When I first considered a day of fishing on Wednesday, May 10, 2023, the weather forecast was very encouraging. The high temperature at Lake George was anticipated to be in the upper sixties with partly cloudy skies and wind speeds in the ten to eleven mile range. The hour by hour forecast predicted a thirty to forty percent probability of rain after 3PM. In retrospect after experiencing the day, the weather was very adverse. Heavy clouds were present all day with only thirty minutes, at most, of sunshine. In the early afternoon my fishing companion, Nate, and I heard rumbling in the western sky, so we found a large rock overhang and huddled there, until the lightning and thunder abated. After resuming our fishing, another storm cell rolled in, and in this case we absorbed heavy rain showers and small hail pellets. The remainder of the afternoon reflected the forecast with periods of rain, wind and overcast for the last 1.5 hours. Fortunately I packed a fleece hoodie and my New Zealand billed hat with earflaps, or our quitting time may have been munch sooner than 4PM.

Once again my young fishing partner, Nate, accompanied me on this adventure. Nate is an experienced spin and bait fisherman, but a relatively novice fly angler, and I really wanted to introduce him to a productive piece of water, that would position him to set new standards for quantity of fish landed. The good news is that he accomplished that goal. The bad news is that he suffered through the same adverse weather conditions that tested me throughout the day.

I chose the South Platte River at Eleven Mile Canyon because the flows were in the 77 CFS range, and the major freestones in Colorado were already demonstrating the impact of seasonal run off with high and murky conditions. In addition, I visited the South Platte quite a few times in 2023 in the area, and I had yet to be disappointed. Nate and I met at a convenient park and ride, and we continued our trip to the river, so that we were positioned to begin fishing by 11:30AM. The river displayed a slight tinge, but the flows were as advertised in the upper 70 to low 80 range. I chose to fish the left bank, and Nate moved along the right shoreline, which was closest to the fisherman path.

Intense

In the early going I featured a yellow fat Albert, beadhead hares ear nymph and salvation nymph, and before we broke for lunch, I managed to net three brown trout in the eight to ten inch range. All three munched on the hares ear. Nate, meanwhile, offered a foam hopper, and then knotted an emerald caddis pupa below followed by a chartreuse copper john. Eventually the copper john was swapped for a beadhead hares ear.

Early Going

Sure Bet

After lunch, Nate began to register trout at a regular pace. I noticed a series of rises, and not wanting to consume the time necessary to make a full conversion to a dry fly, I exchanged the salvation nymph for a RS2. The RS2 produced a fish or two, but the rises stopped, and that signaled an end to the subsurface action as well. I knew from surveying the quality of the water, that I was skipping fish, so I reconfigured with a prince nymph on top and the hares ear on the bottom. This move paid strong dividends, as the fish count began to climb at a steady pace. There was a streak when the prince was on fire, but eventually the hares ear resumed its status as the top producer.

Protected from the Elements

During this time period the first thunderstorm forced us to seek shelter under a small rock ledge overhead. When we returned, I made an excessive hook set with no resistance and hurled my flies into an evergreen branch behind me. I had swapped the fat Albert for a tan pool toy hopper, and I could see the hopper relatively close to the trailing nymphs. I acknowledged that retrieval was unlikely, so I applied direct pressure and snapped off the three flies. I was not a happy camper. I replaced the prince and hares ear with like flies, but for the surface fly I returned to a fat Albert.

Cast Over White Water?

For the remainder of the afternoon Nate and I worked our way up the river along opposite banks, and we raised our fish counters significantly. Nate tallied eleven landed trout, before we adjourned at 4PM, and I elevated my count to twenty-six. Most of Nate’s success came from the hares ear, but he also notched two feeders on the emerald caddis pupa and one eager trout that gobbled the hopper pattern. In my case I estimate that sixty percent of my catch was attributable to the hares ear and forty percent to the prince. I believe that the larger prince helped sink my flies, and this aided in my strong afternoon showing. Nate achieved double digits on flies for the first time, and he also netted the fish of the day, a fine wild fourteen inch brown trout.

Most of my fish were in the eight to eleven inch range with a pair of twelve inchers topping the measuring tape. There was one period during the second thunderstorm, when both of us were pelted by heavy rain and then slanted ice pellets, but this lasted for ten minutes and then moved on. My top locations were deep runs along fast moving current and long and deep pockets. The trout seemed to favor positions at the tail of the soft water, where currents merged and concentrated food. Slow moving pools were not productive, although the sections that we fished did not offer much in the way of deep slow moving water. The size of my fish was somewhat understated, but I had a blast moving quickly and prospecting upstream and landing trout at a steady pace. Nate, of course, was euphoric after his record day, and he was the proud owner of the largest fish landed.

