CURRENT REPORT
The cooler conditions have really improved the fishing up Rock Creek. Heavy rains from last week bumped the flows on Rock Creek, but it's dropping hard as of today. Fishing should be good this week!
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.
Still, hoppers, ants and beetles now the name of the game on Rock Creek. Fishing a nocturnal stone early has proven effective. 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.
Be prepared to fish up Rock Creek two ways: dry-dropper fishing and dry dropper fishing with smaller attractors.
In the evening, you'll see hatches of caddis close to dark.
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.
Smaller dry flies like the Plan B, Stimulator, PMX, Purple Haze or Brindlechute 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.
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
Strong hatches of Mahoganies, BWOs and October caddis will be here sooner than later! This is some of the most exciting dry fly fishing of the year. Streamer fishing will only get better as we approach October, too.
