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.

South Platte River 04/11/2025 Photo Album

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.

As a result of high winds, rain and a visit from my daughter I was unable to visit area streams between May 8 and May 13, 2024, so I was possessed with an abundant quantity of bottled up fly fishing energy. On Mothers’ Day, May 12, Jane expressed a desire to go for a hike in Rocky Mountain National Park. We fully expected to remain in the car, while we completed an auto tour with perhaps a short hike in our rain gear, as dark gloomy skies and steady precipitation were present at our home in Denver. Jane’s decision proved to be a huge winner, as the dreary skies parted to reveal blue skies and sunshine, when we drove west of Boulder, CO.

One of the reasons Jane chose RMNP was in order to enter the park without a reservation. The reservation system kicks off on May 24, so we were not restricted in any way. By the time we arrived at the Fall River entrance, the air temperature was in the mid to upper fifties, and the trails and pavement were completely dry. After looping by Sheep Lake and the alluvial fan, we drove on toward Bear Lake, but we detoured through Moraine Park, where we found a parking space in a huge mud puddle. We were surprised at the number of vehicles and park visitors given the adverse weather in Denver, when we departed.

We  completed a 5.6 mile hike along the Big Thompson to The Pool and back, and a byproduct of the entire day was gaining unfiltered intelligence about the stream conditions in Rocky Mountain National Park. I checked out Fall River, the Big Thompson and Glacier Creek; and all three remained relatively low and clear and solid options for fly fishing.

I made plans to test the small streams in Rocky Mountain in the near term, but for Monday I had my eyes on the South Platte River at Eleven Mile Canyon. During my last trip to this fishery, I landed eighteen trout, and this represented my high water mark for 2024. Could I repeat this accomplishment? I was optimistic. The flows remained at roughly 130 CFS, and the weather was reasonable with a high of 61 degrees predicted. My only concern was the clarity of the river, since a fair amount of rain or snow hit Colorado over the weekend.

130 CFS and Slightly Stained

I arrived at my chosen roadside pullout by 10:30AM, and I immediately crossed the road to scan the river. I was a bit disappointed to note stained flows, but I decided to give it a test regardless of the clarity. I wore my light down North Face parka, and I avoided my hat with earflaps. If you follow this blog, you know that this was a major milestone for this 2024 fly fishing season for this avid angler. Once I was prepared, I crossed the road and walked downstream a bit to a crossing point, and by 11AM, I began casting from the bank opposite the road. I rigged my line with a size 8 yellow fat Albert, a beadhead black mini leech and a flesh colored San Juan worm. After a fifteen minute trial period with no response, I removed the mini leech and replaced it with a weighted 20 incher to obtain deeper drifts, and a bit later I swapped the San Juan worm for a beadhead pheasant tail. In the half hour between noon and 12:30PM, I finally achieved mild success, as I landed two brown trout and one rainbow trout. These were relatively small trout in the ten inch range; however, I was pleased to finally get on the board. Two trout gobbled the pheasant tail, and one nipped the 20 incher.

First Fish of the DayRainbow Trout Before Lunch

At 12:30PM I paused for lunch on a small island in the middle of the river. After lunch, I continued my progression up the river, until I quit a 3:15PM. At 1:00PM I was stationed next to a long deep run, and a dark cloud obscured the rays of the sun. As expected the low light density initialed some surface feeding, and sporadic rises evolved into fairly regular feeding. I jumped at the opportunity to fish dry flies, and I quickly cut off the fat Albert and nymphs, and I replaced them with a double dry with a peacock hippie stomper in front and a trailing CDC BWO. Five or six trout made their presence known, and I began to lob across and downstream casts with quite a few upstream reaches to keep the line upstream of the flies. Unfortunately my flies were mostly ignored, until one aggressive feeder slurped the hippie stomper! This was number five, and I was quite pleased to guide it into my net.

Rising Trout to Blue Wing Olive Hatch in This Area

While the sky remained darkened by the clouds, I rushed to release the trout, but then I decided to experiment with a soft hackle emerger fished in the surface film. On the fifth cast a trout grabbed the emerger, as it began to swing at the end of the drift, but I was slow to react, and the fish quickly earned its freedom.

Late Afternoon Catch

Within minutes the clouds moved away and revealed the sun, and this weather change put an end to the hatch and the related feeding. I could see that it would be a while until the next significant cloud cover, so I reverted to the dry/dropper, and I rolled with the fat Albert, an ultra zug bug and a soft hackle emerger. The soft hackle emerger duped a small trout, and after a long lull, I replaced the soft hackle emerger with a beadhead hares ear, and the hares ear accounted for my last two trout to push my total fish count to eight.

