South Platte River 06/18/2025 Photo Album

Baby sitting duties prevented me from fly fishing last Wednesday; however, I salvaged a fun day on a lake on Friday, June 13. Hurdles to the pursuit of chasing trout continued to plague me, as I contracted an illness that took me out of action late on Fathers Day through Tuesday; however, by Wednesday morning my energy was back. One nuisance symptom of my condition remained, but I felt well enough to embark on a fishing trip.

But where should I go? I eagerly tracked the receding flows on the freestones I love to frequent, as run off wanes, and I was surprised to see that the Arkansas River was already within the range of edge fishing. The Yampa River in Steamboat was actually prime for edge fishing, but the long trip made that option unworkable. I was nearly settled on the Arkansas, but when I checked the flows on Tuesday, I noticed a distinct spike in flows at the Salida and Nathrop gages. I was concerned that heavy rain on Tuesday caused the sudden increase, and perhaps this was accompanied by a loss of clarity. It was too late to call a fly shop.

Next to the Large Rock on the Right

When I checked again early on Wednesday morning, the spike leveled out at 1800 CFS at Nathrop, but I was reluctant to risk the long drive, and I wanted to leave before the fly shops opened at 8AM, so I defaulted to the South Platte River at Lake George. The graph of flows there was nearly an unending straight line in the 85 – 90 CFS range. I had decent success on my last visit there on 06/10/2025, and I assumed that conditions would be similar. I made the drive to Eleven Mile Canyon.

Very Respectable

By the time I arrived, geared up and assembled my Sage R8 four weight, it was 10:30AM. I began my day with a peacock hippie stomper trailing a size 16 olive-brown body deer hair caddis on an eighteen inch section of tippet. As I stood on the bank making my first couple casts, a trout rose next to a rock, and it was no more than five feet away from me. I dropped the flies in the current without even casting and allowed them to drift along the rock, and on the second pass, a very respectable thirteen inch brown trout aggressively smacked the caddis. It was quite an auspicious start to me day.

Early Beast

I added a second small brown, as I advanced up the river, but then the fly fishing gods exacted their payback for my early good fortune. First, I set the hook into nothing and launched the flies into a tree limb high above the river. After some persistence and an excessive struggle, I was able to bend the branch tip down to the river, where I was able to unravel and rescue the flies. Next I failed to pause to allow the flies to straighten before making the forward cast, and this error along with some gusting wind, caused the flies to confront me in a massive snarl. It was so bad that I had to cut off both flies and dispose of the tangled leader that connected the stomper to the caddis.

Fine Looking Area

After these two time consuming disruptions to my karma, I made a thirty foot cast across the river to a nice riffle next to some overhanging branches. I really thought it was a futile effort, but much to my amazement a decent fish smacked the hippie stomper. I raised the rod and connected and in the process lifted the nose of a decent-sized rainbow above the surface, but in a flash the fish was gone. I stripped my line in and discovered that both flies broke off, and I suspect I scarred the knot on the hippie stomper in my efforts to unravel the tangle.

Nice Rainbow

What else could go wrong? One more thing. I finally settled into a rhythm and began prospecting likely trout lairs, when another angler appeared and waded into the river no more than twenty yards above me. I was dumbfounded. I fished out a remaining attractive section, and then I climbed the bank and moved upstream. As I passed the angler, I told the invader that I assumed he did not see me, and that explained his presence in my space. He said that was the case, and then uttered “life can be hard”. I was again dumbfounded and simply shook my head. There was no apology or offer to move somewhere else. I hiked along the road a good distance, offering him a courtesy he did not extend to me, and then I cut back to the river.

Pleased

By now at least an hour had elapsed, but I began to fish my double dry in earnest, and the results were outstanding. I spotted very sporadic rises, and small caddis dapped the surface occasionally, and my hippie stomper and deer hair caddis seemed to be of interest to the river inhabitants. I boosted the fish count from two to fifteen, before I paused on an exposed mid-river rock for lunch. Among my catch were a couple twelve inch rainbows and four browns in the twelve to thirteen inch range, and one seventeen inch cutbow. Yes, you read that correctly. The beast rose and crushed the hippie stomper at the very top of a long pocket. I was shocked by this outlier.

