Deschutes River Fishing Report – June 3, 2026: Caddis Season Peaks, 4,000 CFS, Prime Dry-Fly Conditions
Elk Hair Caddis, Stimulator, Chubby Chernobyl, Parachute Adams, Pheasant Tail Nymph, Copper John
Current Conditions
The lower Deschutes River is hitting its early-June stride with 4,000 CFS recorded at the USGS Moody gauge (#14103000) as of 5:45 AM PDT this morning — trending down slightly from last week's readings and moving in the right direction. Water temperature is a comfortable 62°F (16.6°C), squarely in the trout's prime feeding range, with clear visibility through the canyon. Both the Maupin corridor above Sherars Falls and the big-water reaches below are actively producing fish.
Hatch Activity — Caddis Season Peaks
June on the lower Deschutes is every fly fisher's dream scenario, and this week is delivering in a big way. Caddis activity is nothing short of spectacular right now — guides and shop reports describe massive evening flights that turn the air brown along the canyon banks. The classic Spotted Sedge (Hydropsyche) is the dominant species, but multiple caddis are cycling through simultaneously. PMDs (Pale Morning Duns) and PEDs (Pale Evening Duns) are popping reliably on overcast afternoons, and observant anglers are starting to spot early Green Drakes in shaded canyon sections. Hatch intensity is most consistent on cloudy days — don't overlook afternoon sessions under an overcast sky.
Top Fly Recommendations
- Elk Hair Caddis (#14–16) — the undisputed Deschutes staple; dead-drift it through riffles or skate it across flats during evening caddis flights for explosive surface strikes
- Stimulator (#12–16) — an exceptional all-day attractor; covers caddis, stonefly, and general attractor duty in one fly
- Chubby Chernobyl (#12–14) — the go-to big dry for higher flows; floats all day, supports a dropper nymph, and triggers aggressive takes from big redband rainbows
- Parachute Adams (#16–18) — versatile and deadly during PMD and PED hatches when fish are visibly rising
- Pheasant Tail Nymph (#16–18) — run it beneath an indicator between hatches; the Deschutes' mayfly population keeps this fly productive year-round
- Copper John (#14–16) — heavy enough to cut down through 4,000 CFS flows; pairs perfectly as a dropper below a Chubby Chernobyl
Access & Best Spots
At 4,000 CFS, drift boats and pontoons have a distinct advantage — the floating the classic Maupin to Harpham Flat run gives maximum water coverage and access to the most productive seams. Wade fishers should focus on Maupin City Park, Sandy Beach, and the well-worn pull-outs along Hwy 197 above Sherars Falls, where shallower tailouts remain wadeable with care. Below Sherars Falls, the sandy slots at Beavertail and Macks Canyon are holding good numbers of both redband rainbows and whitefish — the canyon is quieter down there mid-week.
Hazards & Reminders
At 4,000 CFS, the Deschutes is powerful — always wade with a sturdy wading staff, wear studs or felt soles, and never cross at unmarked spots. Sherars Falls is impassable by boat; portage is mandatory. Respect Native American treaty fishing sites near the falls — certain areas are restricted and must be honored. No emergency closures are currently in effect for the Maupin reach. Get out there this week while the caddis hatch is in full eruption — this is prime time.