I reviewed the flows on Colorado streams, and it was apparent that many of the freestones were already impacted by the developing snow melt on May 8, so I turned my attention to tailwaters. When I noticed that the flows on the South Platte River at Lake George were 77 CFS, I immediately turned my attention to that popular tailwater. The weather forecast suggested high temperatures in the upper sixties with wind speeds peaking in the low double digits.

I began my drive at 7:30AM, and this placed me at a favorite pullout along the river by 10:00AM. The air temperature, as I prepared to fish by my tailgate was in the low fifties, so I tugged on my fleece hoodie and stuffed my raincoat in my backpack. I was properly attired for the entire day, although from 3PM to 4PM some dark clouds rolled in, and this development in turn caused constant cold gusting winds. I was close to the end of the day, so I never took the necessary steps to remove my frontpack and backpack to access my raincoat as a windbreaker. I paid the price for this laziness, as I was quite chilled, while I walked back to the car.

Started Here

I fitted together my four piece Sage R8 four weight, and I decided to walk down the dirt road for .3 mile to a section of pocket water that I love. I passed an SUV with Texas plates along the way, and as I was about to reach my chosen starting point, I encountered another angler next to his Jeep Wrangler preparing to fish. Not wishing to invade his space, I reversed direction and went upstream to the bend next to the road and fished up the river from there through a wide section with numerous pockets and runs of moderate to shallow depth. I began with an amber ice dub chubby Chernobyl, a beadhead hares ear nymph and a salvation nymph, and I probed all the pockets and runs that displayed adequate depth to harbor trout. During this phase of my day I landed four small trout. One smashed the chubby, and two nipped the hares ear, and the fourth trout nabbed an RS2, that I substituted for the salvation nymph.

A Bit Larger Rainbow

At 11:45PM I exhausted the pocket water section, and I was concerned that I would invade the space of the Texan, so I climbed the bank to the road and hiked upstream, until I was a good distance above the Texas couple. The female of the pair was entertaining herself by walking two dogs, as her partner fished the river. I crossed the river and then hiked along the far bank for thirty yards, at which point I fished back up the river through a fast and deep section with a narrow bank of soft water between the heavy main flow and the banks. I was certain that an opportunistic trout would grab the RS2, as I swung it along the bank; but, alas, that was not the case.

Above the narrow chute I encountered a long deep slow moving pool, and a pod of fish began to rise to something quite miniscule. I observed the surface for a bit in hopes of identifying the food source, but I never saw anything on the water or above the surface. I decided to fish on top, and I removed the dry/dropper components and tied on a peacock hippie stomper and size 22 CDC blue wing olive. For the next fifteen minutes I fluttered the double dry to the pod of risers, but they fed around my fly but never ate my fake. The rising activity waned, so I adjourned to the bank and ate my lunch. After lunch a few rises resumed upstream from my position, and after quite a few fruitless casts, a ten inch rainbow trout crushed the hippie stomper for fish number five.

I released the small rainbow and continued my progression, however, the nature of the river changed to another section of fast flows and attractive pocket water. I decided to once again modify my approach, and I converted back to a dry/dropper. For this dry/dropper pass through the pocket water I resorted to a yellow fat Albert, a beadhead hares ear nymph, and I retained the classic RS2. A small brown rewarded me in one of the short pockets, and the fish count rested on six, as I approached a very long pool section.