Productive Water Ahead

After lunch at 1:00PM the game changed. The fish stopped responding to my double dries. I spotted a light yellow body mayfly slowly ascending toward the sky, so I swapped the caddis for a pale morning dun. Nothing. By 1:30PM I decided to replace the comparadun with a light gray deer hair caddis, and while paused to make the changeover, I pulled out my stream thermometer. I submerged it for more than two minutes in a spot with some depth along fast moving current, and it registered 66 degrees. Before I plunged it into the water, it displayed 77 degrees, so I knew it was functioning properly. 66 degrees represents the threshold of when one should stop fishing in order not to harm trout by playing them in elevated stream temperatures.

Cutbow Monster

It was only 1:30, so I decided to drive up the river toward the dam with the hope that the water temperature would be lower near the bottom release. I parked where I normally stop on early spring outings, and I hiked to the same sections that I was familiar with. I made some casts at the top of a nice long entering run to a medium sized pool, and this provoked a splashy refusal. Next, however, I once again tested the water temperature, and I was surprised to learn that the thermometer continued to register 66 degrees. I used my better judgement and called it quits at 2:30PM. The air temperature on the dashboard display was 80 degrees, as I began my return journey.

Fifteen trout landed in two and a half hours of fishing is very respectable, and quite a few were above average beauties. This was accomplished in spite of a series of time consuming disruptions. I fished only dry flies, and the fish were quite receptive to my offerings. The hot spots were the cushion in front of large exposed boulders, and quite often the trout grabbed the caddis, as I began to lift in front of the boulder to make another cast. Slight twitches and movement seemed to instigate trout predator behavior. The warm water temperatures were a disappointment, and I am concerned with a heat wave in the forecast for the remainder of the week. Could the water managers increase the flows? I am thankful that I carry a stream thermometer.

South Platte River 06/10/2025 Photo Album

With Ireland and jet lag in the rearview mirror, I was anxious to return to Colorado waters. Run off was in full swing, so my choices were limited to tailwaters or lakes. I checked the flows on the South Platte River at Lake George, and I learned they were in the 88 CFS range, and my choice became a no brainer. I love Eleven Mile Canyon, and flows in that range were a bit low but well within my desired range. Air temperatures were projected in the upper seventies, and that reinforced my desire to visit the canyon tailwater.

Prime Water

I arrived at my chosen pullout by 10AM, and as I geared up at the tailgate of my car, another angler ambled by on his way to fish the section that I chose. This irked me a bit, but it was open water, and he got there first. I wore only my fishing shirt and stuffed my raincoat in my backpack. My rod choice was my old Sage four weight. I was in a position to begin casting by 10:30AM, and my line displayed a size 14 peacock body hippie stomper and a beadhead hares ear nymph. In the early going I managed a pair of relatively small brown trout, and the hares ear accounted for both; however, spots that looked very attractive failed to produce. The hippie stomper was attracting attention in the form of looks and refusals, so I concluded that the fish were looking toward the surface for their meals.

Looking Up the Canyon

I removed the long dropper leader and the hares ear, and I replaced them with a one foot tippet with a size 14 olive-brown body deer hair caddis. Cha-ching. This pairing clicked, and I moved the fish count from two to ten before I broke for lunch at noon. Credit goes to Max of Charlies Fly Box who posted an Instagram video that recommended caddis in the riffles for fast action. His advice was accurate.

Olive-Brown Deer Hair Caddis on Its Nose

After lunch I continued my advancement through pocket water and riffles, and I increased the fish count to fourteen by 1:00PM. By now the sun was bright and the air temperature was in the upper seventies, and it seemed that these conditions placed the trout in a state of lethargy. The double dry suddenly failed to attract interest, so after a long dry spell, I returned to the dry/dropper methodology. I spotted one solitary golden stonefly, so I chose a tan body mini-chubby Chernboyl as my top fly. Beneath it I brought back the hares ear, and then I added a second nymph in the form of a salvation nymph. The length of the leader from mini chubby to salvatoin was around four feet.

