South Boulder Creek 08/22/2018 Photo Album
Due to technical issues I am unable to insert photos. If you click on the above link, you can view photos from this fishing trip. Hopefully I can resolve the problem soon.
Jane and I returned from Wyoming and Montana on Monday, and that was a bit earlier than planned. I caught up on some chores on Tuesday and cleared the calendar for a day of fishing on Wednesday. Since my outstanding visit on 08/09/2018 to South Boulder Creek, I was aching to return, in case the green drake activity intensified. Wednesday, August 22 would be that day.
I delayed my departure until 9:10AM in order to check on an issue at a store, when it opened at 9:00AM, and this enabled me to arrive at the kayak parking lot below Gross Reservoir by 10:30AM. Three other vehicles occupied the parking lot, and two fishermen were about to embark on the trail, as I threw on my waders and assembled my Orvis Access four weight. The air temperature was in the low 60’s, as I took my first step down the steep trail to the edge of South Boulder Creek. Flows were 117 CFS, and the water managers held the flows at this level for a week in a welcome and unusual display of cooperation with anglers.
I hiked a decent distance below the dam, and I passed a cluster of three young fishermen in the first section above the pedestrian bridge. I never encountered the two gentlemen, who departed as I was preparing in the parking lot. By 11:30 I was positioned on the creek in a nice section characterized with an abundance of pockets and tumbling riffles. I pondered my choice of flies and decided to begin with a parachute green drake. If the large western mayflies were in attendance, I speculated that the trout might react to a large dry fly regardless of the time of day.
It was a strong hunch, and it was on target. Between 11:30 and a lunch break at 12:15 I netted ten trout from South Boulder Creek. All of the beautiful wild fish chowed down on the size 14 parachute green drake, and I was in a state of euphoria. I sat on a large flat rock in the middle of the creek and consumed my sandwich, while I observed the water, and surprisingly I never saw a green drake in the surrounding air. The first seven trout were fooled by the green drake that duped two gorgeous rainbows on the North Fork of the Shoshone River in Wyoming, but then a feisty brown dragged my line over a sharp branch and snapped off the popular paradrake. The replacement was slightly larger, and it accounted for three additional creek dwellers, but refusals were part of the package with this fly.
After lunch rejections of the parachute green drake became more frequent, so I elected to switch to a size 14 comparadun with no ribbing. The smaller mayfly imitation was effective initially, but when I cast to a pool with smooth water, the trout once again inspected but did not eat my fly on a repetitive basis. I reverted to a parachute style; however, the new dry fly was smaller than the previous replacement for the lost fly.
In the early afternoon time frame the catch rate slowed from the morning blitz; however, enough trout consumed the parachute green drake to maintain my interest. I cast the low riding parachute to appealing pockets and deep runs, and a steady supply of positive responses enabled the fish count to climb to twenty-two. During the 1-2PM period rainbows began to dominate my net, and I was pleased with this shift.
At three o’clock I began my return hike; however, along the way I paused at a productive section to spray a few casts. The trout in this area rejected the parachute green drake, so I decided to experiment during my lingering time on the creek. I clipped off the drake and replaced it with a size 12 Jake’s gulp beetle, and I began to plop it behind exposed rocks. The ploy paid off as two trout smacked the terrestrial within five minutes of making the conversion.
I spotted several fish in a nice pool along the bank, but they darted upward and snubbed the terrestrial, so I paused to make yet another change. Several rises commenced along the edge of a nice long run above my position, and a size eighteen mayfly floated upward. This observation persuaded me to knot a size 18 cinnamon comparadun to my line, and the low floating mayfly imitation prompted a slurp from a pretty ten inch rainbow. The comparadun did not appeal to other trout in the pool, so after ten minutes of futile casting, I called it a day and completed the hike back to the car.
Wednesday was a fun and productive day on South Boulder Creek. Twenty-five fish was a rewarding experience, and the ability to confidently cast a single green drake for three hours was highly appreciated. Hopefully the flows will remain in the current range for the foreseeable future, and this fly angler will certainly return for more green drake action. I already restocked my boat box with my remaining supply of size 14 parachute ties from the winter.