I Like This Pocket Water Section

The last half hour was extremely slow with bright sunny skies, so I called it quits at 3:15PM and found a safe spot to cross the river to the steep bank on the opposite shoreline. I hoofed it back to the car and removed my gear. Monday was an average day in all aspects of fly fishing. I landed eight trout in four hours or two fish per hour, and this is a fairly average catch rate. The fish were all in the ten and eleven inch range. The weather was comfortable and the scenery was outstanding, so I regarded Monday, May 13 as a success. My next destination will, in all likelihood, be Rocky Mountain National Park, as I plan to take advantage of my scouting trip on Mothers’ Day.

I craved a double digit fish count day, as my high point in 2024 rested at eight. Yes, several outings yielded eight high quality fish, but more action offset by smaller fish was perfectly acceptable to this avid angler.

Monday, April 29 produced a weather forecast of high temperatures in the low seventies in Denver, so I assumed that this translated to acceptable temperatures in the mountains and foothills. I quickly reviewed my Weather Underground app for Lake George, and I was pleased to discover highs in the mid to upper fifties with cloudiness prevalent in the afternoon. Flows remained at 137 CFS, and this was encouraging after heavy rain on Saturday.

I made the drive and arrived at my chosen location by 10:00AM. I was disappointed to note that the dashboard thermometer registered 46 degrees, and a stiff breeze greeted me, as I stepped out of my Telluride. I swapped my high tech short-sleeved undershirt for a long sleeve Columbia thermal version, and then I layered up with fleece, light down and a rain shell. Once again I snugged on my billed hat with earflaps. Will winter-like weather ever depart from my fishing trips? For my casting tool I strung my Sage R8 four weight.

Scene of a Couple Rises

I decided to explore some new water, so I walked downstream along a path for .2 mile, and then I crossed and fished from the bank opposite the road. I began with a yellow size 8 fat Albert, a prince nymph and a beadhead hares ear nymph. Early in my venture I spotted two sporadic rises in a nice deep run along the roadside bank, but I was unable to create any interest in my nymphs in spite of imparting movement via lifts and swings. After fifteen minutes with no response to my flies, I swapped the hares ear for a sparkle wing RS2, but that move was a resounding non event. After forty-five minutes of fishing all the likely deep runs and moderate riffles with no action, I removed the prince nymph and replaced it with a 20 incher in an effort to generate deeper drifts along the bottom.

First Trout Was a Brown

Home of the Wild Brown Next to the Log

The move paid dividends, when I landed a very nice wild brown trout in a deep pocket along a fallen log, and the netted fish nabbed the 20 incher. Another fifteen minutes of probing resulted in another lull, and by 11:30AM I approached the parking lot and my car. A couple occupied the pool opposite the parking lot, so I used this as an excuse to warm my hands, and I sat on the tailgate in the sun and ate my lunch.

Type of Water Where I Was Swinging and Lifting

The air remained quite cold and windy, so I made no adjustments to my attire, and I returned to the river an acceptable distance above the fly fishing couple. Within a few minutes I hooked up temporarily with a brown trout, but it quickly evaded my efforts to bring it to the net, and I moved on and fished some very nice deep runs and pockets. I managed to land a couple rainbows that also favored the 20 incher, before I approached a series of long, deep and slow moving glide pools. At this point I was fishing the 20 incher along with a classic RS2, and I began to make casts across the river and allowed the flies to lift and swing at the end of the drift. This tactic worked, as several fish nabbed the 20 incher, and another pair grabbed the RS2, and the fish count mounted to a respectable seven.

Took 20 Incher on the Swing

Area Where I First Noticed the Hatch

I glanced at my watch and noted that it was 1:30PM, and some large puffy clouds skidded across the sky and blocked the sun. Instantly the wind kicked up, and a flurry of rises commenced across the pool. I could not resist the allure of dry fly fishing, so I paused to cut off my dry/dropper configuration and replaced it with a double dry that featured a hippie stomper in front and trailed a soft hackle emerger. Ten casts among the risers convinced me that the soft hackle emerger was not the answer, so I swapped it for a CDC blue wing olive. This did the trick, and for the next twenty minutes I executed across and down reach casts in order to place the tiny dry ahead of the stomper, and this succeeded a number of times, as I boosted the fish count to ten. This was by no means easy pickings, but it worked often enough to satisfy my craving for dry fly action.