Pockets to Pick

I cast to all the likely spots, but it was as if the river was a victim of a recent fish kill. I removed the salvation and replaced it with an olive perdigon. After an enormous amount of casting and moving, I managed to land two nice rainbow trout in the final two hours. One bow snagged the hares ear, and the other clamped down on the olive perdigon.

Promising

On the day I landed four rainbow trout with one chunky specimen approximating thirteen inches in length. A brown trout stretched the tape to thirteen as well, and the other rainbows were around twelve inches in length. The remainder of the catch were less than a foot long.

Another Fine Rainbow

While both dry flies were working, the deer hair caddis was preferred over the hippie stomper. I estimate that the ratio of caddis dry fly takes to hippie stomper takes was seven caddis for every three stompers. Moderate depth riffles and medium depth and long pockets were the most productive river structures. The big deep pools were a waste of casting energy.

Run Near the Bank Delivered

A sixteen fish day, while most of the waterways were blown out with high water, was appreciated greatly. The last two hours were tough, but the morning action was fast and very entertaining. Perhaps another visit to the South Platte is in my future.

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.

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

South Platte River 04/23/2025 Photo Album

I should have returned to the Eagle River. Well, not really, but Tuesday failed to meet my high expectations. I marked April 23 as an Eleven Mile Canyon day, after I noticed that the high temperature in Lake George was forecast to be 65 degrees with wind speeds in the upper single digits and fairly heavy cloud cover in the afternoon.

I arrived at my standard parking place a bit after 10:00AM, and the dashboard temperature displayed fifty degrees. I was wearing a long sleeve thermal undershirt, and I added my fleece hoodie and my rain jacket as a windbreaker. My Sage One five piece was once again chosen as my casting stick.

A Good Place to Start

As was the case during my last visit to Eleven Mile, I decided to focus my energies on the pockets and faster sections between the pools, until I observed consistent rising fish. In response to this strategy I began fly fishing with a size 8 gray-bodied chubby Chernobyl and trailed a 20 incher and olive perdigon. I prospected the deep pockets and runs around exposed boulders for the first 1.25 hour, but I failed to coax any action.

By noon I encountered another angler in the long smooth pool with a high vertical rock wall along the west bank, so I circled around him and found a nice rock to perch on, while I consumed my lunch.

This Area Yielded Two Trout

After lunch I decided to change up my flies, as I felt I was packing too much weight with the 20 incher and perdigon, and this was constraining the movement of my nymphs. I replaced the 20 incher with a size 16 beadhead hares ear nymph, and I retained the perdigon. After this change, I landed a rainbow and brown trout in the riffles leading into a nice pool. These fish were in the ten to eleven inch range, but they were much appreciated nonetheless.

Pretty

Next I moved upstream, and I traveled quite a distance with no fish to show for my persistence. I fished some pockets and then the entering runs in two attractive pools, but the fish were apparently suffering a case of lockjaw. The sky darkened at 1:00PM, and I was certain that the chaos of a hatch was imminent.

Produced the Best Fish of the Day

Not wishing to miss out on nymph activity prior to the hatch, I once again revised my lineup, and I switched the olive perdigon to the upper position and replaced the hares ear with a sparkle wing RS2 size 22. Finally in the long riffle section on the western braid above the bend pool, the chubby dipped, and I found myself linked with a hard fighting rainbow trout. I battled the pink striped warrior for a few minutes and eventually slid my net beneath a chunky specimen in the fifteen inch range. The RS2 was tucked in the outer cartilage of the mouth, and I felt very fortunate to land the fish of the day.

Very Pleased with This One

Early Release

My expectations elevated with this catch, but I proceeded to endure another long dry spell. The sky continued to alternate between brief periods of sunshine and longer spans of dense cloud cover. I was perplexed by the lack of baetis action in spite of the near ideal conditions for a mayfly hatch. I persisted with prospecting the dry/dropper arrangement in likely holding lies among the exposed boulders and pockets, and I managed to finally up the fish count to five with two twelve inch brown trout.

