brown marabou tail and a peacock chenille body. The wind was gusting dramatically, and this in turn caused small waves to develop on the surface, and I assumed the fish were unable to see the hippie stomper. The woolly bugger failed to produce, so after fifteen minutes and many casts and strips, I replaced it with the streamer I made, while my grandson, Theo, observed.

Intruder

Theo Thunder

Imagine my excitement, when I felt the bump of a take and hooked and stripped in a slightly above average-sized rainbow trout. I simply threw together a jumble of leftover materials for this fly, so It was very gratifying to achieve success.

Streamer Stripping

The weather went through cycles that consisted of strong wind, waves, and clouds; and then sunny and clear skies. During the sunny periods, the surface would change into smoothness, and then a smaller cloud would block the sun and create an overcast and a bit of riffle, and the lake would bloom with sporadic rises. Between one and two o’clock, when we quit, I settled on the double dry approach with a peacock hippie stomper and a size 22 dry fly. The fly consisted of a light olive quill body and olive wing and dubbing at the thorax. I noticed a few small adult midges buzzing about, and they appeared to display the same light olive coloration.

Not Bad for Dave

Finally I enjoyed some success. I landed three rainbow trout, and two sipped the small olive dry fly, and one crushed the hippie stomper. All these fish hit the surface fly, after I cast and waited for twenty to thirty seconds. Stripping and popping the flies was not an effective technique on this day. Also, the fish responded during those times, when the sky clouded and before the wind became too strong.

Ben’s afternoon was quite slow after a solid morning, and we agreed to depart at 2PM. Four trout in three hours of fishing was not impressive, but I had fun introducing Ben to a new spot, and I was thrilled to observe his streamer success. I look forward to more lake fishing over the next several months.

St. Vrain Creek – 05/14/2025

Leave a reply

Time: 11:00AM – 11:45AM, 1:00PM – 2:00PM

Location: Near Lyons, CO

This story begins with the Mothers Day hike that Jane and I completed in the Wild Basin area of Rocky Mountain National Park on Sunday, May 11. During our drive to the park, we traveled along the South Fork of St. Vrain Creek, and it looked fishable even though run off was commencing on many Colorado freestone streams after hot days over the weekend.

With nice weather once again in the forecast for Wednesday, May 14, I considered my options and decided to attempt to sneak in a freestone day on the South Fork, before snow melt became a permanent condition. I arrived at a pullout along CO 7, and the thermometer displayed 61 degrees, so I wore my fishing shirt with no additional layers. I assembled my old Sage four weight, and I followed a path down a gravel bank to the creek and then bashed through some bushes to the end of a nice pool with a center-cut run. I knotted the amber ice dub size 8 chubby Chernobyl to my line that served me well on Tuesday, although it was now devoid of legs on one side. Beneath the chubby I added a weighted 20 incher and then an olive perdigon. The creek was clearly in the early stages of run off, but the water was crystal clear, so I hoped that I could extract some trout with my heavy dry/dropper rig.

Well, that theory failed to materialize. Between 11:00AM and 11:45AM, I worked my way upstream and drifted the offerings through every spot where the current slowed enough to enable fish to hold. No dice. I never saw a refusal or a look or even a darting fish escaping my wading. Either the creek contained no fish, or the early stages of run off forced the stream inhabitants to hug the banks with a case of lockjaw, as they adjusted to new conditions.

I cut my losses and moved on to the North Fork of St. Vrain Creek at Buttonrock Preserve. I found a parking spot at the trailhead and quickly downed my lunch in the car. By now the wind was gusting, although the temperature was around 66 degrees. My gear was already at the ready from my previous stop, so I hiked up the dirt road for a ways, and resumed my quest for St. Vrain trout.

Apparently catching fish was not in my future for Wednesday, May 14, 2025. I spent an hour on the creek probing likely holding locations for trout. The hour proved to be a heavy dose of futility. For the first thirty minutes I kept the chubby in place, but eventually I swapped it for a peacock hippie stomper. For nymphs I cycled through the hares ear nymph, olive perdigon, emerald caddis pupa, and a PMD supernova. None of these offerings attracted fish, and similar to the earlier stop on the South Fork, I never observed a fish. I did not sight a fish, I witnessed no refusals or looks, and no fish darted for cover, as I advanced upstream. I have had terrible luck on trips to the North Fork, and I am removing it from consideration for future trips.