Next to the Exposed Rock on Right Produced

I was not generating much action in the deep slow moving sections of the river, but I decided to cover the water with a few casts, before I moved to the generally more productive entering riffles to the pool. A strong run flowed along the far bank, so I placed a cast along the seam and allowed my flies to slowly drift downstream. On the third such pass, the fat Albert made a dive, and I immediately set the hook. I was shocked to hear a loud suction sound, as a large fish swirled, upon feeling the hook penetrate. I instantly knew that this fish was larger than the ten to twelve inchers that occupied my net thus far in the day. Sure enough, after several heart pounding dives and spurts, I caught a glimpse of my catch, and it was a huge rainbow trout. The underwater behemoth shot downstream several times, and I responded by releasing line. I maintained steady pressure and coaxed the elongated football upstream. When it reached the middle of the river across and below me, it executed an aerial leap, and then crashed back down with a thunderous splash. In a stroke of unusual fish fighting acumen I lowered my rod tip to avoid tippet shock from the heavy weight landing. I had a great view of my river foe, and it was a rainbow trout in excess of twenty inches with a torpedo shaped body. The fight continued, and I applied steady pressure and coaxed the heavy resistance upstream very gradually. Clearly this trout was larger than my net, so I began slowly wading up the river toward a place, where there was a shallow gravel shoreline. I hoped to guide the beast up onto the beach in case the net would not encompass the entire body. I was almost there, when the rainbow caught a second wind, and it flapped its tail and slid back to the middle to heavier current. Somehow in the process of doing this, it rolled over the line, and I noticed that the hares ear and fat Albert were now wrapped around and behind the head. At this point there was not much I could do other than swear, as the valiant foe turned and snapped off all three flies at a surgeons knot above the fat Albert. I could see the large yellow foam fly move downstream for ten feet, and then it disappeared. The reader can imagine my state of mind after this physical battle on the South Platte River.

Acceptable

Slack Water Was Ideal

I paused to gather my senses, and I waited for my body to stop shaking from the adrenalin rush, and I replaced the lost flies. I pulled out another yellow fat Albert, and did the same for the hares ear and RS2 and continued prospecting. In a short amount of time I landed a twelve inch rainbow on the RS2, but it was small consolation for the prize fish that escaped my capture. The catch rate slowed to a halt, and I considered my next move. The RS2 seemed ineffective, and I saw no evidence of BWO’s, although I never actually saw them during the surface feeding time frame, so I decided to replace the RS2 with an emerald caddis pupa. Why? I have no idea other than the fact that caddis season on the South Platte was approaching, and the emerald colored pupa has historically been effective during tough fishing periods.

Best Brown of the Day

The move worked, and I fished the three fly dry/dropper combination for the remainder of the afternoon, as I boosted the fish count from seven to fourteen. Most of the afternoon fish were in the nine to eleven inch range, but I also managed a pair of thirteen inch browns and a similar sized rainbow. The emerald caddis was the food of choice for all the afternoon fish, and the first pupa unraveled, so I replaced it with a fresh version.

A fourteen fish day in May is a respectable accomplishment, but I never felt the confidence that accompanies finding a fly that consistently produces trout. The emerald caddis was close, but I cast to many very attractive spots with no response, so I was not totally dialed in. Of course the story of the day was the one that got away. I will remember that battle for quite a while. I actually feel like I did quite well to maintain contact for five to ten minutes with a size 20 RS2 on a 4X tippet.

With a string of nice spring weather days in the forecast, I was anxious to take advantage. I managed to land ten trout on Sunday, but they were small and very discerning. I worked hard for ten fish, and I was ready for some new scenery for a day, when the weather was forecast to peak in the low seventies in Denver, CO. I checked all the front range flows, and when I noticed that South Boulder Creek below Gross Dam was rolling along at 40 CFS, I was fairly convinced that a hike into the canyon was my Monday destination. But wait a minute. The ongoing dam expansion project needed to be considered. I brought up the Denver Water construction web page, and the verbiage on the Fisherman Parking lot was confusing and vague. Not wishing to risk another thwarted trip, I decided to shift my attention elsewhere, until I had a chance to call the Denver Water phone number that was provided.

I turned my attention to the old reliable South Platte River in Eleven Mile Canyon, and the DWR water graph displayed a steady flow in the 50 – 60 CFS range. Perfect. I decided to make the drive once again, but I planned to fish a different section. I departed my house in Denver at 8:15AM, and this enabled me to park and be ready to fish by 11:00AM. The air temperature was around 60 degrees, so I skipped wearing an extra layer and stuffed my raincoat in my backpack just in case. After lunch a series of dark clouds rolled in from the west, and I took advantage of the rain shell to hold in body warmth. For my rod I grabbed my new Sage R8 four weight, and I was off to the river’s edge.

Probably Home to Trout

Morning Prize

My outstanding day can be divided into three discrete periods. At the start near the parking lot I opted for a size 14 peacock hippie stomper, ultra zug bug and beadhead hares ear nymph. This three fly combination was moderately effective, as I built the fish count to five before I paused for a quick lunch at noon. Two fish crushed the hippie stomper, and the other three nabbed the hares ear, but I covered a fair amount of very attractive water with no interest, so I did not feel locked in.

