Fall has arrived in full force across the valley. The aspens and cottonwoods are changing fast, painting the hillsides in gold and orange. With cooler nights settling in and shorter days, the rivers are running low and clear across the region. These conditions make for technical fishing but also offer some of the most scenic days of the year to be on the water.

Fishing on the South Fork has been solid, especially if you're willing to adapt to the conditions. While there are some foam eaters showing up in the afternoons—particularly on warmer days—it’s largely a subsurface game right now. Cloudy days have been turning on the streamer bite, with olive and black patterns producing well. On the upper sections, rubber legs and beadhead nymphs are getting consistent grabs. Down lower, worms and rubber legs are the go-to combo, especially in deeper runs and seams. Keep an eye out for overcast windows to maximize your chances with streamers.

The Snake has been fishing well, with Hecuba mayflies still bringing fish to the surface and Mahoganies beginning to make their seasonal appearance. Dry fly action has been good, especially mid-day, but fish are starting to get picky. Hopper-dropper rigs are still productive, but presentation is key—long, clean drifts in prime holding water are what’s getting eats. Focus on foam lines, structure, and slower seams where fish are staging. As always in fall, stealth and patience go a long way. However, get out there before the flows are dropped to their winter levels (starting sept 29th).