As I typed this report, I checked the flows, and they have increased from 51 CFS to 99 CFS over a less than 48 hour period. Perhaps the fish were hunkered down attempting to adjust to the significant shift in flows. For now, I will accept that explanation, but it doesn’t change my avoidance of the Buttonrock Preserve for the near future.

South Platte River – 05/13/2025

Time: 11:00AM – 4:00PM

Location: Eleven Mile Canyon

South Platte River 05/13/2025 Photo Album

After a fantastic day on a new section of the Arkansas River on Friday, I yearned to return. However, temperatures in the upper eighties over the weekend spurred a heightened amount of snow melt, and when I checked the streamflows at the Nathrop station on Monday, the graph depicted a severe slope upward. I called the local fly shop, and Tony informed me that the fishing on the Arkansas River was probably on hold, until the run off began to subside in June. It was time for plan B.

Zoomed

I quickly shifted gears and examined the flows on tailwaters starting with Eleven Mile Canyon. I knew from previous years that the water managers hold back water to fill the South Platte reservoirs, and that proved to be the case in 2025. The gauge at Lake George was displaying flows in the mid-eighties, and I recognized this as an opportunity to visit Eleven Mile Canyon.

Produced

Behind the Boulder

I arrived at one of my favorite parking lots at 10:30AM, and the temperature registered 61 degrees, and the sky was quite overcast. I opted for my raincoat as my only layer, and I pulled together my Sage R8 four weight. I love this rod on medium sized rivers. To begin my effort to net South Platte River trout, I knotted an amber ice dub size 8 chubby Chernobyl to my line, and then, being in a contrarian mood, I selected a partridge and orange wet fly and a hares ear nymph. I wish I could report that my choice of a seldom used fly paid dividends, but after fifteen minutes of casting in relatively attractive water, I had nothing to show for my experimentation with a classic wet fly and nymph. I moved the hares ear to the upper position and replaced the partridge and orange with an emerald caddis pupa.

Love the Pose

After this change in plan, I began to catch a few trout on the hares ear, and I steadily progressed upstream. When I rounded the bend, I was disappointed to spy another angler, and a second person stood nearby next to a folding chair. This clearly blocked my forward progress, but I advanced, until I was twenty yards below the man’s position. I later discovered that the other person was the angler’s wife or partner. During this period, I increased the fish count to six, with the hares ear doing most of the damage, although after a short trial, I abandoned the caddis pupa and replaced it with the trusty olive perdigon.

Right Side Slick

Upon approaching the couple, I exited right and circled around them through a dense clump of bushes and then followed the road, until I arrived at a spot, where the river ran right next to the dirt lane. Another angler arrived in the meantime, so I moved another twenty yards upstream and continued my upstream progression. I found a nice clear spot along the bank and chowed down on my lunch before resuming.

Just Before Release

For the most of the remainder of the afternoon, I persisted with the chubby Chernobyl, hares ear nymph, and olive perdigon. By 3PM, I spotted some stray blue wing olives, so I replaced the hares ear with a PMD supernova and then a sparkle wing RS2. Each of these flies yielded a pair of fish.

Very Respectable

After lunch I moved through some pocket water and then made some long casts in the smooth pool and glide at the bend. I did connect briefly with what felt like a heavier fish, as it attacked the chubby Chernobyl at the tail of the long slick. Once I passed the run and pool, I debated whether to move to my second favorite location, but I decided to persist. The next section featured a wide area that spilled around exposed rocks, and this created pockets, albeit relatively shallow. The gambit paid off, as I built the fish count to twelve, and this included some surprising twelve inch brown trout from fairly marginal lies.

Spectacular Spots

Once I covered the pockets, I opted to exit, since another slow moving deep pool was in my future. I hiked back to the car, and the couple that I encountered was present at their vehicle next to mine, and the gentleman was using the folding chair to remove his waders. We shared greetings and a brief exchange of our successes, and then I departed and moved .3 mile up the river to my next area to explore.

Shelf Pool

Rare Double

I spent the rest of the afternoon prospecting pockets, slots and deep runs among faster water, and I advanced the fish count from twelve to twenty. Among these catches were a pair of very nice and chunky thirteen inch brown trout. In addition, I experienced a rarity, when I hooked two fish at once and landed them both. A nice thirteen inch brown trout grabbed the chubby, and as I began playing it, a small brown nabbed one of the trailing nymphs. This always makes me wonder, whether I need to strip my flies faster, since the fish nailed the trailing nymph, while the larger fish streaked about attempting to escape.