Once again, however, I suffered an extended drought, and the RS2 was not receiving attention, so I decided to test the waters with an orange scud. Why? Many years ago orange scuds worked on the South Platte during the late April and May time frame. Eleven Mile Canyon harbors dense aquatic growth, and scuds favor this type of environment. The flows recently increased, so this suggested scuds were dislodged. Although I did not witness any spawning rainbows on this trip, I did see some on April 11, and I theorized that the orange scud could also imitate a rainbow trout egg.

Not long after my fly change, the chubby dipped, and I set the hook, and I was connected to a very vigorous and hard fighting rainbow trout. It jumped several times, and during these aerial acrobatics, I could see that the orange scud was the food of choice! My thought process paid off, but unfortunately this would be the last trout that feasted on the orange scud.

Lowered

I continued drifting it below the olive perdigon, and the perdigon added another fish to boost the fish count to seven. Two anglers approached me from downstream, and another blocked my progression upstream, and it was 3:00PM, so I decided to call it quits. However, instead of mounting the bank with a very dangerous steep lip at the top, I followed the path along the river.

Long Run

In doing so, I revisited a nice long run that fed a deep pool. I skipped this location on my way upstream, since another angler that was working downstream had recently disturbed the area. I paused to observe and immediately spotted a few sporadic rises. I decided to invest more time in pursuit of the risers with dry flies.

Sleek

I removed the dry/dropper paraphernalia, and I tied on a size 20 soft hackle emerger and applied floatant to the body. On the second cast a twelve inch brown trout smash the emerger, and I thought I was in the money. That proved not to be the case. The remaining sporadic risers refused the emerger style fly, so I made yet another change. I added a size 14 peacock hippie stomper and added an eighteen inch 5X leader to the bend and knotted on a size 22 CDC blue wing olive. The ploy worked, and I landed another small trout from the long run, and then I moved downstream to the next extensive pool and fooled two more trout in the entering riffle area. What an ending to my day!

I managed to land eleven trout on the day, and this included a fat fifteen inch rainbow, a feisty fourteen inch rainbow that ate an orange scud, and three respectable brown trout in the twelve inch range. A late and very sparse blue wing olive hatch finally generated some surface feeding, but it was very spotty, although I did manage to capitalize with four trout on a dry fly. The weather was rather nice for the normally icebox-like canyon, and I covered quite a bit of river real estate. It was a slow day, and the expected dense baetis hatch never materialized, but I made the best of it.

I had my eye on Eleven Mile Canyon with the anticipation of intersecting with a decent blue wing olive hatch. In past Aprils I enjoyed some excellent days on this river with the benefit of abundant quantities of the diminutive mayflies. Early in the week the weather suggested highs in the low seventies with partly cloudy skies for most of the afternoon. The temperature aspect of this forecast remained in place; however, the cloudiness was replaced with bright sunshine and clear skies. I decided to follow through with my commitment, and I made the drive to Eleven Mile Canyon on Friday, April 11, 2025.

Next to the Rocks

I arrived at my usual pullout by 10:00AM, and the dashboard temperature displayed at 51 degrees. In response to the chill, I pulled on my Under Armour long sleeved thermal undershirt, and then I added my fleece cardigan and my raincoat as a windbreaker. It is always windy in the spring in Colorado. For a casting tool I chose my Sage One five weight.

Love the Deep Water Next to the Large Rock

Given the weather forecast and the absence of clouds, I expected very little surface feeding; however, I surmised that baetis nymphs would be active. In response to this thought I began my day with a size 8 chubby Chernobyl trailing a size 16 olive perdigon and a size 22 classic RS2. I also adopted a strategy of skipping the pools in favor of pocket water, moderate riffles and deep current seams.

Perfect Water for My Tastes

In the 1.5 hours until lunch at noon, I managed to land three rainbow trout in the ten to eleven inch range. I also connected momentarily with several fish, and I foul hooked a rainbow that was my best fish of the morning. I might have hooked it in its mouth, but in its efforts to escape, the fish may have shed the upper nymph and been snagged by the trailer.

Melon Color

I adhered to my strategy and skipped around five pools, before I paused for lunch on a nice large and flat rock at noon. After lunch I progressed up the river and skipped around  three additional pools, and several were occupied by other anglers, so that worked out nicely. The other fishermen favored the pools, and they left the intervening pockets for my prospecting.