An Early Dry Fly Eater

Suddenly the sun reappeared, and the wind subsided, and the fish stopped rising. The next section featured a myriad of fast water, deep runs and pockets; and the double dry did not seem well suited to prospecting without the benefit of visible fish, so I converted back to the dry/dropper. In this instance, however, I attached an emerald caddis pupa as the end fly. The change in strategy failed, and after covering a forty yard section, I arrived at the long bend pool. I paused to observe, and this break once again coincided with dense cloud cover, and the weather change resulted in the resumption of the baetis hatch, as a cluster of trout began to feed. Three or four lined up along the main current seam, and another pod sipped olives, where the main current fanned into moderate riffles.

Most of My Dry Fly Action Was Here

A Fine Wild Brown Trout

Once again I made the conversion to a double dry arrangement, and for the remainder of the afternoon I cast my flies across and allowed them to drift downstream to the greedily feeding trout. I had a blast, as I boosted the fish count from ten to eighteen, I called it quits at 4PM. I cycled through several CDC blue wing olives, as I sought flies with fluffed out dry wings, and after several landed fish the CDC became thin and matted. Eight fish in the net sounds impressive, but this transpired over two hours of fishing and quite a few waves of hatches, heavy cloud cover and increased wind velocity. The CDC puff worked often enough to keep me in the game, but it was also ignored on many drifts. I suspect that there were so many naturals on the water that timing played a large role in determining whether a trout would sip my fly or instead opt for a fluttering natural.

Hatch Feeder

At four o’clock the sun reappeared, and the hatch ended, and I surveyed the western sky. It was obvious that a huge blue sky gap was in progress, and I was unwilling to wait for another wave of low light and emerging mayflies. I clipped my flies to my rod guide and returned to the car satisfied with the knowledge that I reached double digits for the first time in 2024, and I enjoyed an extended BWO hatch and capitalized on it with some steady success.

Eighteen fish in five hours is a decent but not outstanding catch rate, and the largest fish was thirteen inches. Some of the rainbows appeared to be stockers, but several possessed the vivid markings of carryovers. The brown trout were clearly wild, and the two thirteen inchers were the best fish of the day. I look forward to more adventures on the South Platte River before the levels rise as a concession to snow melt.

South Platte River 04/19/2024 Photo Album

Brutal. Brutal is the word that comes to mind to describe my day of fly fishing on the South Platte River in Eleven Mile Canyon on Friday, April 19, 2024. The trout that I landed on Friday were some of the hardest earned fish of my fly fishing life.

After a challenging but productive day on Monday, I reviewed my schedule and the weather forecast for another opportunity to visit Colorado rivers and streams. I had to take my new/used car into the dealer on Tuesday for a warranty repair, and the work lingered into Wednesday and thus eliminated two weekdays from my fishing plans. Thursday was grandson care day, so that left Friday. I launched Weather Underground, and I noticed that a storm system was moving in on Friday afternoon. The predicted conditions looked very similar to Monday, however, the temperatures were forecast to be a bit colder, and the storm arrived a bit earlier in the day. I decided to roll the dice, and I made the drive to Eleven Mile.

My decision was immediately fraught with adversity, as the traffic south through Denver was heavy and slow. The weather was very foreboding with dense clouds, drizzle and a temperature reading around freezing. I expected the cloud cover to lift by Colorado Springs, but that was not the case; however, as I moved west of Woodland Park, blue skies appeared in the western sky. The dashboard temperature climbed marginally to 34 degrees. Much to my amazement the temperature blasted from 34 degrees to 45 degrees by the time I reached the small town of Divide at the top of Ute Pass. Normally increases in elevation cause the temperature to plummet, but apparently the radiant energy from the clear sky and sun more than offset the elevation gain.

I arrived at my chosen destination in Eleven Mile Canyon by 11:00AM, and the temperature there was 47 degrees. My trust in Weather Underground was momentarily renewed. I busied myself preparing for a day of fishing in the canyon. I already wore my Under Armour long-sleeved undershirt, and I layered up with my fishing shirt, fleece hoodie, North Face light down and rain shell. I felt like Michelin Man. For headgear I snugged on my billed hat with earflaps, and with an eye toward the rain and temperature plunge in the afternoon, I stuffed my fingerless wool gloves in my pockets and placed my handwarmer packets in my wader bib muff. I pulled my blue hand towel from my waders and stuffed it inside my wader tops for easy access. For casting I chose my Sage One five weight in  case I lucked into a larger fish or had to fight the wind.