Source of Double

My big revelation on the day was the effectiveness of the juicy chubby Chernobyl. Six of the twenty netted trout mashed the chubby, and these were some of the larger trout. The hares ear accounted for three, the supernova added two, the sparkle wing tallied two and the remainder grabbed the olive perdigon. The perdigon was a factor, but it was not the heavy lifter that it has been in recent outings.

Covered in Spots

Although Tuesday was a solid day, I would not characterize it as hot fishing. I covered a huge amount of the river and made an abundant quantity of casts. Places that I was certain would produce failed to do so, and other spots that screamed marginal came through. Tuesday’s success required a lot of casting and steady movement and above all continued focus. Hopefully I can squeeze in more stream fly fishing, before I am forced to resort to stillwaters.

Surprisingly Productive Chubby Chernobyl

Arkansas River – 05/09/2025

Time: 11:30AM – 3:00PM

Location: Buena Vista Area

Arkansas River 05/09/2025 Photo Album

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.

South Boulder Creek – 05/04/2025

Time: 11:15AM – 3:00PM

Location: Below Gross Reservoir

South Boulder Creek 05/04/2025 Photo Album

I normally avoid fly fishing on weekends, but on Sunday, May 4, 2025 I made an exception. The weather forecast for Monday through Wednesday of the upcoming week portended adverse fishing conditions, so I made the trip to South Boulder Creek. I kept my eye on the flows below Gross Reservoir, and they remained steady at 45 CFS for more than a week. These flows are a bit low for my preference; however, I have enjoyed success at even lower levels. The high temperature in the canyon was forecast to reach the mid-sixties, so that also played into my decision.

By the time I made the relatively short drive and jumped into my gear and hiked to the creek, my watch displayed 11:15AM. My trip through Flagstaff Mountain Park was slowed by a caravan of cyclists climbing the steep and winding road. Kudos to all the riders who finished the ascent.

Covered in Spots

The parking lot at the Walker Ranch Loop Trailhead was nearly full, but I lucked out and found a recently vacated slot. I wore my fleece hoodie, but I avoided my long sleeve undershirt and stuffed my raincoat in my backpack. The temperature at the parking lot was 61 degrees. I have been using Pinecliffe, CO in Weather Underground as my proxy for weather at South Boulder Creek, but I concluded that the higher elevation mountain village probably understates the air temperatures in South Boulder Creek below Gross Reservoir.

Narrow Ribbon of Fishable Water

To begin my quest for trout I began with a peacock size 14 hippie stomper and then added an olive perdigon on a three foot dropper. Beneath the perdigon I knotted a size 20 salad spinner midge pupa imitation, and I began to probe the likely fish holding lies. In a short amount of time I landed a small brown trout barely longer than my six inch minimum, and it grabbed the perdigon.

Stripe Separate from Cheek

As I began my move to the next attractive spot, I noticed two anglers not more than thirty yards above me. I did not pass another fisherman during my entire inbound hike, yet two competitors showed up within a stones throw of my position! Needless to say I was disappointed, so I stripped in my line and secured it and circled around the invaders of my sacred space.

A Brown Joins the Fun

I hiked .25 mile to give them space, and then I angled back to the creek in a place where I enjoyed decent success in the past. I once again began to probe the pockets, runs and riffles; and I added three rainbows to bring my fish count to four by lunch time a bit before noon. During this time I abandoned the salad spinner and replaced it with a beadhead hares ear nymph and a bright green caddis pupa, but all the action came on the olive perdigon and hippie stomper.  I quickly munched my sandwich and carrots, and then I resumed my prospecting, but guess who I spotted thirty yards above me? It was my nemeses. I saw one of them look back, and they spotted me, so they quickly moved out of sight. I made a mental note of where they were first noticed, and then I fished to that spot and pondered my next move.

Nice Bankside Run

I suspected that they exited and left the next stretch undisturbed, but I could not be sure, so I once again cut over to the trail and worked my way up the path. I found them just downstream of my favorite pool, so I stealthily bypassed them and hoofed quite a distance before re-entering the creek. I estimate that I hiked at least half a mile to allow them space.

As I recall, the fish count was now at six, and during the remaining time on the water, I elevated it to seventeen. The hares ear and caddis pupa failed to generate any action, so I replaced them with a sparkle wing RS2, and I kept the hippie stomper, perdigon, RS2 combination in place for quite a while.

