North Fork of St. Vrain Creek 04/18/2018 Photo Album

Wednesday was more of a walk the dog day than a serious fly fishing day. Our son, Dan, and his fiancee, Ariel, adopted a dog named Zuni. On days when Dan travels and Ariel works, Jane and I enjoy dog sitting duties for our grandpuppy. Yesterday we transported Zuni to Mt. Falcon Park, where we hiked the Meadows Trail.

Thursday we decided to introduce Zuni to fly fishing. We packed the car with fly fishing gear and dog tending items, and we departed for the North Fork of St. Vrain Creek below Buttonrock Reservoir. First we detoured to the Highlands in Denver, where we gathered Miss Zuni, and we ushered her into the car. An hour and fifteen minutes later we arrived at the parking lot below the gate that restricts vehicle access to the Button Rock Preserve. Jane tended to Zuni’s high energy levels and constant curiosity, while I climbed into my waders and rigged my Orvis Access four weight rod.

We hiked for a good distance, while Zuni criss-crossed the packed dirt road in an effort to explore the stream, the boulders, the sticks, and the tall grass along the way. Finally we arrived at the location I chose for my entry point. Jane and Zuni remained as spectators for a bit, but my lack of action resulted in their exit, as they advance up the dirt road.

This Little Guy Was the First Fish of the Day

I began my quest for St. Vrain trout with a yellow fat Albert, beadhead hares ear, and beadhead salvation nymph; but this trio of flies was soundly ignored by the local stream dwelling residents. After thirty minutes of focused fishing I covered a fair distance including some quality pools, and the fish counter remained locked on zero. I decided to make a change, and I swapped the salvation nymph for a RS2. This move paid off, when I lifted the rod tip to make another cast in a medium sized pool, and a small brown trout latched on to the RS2. Shortly thereafter the same result occurred in another pool a bit farther upstream, and I was pleased to experience a small amount of success.

Another RS2 Lover

More upstream progress delivered me to a qualtiy pool above a huge collection of branches and sticks, and as I fired the dry/dropper into the depths, several fish revealed their presence with sipping rises. I halted my casts to avoid disturbing the water and observed for a minute. I spotted at least five fish in close proximity, and several moved back and forth snatching food from the drift, while two elevated to the surface and displayed occasional subtle sips.

Clearly these fish were seeking food in the upper one-third of the water column, and my nymphs were drifting below their area of search. I removed the three flies and tied a tiny size 24 CDC BWO to my line. I was very optimistic that this offering would deceive the pool feeders, but it was ignored in a manner similar to inanimate debris. Could these fish be selective to emergers in a manner similar to Monday on the Eagle River?

I decided to test my theory. I replaced the CDC olive with a size 20 Craven soft hackle emerger, and I applied a liberal amount of floatant to the body. I flipped five casts to the center and far side of the pool with no results, but on the sixth drift a nine inch brown darted to the surface and consumed the wet fly. I quickly reacted and netted the feisty eater. Once I photographed and released the small jewel, I glanced at my watch and realized it was 12:30, and Jane and I agreed to meet at the large outflow pipe at that time.

Soft Hackle Emerger Eater

I quickly clambered up the bank, and as I began walking at a brisk pace, I spotted Jane and Zuni coming toward me. We met, and Zuni showed excessive interest in my wading staff, and then we moved on to a nice spot next to a long pool. Jane spread out her outdoor blanket, and we enjoyed our lunches while Zuni rested.

After lunch I ambled a short distance to the head of the long pool and paused to observe. As I gazed at the far side of the pool, I spotted two dark figures, and then as I stared one fish elevated to sip a morsel from the surface. This of course confirmed that the items I sighted were fish, so I engaged in some long casts to the far side of the pool, while I was careful to avoid the large overhanging pine boughs. The closest fish seemed to look toward the fly several times, but that was the extent of its interest. Another fish several feet beyond the looker slowly moved to the surface to suck in a natural, so I shifted my attention to that target. I dropped a nice cast five feet above number two, and in a flash it darted upward and inhaled my offering. I responded with a short set, and then I guided the small brown to my net. As this transpired, Jane and Zuni looked on. I snapped a photo, while I held the fish next to the net, and then I extended it to Zuni. I was curious to see her reaction, and she responded with her first kiss. Well, it was her first kiss of a fish. I am not aware of the goings on during her frequent dog park visits.

Zuni’s First Kiss

After this fun episode I returned to the road, and I hiked back to the pool that contained five rising fish before lunch. I walked downstream beyond the intended pool in order to reach the shallow tail, where I could safely cross to the opposite side. As I progressed upstream along the far bank, I paused at the bottom of the long slow pool and launched a few casts to the smooth water above me. On the third drift I noted a bulge below the dry fly, and I set the hook and reeled in another small brown trout. I neglected to mention, that I switched the soft hackle emerger for a Klinkhammer BWO, and the recently added fly fooled the pool resident.

I continued to the pool inhabited by five trout, but the Klink emerger failed to entice any interest, and my watch indicated that it was time to depart. I once again scaled the steep rocky bank and hiked back to the parking lot at a brisk pace. I found Jane and Zuni cavorting about the parking area, and a dog water bowl was positioned directly behind the Santa Fe. I began to remove my waders, and a couple arrived with two dogs, and Zuni quickly introduced herself to a black female puppy. Apparently rough play is a necessary phase of dog introduction, as both pups frolicked and rolled in the parking lot for a bit.

Licking the Net

I was pleased to land five small brown trout in two hours of fishing on the North Fork of St. Vrain Creek. Despite the clear blue skies a brief hatch of blue winged olives attracted some surface feeders, and I capitalized by fooling three on dry flies. Not a bad day for a dog walk.
