CURRENT REPORT
It's starting to feel like fall up Rock Creek. Cooler nightime temps have moved the best fishing window from really early, to mid-morning and on. We're right in between our peak terrestrial fishing and our amazing fall fishing. With a foot in each season, having a diverse selection of flies is key to finding success on Rock Creek.
Hoppers, beetles and ants still the main course on Rock Creek. Tricos also coming into the picture at our slightly before noon. While Rock Creek isn't home to much "trico water" (big, glassy, slow flats) you can still find fish feeding on on-top and subsurface. Mahoganies, BWOs and October caddis showing themselves more and more each day.
Be prepared to fish up Rock Creek two ways: dry-dropper fishing and dry dropper fishing with smaller attractors.
Dry-dropper fishing has been the most consistent way to fish Rock Creek. Up top, reach for a Chubby Chernobyl, Water Walker, Henneberry Hopper or Juicy Hopper in sizes #10-14.
Subsurface, reach for a Pat's RL, Twenty Incher, TJ, Jig PTs, Hares Ears, Shuck-its, Duracells, purple perdigons and Blow Torches. Anglers are starting to focus on Mahogany mayflies and October caddis subsurface. While these hatches are famous among dry fly enthusiasts, matching these hatches subsurface can prove effective.
Plan Bs, Stimulators, PMXs, Purple Hazes or Brindlechutes in sizes #12-16 have been effective, too. Ants and beetles like the CFO Ant, Splitsville Beetles and Glitter Ant catching a lot of picky fish. Expect to see mayflies on the rainy, overcast days. Focus on hoppers and other terrestrial patterns on the warm, dry days.
Streamer fishing has been great with the recent bump in flows. Big Horn Buggers, Autumn Offendors, Lil Kims and Mini Dungeons are some of our favorites on Rock Creek this time of year.
Looking Forward
Sunny, warm days in the forecast may make the dry fly fishing difficult. Expect great streamer fishing and plenty of hatches as we near the end of the month.