Honey Hole

Actually a Cutbow

Muscular Torpedo

After lunch I noticed a couple sporadic rises, so I decided to exchange the hares ear nymph for a size 20 classic RS2. What a move it turned out to be! I stood to the side and just below a fifty foot long deep run, and I began firing casts to the entering riffle. After a few fruitless long casts, the hippie stomper disappeared, and I found myself attached to a spunky and hard fighting rainbow trout. This scenario repeated itself eight more times, as I apparently stumbled into a rainbow trout party. The last of this rainbow trout windfall was a very thick fourteen inch rainbow, and it put up a heroic fight before surrendering to my net. Fourteen inches does that seem that remarkable, but this trout exhibited excessive girth for its length. This angler was quite pleased. From the same position I shot some casts to another shorter run where the river curled between some exposed boulders, and this redirection yielded two additional rainbows. Finally the action ceased, as I executed five or six fruitless casts, so I ended my second phase of Monday’s fishing and moved upstream to the next section, which was characterized by a narrow streambed and an abundant quantity of deep pockets and short deep runs.

Slick Look Promising

Brief Display

I never observed more than a couple blue winged olive adults earlier, but by now they were totally absent, and the fish were not displaying surface feeding, so I decided to revisit the dry/dropper approach albeit with some larger flies to enable deeper and faster drifts through the deep pockets. I knotted a yellow Amy’s ant with a gray body to my line and trailed a size 14 prince nymph and size 16 salvation nymph. This configuration signified the start of my third period of the day, and once again my change in approach paid huge dividends. I continued working up the river at a steady pace and incremented the fish count from fifteen to twenty-seven, before I stripped in my line and quit for the day. This segment of my day was the type of fly fishing that I thrive on. It was fast paced, as I dumped short casts into likely pockets and deep runs, and I held my rod high to keep the fly line off the water. Three to five casts were sufficient for each target location, and quite often a hungry trout snatched the trailing nymph and quickly found itself languishing in my net. All of the fish during this middle to late afternoon session fell victim to the salvation nymph, and the first normally indestructible fly actually unraveled a bit forcing me to make a change. Several of the deep nymph biters were very healthy brown trout, and I was quite proud to fool these normally wary feeders.

Love the Markings

By 3:30 I reached the top of the fast water section, so I hoofed it back to the car and drove up the road another .4 mile to a new pullout. I quickly tromped down to the river and spent thirty minutes fishing through another pocketwater section, where I secured a couple more rainbows to bring my total to twenty-seven. A lot more attractive water remained upstream, but it was 4:00PM, and I was tired and ready for my return drive.

Monday was easily my best day of the season so far from a numbers perspective, but a previous twenty fish day in Eleven Mile was probably at the top of the list from a quantity and quality perspective. Nevertheless, I relished the fast action and challenge of adjusting to the ever shifting tastes of the wild stream residents of the South Platte. Hopefully I can get quite a few additional successful days in before permanent run off and a trip planned to Iceland.

Monday, April 24 was almost a carbon copy of my trip last Wednesday with Nate. The flows were essentially the same, and the weather was very similar. The temperature was around 46 degrees, when I began at 11AM, and then it climbed to around 50 degrees by 1PM, before massive dark clouds rolled in. The onset of heavy clouds caused the air temperature to gradually fall into the mid-forties, but the blue winged olives relished the low light and wind, as they emerged continuously from 12:15PM, until I quit at 4:00PM. Unlike April 19, however, I wore my hat with earflaps and carried my fingerless wool gloves; therefore, I was prepared for the adverse conditions in the afternoon.

I arrived at my favorite parking space along the river by 10:45AM, and this enabled me to be on the river fly fishing by 11:00AM. I wore my light down coat and rain shell as a windbreaker, and I assembled my Sage One five weight for a day on the tailwater. When I was prepared, I hiked up the road for .3 mile and then slid down a gravel path to the edge of the river. During the course of my day on the South Platte I encountered only one other angler. I was quite pleased with this circumstance, but I am unable to produce a viable explanation. Perhaps the weather forecast scared off the fly fishermen?

Appreciated

Entry Run Produced

Between 11AM and noon I prospected the pockets and the faster entering riffles of three pools. My offerings were the yellow fat Albert, a size 12 20 incher and three different bottom flies. I began with an ultra zug bug and then switched to an emerald caddis pupa and finished with a classic RS2. The dry/dropper approach yielded one very nice cutbow that grabbed the 20 incher at the head of the long pool, where Nate and I ate our lunch on the previous Wednesday.