I marched up the dirt road and cut down directly opposite the long pool with the large vertical boulders along the western bank, and I began my fly fishing day with a yellow size 8 fat Albert, an emerald caddis pupa and a size 22 sparkle wing RS2. I began in the midsection of the long pool and worked my way up to the head of the pool. When I cast along the current seam of the left most entering braid, the fat Albert plunged, and I reacted with a swift hook set. The trout on my line fought like a trophy, but fairly quickly I determined that I foul hooked a thirteen inch brown. Disappointment reigned, as I was forced to get my hands wet to release a foul hooked fish. The breeze quickly evaporated my wet hand, and I felt the dreaded stinging sensation of numbing cold. This was just the beginning. I reentered the pool between the head and midsection, and I began lobbing longer casts toward the faster and deeper main, entering current seam, and on one of these longer casts, a fish grabbed the trailing sparkle wing, as it began to swing. This fish was attached to my line briefly, before it turned its head and managed to spring free from the tiny size 22 hook.

Two other anglers arrived, while this action transpired, and they stopped to fish in the pockets just above the pool I occupied. I decided to move to the super big bend pool ahead of them, but when I entered the river to wade along the east bank to the flat rock casting platform, I spotted a flurry of subtle rises in the medium size pool just below the super version. I made some casts with the dry/dropper and activated jigs, jerks, and swings; but the trout were not interested in my subsurface offerings. I could not resist dry fly fishing, so I disassembled my dry/dropper rig, and I converted to a peacock hippie stomper trailing a CDC blue wing olive. For the next thirty minutes, while the sky darkened, and the wind accelerated, and I skipped lunch, I made a generous number of casts, and I managed to land the first two trout of the day. One was a brown trout, and one was a rainbow, and they resisted netting quite well. I also experienced a copious number of refusals and a few very brief connections. I switched to a soft hackle emerger for a bit hoping it would outperform the CDC BWO, but that was not the case.

The hatch was rather intense, but my fly was largely ignored except for the two outliers that I mentioned, so I seined the water with my stretch net. After an adequate time period of seining, I examined the results, and I found several small nymphs and a newly emerged adult. I snapped some photos, and this now confirmed that the impetus for the steady feeding was a baetis hatch.

As this scene unfolded, the two hopscotching anglers moved past me to the super pool, and I rued my decision to linger in the lower pool, but much to my surprise, they bypassed the main pool and progressed to the two braids above the bend. By the time I decided to move up the river, they departed and climbed the steep bank to the road. Based on the change in weather that was forthcoming, they may have made a wise decision.

I took advantage of my good fortune, and I advanced to the super bend pool, however, I crossed at the tail and approached from the northwest bank. During this time I paused to eat my sandwich and carrots, but I was so cold that I saved my yogurt cup for when I returned to the car. Once again the sky darkened and the wind gusted, and the trout on my side of the river began a gluttonous feeding spree. By now my hands were gnarled, and my feet and legs were developing rigor mortis, as the temperature began its downward spiral. Once again I succeeded in duping one very nice rainbow trout, but this success story was accompanied by three very brief hook ups. My fly was a close but not exact imitation, and, in fact, the rainbow grabbed the CDC BWO, as I twitched it before lifting to cast. Movement was clearly a trigger, but it was difficult to consistently emulate the fluttering of the tiny naturals.

I was curious to check out the other side of the pool, so I crossed at the tail and assumed my advantageous position on the flat rock. This offered the advantage of keeping my feet and legs out of the water. Unfortunately this move coincided with a brief break in the clouds, and although my comfort level zoomed, the fish paused their feeding.

After ten minutes of fruitless casting, I moved on to the narrow island and proceeded to the upstream tip. I paused to observe the flats below the steep bank, and in short order I noticed a small pod of trout sipping toward the middle of the area. I cautiously waded my half frozen feet to a position just below the sipping rises, and I began to cast upstream and then across. I did not experience any luck, but after a few minutes I created a minor tangle, and once I was free to resume, I noticed another angler above me along the left bank. I was not sure whether he arrived after me, or whether he was there first, so I exited and crossed and walked the opposite bank to a position above him, where his side of the river was bordered by a huge vertical rock. I was unable to spot rising fish, where I normally find them. Meanwhile the other young angler moved upstream away from the flats, and he shouted to me. I was unable to hear him at first, but eventually I comprehended that he was asking, if he could “throw” below me. I replied, “sure”. and I moved on.

