Chubby Chernobyl, Stimulator, Elk Hair Caddis, Woolly Bugger, Copper John, Pheasant Tail Nymph
๐ชฐ Salmonfly Madness: The Hatch of the Year Is ON
If you've been waiting all winter for one week on the Lower Deschutes, this is it. The Salmonfly (Pteronarcys californica) hatch is at peak intensity from Trout Creek down through Maupin, with the hatch front continuing to push toward Warm Springs. Redside rainbows are stacked along shaded canyon walls, log jams, and overhanging willows โ and they are looking up.
๐ Current Conditions (May 21, 2026)
- Flow: 3,800 CFS at USGS Moody Gauge (#14103000) โ elevated but very fishable
- Water Temp: 61ยฐF โ running warmer than average for mid-May, supercharging insect activity
- Clarity: Slightly off-color at bank edges; cleaner in mid-current seams and shaded canyon walls
- Overall: Excellent โ possibly the best dry-fly window of 2026
๐ฆ Hatch Report
The Salmonfly is the star, with big orange-bellied adults falling from cliff faces and overhanging brush throughout the day. Golden Stoneflies are providing excellent backup when Salmonfly activity cools, especially mid-canyon. Heavy Tan Caddis flights explode each afternoon โ fish that ignore the big bugs often can't resist a size #14 caddis fished flush in the film. PMDs and Blue-Winged Olives round out the menu for technical fishing during cloud cover.
๐ฃ Top Fly Recommendations
At elevated flows, presentation beats pattern โ get tight to structure. These flies are working right now:
- Chubby Chernobyl #6โ8 โ the undisputed king of Salmonfly season on the Deschutes. Slam it within inches of the bank under overhanging brush. Available at bugsnjugs.com.
- Stimulator #6โ8 (orange/red) โ a classic that never fails when the big bugs are out. Fish it as a solo dry or lead fly on a dry-dropper rig. Available at bugsnjugs.com.
- Elk Hair Caddis #14โ16 (tan/orange) โ run this off the back of your stonefly dry for a deadly double-dry setup during afternoon caddis flights. Available at bugsnjugs.com.
- Woolly Bugger #6 (black/olive) โ strip it along shaded banks at first light before the hatch kicks off. Consistently takes trophy-class redsides. Available at bugsnjugs.com.
- Copper John #12โ14 โ an excellent dropper below your big dry, mimicking emerging stonefly nymphs in the water column. Available at bugsnjugs.com.
- Pheasant Tail Nymph #14โ16 โ for midday nymphing in deeper runs when surface action slows; fish it tight to the bottom in runs 3โ5 feet deep. Available at bugsnjugs.com.
๐ Best Access Points
- Trout Creek Campground โ top of the prime hatch water; excellent wade fishing and drift boat launch
- South Junction โ productive wade access in the heart of the Salmonfly zone
- Harpham Flats โ classic dry-fly water; fish the willowed banks hard in the morning
- Maupin City Park โ convenient access and drift boat takeout/launch in the middle of it all
- Beavertail Campground โ good mid-canyon access above Sherars Falls
โ ๏ธ Hazards & Reminders
- Sherars Falls: Portage is mandatory โ do not attempt to run the falls. Indian fishing platforms are active; give all tribal fishers wide berth and respect.
- Elevated flow: At 3,800 CFS, wading requires caution and a wading staff. Felt soles or studs strongly recommended on basalt shelf rock.
- Boat traffic: Peak hatch = heavy drift boat traffic. Communicate with other boats; yield in tight canyon sections.
- Fire/camping regulations: Check current ODFW and BLM fire restrictions before your trip. Dispersed camping is permitted in most BLM sections along the river corridor.
