Time: 1:00PM – 4:00PM
Location: Below Gross Dam.
Monday was the last day available for local fishing, before Jane and I depart on a trip to Canada. On Sunday we hiked the Peak to Plains Trail in Clear Creek Canyon, and I viewed this as a scouting mission. It was obvious that Clear Creek continued to run above the ideal range at 150 CFS, but I noted numerous nice pockets and slower moving pools along the edge that offered viable targets for my flies. As I drifted off to sleep on Sunday night, I was fairly certain that I would give Clear Creek a try on Monday.
The drive to Clear Creek from my house in Denver is a mere 45 minutes, so I completed my normal morning exercise routine. Part way through the morning I took a break and checked the DWR stream flow web site, and I noticed that Clear Creek was in the 140 CFS range and declining. I was curious to see how Denver Water was managing South Boulder Creek, so I scrolled up to that tailwater, and I was pleased to note that South Boulder Creek below Gross Reservoir was down to 144 CFS. This new information prodded me to reconsider my destination choice. I knew from Friday’s experience that green drakes were emerging on South Boulder Creek, and flows were now 20 CFS lower than the level that I endured on Friday. I surmised that green drakes would be absent by the time I returned from Alberta, so I modified my plan and targeted South Boulder Creek for Monday, August 14. Clear Creek could wait until late August.

I packed the Santa Fe and departed by 11AM, and this allowed me to arrive at the upper parking lot by noon. In order to avoid packing my lunch into the canyon, I devoured my sandwich, carrots and yogurt in the parking lot; and then I gathered my gear and assembled my Orvis Access four weight. Seven other vehicles were present in addition to mine, so I knew there would be some company on the stream. The air temperature was quite warm, as the dashboard thermometer registered in the low eighties.
Since I started late, I decided to shorten my hike, but I did cross the stream at the pedestrian bridge. Tools and supplies were present at the bridge, but workers were absent and probably on their lunch break. I continued along the Walker Loop trail for a decent distance, and then I found a relatively easy path down to the creek. I chose South Boulder Creek because of the possibility of fishing to a green drake hatch, so I tied a size 14 2XL parachute green drake to my line and began to spray searching casts to the likely trout holding habitat.

The first four trout interactions were refusals, but these fish appeared to be tiny, so I persisted with the parachute. After the dose of rejection, I hooked and landed two decent brown trout, and this affirmed the parachute green drake selection. Over the next 1.5 hours I built the fish count to six, as the parachute style green drake attracted enough attention to retain its position on my line. I estimate that I observed three refusals or temporary connections for each fish that landed in my net, but I suspected that the fish that ate the fly were larger than those that rejected it. In many cases I could see the side of very small fish, as they flashed toward the surface and then turned away.

At approximately 2:30 I reacted to one of the aforementioned flashes and executed an overzealous hook set. Unfortunately the trout never grabbed the fly, and it catapulted towad a tree branch behind me. I attempted to avoid the snag and quickly thrust my arm forward, but it was too late, and I snapped the parachute green drake off in the tree branch. In a futile effort to recover my fly, I bent down the small branches and inspected the leaves, and I found some flies lost by other fishermen, but I could not locate the coveted green drake. I declared it a write off and used the break off as an excuse to test a different green drake.
The parachute fly was very waterlogged and difficult to follow in the dim light that resulted from the heavy cloud cover and intermittent rain. I decided to try one of the ribbed size 14 comparaduns, as it possessed a large full upright deer hair wing. The choice was sound, and I increased the fish count to from six to fourteen with the comparadun on the end of my leader. During this late afternoon period rainbow trout became the predominant species. I am not sure if this was attributable to the different style of fly, the type of water, or the time of day. The afternoon section of South Boulder Creek was characterized by faster water, and rainbow trout generally tolerate more current than brown trout.

The first four landed fish after the fly change emerged from the stretch below the bridge, and the last four lived in the stream above the bridge. On my return hike I stopped at a nice series of pockets just above the pedestrian crossing, and I fooled a brown and rainbow in that area. Interestingly the final two fish came from some pockets in the wide relatively shallow area, that I normally use simply as a stream crossing point.

I was pleased with my decision to revisit South Boulder Creek, as I landed fourteen fish in three hours. Although it was quite warm during my hike down to the stream, storm clouds quickly moved in, and the mostly cloudy skies kept the air temperature quite cool for most of my time on the water. I never saw a green drake, but it was obvious that the local stream residents recognized my imitations. I suspect that the cool overcast conditions did not create an environment conducive to a green drake emergence, but the cause was irrelevant, because the trout ate my imitations. I endured a significant number of refusals and a few temporary hook ups, and the glare and low light made following the dark olive fly a challenge at times; but the action was steady, and the size of the fish was typical for South Boulder Creek.