Humpback Brown

At one o’clock  the drifts that were previously ignored suddenly began to attract attention. Trout began to attack the nymphs especially on the lift and swing. I continued migrating up the river, and I landed an additional seventeen trout to boost my fish count from three to twenty. I would not characterize the action as intense, but it was steady. Three of the landed trout were rainbows in the thirteen inch to sixteen inch range, and I was quite pleased with these catches. Another four were respectable browns of twelve to thirteen inches, and the remainder were beneath the twelve inch threshold.

Seam Produced

Both the perdigon and RS2 delivered results, but the RS2 probably accounted for a higher ratio of netted fish, and that split could have been even greater had the tiny fly held on more temporary hook ups.

Number 19, Best of the Day

I moved at a fairly fast clip and did not dwell in any particular location. In most cases I executed five casts with several being a dead drift and an equal number activated with lifts and swings. The dead drift seemed to work on a directly upstream cast, while the swing and lift were effective on casts across and down.

Angling Competitors

In spite of the lack of clouds, Friday was a splendid day. I hit a new high for a day of fly fishing at twenty landed. The quality of the fish was satisfactory, although the average size was less than Wednesday’s haul, and it fell short of spring trips to the South Platte in previous seasons. I covered .8 mile of the river and adhered to fishing the faster water, and it paid off with solid results. I will continue to look for cloudy, cool days in Eleven Mile Canyon in order to experience the frenzy of a dense hatch and hot dry fly fishing.

With weather on Wednesday projected to be similar if not nicer than Monday, I booked another fly fishing trip. For this outing I selected the South Platte River in Eleven Mile Canyon. Even the renowned icebox in a canyon was expected to reach high temperatures in the low sixties.

I arrived at my favorite pullout at 11:00AM, and after my usual preparation and a short hike, I was perched along the edge of the river ready to cast by 11:30AM. Because of the shadows and the nine mile per hour wind, I slipped on my Under Armour long-sleeve thermal undershirt, and I added my fleece hoodie along with my rain shell as a windbreaker. I was comfortable for the morning and early afternoon, but I was forced to remove my raincoat and unzipped my fleece during the warmest part of the day from 1:30PM until 2:30PM. My rod choice was my Sage One five weight in the event that I hooked up with a larger than average trout.

Good Start

The flows were quite low at 64 CFS, so I expected technical fishing, but I selected a size 8 amber ice dub chubby Chernobyl nonetheless. I knew that the heavy foam fly would create a splash, when it landed in the river, but I planned to counter that concern by fishing the edges of faster and deeper water. For subsurface offerings I knotted a 20 incher as the top nymph and an olive perdigon as the anchor fly.

Home of Number One

In the hour before I broke for lunch at 12:30PM, I landed two very respectable rainbow trout in the thirteen inch range. Both nabbed the perdigon, and one emerged from a deep pocket, and the other came from a long deep run near the left bank.

Rather Fine

I arrived at the long slow-moving pool with a huge vertical rock wall along the western edge by 12:30PM, and that is where I consumed my lunch. I carefully observed the pool for fish activity, but it remained still and devoid of action. After lunch I waded into the midsection, and I fanned casts to the entering runs and along the fast water seams, but to no avail.

Home of Number Two

A pair of fishermen appeared above me in the next smaller pool, so I crossed below them and walked along the opposite bank. I had my sights set on the large bend pool, but another angler preceded me, and he was stationed along the opposite bank, where one of the braids that bordered a small island reentered the main river. I thought about asking if he would mind if I fished the entering riffle, but I decided to keep moving, as I knew there was much productive water ahead.

I fished the west braid around the small island and then crossed to the flats next to the steep bank below the tunnel. I spotted a few fish in the flats, but without the benefit of hatching insects, I knew catching a fish with the low river levels was a long shot. I attempted a few casts from the right bank above the flats, but in the process I snapped off my olive perdigon. Needless to say, I was not happy about losing another fly with an expensive tungsten bead. I replaced the perdigon with a beadhead hares ear and combined it with an emerald caddis pupa. I moved on and skipped by the narrow area with a high rock wall and crossed the river at the ninety degree bend.