I intended to check out the nice wide smooth pool above the next two bends, but when I moved to a spot, where I could see the pool, I found another fisherman claiming the pool. I decided to reverse to the super bend pool before that got claimed, but as I passed the flats I noted a nice pod of feeding fish. Since the other angler had moved upstream, I felt that I was sufficiently below him, and I also was now fairly certain that he arrived after me. I stopped to fish the flats.

For the next hour plus I executed a huge quantity of casts. There was a definite ebb and flow to the feeding. The sky was consistently dark, but it became even nastier from time to time, and during these periods the feeding frenzy became quite intense. My fly was largely ignored, but I did coax three momentary connections, and I hooked and landed three very respectable trout to raise my fish count to six. One of these fish was a very fine fourteen inch brown trout with large and vivid black spots. The last trout was a hard charging rainbow trout also in the fourteen inch range.

This time of angling success coincided with very adverse conditions for the human angler. My feet and hands ached. I pulled my coat zipper as high as it would go and tipped my raincoat hood around my hat. I alternated putting my hands in my wader bib muff to grasp the hand warmers, and I used the blue hand towel to absorb as much water from my skin as possible. In spite of these measures, my core sank to new levels of chill. At one point small snow pellets descended from the dark sky, and this coincided with the most ravenous feeding of the day. I fished on while pellets glanced off my head and hands and fly rod.

By 3:15PM I became concerned for my for my well being, so I stripped in my line and carefully waded back downstream to a crossing point and then climbed the hazardous steep and icy bank and returned to the car. It was a rare instance, when this devoted angler left the river, while plentiful bugs continued to hatch, and fish continued to gorge. That gives the reader some indication of how cold I was.

Although six fish in three and a half hours of fishing seems like a poor catch rate, I was quite pleased. The quality and size of the fish was exceptional, and I worked extremely hard for these fish. I am perplexed, however, with the lack of acceptance of my flies. I am giving serious thought to tying some new baetis flies including a parachute CDC dry fly and a nymph with an olive body and a more narrow profile. The photo of the nymph in this post is a good example of the lean form I intend to copy. The bugs and trout loved the nasty weather, but this angler did not. Hopefully I can find a warmer day with decent cloud cover for my next baetis hatch adventure.

South Platte River 04/15/2024 Photo Album

The hallmark of outstanding blue wing olive action is nasty weather, and Monday, April 15 was one of those days. I wrapped up our federal and state taxes on Saturday, and I decided to reward myself with a day of fly fishing. I was disgusted with my last visit to Eleven Mile Canyon on 04/03/2024, so I decided to seek redemption. There was some risk to this decision, however, as the weather app forecast wind speeds of 14 to 17 MPH during most of the time I expected to be on the water. The high temperature was projected in the mid fifties, and cloudy skies were predicted to roll in during the afternoon. The cloud cover clinched it, and I accepted the wind risk and made the two plus hour drive to Eleven Mile.

When I reviewed the dashboard thermometer upon my arrival, the temperature registered 54 degrees, and dried grass and riverside vegetation flapped in the regular gusts. I bypassed my long sleeve Brooks undershirt, but I slipped on my North Face light down and covered it with my gray rain shell as a windbreaker. With the possibility of larger than average fish, I assembled my Sage One five weight, and I departed along the dirt road that borders the river in the canyon. After .2 mile I found a reasonably negotiable trail over hard packed snow and descended to the river. I began my day with a yellow size 8 fat Albert, 20 incher, and a supernova baetis nymph. After a solid test period with no action, I exchanged the supernova for a sparkle wing RS2. I covered some very attractive water in the thirty minutes before lunch as well as the first hour afterward with no evidence of trout other than a couple very sporadic slashing rises near my starting point. I was convinced that I was on track for a repeat of April 04/03/2024.

Between 1:00 and 1:30PM I fished the long pool next to the high rock wall on the western bank. I ate lunch next to this section and carefully scanned the water for signs of a blue wing olive hatch, but none appeared. I probed the seams along the deep entering runs and then covered the midsection by dead drifting the nymphs with a sweeping swing at the end. Nothing. I was actually surprised to have the entire pool to myself, but the lack of action may have explained that circumstance.

