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.
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.
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.
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.
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.
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.
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.
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.