Next I approached another long smooth pool that featured some very attractive entering runs that flowed around several large exposed boulders. I covered this section quite thoroughly, but the fish failed to cooperate. The sun was bright, and no clouds appeared in the bluebird sky, and the temperature hit its peak. This was the time frame, when I removed my raincoat and unzipped my fleece. I looked at my watch and noted that it was 2:30PM, so I endured two hours without any action whatsoever.

Another Fish Count

I decided it was time for a change, so I swapped the chubby for a peacock hippie stomper and then combined it with the olive perdigon and a classic RS2 size 22. I began working my way through the pocket water above the large pool, after I circled around another pair of fishermen. Some large clouds slid above me and blocked the sun, and the wind kicked up a bit. I spotted one lonely blue wing olive, and suddenly trout began attacking my nymphs. The next three fish were beneath twelve inches, but I was pleased with the action. All three attacked the perdigon, as the slender olive nymph resumed its position, as the hot fly in my arsenal.

Perfect for Trout

I moved farther up the river and ended my day with two fine rainbow trout in the thirteen inch range. One nipped the perdigon, and the other chomped the RS2. I also experienced momentary hookups with three other trout, but they managed to twist free after a very brief connection. I suspect that the three escapees grabbed the tiny RS2.

I would by lying, if I said I was satisfied with my day. After a fifteen fish day on Monday on the Arkansas River, my expectations soared. Nevertheless, seven fish on March 26 is quite satisfactory for early in the season. Four of the landed trout were rainbows in the twelve to fourteen inch range, and three were below twelve inches. The weather was very favorable for March in the Colorado Rockies, and that was another positive. I am rolling into the 2025 season with a bit of momentum.

The continuation of summer-like weather deep into October had me yearning for another day of fishing. My recent visit to Eleven Mile Canyon was a success, and the flows remained at 107 CFS, and the weather forecast a high of 70 degrees at Lake George, CO, so I made the drive.

Quite a few cars occupied pullouts along the lower open section of the canyon, but I passed them by and arrived at my preferred wide pullout by 11:00AM.  Another car was present, but that angler was positioned downstream from the pullout in a very long and smooth pool. This did not interfere with my plans whatsoever, so I geared up and pulled my Sage One five weight from its case. I ambled up the dirt road along the river and found a reasonably safe path down the steep bank, after which I rigged my five weight with a peacock hippie stomper, salvation nymph and sparkle wing RS2.

Pockets Around Exposed Boulders

Using my last trip as a proxy for Wednesday, I decided to focus on the faster water and pockets around exposed boulders and only spend time in the large pools, if rising fish were present. I essentially adhered to this strategy up until 2:00PM. In the half hour before lunch I landed four small rainbow trout in the eight to nine inch size range, and these spunky fighters attacked the salvation nymph.

After lunch I swapped the sparkle wing for a prince nymph and positioned it above the salvation. This combination delivered two small brown trout, and then I finally landed an eleven inch rainbow. At the tail of a nice small pool, a trout grabbed the salvation nymph, as it began to lift and swing, and this rainbow proved to be a twelve inch specimen that boosted my fish count to eight. I was pleased with the catch rate, but the size of the trout was severely lacking.

Wide Riffle Area Delivered

Best of the Day

As I approached the large bend pool, another angler slid down the steep bank, and he was positioned across from me. I made a few half hearted casts to the run nearest to my side of the river, but then I stripped in my line and advanced to the bend. The upper portion of the gorgeous bend pool was occupied by another angler with pure white hair, so I once again skirted the area and moved around the bend to an area with a wide set of riffles that spanned the entire western braid. I typically give this stretch a decent amount of attention, but the results were historically lacking. On Wednesday I devoted quite a few casts, and toward the upper third of the moderate depth water, the stomper dove, as a magnificent fifteen inch rainbow snatched the salvation nymph. The nymph had barely hit the water, when it was greedily consumed. Number nine made my day, and I moved on.