Poised to Release

I timed my progression, so that I arrived at the large bend pool by noon, and after I covered the wide entering riffle with the dry/dropper configuration, I retreated to the bank to eat my lunch. As I observed, small rings began to appear in the center section of the pool, and by the time I stuffed my lunch wrappers back in my backpack, the surface feeding advanced to the top of the pool and the faster current seams. I took the necessary time to remove the dry/dropper flies, and I replaced the last section of tippet with material from the new 5X spool that I purchased the previous week. My first choice for fishing the big bend pool was a soft hackle emerger, and I applied floatant and fished it in the surface film.

Initially the soft hackle emerger approach delivered positive results, and I netted two fine rainbow trout, but then the low floating emerger was rudely ignored. I spent quite a bit of time making fruitless casts, and then I converted to a CDC BWO, but that move caused no change, and the trout binged on naturals and paid no attention to my fly. The sun appeared for a brief time, and the hatch dwindled, so I decided to advance up the river to some additional favorite sections.

Dozens of Fish Feeding in This Area

The next spot was extremely smooth, and the rises were very sporadic, I made some casts from the side as well as downstream, but I was unable to initiate interest from the four or five active fish in technical water next to the steep bank below the road. After fifteen minutes I abandoned the smooth pool and moved upstream to the upper section, where a deep slow moving pool bordered a vertical rock wall {see photo above). The trout were going crazy in this spot, and I selected a CDC blue winged olive for this duty. I must have made between fifty and one hundred futile casts in this area, but two downstream drifts connected with spunky wild trout, and I elevated the fish count to five. My puff olives that I tied on Sunday were not setting the world on fire, but I was duping the occasional fish.

Love the Speckles

I carefully watched naturals, as they drifted next to my artificial, and it was obvious that movement was a key distinguishing characteristic. The upright wings of the naturals were fluttering, and the legs of the mayfly were skittering on the surface. I tried to flutter and twitch my dead drifted naturals, and one of the landed trout actually attacked my fly, when I made a quick back mend and jerked the fly, but imitating the natural movement of the mayflies was quite a challenge. Eventually I decided that I flogged this area excessively, and the fish were wise to my presence, so I climbed back on the path and circled around the only other angler that I saw on Monday.

Pleased With This Hard Fighter

I crossed the river and carefully waded to the next wide pool, where the river sluiced around several large exposed boulders at the top. Fish were rising steadily along the deep center run, as well as in the area, where the current fanned out into the slow moving bottom pool. I spent the remainder of my time on the river in this area and ratcheted the fish count up from five to ten. Several of these trout were very strong fighters, including a fourteen inch brown that put up some very stiff resistance with an unending series of dives and twists on the leader. During this period I exchanged the CDC BWO for one of my newly tied puffs that also contained three or four wraps of dun hackle behind and in front of the wing. This wing was not as dense as several others that I tied on Sunday, but it was taller and thicker than most of the CDC BWO’s in my fly box. I also added a hippie stomper as the front fly to improve my ability to track the tiny puffs. The double dry combination with the newly tied puff wing worked fairly well as evidenced by the five trout that mistook it for a natural, but this was by no means easy pickings. I made numerous fruitless casts in order to connect with five trout.

BWO Puffs

Lovely Colors

Throughout the afternoon the dark clouds blocked the sun, and the wind whipped across the canyon, while the temperature dropped to uncomfortable levels. On two occasions small ice crystals descended and bounced off my raincoat, but the precipitation never approached the levels of April 19. Without my earflaps I probably would have called it quits sooner, but my hat and hood and buff provided minimal comfort; and, of course, my thoughts were diverted by the presence of rising trout. By 3:45PM the sky brightened a bit, and this change in weather brought an end to the surface feeding. Sporadic rises continued, but without regular feeding, it was quite difficult to create interest in my fly.

I stripped in my line, hooked my fly to the lower rod guide and hiked back to the car. On Monday I once again endured adverse weather and enjoyed a lengthy session with wild trout rising to baetis mayflies. I managed to land ten trout, and all were in the twelve to fifteen inch size range. Several rainbows and one brown measured at the high end of this range, and most were very strong fighters. The remainder of this week is predicted to be wintry conditions in Denver, so I suspect I will avoid additional trips to the higher elevation locales that offer fly fishing opportunities. When it comes to fly fishing, I am not very patient, but the continuation of winter in Colorado will force me to wait.
