The fishing out there is beginning to change now that we have some cool weather under our belts here in the Roaring Fork Valley. The fish notice these annual cycles; therefore, feeding patterns, diet, and behaviors are starting to change, as well. We must take heed as fly fishers.

Over the next month, we still enjoy the prolific late summer/early fall hatches of the Roaring Fork Valley (especially on the Fryingpan River tailwater section), but those epic days are numbered. We need to take advantage while we still can. Flows are dropping now, and we need to consider stealth and accuracy to remain successful. Simply put: These fish have seen thousands of artificial flies over the last few months, and with slower and clearer water, the trout have plenty of time to inspect our fly and choose whether to accept it or refuse it.

The opposite argument can also be made here, as trout sense the lean and dark times on the horizon and start to feel a sense of urgency in regards to their caloric intake. This is the reason we have such incredible streamer (large baitfish imitations) fishing here in the fall, as is the case anywhere trout reside. During fall, large meals take a higher priority than chasing down tiny flies, especially for bigger trout.

Blue Winged Olives are officially back on the menu now and will take over top spot on the hatch chart, especially on the upper Fryingpan, Roaring Fork, and Colorado rivers. These tiny mayflies are the official heralds of spring and fall, and they are already hatching heavily in certain areas.

October and November are magical around here -- this is the time to experience a few less people, easier wading conditions, and vibrant colors. Late summer hatches will keep on rolling for another week or two, and our weather outlook looks terrific -- thank goodness!