Second Nice Rainbow Came from This Area

Headed Home

In a very non-descript slow moving spot that could not have been more than three feet deep, a fish suddenly darted to the surface and crushed the hippie stomper. I set the hook, and it immediately streaked downstream, but I arrested the run and coaxed it into my net. Another rainbow in the fat thirteen inch range looked up at me, and it was not pleased that I interrupted its feeding time.

I was now at the upper tip of the narrow island, so I decided to inspect the long, smooth pool next to the very steep bank that borders the access road. The sun was bright, and I considered removing my raincoat, but a large ominous gray cloud moved into the southwestern sky. I decided to wait. The decision proved prescient, as the temperature dropped, and a brief rain shower developed. As the weather turned, a sparse blue wing olive hatch commenced, and the long, smooth pool displayed some random dimpling

Top of Long, Smooth Pool

I decided to make the conversion to dries, and initially I tied on a size 22 soft hackle emerger and applied floatant and fished it like a dry fly. I executed across and downstream casts and drifts, but it was extremely difficult to track the low floating emerger in the glare. After some futile casting, I swapped the soft hackle emerger for a Klinkhammer BWO emerger, and although the white wing was more visible, the fish were uninterested. I paused to reevaluate, and I decided to revert to a smaller soft hackle emerger.

Dry Fly Reward

For some reason I cast upstream and to the left along a current seam, even though I never saw a rise there, and a nice fourteen inch rainbow trout sipped the low riding fly. My confidence rose, but additional casting in the pool proved fruitless, so I moved on up the river. I planned to hit the attractive pocket water above the massive pool around the bend, but when I moved to the top of the pool, I spotted some rises along the entering currents. I tried my soft hackle emerger and then exchanged it for a CDC olive, and after an abundant quantity of casts, I landed a small brown trout to elevate the count to thirteen.

The sun peeked out again and this ended the blue wing olive activity, so I converted back to a dry/dropper with the peacock hippie stomper, an ultra zug bug and a hare nation nymph. I worked these flies aggressively around exposed boulders and deep runs for another thirty minutes, but it seemed that the fish developed late afternoon lockjaw, so I shut it down and climbed the steep bank in preparation for a .6 mile hike back to the car.

Wednesday was an enjoyable day on the South Platte River. Thirteen was a decent quantity of fish, but the size was somewhat lacking, although three very respectable rainbow trout made my efforts worthwhile. I experienced a bit of dry fly action, and that is always welcome late in the season. If the weather holds, I hope to log a few more fun days on Colorado streams.

My cold was in the waning stages, and I was anxious to undertake another fly fishing outing. The brief visit to Clear Creek ahead of the impending storm on Saturday was not very satisfying, so I considered my options. It had been a while, since I fished in a waterway that was not a small mountain stream, so I checked the flows on the South Platte River at Lake George and the flows on the Arkansas River below Salida. The South Platte in Eleven Mile Canyon was hovering in the 105 CFS range, and the Arkansas was at 450 CFS. Both of these readings were within my ideal range, but I chose the South Platte, when I read that the tricos and blue wing olives continued to be active.

I arrived at my usual pullout by 11:00AM, and I was pleased to see only one other car parked below me, and that car was accounted for by a solitary angler in the long slow pool down the road from the pullout. The temperature display showed 53 degrees, so I pulled on my fleece cardigan and raincoat, and then I grabbed my Sage One five weight, in case I waged a battle with a larger fish.

Lunch View

Once I was prepared for a day of fly fishing, I hiked up the road for .25 mile, and then I angled down a steep bank to the the edge of the river. The water was extremely clear, and the flows were elevated a bit from my preferred level but certainly favorable for fly fishing. I added a 2.5 foot section of 5X tippet to the 4X that my guide tied to my tapered leader last Wednesday, and then I knotted a peacock hippie stomper, beadhead salvation nymph and sparkle wing RS2 to my line.

I began casting in some deep pockets bordered by large exposed boulders, and I experienced two long distance releases almost immediately. This was an ominous sign for the day, but I persisted and finally managed to coax some fish to my net. They were all small brown trout in the seven to nine inch range, but I was pleased to learn that the trout were tuned into my flies. The sparkle wing RS2 was the favored target of the trout in the early going.