I moved on and tossed a few casts into some marginal deep pockets along the left bank with no success, and then I skipped another deep run and pool and approached the super big bend pool. I was certain that there were abundant fish in the pool, so a lack of action could only be explained by fly choice or lack of appetite among the fish.

I perched on the nice flat rock that serves as a convenient casting platform along the left bank, and sure enough, I spotted many trout (and suckers) finning in the slow moving deep pool above and next to my position. I observed for a bit, and as I did so, several of the trout that hovered within the upper two feet rose and sipped something small from the surface. I began casting my dry/dropper, and I imparted various types of movements to my drifts including jigging, lifting and swinging; but the targets ignored my efforts and continued to occasionally feed. As time transpired, the frequency of surface rises increased, and I finally decided to commit to a dry fly presentation.

I removed the dry/dropper configuration and added a two foot extension of 5X tippet to my leader, and then I knotted a CDC blue winged olive to my line. The tiny wisp of a fly was difficult to track, but I managed to land three nice trout, two rainbows and a brown in the twelve to thirteen inch range, on the CDC BWO. This was by no means an easy achievement, as I experienced twenty unproductive drifts for each instance, where a fish ate my fly.

The fish in my vicinity seemed to grow wise to my presence, so I moved upstream to another large exposed rock right below the entry of the eastern braid of the river. A large eddy swirled the entering current, and several fish were facing downstream to intercept natural morsels as they swirled by an exposed rock. I switched from the CDC BWO to a soft hackle emerger, and I applied a heavy dose of floatant to the body of the emerger. This change in tactics paid dividends, when I hooked and landed a nice rainbow trout from the area where the current from the east braid met the main river current. As I rested my rod on the large rock to release my catch, I noticed that the slow water along the bank was blanketed with small blue wing olive cripples.

I pursued the super pool for a bit longer, but the sun came out and the rising fish ceased to appear, so I decided to advance up the river beyond the small narrow island that split the river into the east and west branches. When I reached the tip of the island, I slowly waded through the shallow water in the middle of the river and scanned the smooth left channel for signs of feeding fish. After a cautious approach, I was next to the faster moving upper section that fanned out into a nice smooth pool, and a few rises manifested themselves.

I returned to a size 22 CDC blue wing olive, and I began fluttering casts to the middle and far side of the river, but the fish ignored my olive tuft. After quite a few casts, I finally induced a take and landed a nice twelve inch brown trout. I remained in this area from 2:00PM, until I quit at 4:00 PM, and I added three more spunky fighters to my fish count. A fourteen inch brown trout with dark black ink spots was the prize of this time period. During this two hour window the sky darkened and the wind kicked up for long stretches, and these bits of nasty weather provoked some fairly intense feeding from the river residents. I executed hundreds of casts and toggled between the CDC olive and the soft hackle emerger, as I attempted to discover the fly that would induce confident takes. I never really found it, but I did experience six temporary connections, when the trout was barely pricked by my hook point. This indicated to me that my fly was very close to the natural, but something was slightly off. I should add that I added a hippie stomper as the forward fly in a two dry fly arrangement near the outset of the 2-4 hour time frame. Perhaps the one foot leader from the stomper to the baetis imitation was restricting movement a bit, and thus the timid takes and refusals?

As this madness unfolded, I became a very chilled human being. My feet were the worst, and they morphed into icy stumps. The wind blasted frequently, and I pulled my buff up over my ears, and that helped, but the stiffness and cold of my feet and legs progressed upward to my core. Fortunately the sight of ravenously feeding fish allowed me to focus my mind away from discomfort and on to the task of fooling fish.

Finally by 3:45PM I could no longer withstand the cold and wind, so I stripped in my line and hooked the CDC BWO to my rod guide. I traversed the narrow island, crossed to the east bank and climbed a treacherous steep bank to return to the Telluride. The temperature on the dashboard, as I drove north on the access road was 51 degrees. What happened to the high in the mid fifties? It actually got colder as the afternoon progressed, and that does not even address the wind chill.

When the sky darkened and the wind accelerated, the fish feasted. I endured the weather, and my reward was the most intense dry fly fishing of the season thus far. I admit that I was disappointed with the high number of drop offs, but I cannot complain about the long and steady hatch and the hot action between 1:30 and 4:00PM. A longer 5X leader from the indicator dry to the baetis imitation may be the answer to more consistent takes. Hopefully I will get another near term opportunity to test this theory.