Scene of Rising Fish

At 2PM I approached a gorgeous long pool with a deep run flowing down the center. Just before arriving, I experienced quite a few refusals to the hippie stomper, so I decided to remove the nymphs and transition to a double dry with the hippie stomper and a size 16 olive-brown body deer hair caddis. The caddis fooled one fish, before it created some refusals, and I began to spot a few random rises. My hunch told me that blue wing olives were emerging, so I replaced the caddis with a CDC blue wing olive.

Brilliant

I persisted with the double dry for the next hour, and I added four more trout to bring the total to seventeen. For some reason the stream residents began to smack the hippie stomper, when it was combined with the tiny CDC BWO.

The Workhorse Fly on Sunday

By 3PM I once again bumped up against a trio of anglers, so I decided to call it a day, and I completed the arduous one mile steep ascent from the creek back to the parking lot. The weather was perfect, and I landed seventeen fish, so I cannot complain. Nevertheless, the size of the trout was lacking, with the largest perhaps in the eleven inch range. Oddly the ratio favored rainbows with probably seventy percent of the pink striped variety. The rainbows more than made up for their lack of size; however, with their brilliant colors and spot patterns. I must admit that the competing anglers were a pain, and I missed my normal solitude enjoyed during weekday stream visits.

Arkansas River 05/02/2025 Photo Album

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.

Clear Creek 04/29/2025

Time; 1:00PM – 3:30PM

Location: Clear Creek Canyon

Clear Creek 04/29/2025 Photo Album

Weather was the main consideration for my choice of a place to fish on Tuesday, April 29, 2025. The high in Denver was projected to reach the mid-sixties, and that translates to frigid temperatures at higher elevation destinations. My choices were confined to the foothills and lower elevation locations. After three long drives during the previous week, I was reluctant to undertake another lengthy trip. In 2.5 hours on Monday I experienced decent success in Clear Creek Canyon, so I decided to take advantage of the short drive, and returned to the nearby stream.

Curved Position

The high temperature in Clear Creek Canyon was forecast to reach 61 degrees, but wind was a factor, and rain and cooler temperatures were expected to predominate from 3:00PM onward. I decided to forego morning fishing, and instead I headed to Prospect Park with Jane for some pickleball. I packed the car with everything I needed for an afternoon of fishing, and I departed the park by 11:15AM and arrived at my chosen parking lot by noon. The wind was gusting, and I decided to take advantage of the car and downed my lunch before gearing up and departing for Clear Creek.

Pocket Water

I swapped my pickleball shirt for my long sleeved Under Armour thermal undershirt, and then I slipped on my light down North Face and added my raincoat as a windbreaker and protection from the forecast rain. Once I was prepared, I hiked along the path for .2 mile, and then I crossed the creek at a wide tail section to reach the south bank. I began my day at 1:00PM with a tan mini chubby, an olive perdigon, and a sparkle wing RS2. I began working my way westward along the left bank, and I tossed the dry/dropper in likely locations.

Stretched Out

Nice Pool

I persisted with this style of fishing for the next 2.5 hours, and I landed nine trout. Two were rainbows and the remainder were browns. I never observed a rising fish until the last twenty minutes, when the wind kicked up, and a huge black cloud began delivering rain, sleet and snow. My hands were too cold to change to a double dry, so I continued with the dry/dropper and landed two decent trout. One of the late trout snatched the olive perdigon, and the other crushed a yellow fat Albert on the surface.

A Bit Larger

After building the fish count to five between 1PM and 2PM on the strength of the tan mini chubby, the olive perdigon and the sparkle wing; I encountered an extended lull. Two of the first five landed fish took the mini chubby, one nipped the sparkle wing RS2, and the other two gobbled the olive perdigon. During the lull, however, the resident trout began to refuse the tan chubby, so I made a change.

Productive Water

One of Two Rainbows

I substituted a yellow fat Albert for the mini chubby, and I replaced the sparkle wing RS2 with a psycho prince. The dry/dropper clicked for two trout, and eventually I replaced the psycho prince with another sparkle wing, when I spotted a few rising fish during the onset of the extremely foul weather.

Raised Up

Tuesday was a decent day on Clear Creek, although I never encountered a decent hatch similar to that which entertained me at the start on Monday. I worked hard for nine trout and covered a decent amount of stream real estate. The mini chubby produced a few fish, and that lured me into staying with it longer than I should have, even though it was the object of refusals during the second hour. A blustery storm that caused a rapid drop in temperatures, chased me from the creek when my hands began to sting.