After a half hour I encountered the long slow moving pool that entertained me repeatedly in the spring with dense baetis hatches and fast action. I moved immediately to the entering runs at the top of the pool, but on this day the trout were not interested in my offerings. After I devoted a concentrated effort to the runs, I decided to consume my lunch on a large rock on the bank above the pool. From this vantage point I could observe the entire pool in case some insect activity commenced.

Unfortunately that was not the case, so after lunch I continued my progression up the river. Another angler was above me, but a considerable distance existed between us allowing me to prospect some nice pockets before arriving at the next large pool. Once again I began working the pockets, and in a repeat of the morning, I landed four more smaller trout in the six to ten inch band of length. One was a rainbow and the others were small browns. Both the salvation and RS2 generated takes during this time period.

Fifteen Inch Brown Trout

I attained a fish count of eight rather early in my upstream journey, and I was pleased with this success, but I was puzzled by the lack of size and the absence of fish in the obvious large pools. Finally, in a deep elongated pocket below a slightly exposed boulder, I hooked and landed a superb fifteen inch brown trout. It snatched the salvation nymph, just as it began to swing in front of another boulder at the bottom of the pocket.

First of Two Gorgeous Rainbow Trout

Rainbow Home

This catch of a larger fish propelled my confidence, and I continued with the same strategy for the remainder of my time on the water, until I built the count to nineteen. During the day, I landed two trout in the fifteen inch range and one thick slab that approximated sixteen inches One of these was the brown trout described above, and the other two were rainbows. During the afternoon the salvation nymph became the breadwinner, or should I say fish winner? Movement was definitely a trigger, as many of the fish attacked, when the fly began to swing at the tail, or when I imparted a lift to recast. In fact I was amazed that several fish grabbed the fly, after it spilled over rocks at the tail of a pocket or run.

Decent Brown Trout

The other factor that defined success was identifying the water type that the trout preferred on September 23. As I discovered in the morning, they loved seams along fast water with large exposed rocks nearby for protection. I actually began skipping the large pools, and I targeted the faster runs and pocket water among exposed rocks in between the major pools. This worked perfectly, since some of the pools were occupied by other anglers, and I simply took advantage of the sections that they avoided.

The Type of Water That Produced

The fish count was perched on sixteen fish, when I began to prospect a nice wide pocket that spread out behind an exposed boulder. At the tail the water split around another exposed boulder and then accelerated into white water flumes on both sides. I made five casts to the top of the pocket with no response, and for some reason I allowed one of the drifts to tumble along the rock and down the flume. I decided to lift the flies to recast and avoid a potential snag below me, and as I did so, I felt the weight of a significant fish. Sure enough a gorgeous brown trout appeared, as it attempted to free itself from the hook that now penetrated its lip. I got a perfect side view of the trout, and I was certain it was in the fifteen inch range if not longer. I fought the fish and manipulated it into the pocket above the exposed rock at the tail, and then it turned its head and disappeared. My line dangled limply above the water, and when I stripped it in, I discovered that both nymphs were absent. Not all fish stories end on a positive note.

A Second Splendid Rainbow Trout

At one o’clock I noticed a dense swarm of mayflies above the river, that I assumed were tricos. Based on my experience, this was rather late in the day for the trico mating cycle. I carefully observed the downstream river for rising fish, but I never saw any. A bit later in the afternoon I noticed a very sparse emergence of blue wing olives, but once again the event did not produce any surface feeding. I persisted with my dry/dropper nymph rig throughout my time on the water, and I was not tempted to make the conversion to dry flies.

Rainbow Lived in the Run Near the Bank

Monday was an enjoyable day on the South Platte River. The temperature rose to the upper sixties in the afternoon, and I was actually a bit overheated in my fleece. The sky was a brilliant blue, and the foliage was in the early stages of turning into red and gold. I landed nineteen wild trout including three in the fifteen to sixteen inch range, a pair of feisty thirteen inch rainbows. and a couple standard twelve inch brown trout. The remainder were on the small side, but I appreciated them nonetheless. I closely observed the type of river structure that produced positive results, and I applied this knowledge to my angling progression to achieve decent results. For me, fly fishing is a continuous learning exercise, and that is what makes it my passion.