Clear Creek – 04/28/2025

Time: 1:30PM – 4:00PM

Location: Clear Creek Canyon

Clear Creek 04/28/2025 Photo Album

As I looked ahead at the last week of April, the weather forecast was not conducive to fly fishing across much of the state. In addition, I tested the air conditioning system on the Saturday, when the high temperature poked into the upper 80’s, and the unit was not cooling the house efficiently. The HVAC repairman visited on the following Thursday and ordered a replacement part, and he was scheduled to return on Monday morning.

I checked weather reports in towns near possible fishing destinations, and I concluded that I could sneak in a few hours on Clear Creek, if the wind was not overly onerous. The section of Clear Creek that I targeted is only 45 minutes from my home, so it was a viable option for a half day after the HVAC experts were finished.

Theo’s Thing

By 11:00AM the two man crew departed, and Jane returned from pickleball, so I downed my lunch and departed for Clear Creek Canyon. By the time I made the drive, pulled on my gear, assembled my Sage four weight, and hiked and waded to the creek it was 1:30PM. I decided to test the streamer fly that I freelanced, while my grandson, Theo, looked on. In honor of Theo’s input I named it Theo’s Thing. I flicked the streamer through a long but relatively narrow pool along the left bank for ten minutes, and I actually observed a trout, as it followed the baitfish imitation; however, it did not seal the deal.

Early Success

I circled around a pair of wading anglers and another fisherman seated across from the parking lot, and moved upstream along the left bank. I was considering a change to another more proven streamer, when I noticed a couple rises in a nice deep shelf pool across from my position. I considered abandoning my streamer project, but I was hesitant to spend time switching out my line configuration. The trout made my decision for me, as at least five or six began to sip something tiny from the surface in a fairly regular rhythm.

Many Rising Fish in the Pool Behind the Exposed Rock on the Left

I snipped off the streamer and tied on a peacock hippie stomper and trailed 5X tippet off the bend and added a CDC blue wing olive. I began lobbing casts across the swift center current with reach casts, and I managed to land four small brown trout in the nine to eleven inch range over the next hour. The shelf pool featured some funky currents with an eddy at the top and then a long wide glide at the tail. It was difficult to produce a drag free drift with the conflicting currents, and the strong wind was not aiding my efforts. In addition to the landed trout I endured a few momentary hook ups, as tracking the tiny olive was a challenge even with the leading hippie stomper.

Grand Colors

Eventually the sun peaked out a bit, and the hatch waned, so I moved upstream to some riffles of moderate depth. A pair of fish refused the hippie stomper, but their reckless behavior allowed me to spot their holding positions, and a bit of persistence resulted in two more blue wing olive eaters.

The Bubbles Held a Rising Fish

Another move brought me to a nice shelf pool that resulted from man-made stream improvement structures, and it was here that I lost my awareness and hooked an overhanging tree. My flies dangled up high and out of reach, and I lost the hippie stomper and CDC BWO to a limb.

Not Bad

I concluded that the dry fly action was over, and the creek structure ahead featured much faster water and pockets and was not conducive to dries, so I made another change over to a dry/dropper arrangement. For this session that extended to the end of my day I knotted a tan mini chubby to my line and added a 3.5 foot 4X tippet connected to an olive perdigon. Another 1.5 feet below the perdigon held a size 22 sparkle wing RS2. If this sounds familiar, it was, as the perdigon and RS2 combination have evolved into a favorite offering this spring.

Mini Chubby Eater

Fly Removed

The revised lineup produced, and I doubled the fish count from six to twelve over the remaining time on the creek. Much to my amazement, two browns smashed the mini chubby. One grabbed the RS2 on the swing and the others nabbed the olive perdigon. My last fish was a twelve inch rainbow; the only ‘bow to rest in my net on the day.

Eager to Cast Upstream Here

Monday proved to be a nice outing with twelve fish landed in 2.5 hours of fishing. The wind was rather strong at times, but I was able to wait out the worst gusts. Hitting a blue wing olive hatch was unexpected but much appreciated, and I thoroughly enjoyed the challenge of fooling small browns on tiny dry flies. Once again the tungsten bead perdigon did the heavy lifting, and the sparkle wing RS2 complemented it nicely. Two fish on the mini chubby was a total surprise. The flows ranged from 65 -75 CFS during my time on the creek, and the air temperature peaked in the mid-fifties. The creek was a bit tinged, but it did not seem to bother the trout.

Last Fish Was a Rainbow

Monday was one of my better days on Clear Creek in recent years, and I am contemplating another visit before the snow melt takes charge.
